Cây mai vàng là loại cây dễ trồng và chăm sóc, ưa ẩm và ánh sáng nhưng không chịu được úng. Nếu muốn cây ra hoa đúng dịp tết và có vườn mai đẹp, bạn có thể lựa chọn ghép mắt cây mai vàng để đạt được hiệu quả như mong muốn. Dưới đây là kỹ thuật ghép mắt cây mai vàng đúng cách:
Xác định thời gian ghép cây mai vàng
Thời điểm thích hợp để ghép cây mai vàng là từ tháng 10 đến tháng 4 âm lịch. Phương pháp ghép mắt ngủ được áp dụng phổ biến trong mùa ghép mai. Đây là phương pháp đơn giản và tiện lợi, khi lấy mắt lá chưa lên mầm để ghép.
Có thể ghép phôi mai vàng bến tre vào tháng 2 âm lịch, khi cây đã phục hồi trở lại, bắt đầu đâm chồi mới và phát triển nhanh, nhưng kết quả sẽ không cao bằng thời điểm cuối tháng 3 trở đi. Lúc này, cây mai đã hoàn toàn bình phục, bắt đầu tích trữ nhựa trong thân, lá, cành.
Trong mùa mưa, nếu muốn ghép bổ sung hoặc ghép mới một cây mai, có thể áp dụng hai phương pháp chính là ghép cắm đọt hoặc ghép mắt kim.
Chọn gốc mai vàng
Để ghép cây mai vàng thành công, bạn cần chọn gốc mai vàng sinh trưởng khỏe, dễ ghép, dễ thành công, đủ sức mang trên mình nhiều giống mai khác. Có thể dùng gốc mai vàng (loại mai đang được trồng phổ biến ở Nam bộ) hoặc tốt nhất là gốc mai tứ quí.
Những gốc cây này càng lớn càng tốt, dùng cưa cắt ngang thân cây cách mặt đất khoảng vài tấc đến một mét (tùy theo thế của cây sau này định tạo là cao hay thấp) sau khi cưa chăm sóc (bón bổ sung thêm phân, tưới đủ nước) chu đáo để cây nẩy tược. Chờ cho tược lớn cỡ điếu thuốc lá là có thể ghép được (để cho dễ phân biệt tạm gọi mỗi tược mới ra sau này là một gốc ghép, còn gốc cây mẹ vừa được cưa bỏ phần ngọn là thân chính).
Công tác chuẩn bị
Khi thực hiện ghép mai vàng, bạn chỉ cần chuẩn bị các dụng cụ như dao lam và băng keo non.
Kéo cắt cành bén để tránh sự dập nát cành, 1 lưỡi lam mới để chuốt nhánh ghép cho phẳng, dây nilon to bản, mỏng để quấn quanh chỗ ghép, dây cao su hoặc nilon để buộc chặt chỗ ghép, một lọ dung dịch kẽm, vật liệu trám nứt, vật liệu phủ kín. Các dụng cụ này cần phải được sát khuẩn trước khi sử dụng để tránh vi khuẩn làm hại cây.
Cách ghép mắt cây mai vàng
Bước 1: Chuẩn bị cành mai, lựa chọn nhánh trên cây mẹ có mắt lá đẹp, còn sống, không bị sâu bệnh, chắc chắn. Sử dụng dao lam để cắt cành mai tại vị trí sát khỏe nhất.
Bước 2: Tiếp tục cắt cành mai thành từng khúc nhỏ với chiều dài khoảng 10-12cm và bóc toàn bộ lá để chỉ còn lại mắt lá trên.
Bước 3: Lấy dao lam cắt tạo hình vát như một chiếc lá tại vị trí cách mép 2-3mm từ mắt lá, bóc toàn bộ vỏ cây ở phần đó để lộ mô xanh bên trong.
Bước 4: Cắt một khúc nhỏ từ cành mai cắt được ở bước 2, rút bỏ mắt lá để chỉ còn lại mắt ngủ.
Bước 5: Sử dụng dao lam để chuốt phẳng nhánh cây mai, cắt vào đó một đường rãnh vừa đủ cho mắt ngủ, chỗ này sẽ được đặt mắt ngủ của cây mai vàng vào.
Bước 6: Đặt mắt ngủ của cành mai vào đường rãnh vừa tạo ở bước 5, đảm bảo rằng mắt ngủ của cành mai sát vào mô xanh của nhánh mai vàng.
Bước 7: Sử dụng dây nilon để quấn quanh đầu ghép, đảm bảo mắt ngủ của cành mai và mô xanh của nhánh mai vàng bám chặt vào nhau.
Bước 8: Dùng dây cao su hoặc nilon quấn quanh cành chừng 3-5 vòng từ ngoài vào trong rồi buộc chặt. Bao nilon nhúng nước, nên nhớ để lại trong bao vài giọt nước, chừng 1cc, để nước trong bao sẽ làm cho cành lá bớt khô. Chụp bao nilon và dùng dây buộc chặt.

Lấy giấy báo bao bên ngoài bao nilon, không che kín hoàn toàn, phải để cho ánh sáng lọt vào. Lần lượt ghép các nhánh còn lại cho đến hết. Mỗi cây chỉ nên ghép tối đa là 6 cành mới, những cành cũ cắt bỏ bớt, song nên để lại một vài cành cũ để cây thở.
Đặt chậu mai vào chỗ thoáng mát, có nắng gió, khoảng 4 giờ/ngày. Độ 3 ngày sau trong bao nilon xuất hiện những giọt li ti như sương mù, tiếp tục tưới cây như bình thường. Khoảng 15 ngày lá non đã lớn, tháo giấy báo, và 5-7 ngày sau tháo bao nilon. Sau đó dưỡng mai ghép cho đến khi lá lớn và chờ khi đâm chồi lần thứ hai, thứ ba mới tháo dây nilon quấn quanh chỗ ghép.

The star topped 100 receptions and 1,400 yards for the second straight season and doesnt appear to be slowing down. Browns ability to run every type of route imaginable makes it easy to see why hes Ben Roethlibergers favorite target. Theres a chance that Brown could lose targets to either or this season, but it seems unlikely that either one of those wideouts will do enough damage to Browns standing that the veteran wont once again challenge to be the top fantasy option at his position.Auction...............$44Bye Week.............6Bryant has been knocking on the door to be the top receiver in for some time now. If it werent for stretches where it seems the offense forgets about No. 88, its not unrealistic to think he could have already achieved that. Nonethele s, Bryant will remain the centerpiece of Dallas pa sing game and could have a bigger role in the attack if the Boys Scott Oberg Jersey new backfield committee falters at any point. Either way, if things go according to plan in 2015, Bryant is a lock to once again be a top-five fantasy wide receiver and could threaten to finish the year atop the positional rankings.Auction...............$44Bye Week.............92014 was a frustrating season for ... and anyone who had him on their fantasy roster. The dynamic receiver was hobbled by injuries for a significant portion of the season, and his numbers suffered accordingly. Johnson failed to top 1,100 yards for the first time since 2009 and fell outside of the top 10 fantasy receivers. For now, theres little reason to be alarmed by what happened last year -- is still . might be a bigger part of the offense, but will still do his best to get the ball in the hands of Detroits best playmaker consistently in 2015.Auction...............$43Bye Week.............7Thomas posted his best overall statistical season in 2014, setting career-highs in receptions and yards. It helps that was the man throwing the football. It also helps that Thomas is both a bonafide deep threat as well as a player who can take a short throw and turn it into a long play. Even though there are long-term questions about Mannings arm strength and ability to get the ball down the field, Thomas versatility (and the departure of both and ) should continue to make him the top target in Denvers offense. Hell be one of the first five wideouts off the board in most fantasy drafts.Auction...............$41Bye Week.............7After a couple of seasons of being overlooked, Nelson is finally getting his due as one of the best receivers in the game. The Packer playmaker established new career-highs in receptions and yardage, while topping 1,200 receiving yards for the third time in four seasons. Entering his eighth season in the league, Nelson remains the favorite target of and should have more than 100 balls thrown his way for yet another season. Fear not over the presence of . There are plenty of opportunities to go around in Green Bays offense and Rodgers is adept at spreading the wealth.Auction...............$40Bye Week.............11What can you say about Jrs rookie season that hasnt already been said? His catch-for-the-ages was the highlight of a season that saw him finish as a top-five fantasy receiver despite mi sing the first four games of the season. Beckhams talent is Sam Hilliard Jersey undeniable, but he was also helped by the absence of , who mi sed most of the season with a knee injury. Cruzs anticipated return is likely to cut into some of Beckhams targets, but its apparent that Beckham has earned his spot as the top target in Big Blues offense ... and fantasy rosters as well.Auction...............$38Bye Week.............10Jones entered 2014 with concerns that his surgically repaired foot would slow him down. Turns out, those fears were unfounded. The star had his best season as a profe sional, topping 100 receptions and 1,500 yards for the first time in his career. With on the downside of his career, and the still feeling the effects of Tony Gonzalezs retirement, fantasy managers can expect to keep looking in Jones direction. New offensive coordinator Kyle Shanahans system could also be a boon for Jones, as it favors the top wideout heavily. If the star wideout can boost his touchdown numbers in 2015, a top-three fantasy finish certainly isnt out of reach.Auction...............$34Bye Week.............10 scratched the surface of what he could do in 2013. In 2014, he truly broke out to become one of the NFLs better playmakers. Now, in 2015, Hilton is the undisputed leader of the receiving corps. Playing in an offense helmed by , Hilton will be the number one option in Indys pa sing game. That alone should be enough to help vault the speedster into the top 10 among fantasy wideouts this season. The only concern is whether there are too many mouths to feed with and rookie joining a cast that already includes , and . Its not a concern that should trouble you during your fantasy draft.

Cobbs numbers have improved dramatically in each of his three full seasons with the club, culminating with career-highs acro s the board in 2014. Up next, Cobb is aiming for his first 100-catch campaign -- something that is well within reach with as his quarterback. There is also an outside chance that Cobb could supplant as the top target in Green Bay.

It was a role he ostensibly shared with last season, but with the veteran moving on to the , there is no longer any doubt. Whether Jeffery finds the kind of bromance with quarterback that Marshall had remains to be seen. What is clear is that having highly-touted rookie drawing attention on the other side could help Jeffery end up in more one-on-one matchups. Regardle s, 2015 has an excellent chance of being the year we see return to the top 10 fantasy scorers among wideouts.Auction...............$37Bye Week.............7By the numbers, 2015 was the worst season of s career, although much of that can be blamed on injuries that slowed the playmaking wide receiver for stretches of the season. Even still, Green was able to finish among the top 25 fantasy receivers. Unfortunately, plenty of people drafted him expecting more. Those people should regain their optimism this season. If Green can remain healthy, he should return to his perch among the upper echelon of fantasy wideouts. It definitely helps that the have yet to find another receiver who can carry the load in the event Green cant carry out his pa s-catching duties. Nothing helps your value like being irreplaceable Jon Gray Jersey .Auction...............$15Bye Week.............8The expectation was that s fantasy totals would drop when he left Philadelphia for Washington. While that expectation came true, the fall wasnt as dramatic as some would have expected. Jackson stepped in and immediately surpa sed as the teams top receiver. Even with Washingtons uncertainty at quarterback, dont look for Jacksons targets or fantasy totals to be too far off from last season. The only downside is that the Cal product no longer offers return yards for owners who play in leagues that reward for that particular stat. Nonethele s, Jackson should be a solid choice as a No. 2 fantasy receiver. Auction...............$29Bye Week.............9Entering his third NFL season, Hopkins is now the No. 1 in the pa sing game. With now collecting mail in Indianpolis, Nuk will be expected to pick up his production -- something he proved he could do with his performance last season. The one thing that could slow Hopkins this season is the lack of a consistent quarterback. Regardle s of who wins the inevitable training camp battle between and , fantasy fans arent likely to be very enthused. This is where youll need to believe in Hopkins talent and trust that hell put up good enough numbers to be a high-end WR2, as he did last season with other mediocre quarterbacks. Auction.......... David Dahl Jersey .....$28Bye Week.............7To call Sanders first season in Denver a succe s would be an understatement. The diminutive receiver topped 100 receptions and 1,000 yards for the first time in his five NFL seasons, and broke into the ranks of top 10 fantasy receivers. With no longer plying his trade in Denver, that should open up opportunities for Sanders to work as a slot receiver -- not a bad gig in a -led offense. It would be a surprise to see Sanders drafted among the top 10 fantasy wideouts in 2015, but hes a player who certainly has WR1 upside.Auction...............$21Bye Week.............8In what was the Year of the Rookie Receiver, Matthews was one of the bigger surprises. The wideout worked his way up the rankings and eventually helped make expendable in Philadelphia. This season, well learn whether Matthews is ready for his new role as the Iggles No. 1 receiver. Head coach Chip Kelly believes that his system can help his players succeed ... not the other way around. If thats really the case, then Matthews could be primed for bigger and better things in 2015.Auction...............$23Bye Week.............11Cooks fired out of the gate in 2014 and looked to be one of the rookie wideouts that everyone would be takling about at the seasons end. That is, until a broken thumb ended his season prematurely. This year, Cooks is back and should be a large part of New Orleans revamped offense. () is gone and is far from the player he once was. That makes Cooks the No. 1 receiver almost by default. Thats not to slight his talent, though, as this kid can play. The should find a number of creative ways to get the football into his hands this season. Hopefully he picks up where he left off last year and fulfills the potential everyone saw in him.
