Embodiment 1

[0047]S1. Rootstock preparation: select plump single-embryo seeds, soak them in 500 times the 50% chlorobromoisocyanuric acid soluble powder solution for 10 minutes, then dry them and sow them on sand beds. After the seedlings emerge from the ground, transplant them into nutritional bags. Choose a base with a diameter greater than 5mm. And 100 2-week-old seedlings with a height greater than 10 cm, cut off the upper stems and leaves 10 cm from the ground.

[0048] S2, scion preparation: select the good variety semi-lignified branch with diameter less than 1.5cm, wrap wet towel and keep moist, soak 5min with 50% chlorobromoisocyanuric acid soluble powder solution of 800 times before grafting, place 1min to dry surface liquid, cut Become a 5cm stem segment with a terminal bud, keep 1 blade and cut off 80% of the leaf area, cut off the cross section, cut the opposite sides of the lower end of the stem segment into a wedge shape, the slopes on both sides of the wedge are equal, and ...

Abstract

The invention provides a mango seedling grafting method, belongs to the technical field of fruit tree grafting, solves the problems of long seedling period, low survival rate and the like in the prior art, can be used for grafting when the diameter of the base part of a stock is greater than or equal to 5mm, realizes sowing and grafting in the current year and outplanting in the second year, greatly shortens the mango seedling period, and improves the yield. The survival rate is high and can reach 98.4%, and the method is easy to operate and suitable for industrialized seedling culture.

Description

technical field [0001] The invention relates to the technical field of fruit tree grafting, in particular to a method for grafting mango seedlings. Background technique [0002] Mango (Mangifera indica L.) is an evergreen tree belonging to the family Anacardiaceae. It is one of the five tropical fruits. It has beautiful shape, attractive color, sweet flesh, unique fragrance and rich nutrition. It is known as the "king of tropical fruits". , mainly distributed in Hainan, Guangxi, Yunnan, Sichuan, Guangdong and Fujian in China. The national mango industry is developing very rapidly. By 2021, the mango planting area has exceeded 5 million mu. With the development of the mango industry, the demand for fine varieties of seedlings continues to increase. At present, the seedlings of fine mango varieties are all grown by grafting. The survival rate of traditional grafting seedlings is low, and the requirements for rootstocks and scions are relatively high. The rootstocks used gener...
