Mango grafting method using green braches with leaves

Abstract

The invention discloses a mango grafting method using green braches with leaves. The method comprises the following steps: preparing semiligneous green braches with leaves as scions; cutting the scions, soaking and wetting the cut scions with clear water for 2 hours at most, taking the scions out of the clear water and grafting the soaked scions on root stocks, and then binding grafting cuts in an alternate unenclosed manner with discharge outlets reserved; and cultivating the grafted seedlings in a plastic thin film heat-insulation and moisture-preservation tunnel under a sun shelter. According to the invention, the grafting method using green braches with leaves is adopted; the scions used in the method are low in degree of lignifications, the histocyte is active, callus is formed very quickly; moreover, the reserved leaves can conduct photosynthesis to produce nutrient substances to support the regrowth of the grafting cuts; the grafting survival rate is higher than 98%; in addition, if only semiligneous green braches are available, the grafting method can be implemented all the year round regardless of the seedling age of the root stocks; therefore, the problem that the survival rate of the traditional stiff branch grafting method is low is solved, the grafting survival rate is improved, the seedling cultivation cycle is shortened, the seedling cultivation cost is lowered, the grafting survival rate is free from the influence of seasons and the thickness of the root stocks. The mango grafting method using green braches with leaves is applicable to large-scale industrial seedling cultivation.

Description

technical field [0001] The invention relates to the field of agricultural science, in particular to a method for grafting mango green branches with leaves. Background technique [0002] Mango (Mangifera indicaLinn) belongs to the Sumac family (Rhoideae Engl), Mango (Mangifera Linn), a perennial evergreen tree fruit tree, native to India and Malaysia. Mango is known as the "King of Tropical Fruits" because of its good color, fragrance and taste, and rich nutrition. Mangoes are widely distributed. There are more than 70 countries producing mangoes in the world, 90% of which are concentrated in India, Pakistan, Bangladesh, Myanmar, Malaysia and other countries in Asia; eastern and western Africa, Tanzania, Zaire, and Brazil in the Americas Mangoes are cultivated in China, Mexico, Florida and Hawaii in the United States; Taiwan, Guangdong, Guangxi, Hainan and southern Fujian in China, and mangoes are planted in the east, west and south of Yunnan. Guizhou Province (formerly Gui...

Problems solved by technology

Guizhou is a new area for mango development, and grafted seedlings are very scarce. In order to speed up the breeding of mango grafted seedlings and meet the needs of its industrial development, the inventor began to conduct mango introduction observations and grafting seedling experiments in 1991. After more than 20 years of research, hard branch grafting seedlings , the rootstock cultivation time is not less than 12 months, and it takes more than 20 months from rootstock cultivation to out of the nursery. Generally, the survival rate of grafting is 50-60%, and the highest is 80%. Moreover, the requirements for rootstock, scion and grafting time are very strict, and the survival rate of grafting is limited by The influence of rootstock thickness, scion maturity, grafting season, and grafting method leads to high cost of seedling cultivation, which is difficult for fruit growers to accept
