Method for multipoint grafting of fruiting mother branches by aid of Chinese chestnut skeleton branch bald sections

Abstract

The invention relates to a method for multipoint grafting of fruiting mother branches by the aid of Chinese chestnut skeleton branch bald sections. The method comprises steps as follows: (1) garden plot selection; (2) rootstock selection; (3) scion selection; (4) scion storage; (5) grafting; (6) grafting of main points; (7) management after grafting and (8) disease and pest control. The high-quality fruiting mother branches are grafted by the aid of the Chinese chestnut bald sections, the inside is rapidly enriched, the operation is simple and practical, the return period is short, and the purposes of high yield and stable yield can be achieved; with the adoption of multipoint bark graft of the fruiting mother branches by the aid of the bald sections, fruits can be obtained in the chestnut orchard in the same year, the yield in three years can be as high as 564.48 kg after grafting, and the method has important application value.

Description

technical field [0001] The invention relates to the field of fruit tree grafting, in particular to a method for multi-point grafting of bare chestnut trunk branches to fruiting mother branches. Background technique [0002] Chestnut is a plant of the genus Chestnut of the Fagaceae, native to China and distributed in Vietnam, Taiwan, and mainland China. Chestnut is one of the earliest fruit trees cultivated in my country, with a cultivation history of about 2000 to 3000 years. At present, my country's chestnut planting area is about 18 million mu, widely distributed in more than 20 provinces (autonomous regions, municipalities) across the country, mainly concentrated in Shandong, Hebei, Henan, Hubei, Anhui, Zhejiang, Liaoning, Guangxi, Beijing and other places. [0003] Chestnut nuts are rich in nutrients, among which the starch content is similar to rice, flour and other grains, the protein is similar to flour and more than 1 times higher than sweet potato, the fat is 2 tim...

AI Technical Summary

Problems solved by technology

[0007] Although the above-mentioned techniques have increased the yield of chestnuts, however, because the mountain chestnuts are dominated by fruiting branches on the periphery, the inner chamber is empty, and the backbone branches are too large and have no fruiting branches or the number of fruiting branches is very small, resulting in low yields of mountain chestnuts. Grafting technology is not very good for increasing chestnut production
