Kiwifruit top-grafting method

Abstract

The invention relates to the field of the kiwifruit cultivation, in particular to a kiwifruit top-grafting method. Wild kiwifruits which are relatively high in disease and pest resistance and relatively wide in adaptability and grow strongly are cultivated in a kiwifruit production orchard, through reasonable water and fertilizer management, strong stock is cultivated according to a normal kiwifruit cultivation and shaping technology, two strong branches are maintained at the position, 1.8 m away from the ground, of a main stem of the stock and extend along the two ends of a pull wire of a cultivation frame, strong side branches on the branches are maintained, and unnecessary branches of the main stem are removed. According to varietal characteristics of kiwifruits, kiwifruit scions with good adaptability and high economic benefits are selected to be subjected to top grafting at the ends of the branches, the purposes are achieved that the kiwifruits in the orchard bloom and fruit in the same year and are put into production, wild stock grows strongly, the high yield of the kiwifruits is promoted, and at the same time the survival rate of kiwifruit cultivation is increased.

Description

technical field [0001] The invention relates to the field of kiwifruit cultivation, in particular to a method for high-level grafting of kiwifruit, which is applicable to the production and cultivation of kiwifruit in any kiwifruit production area. Background technique [0002] Kiwifruit is a vine deciduous fruit tree of the Actinidiaceae Actinidia genus. The fruit is rich in vitamin C, amino acids, polysaccharides and folic acid and other nutritional and functional ingredients. As a new fruit industry, it is very popular among people. Kiwi fruit is native to China. At present, there are still a large number of wild kiwifruit germplasm distributed in my country, such as wild kiwifruit, wild kiwifruit, kiwifruit, kiwifruit, etc., which often have developed root systems and strong growth. All performed well, and had high utilization value for the innovation and high-efficiency production and cultivation of kiwifruit resistant germplasm resources. [0003] The production and c...

AI Technical Summary

Problems solved by technology

[0003] The production and cultivation of kiwifruit mostly use grafted seedlings. Usually, wild kiwifruit with better adaptability is selected as the rootstock for grafting and then planted. At this time, the plants are relatively small and the root system is not yet developed. Because the grafting site is too low, it is easy to be buried during the planting process, resulting in rot or infection of the grafting site, the planting survival rate is low, and the growth of the plant is weak; The root system of the plant is rotted and the whole plant dies due to being buried in the soil

In addition, kiwifruit low-level grafted seedlings grow relatively slowly, with weak growth, long fruit-setting and production periods, and increased cultivation and management costs in the early stage, which affects the economic benefits of planting
