Seedling cultivation method for kiwi fruit

Abstract

The invention provides a seedling cultivation method for kiwi fruit. The seedling cultivation method comprises the following steps of: grafting which is performed from the end of December to next January; sand storage, namely, seedlings subjected to the grafting are stored by river sand indoors; and planting of the seedlings in a nursery garden from February to the beginning of March. According to the invention, the grafting is performed in winter to avoid busy farming seasons of spring and summer, and the grafting time can be reasonably scheduled at daytime or at night as the grafting is performed indoors. After the seedlings subjected to the grafting are stored by the river sand indoors, most of the seedlings form callus at graft unions when being transplanted since an indoor temperature is high, thereby being beneficial to improving the rate of survival of the grafted seedlings. By virtue of the seedling cultivation method, the rate of survival of the grafted seedlings can reach 99%; and the pruning of stocks in a bleeding period is avoided, thus the nutrient loss of the stocks is reduced.

Description

technical field [0001] The invention relates to the field of kiwifruit production, in particular to a method for rapidly improving the emergence rate of kiwifruit seedlings. Background technique [0002] Kiwi grafting is generally divided into spring, summer and autumn grafting. [0003] Kiwi fruit grafting is generally carried out in spring from February to March, and the temperature begins to rise at this stage; however, due to the early injury of kiwi fruit (late February), the long injury period (generally about 50 days), and the large injury flow, it affects grafting. Survival rate, where conditions permit, the scion can be stored in a cold storage to postpone the grafting after the injury; split grafting, cutting grafting and bud grafting are all better. Summer grafting is generally better in June. The start time of grafting in summer depends on the maturity of the scion and the thickness of the rootstock. The earlier the better, especially in high temperature and d...

AI Technical Summary

Problems solved by technology

If the temperature is too high too early, the survival rate is too low; if it is too late, it is not conducive to healing, and at the same time, the growth is not sufficient, and the ability to survive the winter is poor.

[0005] Due to grafting in February to March or May to June, there are many agricultural affairs in spring, and the grafting time is short. At the same time, there is a lot of rain or high sunshine intensity in spring and summer, and the labor intensity of outdoor grafting is high; especially in places where there are few grafting technicians, When producing seedlings in large quantities, it is necessary to invite professional and technical personnel to graft in spring and summer, which will cause a shortage of personnel at a certain stage
