Novel summer tea shoot cuttage reproduction method for non-subsoil rice field

Abstract

The invention particularly relates to a novel summer tea shoot cuttage reproduction method for the non-subsoil field. The novel summer tea shoot cuttage reproduction method is performed in the rice field in summer for cutting and reproducing tea shoots without paving yellow subsoil. The novel summer tea shoot cuttage reproduction method includes steps of treating microorganism environment, cutting shoots, finishing the soil and furrowing, compacting pulverized soil, cutting in a greenhouse and managing after cuttage before cuttage in the rice field. By the novel summer tea shoot cuttage reproduction method, the process for paving the yellow subsoil is omitted, which can save cost by CNY 1920 to 2000 as compared with that of a conventional seedling cultivation technology; water irrigation and sun exposure are performed to reduce bacteria. In addition, air temperature is high in summer, cuttage tea shoots are fast in rooting and growth, survival rate can be increased by 10%, and delivery rate of qualified seedlings is increased by 12%; the qualified tea shoots can be increased by 150,000 per mu, and CNY 3000 can be increased.

Description

technical field [0001] The invention belongs to the field of economic crop tea tree seedling expansion breeding method, and in particular relates to the new field of breeding tea seedlings without yellow core soil in paddy fields, paddy field soil treatment, new method of tea tree cuttings processing, selection of cutting period and the like. Background technique [0002] The existing cutting propagation technology of tea seedlings is the seedling raising method of spreading yellow heart soil on dry land: cuttings are carried out from mid-September to early December of the first year, and a suitable dry land is selected, and the short ear cutting method of spreading yellow heart soil is adopted. Spread yellow core soil without sand and gravel on the seedbed before cutting, with a thickness of 6-8cm. Generally, 25-30 cubic meters of yellow core soil should be spread on a 667 square meter to reduce diseases and weeds in the nursery, promote rooting and increase the rate of see...

AI Technical Summary

Problems solved by technology

[0003] The existing method of raising seedlings with yellow core soil on dry land is too high in production cost and requires a lot of labor. Due to the poor traffic conditions in mountainous areas, the transportation of yellow core soil is extremely inconvenient, and even in places where there is no yellow core soil, cutting seedlings cannot be raised.

In addition, in the autumn and winter cutting seedlings, the short panicle callus will suffer from the severe cold in winter before recovery, and the survival rate will be affected.

In order to keep the seedbed moist and keep warm in the cold winter, tea farmers need to cover another layer of agricultural mulch on the sunshade net, which further increases the cost and labor.
