Tea seedling black film mulching cultivation method

Abstract

The invention discloses a tea seedling black film mulching cultivation method. The method comprises the steps that soil preparation is carried out in a conventional mode, and base fertilizer is applied sufficiently; earthing towards the center along fertilization furrows is carried out after fertilization to form planting ridges which are about 0.6 m wide and 0.10 m to 0.15 m high; the planting ridges of tea lines are covered with black mulching films flatly and tightly before tea seedlings are transplanted; black polyethylene blow molding agricultural films which are good in toughness, ageing resistant and good in shading effect are requested, the thickness of the films is 0.015 mm to 0.020 mm, the width is 0.8 m to 0.9 m, and the using amount of the mulching films is 5 to 6 kg in net weight per mu; tea seedling transplanting, seedling management, weeding, prevention and cure of diseases and pests and topdressing are carried out; the mulching films are recycled. The tea seedling black film mulching cultivation method can improve the survival rate of newly planted tea seedlings, tea gardens can be formed ahead of time for benefit acquiring, fertilizer and water can be utilized efficiently, weeds, the diseases and the insect pests can be controlled effectively, the investment of labor force and production management can be reduced, and production cost can be lowered.

Description

technical field [0001] The invention belongs to the technical field of cultivation, and in particular relates to a method for cultivating tea seedlings covered with black film. [0002] Background technique [0003] At present, the construction of newly planted tea gardens is in accordance with the standard technical requirements for planting tea seedlings: it is necessary to dig a 50×50 cm planting ditch, apply high-quality base fertilizer, backfill the mellow soil, and then transplant the tea seedlings. After transplanting, strengthen fertilizer and water management, intertillage and weeding , for pest control. [0004] However, the following problems will occur in this method in newly-built tea gardens in karst mountainous areas, which are mainly manifested in: 1. The soil cultivation layer of the newly-built tea gardens in mountainous areas is generally about 30 cm, which does not have the objective conditions for technical requirements; Subsequent management requires ...

Problems solved by technology

[0004] However, the following problems will occur in this method in newly-built tea gardens in karst mountainous areas, which are mainly manifested in: 1. The soil cultivation layer of the newly-built tea gardens in mountainous areas is generally about 30 cm, which does not have the objective conditions for technical requirements; Subsequent management requires a large number of labor forces with high skills, resulting in continuous increase in production costs, and it is difficult to implement in accordance with technical requirements; 3. Drought, pests and other disasters are serious; 4. There are certain requirements for agricultural production infrastructure such as irrigation and roads. It is difficult to standardize the production management of tea gardens

These restrictive conditions lead to low survival rate of new tea seedlings, weeds grow wildly in tea gardens, the normal growth of tea seedlings is severely hindered, tea gardens are slow to grow, economic benefits are poor, and tea farmers’ income is reduced, which seriously damages the enthusiasm of tea farmers for production and greatly affects sustainable development.
