Problems solved by technology

I have tried to use pine branches, dustpan branches, and straw curtains to prevent wind and keep warm, but because there are eggs of cypress, rice planthopper, blue leafhopper, and red spider on them, they are easy to transfer to tea trees, which brings Severe pests and diseases, so had to give up
Whenever winter comes, without active and effective measures, we can only passively accept the situation that the tea trees freeze to death or reduce production. Year after year, the losses accumulate

Embodiment Construction

[0015] First, select high-quality wheat straw that has been stored for 3 years without mildew and insect eggs, soak it in 3% white lime water for 1 day to achieve the disinfection effect, and then expose it to the sun for 2 days before storing it for later use. At the same time, the preparation of organic fertilizer is carried out. Collect pigs, cattle, sheep, chickens, rabbits and other livestock, poultry manure and soil in a ratio of 1:1, mix evenly, let it ferment naturally, and use it after 3 months. For tea trees planted in mountainous sandy land, the soil used is preferably red soil. The organic fertilizer produced in this way is a caloric fertilizer, which is easily absorbed by the roots of the plants and facilitates the good growth of tea trees.

[0016] Between "Great Cold" and "Little Snow", spread the organic fertilizer prepared above in the tea garden, 3000 kg per mu. Carry out irrigation and watering after fertilization, after 2 days, plow and hoe to loosen the s...

Abstract

The invention provides a wintering antifreezing conservation technology for tea-plant, which relates to a planting conservation technology for tea-plant, in particular to a wintering antifreezing conservation technology of tea-plant in area north of the Yangtze River. The technology comprises the following steps of: raw material preparation, fertilization and irrigation, floor covering, film covering, film withdrawal, and the like. The fertilization and the irrigation are carried out within Great Cold (24th solar term) and Lesser Snow (20th solar term); wheat straws are paved on the land among the tea-plant; and plastic films cover at the north side of the tea-plant and are torn off within the vernal equinox and the Tomb-sweeping Day in ensuing year and paved on the wheat straws among the tea-plant. By improving tea-plant endoplasm and adopting measures of wind resistance and heat preservation, the invention effectively improves the wintering survival ratio of the tea-plant and also plays the roles of drought and moisture resistance, soil conservation, pest and disease prevention as the plastic films are correctly used.

Description

technical field [0001] The invention relates to the planting and maintenance technology of tea trees, in particular to the anti-freezing and maintenance technology of tea trees in Jiangbei area for overwintering. Background technique [0002] Since the end of the 1960s, northern regions represented by Shandong Rizhao and Qingdao began to transplant tea trees from the south of the Yangtze River to the local areas. After several years of experimental work, they gradually achieved success and achieved large-scale development in recent years. Taking Rizhao City as an example, the area of ​​mature tea gardens has reached 126,000 mu, and the area of ​​young tea gardens has reached 21,800 mu. The tea industry has become one of the main economic pillars of the local area. Because Jiangbei tea has the characteristics of thick leaves, brewing resistance, and rich aroma, it is deeply loved by consumers, and a number of famous Jiangbei green tea brands have emerged. [0003] However, d...
