A kind of shading cultivation method of tea tree

Abstract

The invention discloses a shade culture method for a tea tree. The method comprises the following steps of: A, shading through a black shading net serving as a tea garden shade material; B, in a tea garden shade period, starting to perform shading treatment after tea burgeoning in spring, directly covering the tea tree by using the black shading net for shading on a clear day, starting to perform shading treatment after tea burgeoning in summer and autumn, and directly covering the tea tree by using the black shading net for shading; C, in the aspect of tea garden shade time, removing the shading net after the tea tree is shaded in spring, and removing the shading net after the tea tree is shaded in summer and autumn; D, in a tea garden shade method for directly covering the shading net for shading through a tea tent, not picking tea leaves or trimming between branches at intervals in the process of mechanically picking the tea leaves in summer of the previous year and trimming the tea tree in autumn and winter; and E, not covering the shading net at night and on rainy days. The culture method is simple and convenient and is convenient to operate and low in cost, the tea quality is obviously improved, the yield of high-quality fresh tea leaves is improved, and particularly the yield of high-grade high-quality fresh green tea leaves which are suitable to be processed in summer and autumn is improved.

Description

technical field [0001] The invention relates to the field of tea tree cultivation, and more specifically relates to a method for shading tea tree cultivation, which is especially suitable for subtropical hilly tea areas. Background technique [0002] Tea tree is an accompanying tree species in the forest. It is a shade-tolerant plant and likes diffuse light. The light saturation point is between 35~50klx. However, hilly tea gardens often have continuous sunny weather from May to September, and the light intensity generally exceeds 50klx between 9:00 am and 4:00 pm, and often exceeds 100klx at noon. Continuous strong light radiation is often accompanied by continuous high temperature weather. Under high temperature and strong light conditions, the net photosynthetic rate of tea trees is negative, and the "siesta phenomenon" of tea tree photosynthetic diurnal changes occurs, which is not conducive to the sulfur- and nitrogen-containing flavors of amino acids and proteins in te...

Problems solved by technology

Although the shading effect of covering the sunshade net with steel greenhouse skeleton is good, the cost is too high. It requires a one-time investment of more than 40,000 yuan per hectare. Farmers generally cannot afford it, and the operation is troublesome. Tea farmers cannot accept it during promotion and application.
