山地幼龄茶园夏秋季免耕栽培技术研究

在重庆山地茶园中,主要研究了夏秋季免耕栽培技术及其对水土流失的保持效果,并提出:夏秋季离地4~7 cm时修剪杂草1~3次,既可有效控制水土流失、又能降低管理成本,是实行免耕较为理想的杂草管理模式;茶树行间10月种植绿肥翌年5月翻埋并配施追肥,可改良土壤结构,增加土壤养分,提高茶树生长势,形成土壤培肥模式。两种管理模式的配套,既培肥土壤又很好地控制了土壤侵蚀问题,是山地幼龄茶园较好的保持可持续发展的栽培技术及管理模式。

Research on Cultivation Techniques of Zero Tillage in Hilly Infancy Tea Garden in Summer and Autumn

The soil erosion control measures adopted the zero tillage technique in hilly infancy tea garden in summer and autumn in Chongqing is studied and it is put forward that cutting grass 1-3 times while the weed plant 4-7 cm high is an ideal management model of weed. This method not only controlls the soil erosion effectively but also reduces the management cost. Planting green manure in October followed by burying and additional fertilizering in May the next year can improve soil structure,soil nutrition and the growth faculty of the tea tree. The integration of the two kinds of management model can increase the fertility of the soil, resolve the soil erosion problem. It is an ideal model of the cultivation technique and management for hilly infancy tea garden to keep sustainable development.
