茶园覆盖纱网进行设施栽培 ,利用纱网隔虫 ,保护天敌 ,应用天敌和农艺措施控制茶树害虫 ,不用化学防治 ,维护茶园生态平衡 ,提高茶叶品质和产量。研究结果表明 ,纱网茶园的害虫种类和数量明显减少 ,天敌种群数量增加尤其是蜘蛛 ,全年没有使用农药防治害虫 ,而露天茶园全年用农药防治害虫 5 7次 ,鲜叶产量增加2 4 13% ;另外 ,纱网还有改善茶园小气候的效果 ,冬季保温防冻和夏季降温抗旱 ,提高茶叶品质 ,经济效益和社会效益明显。

Weed damage in tea garden,especially in junior age tea garden was an important biodamage in tea production.Usually,the manual control cost more time and more funds without good effect,and chemical control had good effect but was harmful to field environment.On the other hand,no weed cover in soil could cause erosion.The trial of weed ecological control showed it was a good way to control the weed growth by planting pasture plants like podbearing plant between the rows of tea trees and fully covering the vacancy...

Weed damage in tea garden,especially in junior age tea garden was an important biodamage in tea production.Usually,the manual control cost more time and more funds without good effect,and chemical control had good effect but was harmful to field environment.On the other hand,no weed cover in soil could cause erosion.The trial of weed ecological control showed it was a good way to control the weed growth by planting pasture plants like podbearing plant between the rows of tea trees and fully covering the vacancy niche areas.The pasture plants not only provided feed with the increasing gain of more than 15?000$/m2,but also helped to water and soil conservation and environmeat protection.

本文介绍一种新技术———生态控草技术。茶园草害,特别是新辟茶园和幼龄茶园草害是茶叶生产的重要生物灾害。传统的人工除草耗工耗资,成效甚差,化学除草又污染环境。山地茶园无杂草使地面覆盖度下降,造成水土流失,不利于山地茶园水土保持和环境保护。生态控草技术的核心是在茶树空行间按一定的规范和密度种植豆科牧草,使牧草占据行间的空白生境,抑制杂草滋生,增加茶园覆盖度,降低雨水径流速度,防止水土流失。豆科牧草还为养畜提供饲料,每公顷茶园增加纯经济效益15000元以上。

Tea plantations in the subtropical hill region faced much ecological problems, such as:soil leanness, seasonality arid, external environmental pollution, simple ecological component, ecological deterioration, etc. These made tea quality worse, harmful substances such as residues of pesticides exceeded standard, and lowefficient production. Planting arbors around and between the tea plantations(density is 120150 per hectare), or covering the tea with sunshade networks, which can reduce soil temperature and increase...

Tea plantations in the subtropical hill region faced much ecological problems, such as:soil leanness, seasonality arid, external environmental pollution, simple ecological component, ecological deterioration, etc. These made tea quality worse, harmful substances such as residues of pesticides exceeded standard, and lowefficient production. Planting arbors around and between the tea plantations(density is 120150 per hectare), or covering the tea with sunshade networks, which can reduce soil temperature and increase the air relative humidity under drought conditions in summer and autumn;some other measures were application, such as :clover is planted or straw is mulched, which can increase soil water content and natural enemy amount and control growth and propagation of pest, and improve soil structure of tea plantations, and increase the soil organic matter and available N,P,K. The studies showed:planting arbors(fruit tree, medicinal plants, ecological forest and economic forest,etc.)around and between the tea plantations, and covering the tea with sunshade networks, and planting clover or mulching with straws, and so on, formed diversity of ecosyetems, which increase natural enemy amount and species, using fewer pesticide and fertilizer, combining agriculture and physical protection, using fewer pesticide and fertilizer, in order to realize tea safety and hiefficient production.

亚热带丘陵山地茶园普遍面临土壤贫瘠,季节性干旱严重、外界环境污染、生态组分简单、生态环境恶化等生态问题,造成茶叶品质下降,农药残留等有害物质超标,茶叶生产效益低。夏秋季高温时茶园覆盖遮阳网可降低土壤温度,提高茶园湿度和土壤水分含量;茶园覆盖稻草和种植豆科绿肥在夏秋干旱季增加土壤含水量,增加茶园害虫天敌数量,有效地控制害虫的生长和繁殖,改善茶园土壤结构,增加土壤有机质,提高N、P、K等养分的有效性。建立人工复合生态系统,可有效改善茶园生态环境,增加害虫天敌的种类和种群数量,结合农业和物理技术,做到少使用农药和化肥,实现亚热带丘山区茶园安全高效生产。
