综合笔者与其他研究者考察结果、文章对西藏麦类及其它粮食作物、油菜及豆类.蔬菜、果树、及牧草等主要作物之72种主要病虫草害的发生与为害情况进行了分析,探讨了西藏自然因子(包括温度、湿度、天敌),人为因子(包括耕作制度,防治实践)与病虫草害发生发展的关系。文章对西藏主要作物病虫草害5~10年内发生趋势进行了分析和预测,并提出了主要的控制策略。关于西藏主要作物病虫草害发生情况,先后有不少研究者进行了考察。包括王林瑶(1965)、王荫长等(1979),何潭等(1985)、胡胜昌等(私入通迅),孔常兴等(1985)、王保海等(未发表)、王宗华等(1985、1986)的一系列工作,并且得到基本上一致的结果和看法,然而.各作者对其发生发展的趋势却很少分析,中长期发展趋势预测更是没有。本文将对西藏主要病虫草害的发生及其发展的影响因子进行分析,作其5~10年内发展趋势预测.并提出主要控制策略.
Based on the findings of the author and other researchers, the paper analyzes the occurrence and the damage of 72 major pests and diseases of wheat and other food crops, rape and beans, vegetables, fruit trees and grasses in Tibet. The relationship between natural factors (including temperature, humidity and natural enemies), human factors (including tillage system, prevention and control practices) and the occurrence, development and development of pests, weeds and diseases in Tibet were discussed. The paper analyzed and predicted the occurrence trend of major crop pests and diseases in Tibet within 5 ~ 10 years and put forward the main control strategies. About the occurrence of the main crop diseases, pests and weeds in Tibet, many researchers have successively inspected. Including Wang Linyao (1965), Wang Yinchang (1979), He Tan et al. (1985), Hu Shengchang et al. (Private communication), Kong Changxing et al. (1985), Wang Baohai et al. (Unpublished), Wang Zonghua et al. Series of work, and get basically the same results and opinions, however, the trend of development of each author is seldom analyzed, the prediction of the long-term development trend is even worse. This article will analyze the main factors affecting the occurrence and development of pests, diseases and pests in Tibet and forecast the development trend in 5 to 10 years and put forward the main control strategies.
