渭北旱原农果作物主要病虫治理技术规范

Technical Specification of Managing Main Crop Pests on the Weihei Rainfed Highland

根据1986～1989年在下丁家村的田间试验及防治示范结果,提出了适用于谓北旱原的农果作物主要病虫预测预报标准和防治技术规范。数年的在用实践表明,病虫为害保产价值5万多元,节约农药费用5000多元。该技术体系可进一步在渭北旱原其他地区推广使用。

Based on the results of field experiments and management demonstrationsbetween the years of 1986-1989 in Xiadingjia village,Qianxian county,thispaper presehts a technical specification of managing crop pests(i.e.grain cropsand fruit crops)and a prediction system of the pests,which are adaptable tothe Weibei Rainfed Highland.It is indicated through many years'applicationof this specification that economic returns achieved from crop protection reachmore than 50,000 yuan,and that the insecticide cost saved reaches 5,000yuan.This technical system can be extended and used in other regions over theWeibei Rainfed Highland.
