摘要
本文研究应用冬季砍杂垦复、笋期药饵诱杀和自制烟剂熏杀等关键技术综合防治把竹主要害虫竹笋夜蛾、一字竹象、小竹象和江苏泉蝇 ,两年来共示范和推广防治 2 74hm2 ,防效达92 %～ 99%。防治区新竹平均眉径比对照提高 1 34～ 2 68cm ,新竹平均高比对照提高 2 45～ 2 91m。经核算 ,防治区比对照区每hm2 均增收 2 70 0元 ,增收总额为 73 98万元 ,新增利税为 69 0 4 8万元 ,投入产出比为 1∶1 5 ,经济和社会效益十分显著。
This article has studied integrated control of “bundle” bamboo (i.e usually bundled after harvest and with outer breast diameter 1～8 cm)'s main pests- Oligia Vulgaris (Butler), Otidognathus davidis Fairmaire, Otidognathus nigripictus Fabricius and Pegomyia Kiangsuensis Fan by use of such key techniques as cutting weeds and shrubs and reclaiming in winter, luring with medical bait during period of bamboo shooting, fumigating with self-made smoke agent. In the recent two years, we totally demonstrated and popularized this technique over 274 hm 2 for controlling the pests. Its control efficiency reaches 92%～99% in the control region. The average breast diameter of the new bamboo was increased by 1 34～2 68 cm and average height of new bamboo was 2 45～2 91 m higher than the control's. Through financial calculation, we found that, compared with control region, 2 700 Yuan per hm 2 of added income and 739.8 thousand Yuan of total added income are from the studied region. The newly-added interests and taxes is 690.48 thousand Yuan and the ratio of input-output is 1∶15 and the economic and social effect is quite evident.
