温棚内高湿是适宜病菌发生的重要条件,常规喷雾防治增加棚内湿度,防治效果受到影响,采用烟剂防治温棚蔬菜病虫弥补了喷雾之不足。为此,烟雾已成为温栅蔬菜病虫防治的主要剂型。单一的烟剂连续使用易产生抗性,研制新型高效系列烟剂,组装配套技术非常必要。我所自1985年以来一直从事烟剂研制和使用技术研究,已能向生产上提供7种烟剂,在番茄、黄瓜、芹菜、韭菜、豆角等探索出配套技术已示范100多万亩,1995年获唐山市科技进步二等奖。 1.新型高效系列烟剂防治番茄主要病虫配套
High humidity in the greenhouse is an important condition for the germs to occur. Conventional spray control increases the humidity in the greenhouse and the control effect is affected. Smoke and pesticide greenhouse vegetable pests and diseases make up for the lack of spray. To this end, smoke has become the main form of plant diseases and insect pests control. A single continuous use of tobacco smoke resistance, the development of new and efficient series of tobacco, assembly of supporting technology is necessary. Since 1985, I have been engaged in research and development on the development and use of tobacco smoke, and have been able to provide 7 kinds of smoke suppressants to our production. Over 1 million mu have been explored in tomato, cucumber, celery, leek, and bean fields. 1995 The city won the second prize of scientific and technological progress in Tangshan. 1. New and efficient series of tobacco control tomato pests and diseases supporting
