我乡位于洛阳市郊西南部,灌溉条件较好,适合小麦红吸浆虫繁衍。1985年因吸浆虫危害曾造成小麦严重减产。经几年的综合防治,目前基本控制了危害。采取的措施是:1、合理轮作倒茬:在吸浆虫的重发区,将常年种植小麦、玉米的地块,调茬种蔬菜或其它经济作物,一般隔4年以后再种小麦。这期间让吸浆虫失去寄主,自然死亡。在可种水稻的地块,实行小麦、水稻轮作,能有效地防治吸浆虫。据在杨庄淘土调查,第一年种水稻,消灭吸浆虫79.9%,第二年种水稻后,淘土和网捕成虫,均未发现吸浆虫。此法的前提是稻田内必须长期保持有水层,早稻田和湿润稻田的防治效果不好。2、麦收后浅锄灭茬暴晒:据我们观察,吸浆虫多在0—3厘米的土层内(虫量占91.2%),
I Township is located in the southwest suburbs of Luoyang, irrigation conditions are good, suitable for the proliferation of wheat Midge. In 1985, the harm caused by midge had caused a serious yield reduction of wheat. After several years of comprehensive prevention and control, the current basic control of the hazard. Measures taken are: 1, a reasonable rotation cropping: in the resuscitation area of midge, the perennial planting of wheat, corn plots, cropping vegetables or other cash crops, generally 4 years later wheat. During this period so that the Midge lost host, natural death. Can be planted in the plots of rice, the implementation of wheat, rice rotation, can effectively prevent midge insects. According to the investigation of the Taoist village in Yangzhuang, the first year was planting rice and 79.9% of inhaling plasmids were eliminated. After the second year of planting rice, Amoebae were not found in Amoy and netted adults. The premise of this method is that the water layer must be maintained in the paddy field for long periods of time, and the control effect in the early paddy fields and wet paddy fields is not good. 2, after the wheat harvest shallow hoe stubble exposure: According to our observation, toad inhalation more in 0-3 cm soil layer (insect volume accounted for 91.2%),
