由于国家进行大规模经济建设,必须增产大量的粮食和工业原料,以适应需要。在农业生产过程中,克服缺苗断垅现象,已为政府及群众深切注意的问题。缺苗断垅主要的原因之一是由于地下害虫严重为害所致。这类害虫如蝼蛄、金针虫、蛴螬等,严重时竟至无法种下或须犁种数次,因此使作物受到影响而致减产,假如能够很好的把苗保住不致受地下害虫为害,产量是肯定可以增加的。现时已将届立春季节,行将进入农忙阶段,地下害虫经过蛰伏越冬,到春分后即出而为害,不论冬麦、春麦、杂量作物、油料作物、特用作物和烟苗、菜苗,果木幼苗,无一能幸免,所以必须及早进行防治的准备工作。这里我提出关于防治地下害虫的几个问题来和大家研究: Due to the large-scale economic construction of the country, a large amount of grain and industrial raw materials must be increased to meet the needs. In the process of agricultural production, overcoming the phenomenon of lack of seedlings and breaking off the ground has been a matter of deep concern to the government and the masses. One of the main reasons for the lack of seedlings is due to the serious damage caused by underground pests. Such pests such as stinkbugs, golden needleworms, scabies and so on, even in severe cases can not even planted or to be plowed several times, so the crop is affected and caused by the reduction of production, if the seedlings can be well protected from damage by underground pests, the output is Certainly can increase. Now that the Spring Festival will be set to enter the busy stage, the underground pests will be dormant through the winter, and the spring equinox will emerge and harm, regardless of winter wheat, spring wheat, miscellaneous crops, oil crops, special crops and tobacco, vegetable seedlings, fruit seedlings , No one can survive, so we must make preparations for prevention and treatment as soon as possible. Here I put forward a few questions on the prevention and control of underground pests to study with everyone:
