我社地处平原,土杂肥来源少,田土大多是浅脚沙土,历年虫害成灾,是个有名的老虫区。为了解决这些问题,我们采取了蹲点搞试验示范,以点带面的做法。例如:为了改良土壤,推广稻秆还田,针对我杜夏收稻秆没有还田习惯的情况,我们于一九七四年在双洞大队第八队蹲点时,做了稻秆还田与不还田的对比试验,并组织全社各生产队长到现场从事试验活动。结果,稻秆还田的泥土松软,亩产比不还田的增加57.8斤。目 I clubs are located in plain, Tuza Fei less source, most of the soil is shallow sand, pest disaster over the years, is a famous insect zone. In order to solve these problems, we have taken a series of experiments and demonstrations in order to make a point. For example, in order to improve the soil and promote the return of rice straw to the field, in response to the situation in which I did not return rice straw to Dusia, we made rice straw in the fourth team of the Double Hole Brigade in 1974 Returning to the field of comparative tests, and organize the production of the captain of the whole community to the scene to engage in experimental activities. As a result, the soil of rice straw returning to fields was soft, increasing 57.8 kg more than returning to non-return. Head
