近年来,我县实行稻草还田的面积每年达13万多亩,占双季稻草种植面积的95%以上。稻草还田具有就地取材、肥源广、成本低、省劳力等优点。对解决晚稻田有机肥源不足,促进全年增产有着重要的作用。为了研究稻草还田对培育土壤肥力的作用,我们选择黄底灰泥田、黄泥田进行连续3年(1983—1985)田间试验。本文是试验的总结。
In recent years, the implementation of straw in our county reached an area of more than 130,000 mu each year, accounting for more than 95% of the double-cropped straw planting area. Straw has the advantages of local availability, wide sources of fertilizer, low cost, labor-saving and so on. It has an important role in solving the problem of lack of organic fertilizers in late paddy fields and promoting the annual yield increase. In order to study the effect of straw returning on soil fertility, we selected yellow clay and yellow soil for three consecutive years (1983-1985) field experiment. This article is a summary of the experiment.
