冬耕提高土壤肥力的作用,已有一定理论基础,但在水田中冬耕对土壤理化性质及水稻生育的影响,还很少看到具体的报导。为此,我们在浙江余姚群众原有稻田冬耕习惯的双季稻地区,进行了一些有关的研究工作,希望积累部分具体资料,为进一步研究稻田耕作法提供依据与参考。 Winter plowing has a certain theoretical basis for improving soil fertility. However, it is seldom seen in concrete reports that winter plowing affects soil physical and chemical properties and rice growth in paddy fields. For this reason, we carried out some relevant research work in the double cropping paddy area where the original winter paddy habit of rice paddy was used by the masses in Yuyao, Zhejiang Province. We hope to accumulate some specific information and provide the basis and reference for further research on the paddy field farming method.
