七十年代以来,苏州地区稻田土壤。出现渍害较重、物理性质不良,这与复种指数提高后,耕耙次数多,作用于土壤的机械强度大,特别是带水耖耙,有很大的关系。针对这些问题,从1980年起,我们对稻麦轮作的水稻土,进行了免耕法种稻的研究,现将两年来麦—稻—稻三熟制中麦茬免耕种植前季稻的结果简介如下: Since the seventies, Suzhou area paddy soil. Heavy stains appear, poor physical properties, which is related to the increase of multiple cropping index, the number of harrows and the large mechanical strength acting on the soil, especially the water rake. In response to these problems, from 1980 onwards, we paddy rice and wheat rotation conducted no-tillage method of rice research, now two years of wheat-rice-rice three-cropping no-till planted before planting rice results Brief introduction is as follows:
