稻田实行免耕(灭茬)可以迅速改善土体爽水性,防治青泥化,为苏南平田地区继续发展各种多熟制创造良好的土壤环境.但一些研究报道大都侧重土壤的形态变化及物理结构的描述,而对引起变化的主导因素之一的水分动态则未有系统的研究.本研究试图通过稻田土壤剖面水分动态的观察,比较常规耕作(干耕水旋)与免耕措施对黄泥土防渍促爽的效应,为研究改善耕作技术和水浆管理提供依据.
The no-tillage (stubble removal) in paddy fields can rapidly improve the soil coolness, prevent and control the cementation, and create a good soil environment for the continuous development of various multi-cooked systems in the Pingtan area of southern Jiangsu Province. However, some researches have mostly focused on the morphological changes and physical Structure, and the water dynamics, one of the leading factors causing the change, has not been studied systematically.This study attempts to compare the effects of conventional tillage (dry-farming water spin) and no-tillage measures on yellow Soil anti-dumping Shuangshuang effect for the study to improve farming techniques and water slurry management provide the basis.
