摘要
从1982年第二次土壤普查、1997年的水稻田土壤养分复查及2008年的标准农田地力调查的三次结果可以发现,临安市稻田耕作层呈现了变浅的趋势。通过对历年来生产情况的研究,笔者对稻田耕作层变浅的原因进行了综合分析,得出长期浅耕或免耕是造成稻田耕作层变浅的主要原因,并针对性地提出了治理措施。
The data of the second general soil survey in 1982,the soil nutrients of rice fields review in1997 and the fertility of farmland survey in 2008 were analyzed,we find that the tillage layer of paddy fields showed a trend of shallowing in Lin＇an City.By studying production situation over the years,this article synthetically analyzed the shallowing reasons,drew a conclusion that the long-time shallow tillage and no-tillage is the major reason causing the shallowing of tillage layer of paddy fields,and several improvement countermeasures were proposed.
