Study on the Effect of No-tillage Mulch on Soil Characteristics of Rice Fields and Crop Yield in Long-Term Located Field Experiment

Chen Kai-lu

Abstract

To study the effect of no-tillage mulch on soil characteristics and crop yield in wheat-rice rotation system,a long-term located field experiment had been put into practice in 2008.In this experiment the soil nutrient content,soil water content,soil temperature and soil bulk density had been determined regularly.The results show that no-tillage mulch can reduce soil bulk density,improve soil nutrient content,regulate soil temperature,enhance soil water content and increase crop yield.
