Abstract:In order to investigate the effects of no tillage measurements on water holding capacity,grain yield,and production income,an experiment of different tillage ways was conducted in Yangling District,Shaanxi Province in 2007.Results showed that soil moisture was 1.2% higher in no tillage treatment compared with traditional tillage.Moreover,root length of corn in booting stage under no tillage was 26.6 m,71.6% more than that in traditional tillage.Finally,grain yield was 8 408 kg/hm2,which was increased by 11.3%,and production income was increased RMB 1991 yuan more than traditional tillage.The conclusion is that no tillage with straw mulching can efficiently increase soil moisture and evidently increase grain yield and production income.The sowing technology can be used in Guanzhong irrigation area and similar regions.
