Effects of Soil-Covered Depth on Decomposition of Rice Straw in Winter Potato Field

XU Qiao-ling et al(College of Natural Resources and Environment,South China Agricultural University,Guangzhou,Guangdong 510642)  
[Objective] The research aimed to study the decomposition of rice straw in winter potato field.[Method] Rice straw were enclosed in nylon nets and returned to potato field to study the effects of soil-covered depth(0,5.0,7.5,10.0 cm) on decomposition course.[Result] Rice straw had the highest decomposition rate at soil-covered depth of 7.5 cm,and had the lowest rate at soil-covered depth of 0 cm.After decomposition for one potato growing season,the residual rate at soil-covered depth of 7.5 and 0 cm were 50% and 80%.C released at fast rate.During the course of decomposition,C/N ratio decreased due to the loss of total C.The residual rate of C was up to 76% at soil-covered depth of 0 cm,and those at soil-covered depth of 7.5,10.0 and 5.0 cm were up to 69.3%,70.8% and 72.5%,respectively.N conlent increased in 10 days before,then the rice straw could release N conlent to supply the potato growth.After one potato season,C nutrients release reached to 1/3 in total C.[Conclusion] The rice straw returned at beginning would kept N.The decaying process wasn't complete after one potato season.
