Abstract
Field experiments were conducted to study the influence of ground cover rice production system (GCRPS) (plastic mulching, straw mulching and bare upland) on agronomic parameters of yield components and rice grain yield response compared with normal paddy field under controlled irrigation production condition. The results showed that rice tillers in GCRPS were earlier and more than that of normal paddy rice, plastic mulching better than that of straw mulching. To increase the basal seedling at transplanting or sawing could increase percentage of fertile tillers and decrease percentage of unfilled grains. Leaf area index (LAI) of rice in GCRPS decreased in the order of plastic mulching treatmentstraw mulching treatmentbare soil treatment among the treatments. The two-year results showed that the rice grain yields in GCRPS were slightly or significantly lower than that of normal paddy rice, but there was no statistical difference of above ground biomass between GCRPS and normal paddy, even if the biomass of plastic mulching treatment in GCRPS was higher than that of normal paddy. The results imply that there exists a great potential or possibility to receive high grain yield in GCRPS.
