Effects of Controlled-release Fertilizer on Growth and Yield of Regeneration Rice
In this paper,'Weiliangyou 8612'was used as the experimental material,and five different treatments were set up to study the effects of controlled-release fertilizer on the growth and yield of regeneration rice.The results showed that the application of controlled-release fertilizer did not lead to the reduction of rice yield when the conventional fertilization was reduced by 10%-20%.Considering the rice yield and planting economic benefits,it is suggested that in the process of regeneration rice planting in Qianshan County,replacing conventional chemical fertilizers with controlled-release fertilizers and reducing the amount of nutrients by 20%can achieve cost-saving,efficiency-enhancing and environmental protection benefits.
