- W2356164872 abstract "In order to investigate the effects of different sulphur fertilizers on rice and the recycling and balance of sulphur in rice-rice agro-ecosystem,seven treatments with different sulphur fertilizers were applied in a rice-rice cropping field with randomized block design,which included no sulphur(CK),ammonium sulphate(AS),single superphosphate(SSP),elemental S(ES),gypsum(GYP),50% S from gypsum and 50% from elemental sulphur(50% GYP + 50% ES),70% S from gypsum and 30% from elemental sulphur(70% GYP + 30% ES).The results indicated that the effects of various sulphur fertilizers on grain yield of early rice were very significant with increasing rate 9.1%～10.3%.Applying sulphur fertilizers in early rice could increase rice dry straw yield significantly with increasing rate 5.3%～11.6%,as well as the effective panicle per hectare.The plant height and panicle length were not affected obviously by applying various sulphur fertilizers,but it increased seed setting rate and 1000-grain weight.Application of sulphur fertilizers could not increase sulphur content in the straw and grain for both early and late rice obviously,but it increased the sulphur uptake for early rice significantly.The benefits from the application of sulphur fertilizers were very good,and the net income of ES treatment was the highest with 1882.6 RMB yuan/ha.When 30kg/ha S per year was applied to a rice-rice cropping system in the areas of Guangxi,a positive sulphur balance could be remained in the soil while a negative sulphur balance was observed for the CK.Use of sulphur containing fertilizers seems a good strategy for rice production in Guangxi." @default.
