摘　　要：本试验采用起垄地膜覆盖栽培方法,以花生品种山花9号为材料,研究了不同控释氮肥配比对花生蔗糖积累和产量的影响。结果表明,控释氮肥较普通氮肥在结荚后期叶面积指数高、叶片SPS活性和蔗糖含量高,利于提高百果重和饱果率,显著提高了荚果产量。掺混氮肥处理花生在苗期和花针期叶面积指数、SPS活性和蔗糖含量均较高,与普通氮肥处理无显著差异;生长后期不脱肥早衰,利于提高百果重和饱果率,荚果增产更明显。Field experiment was conducted to examine the effects of different nitrogen fertilizers on yield and sucrose synthesis of leaves in peanut Shanhua9 with ridge plastic film and mulching. The results showed that the application of controlled-release nitrogen fertilizer could significantly increase the LAI, SPS activity and sucrose content of peanut leaves than common nitrogen fertilizer and it was advantage at improving 100 pods weight, the rate of full pods and the yield of peanut. The mixed ap- plication of common nitrogen fertilizer and controlled-release nitrogen fertilizer had the higher LAI and SPS activity and sucrose content of peanut leaves at YSP and FPP, and had no difference to the com- mon nitrogen fertilizer. Because there was no premature in the mixed treatment, the rate of full pods and 100 pods weight was enhanced, and the pod yield increase was more obvious.
