摘　　要：大田条件下,以花生品种仲恺花1号为材料,研究控释肥不同配比对丘陵红壤花生产量及主要农艺性状的影响。结果表明:相比单施普通氮肥,施用控释肥能显著增加产量,并且配施2/3控释肥和单施控释肥达极显著水平;配施2/3控释肥和单施控释肥能显著增加分枝数,极显著增加主茎绿叶片数,还能显著提高单株果重和单株饱果数;控释肥配施在结荚期和收获期冠层NDVI指数高。在控释肥的配施比在0.78时,产量最高。Field trial was carried out to discover the effects of different controlled-release ers ratio on yield and main agronomic traits of the peanut with the variety of ＂Zhongkaihual＂ red soil. The results showed that： compared to traditional nitrogen fertilizer utilization, the tion of controlled-release fertilizer could significantly increase the yield of peanut, and 2/3 an application of controlled-release fertilizer reached fertiliz- on hilly applica- d single extremely significant difference. 2/3 and single ap- plication of controlled-release fertilizer increased the number of lateral branch, green leaves in stem, pod yield per plant and plump-pod number per plant significantly. The application of controlled-re- lease fertilizer could increase canopy NDVI index in pod-setting and best effect on yield of peanut was the treatment of 0.78 application ratio o maturity stages of peanut. The f controlled-release fertilizer.
