| 摘 要： | 为了解决江西省丘陵红壤常年种植"梅庄花生"技术落后问题,本试验研究丘陵红壤土质下施氮量与种植密度互作对"梅庄花生"生长发育及产量的影响,结果表明,在施氮135kg/hm2和种植密度40cm×20cm组合下,有利于果枝分化,结果枝所占比例最高,为85.6%,饱果率、百果重、出仁率等经济性状均较好,产量最高,达3909.8kg/hm2。

| Abstract: | In order to solve the problem of the backward perennial planting techniques of Meizhuang Peanut in Jiangxi hilly red soil,the effects of nitrogen（N）application and planting density interactions on the growth and yield of Meizhuang Peanut in hilly red soil were studied.Results showed that it increased the pod-bearing branches under the combination of the 135kg/hm2 N application and 40cm×20cm planting density,under which the pod-bearing branches attained the highest proportion up to 85.6%,and the plump pod percentage,weight per hundred pods,kernel percentage as well as other economic traits were all comparably higher.The highest yield was up to 3909.8kg/hm2 under the optimal combination of N application of 135kg/hm2 and planting density of 40cm×20cm in this study. |
