摘要
在田间试验条件下,研究了不同配比的氮钙肥对红衣米花生农艺性状及产量的影响。结果表明:施用钙肥抑制红衣米花生的主茎高、侧枝长和分枝数;施用氮、钙肥能增加红衣米花生的单株饱果数和出仁率;施用钙肥降低红衣米花生的瘪果数,对百果重的影响较小。在本试验条件下,施用氮330kg/hm2和钙120kg/hm2,红衣米花生的产量最大,经济效益最好。
A field experiment was executed to study the effect of application of N and Ca fertilizer on agronomic characters and yield of red-skin peanut.The results showed that application of Ca fertilizer could significantly prevent the main stem height,lateral branch length and branch number of redskin peanut.Application of N and Ca could increase plump pods percentage and kernels percentage of red-skin peanut.Ca could reduce empty-pods and had little effect on the 100-pods weight.Therefore,the best effect on yield of red-skin peanut was the treatment of N 330kg/hm2 and Ca 120kg/hm2 in this study.
