氮磷钾配施对砂姜黑土花生产量的影响

The Influence of N, P and K Fertilizers to Peanut Yield in the Black Sajong Soil

在砂姜黑土上 ,施肥可显著促进花生生长发育 ,提高荚果和籽仁产量 ;氮磷钾配施效果优于氮钾配施 ,氮钾配施又优于氮磷配施 ;氮磷钾配施较氮钾配施和氮磷配施荚果增产 15.7%、2 4 .8% ,籽仁增产 13.6 %、2 6 .5% ;较不施肥荚果增产 39.7% ,籽仁增产 4 3.2 %。实行氮磷钾平衡施肥是提高砂姜黑土花生产量的有效措施。

Fertilizer application can significantly improve the growth and development of peanut, and enhance the yield of the pod and seed. Matching application of N, P and K(NPK) is better than that of N and K(NK), and (NK) is better than the matching application of N and P(NP). NPK increased 15.7%, 24.8% and 39.7% in pod and 13.6%, 26.5% and 43.2% in seed, compared with NK, NP and CK (on fertilizer application), respectively. The balance fertilizer application of respectively, compared with N,P and K is an efficient measure of enhancing the peanut yield in the black sajong soil.
