摘要
Abstract
In order to optimize the suitable amount of nitrogen and phosphorous fertilizer of maize ,the effects of nitrogen and phosphorous fertilizer on the yield of maize were studied by field experiments .The results showed that the effects of nitrogen and phosphorous fertilizer amount on maize yield reached a significant level .The a-mounts of nitrogen and phosphorous fertilizer were 530 .56 and 105 .45 kg·hm-2 respectively when yield of maize was the highest .关键词
