摘要
在磷钾钙等营养充分补足的条件下 ,随着N素用量的增加 ,花生荚果产量逐步提高 ,但当N素用量增加到 171.0kg/hm2 后 ,花生产量又开始回落 ,表明本地区花生高产栽培条件下 ,N素用量须适当增加 ,但不宜过量 ,以促进花生高产稳产。
Under the condition of sufficient P. K. Ca in the Tongyang area, nitrogen fertilizer is, the more the yield becomes. However, it can be restrained by over the amount of 171.0kg per hm 2, when the amount of nitrogen fertilizer is higher, the yield of peanut is lower. Under the condition of high yield cultivation, in this locality, yield of peanut is increased by using suitable nitrogen fertilizer. For this reason, its higher and stable yield is improved.
