摘要
研究了新乡市无机肥的增产效应及培肥地力的作用,探明了无机氮磷钾的直接增产与互作增产效应,明确了在高产栽培中氮磷钾兼施、以磷增氮的作用,展望了土壤养分平衡状况对农业生产可持续发展的影响。
The effect of inorganic fertilizers on the increase of production and the fertility of soil in Xinxiang City were studied. The direct effect of inorganic fertilizer nitrogen, phosphorous and potassium on production and their co-effects on production increase were investigated. It was made clear that balanced application of nitrogen, phosphorous and potassium, with phosphorous application in promoting the absorption of nitrogen in the high production plantation.
