摘要: 通过田间试验,水稻的地力产量、目标产量均与土壤养分测定值正相关;化肥利用率与土壤养分测定值负相关;逐一分析养分平衡法施肥公式中各子项与土壤养分测定值的数量关系.建立推荐施N、P2O5、K2O量分别与土壤速效氮、磷、钾的一一对应函数关系。

Abstract: Passing the field experiment studies,the land productivity output,object output of the paddy rice all measureless with soil nutrient the value positive related;turn the fatty utilization measures with soil nutrient the value negative related;Analyze one by one nutrient balance articles fertilization formula each trichinae of inside paragraph measures with soil nutrient the worth quantity relates to,creating to recommend placement N ,P2O5,K2O quantity difference and soil readily available nitrogen, phosphorus,a couple of the potassium should function relation.
