| 摘 要： | 通过油菜小区试验研究,结果表明:不同施肥量,不同N、P、K配比,均有不同的化肥利用率;土壤养分测定值与目标产量、空白田产量均正相关;土壤养分测定值与化肥利用率负相关;利用测土施肥公式,建立了N、P、K化肥施用量与土壤养分测定值的函数关系,能在产前提出合理的施肥计划。

| Abstract: | Results of a rape plot experiment in Southeast Guizhou show that different fertilizer application rates and different NPK ratios resulted in different fertilizer recovery rates. Measured values of soil nutrients were positively related to target yield and yield in CK, but negatively to fertilizer recovery rate. Based on the formula of soil testing and fertilizer recommendation, functional relations between NPK application rate and measured valuea of soil nutrients were established, enabling reasonable fertilizer recommendation prior to sowing. |
