摘要
通过测土配方施肥对丰源优272的试验数据分析得出,N、P、K对其经济性状都有不同程度的影响,以P增产效应较大,N相对略低,K次之。最佳施肥量为46%尿素298.5 kghm2、12%过磷酸钙312.0 kghm2、60%氯化钾82.5 kghm2,其产量为7 707.0 kghm2,为衡东县水稻生产提供了测土配方施肥的技术依据。
Through analysis of measuring soil fertilizer of Fengyuanyou 272,test data showed that N,P and K on its economic characters had different degrees of influence,and P production effect was largest,N relatively slightly,K followed. Best fertilizer rate was 46% urea 298. 5 kghm2,12% calcium superphosphate 312. 0 kghm2,60% potassium chloride 82. 5 kghm2,its output was 7707. 0 kghm2. It provided rice production technical basis for measured soil fertilizer in Hengdong county.
