摘要
为了明确"永丰年"牌调理剂在水稻上施用效果,采用随机区组设计在湖南省祁东县红壤稻田进行了试验研究。结果表明:在红壤地区稻田上施用"永丰年"牌调理剂肥料使水稻增产7.1%,使氮肥的利用率提高10%、磷肥提高6.2%、钾肥利用率提高2.4%;调理剂农学效率为0.9kg/kg,调理剂用量以40kg/hm^2为佳。施用调理剂同时可以提高土壤中有机质和土壤其他养分,对土壤具有一定培肥作用。
In order to clarify the effects of ＂Yongfengnian＂ brand of conditioner applied on rice, this field experiment was carried out in paddy soil with randomized design derived from red earth in Qidong county, Hunan province. The results indicated that the ＂Yong - feng - nian＂ brand of conditioner fertilizer applied on rice could increased the rice yield more than 7.1%, and increased the nitrogen, phosphorus and potassium fertilizer utilization by 10%, 6.2% and 2.4% , respectively. The agronomic efficiency of the conditioner was 0.9 kg/kg, and the application rates of conditioner about 40 kg/667m2was preferred. The conditioner could increase the organic matter of soil and others nutrients, had a certain effect on paddy soil fertility.
