摘要
为解决生产上存在的盲目和过度施肥现象,提高肥料利用率,利用"3414"试验设计研究了粤油26号花生施用氮、磷、钾在黄泥土中的效应,结果表明,正安县黄泥土最佳施肥量为N 225.0 kg/hm2,P2O5114 kg/hm2和K2O 133.2 kg/hm2;最佳产量为5334 kg/hm2。尿素、普钙和氯化钾的利用率分别为86.4%、3.6%和27.2%。
In order to overcome the phenomena of blind and excessive fertilization,and enhance fertilizer use efficiency in the production of peanut,the effect of applying nitrogen,phosphorus and potassium fertilizer on peanut variety ＂Yueyou No.26＂ in the yellow soil of Zheng＇an county was studied by using ＂3414＂ experimental design.The results showed that the optimum application rates of nitrogen（N）,phosphate（P2O5） and potassium（K2O） were 225.0,114.0 and 133.2 kg/hm2,respectively,and it got the highest yield 5334 kg/hm2.The use ratios of urea,superphosphate and potassium chloride were 86.4%,3.6% and 27.2%,respectively.
