摘要
采用“3414”不完全方案试验,研究临河区不同产量下青椒的养分肥效和增产指数,利用相对产量和土壤测试值的相关关系,建立青椒氮、磷、钾施肥指标体系,确定合理的施肥量和施肥配比,以指导临河区青椒生产科学施肥。结果表明,临河区不同产量下青椒的养分肥效为氮磷钾肥的足量配合施用对青椒产量的影响最大,氮磷钾肥的综合效应为46.5%,说明足量氮磷钾肥配合施用,才能发挥肥料的最大效应;增产指数以钾肥最大,为99.6 kg/kg,肥料配比为8-27-10。
With“3414”incomplete scheme,the nutrient fertilizer efficiency and yields increase index of green pepper under different yields in Linhe were studied.Nitrogen,phosphorus and potassium fertilization index system for green pepper by the correlation between relative yield and soil test value was established,and the reasonable fertilization amount and fertilization ratio were determinated in order to guide scientific fertilization of green pepper production in Linhe.The test showed that the greatest impact on the yield of green pepper was adequate combined application of nitrogen,phosphorus and potassium fertilizers,the comprehensive effect of NPK fertilizer was 46.5%.It showed that the sufficiently combined application of nitrogen,phosphorus and potassium could exert the maximum effect of fertilizer,the maximum yield index of potassium fertilizer was 99.6 kg/kg,the fertilizer ratio was 8-27-10.
