摘要: 采用三因素五水平通用旋转组合设计,对影响茉莉花产量的3个主要因素,即N(X1),P(X2),K(X3)进行大田试验,建立产量与N、P、K3因子的肥料试验模型,并采用降维法对所建立的数学模型进行分析,确定其最佳施肥量。试验结果表明,茉莉花的产量从整体上来看与N成负相关,与P、K成正相关,作用的大小顺序为K > P > N。最佳施肥量为氮肥(N)132.4~197.6kg/hm2,磷肥(P2O5)166.6~197.4kg/hm2,钾肥(K2O)126.8~155.3kg/hm2

Abstract: By using the quadratic rotational combination besign in purple paddy field, studies were done on the effect of three factors(N, P, K).N, P, K fertilizer was a major factor which affected the yield of jasmine.The model of fertilizer effect was established by reducing dimensional analysis.The results indicate that:the yield of jasmine has a negative correlation with supply of nitrate and a positive correlation with supply of P, K from overall.The order of N, P, K influence on the yield of jasmine is K > P > N.The optimal combination of N, P, K is 132.4~197.6 kg/hm2 N, 166.6~197.4 kg/hm2 P2O5, 126.8~197.4 kg/hm2 K2O.

Key words: jasmine, balance fertilization, quadratic rotational combination design, yield
