【摘要】 应用二次回归通用旋转组合设计的试验方法，探讨了蚕豆高产高效优质栽培中的主要措施（施氮磷量，种植密度）与构成群体生产力性状的主次关系，和双因素互作对产量、品质及土壤肥力的效应。根据回归数学模型求得的亩产高于３００ｋｇ、亩纯收益大于１００元的农艺组合区间是：亩播密度１２４２０～１４７２０株，亩施Ｎ３．８８～６．００ｋｇ．Ｐ＿２Ｏ＿５６．９６～１０．３４ｋｇ；措施中心组合是：密度１３５７０株／亩，施Ｎ４．９４ｋｇ／亩，Ｐ＿２Ｏ＿５８．６４ｋｇ／亩，Ｎ：Ｐ２＿Ｏ＿５约为１：１．７５。更多还原

【Abstract】 The experiment method of binary regression universal integrated designwas used to discuss the major measures(the amount of N/P application,and plantingdensity),the first and secondary relationships of productivity traits of components of plant population and the effect of interaction of double factors upon yield quality and soilfertility in high-yielding and high-efficiency cultivation of broad beans.Per mu yield ob-tained by mathematical regression niodel was over 300kg and the agro-integrated sec-tions with 100 Yuan/mu over were that plant density per mu was 12 420～14 720plants;and that N/P application is 3.88～6.00kg of N/mu and 6.96～10.34kg of P/mu;and also that the centre integration of the measure was that plant density was13 570 plants/mu;N application was 4.94kg/mu;P2O5 application was 8.64kg/mu;andthe ratio between N and P2O5 was 1.75.更多还原
