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。
By using quadratic regression general rotation combination design method, the main measures (nitrogen and phosphorus, planting density) and the primary and secondary relationships of population productive traits in high yielding and high quality cultivars of Vicia faba were discussed, and the effects of two factors on the yield and quality And the effect of soil fertility. According to the mathematical model of regression, the agronomic combination interval of more than 300kg of mu per mu and net profit of more than 100 yuan per acre was: 12420 ~ 14720 mu per mu, and N 3.88 ~ 6.00kg per acre. P_2O_56.96 ~ 10.34kg. The center of combination is 13570 plants / mu, N4.94kg / mu, P_2O_58.64kg / mu, and N: P2_O_5 about 1: 1.75.
