本文以“吉农引快豆”矮生早菜豆为材料,采用二次通用旋转组合回归设计的方法系统地研究了矮生早菜豆采种量与密度和施肥的关系。通过田间小区试验数据,建立了种子产量函数模型,分析了种植密度、氮肥和磷肥施用量等主要农艺措施对种子产量的影响及其密度与硝酸铵施用量交互作用的效应关系,提出了矮生早菜豆采种田的密度和施肥最优化组合方案,为矮生早菜豆种子生产技术规范化提供了参考依据。
In this paper, we used “Jidongyitongdou” dwarf asparagus bean as raw material, and studied the relationship between the seed germination rate, the density and the fertilization using the method of quadratic common rotation combination regression. Based on field plot data, a seed yield function model was established, and the effects of planting density, nitrogen and phosphorus application rates on seed yield and the interaction between density and ammonium nitrate application were analyzed. Optimum combination of density and fertilizer application in early-harvesting beans provides the reference for standardizing the production technology of dwarf morninggreen beans.
