菜用型蚕豆稀植优化栽培研究

A Study on Sparse Planting Optimized Cultivation of Broad Bean (Vicia faba) in Vegetable

以蚕豆品种“云豆 32 4”为材料 ,探讨在云南昆明地区稀植情况下的蚕豆种植密度、单位面积尿素用量、硫酸钾肥用量与产量、植株生长状况的优化组合的关系。结果表明 :在土壤肥力水平较高的情况下 ,菜用型蚕豆最高产量的最佳密度为 7.40万株 /hm2 、最佳尿素施用量为61 .2 0kg/hm2 、最佳钾肥施用量为 1 2 1 .1 0kg/hm2 ,干籽粒产量最高可以达 3640 .0kg/hm2 。随着密度的增加单株产量减少、有效分枝数减少 ,呈规律性变化 ;单株的结荚数呈同样变化规律 ;单株籽粒数也同样减少 ;从百粒重分析 ,密度间的变化规律不明显 。

The optimized cultivation were conducted to study the realtionship among planting density,amount of application of urea and potassium sulphate on yield and growth of broad bean( Vicia faba ) with broad bean cultivar Yundou 324 in Sparse planting. The results showed that the optimized planting density of faba bean ( Vicia faba ) as vegetable is 7.4×10 4/ha, optimized amount of application of urea is 61.20 kg/ha, optimized amount of application of potassium sulphate is 121.10 kg/ha, and its seeds yield will get 3 640 kg/ha. Along with the increase of population densities, seeds yield and effective branch per plant will decrease. This is the regular change. And the number of pods and seed per plant present the same regular change too. The regular change between planting density and 100 seed weight is not so noticeable, and other treatments produce difference in seed yield and growth of broad bean.
