为掌握芸豆品种群体结构动态变化,构建芸豆施肥模型,采用密度试验和“3414”肥料效应试验。结果表明:不同芸豆品种在不同密度条件下,其经济性状和产量表现不同。小粒型品种表现出随密度的增加产量持续增加,大粒型品种随密度的增加产量先增加后降低。试验品种大红芸豆‘YD混1’的最佳种植密度为9.75万株/hm2;氮、钾肥对芸豆产量的影响表现为随使用量的增加先增加后降低的趋势,磷肥对芸豆产量的影响表现为随施用量的增加而增加。芸豆的推荐施肥量为氮肥48.93kg/hm2,磷肥45kg/hm2,钾肥55.28kg/hm2。芸豆栽培中合理的群体结构和最佳的施肥量及其配比是提高芸豆产量的重要因素。
In order to grasp the dynamic changes of the population structure of kidney bean varieties, the kidney bean fertilization model was constructed, and the density test and the “3414” fertilizer effect test were used. The results showed that the economic traits and yield of different kidney bean varieties under different densities were different. Small grain varieties showed an increasing yield with increasing density, large grain varieties with increasing density, yield increased first and then decreased. The optimum planting densities of ’YD mixed 1’ were 97500 plants / hm2. The effect of nitrogen and potassium fertilizer on the yield of kidney bean was firstly increased and then decreased with the increase of the amount of application. The effect of phosphorus fertilizer on the yield of kidney bean With increasing the amount of increase. Kidney beans recommended fertilizer amount of nitrogen fertilizer 48.93kg / hm2, phosphate fertilizer 45kg / hm2, potassium 55.28kg / hm2. The proper population structure and the optimal amount of fertilizer and its ratio in kidney bean cultivation are the important factors to increase the yield of kidney bean.
