摘要
菜豆是世界上最重要的谷物豆类之一,是全球栽培面积最大的食用豆类,也是传统的粮食作物。为明确不同栽培密度和氮肥施用量对菜豆生长以及产量的影响,采用裂区试验设计,以红花白荚菜豆品种为材料,在三种不同的栽培密度水平下,研究了4种不同氮肥施用量下的菜豆在分枝期、开花期、结荚期、成熟期4个时期的茎粗、叶长、叶宽、株高、叶绿素相对含量、菜豆单株结荚数和单果质量。结果表明,M1N1(行距60 cm、株距20 cm、施用尿素45 g·m^(-2))处理下菜豆株高、单果质量及单株结荚数均为最高,生长及产量表现良好,可作为菜豆生产的最优配置在生产中推广。
Kidney bean(Phaseolus vulgaris L.)is one of the most important cereals in the world,the largest cultivated area of food beans in the world,and is also a traditional food crop.In order to determine the effects of different cultivation densities and nitrogen application rates on the growth and yield of kidney bean,we adopted a splitplot experiment design,and Honghuabaijia kidney bean was used as experimental material.Stem diameter,leaf length,leaf width,plant height,chlorophyll content,pod number per plant and fruit quality of bean were studied under four different nitrogen fertilizer application rates at branching stage,flowering stage,podding stage and maturity stage.The results showed that M1N1 treatment had the highest plant height,pod weight and pod number,and the growth and yield were good,which could be used as the optimal configuration for bean production.
