不同群体密度对绿豆农艺性状和产量的影响研究

该文探讨了不同种植密度对直立型绿豆品种的经济性状、产量构成因素以及产量的影响。结果表明:种植密度越大,绿豆的株高越高,单株荚数随着密度的增加呈下降趋势,主茎节数、荚长、百粒重和单荚粒数则没有明显变化。不同的种植密度对绿豆产量的影响呈现先增后减的变化趋势,在一定的栽培条件下,绿豆在适宜的种植密度条件下才能获得较高的产量,同绿1号绿豆品种高产栽培的适宜密度是18万株/hm2。

Effects of Different Population Densities on Yield and Agronomic Characteristics of Mung Bean

This paper discussed the different planting density on the upright mung bean varieties of eco-nomic traits,yield components and yield. The results showed that planting density,the greater the mung bean of the higher plant job,number of pods per plant increased with the increase of density is on the de-cline,number of main stem section,pod length,single pod hundred kernel weight and number of grains is no obvious change. The influence of different planting density on mung bean production has the change trend of increase after decreases first,under the condition of certain culture,mung bean under the condi-tion of suitable planting density can get high yields,with Tonglv no 1 mung bean varieties of high yield cultivation of appropriate density is 180000 plants/hm2.
