不同移栽密度对诸葛菜生长和籽粒产量的影响

探究不同移栽密度对诸葛菜的生长和籽粒产量的影响,确定适宜的移栽密度,为沿淮地区诸葛菜高产栽培提供参考。采用单因素随机区组试验,设置五种不同的移栽密度(11.68万株/hm~2、14万株/hm~2、16.33万株/hm~2、18.66万株/hm~2、21万株/hm~2)的处理测定诸葛菜的生长指标和产量指标。随着移栽密度的增加,诸葛菜的株高、无效分枝、主花序有效长度、主花序有效角果数、秸秆干重、每角果粒数及产量均呈现先增加再降低的趋势,而根颈粗、千粒重、二次分枝数等呈现下降趋势。在江淮地区诸葛菜种植密度为16.33万株/hm~2时,产量达到最高为674.09 kg/hm~2。

Effects of Different Transplanting Density on Growth and Yield of Orychophragmus Violaceus

It is to explore the effects of different transplanting density of Orychophragmus violaceus growth and yield,and to determine the optimum transplanting density and high-yield cultivation of Orychophragmus viola-ceus areas along the Huaihe River. By field randomized block experimental design with five density(11. 68 thou-sand plants / hm2 ,140000 plants / hm2 ,16. 33 million / hm2 ,1. 866 million / hm2 ,21 million trees / hm2 ) and three repeated method,determination of Orychophragmus violaceus indicators of growth and yield index is done. With the increase of planting density,the plant height of Orychophragmus violaceus,invalid branch,main inflorescence effective length,effective pods of main inflorescence number,dry weight of straw,seed number and yield are presented first increase and then decrease trend,and root collar diameter,1000 grain weight,sec-ondary branches showed declining trends are searched. Orychragmus violaceus in Jianghuai area with planting density of 163300 plants /hm2 production reached up to 674. 09kg/hm2 .
