试验研究了不同种植密度对薏苡农艺性状和产量的影响。结果表明:薏苡最佳密度为10 672株∕hm2(行距×窝距=60cm×50cm),小区(面积15m2)产量最高达到7.77kg,比其他3个处理高10.04%~21.24%,差异性显著。不同种植密度对薏苡农艺性状和产量都有不同程度的影响,薏苡分蘖、拔节、开花、成熟等生育进程随密度增大呈提前的趋势,薏苡分蘖期株高、成熟期株高、有效穗等农艺性状随密度增大而成增大趋势,成熟期茎围、单株有效茎蘖、千粒重、穗粒数随密度增大而呈减小趋势,薏苡产量随着密度的增大先增加后降低。
The effects of different planting densities on agronomic traits and yield of Coix lachrymalis were studied. The results showed that the optimal density of Coix lachryma - jobi was 10 672 plants / hm2 (row spacing × distance = 60cm × 50cm), and the yield of plot (15m2) reached 7.77kg, 10.04% ~ 21.24% higher than the other three treatments . Different planting density had different effects on the agronomic traits and yield of Coix lachryma - jobi. Advances in tillering, jointing, flowering and maturation of Coix lachrymahadaum showed an earlier trend with increasing density. Plant height, maturity height and effective spike The agronomic traits tended to increase with the increase of density. The stem circumference, the effective tiller, the weight of grains per plant and the number of grains per spike at the mature stage tended to decrease with the increase of density. The yield of Coix increased at first and then decreased with the increase of density .
