【摘要】 以黔西南州普遍种植的白壳薏苡(Coix lachryrma-jobi L.)为材料,通过随机区组设计,探讨不同种植密度对薏苡产量及构成因子的影响。结果表明,不同窝行距对株高、株穗数、株粒数、百粒重有明显影响,差异达极显著或显著水平,对窝株数影响不大;不同下种量对株高、株粒数、百粒重、窝株数有影响,差异达极显著或显著水平,对株穗数影响不大。更多还原

【Abstract】 Taking white shell Coix commonly grown in Qianxi Prefecture as material,the effects of different planting densities on yield and yield component factors of Coix were explored by randomized block design. Results showed that the different fossa and row spacing on yield constitute factors including plant height, panicle number, grain number per plant, 100-grain weight had significant influence, however they had little impact on the nest number;Different seeding amount on the yield component factors including plant height, grain number, 100-seed weight, number of nest had very significant influence, yet had little impact on the number of spike per plant.更多还原
