不同种植密度和种植方式对红缨子漂浮苗农艺性状及产量的影响

目的]探索珍酒集团指定品种红缨子的标准化栽培技术,摸索出适合红缨子的最佳种植方式和密度。方法]开展2、3株种植方式的9万、12万、15万株/hm23个密度栽培对比试验。结果]随着栽培密度的增加,株高、穗长、着壳率、千粒重都降低,其中以9万株/hm2处理的经济性状较好;产量以12万株/hm2处理的最高,在2株栽培方式中比9万、15万株/hm2处理分别增产400.20、1467.45kg/hm2,增幅分别为17.90%、19.55%,在3株栽培方式中比9万、15万株/hm2处理分别增产1134.00、1156.20 kg/hm2,增幅分别为6.00%、24.44%。结论]建议生产中红缨子的种植密度为12万株/hm2,种植方式为3株,可在同类地区中推广应用此栽培模式。

Effects of Different Planting Density and Patterns of ＂Red Tassel＂ Float Seeding on Its Agronomic Traits and Yield

Objective ] The aim was to explore the standardized cultivation techniques for the specified kind of sorghum in Jane Wine Company, namely ＂red tassel＂, and find out its optimal planting density and patterns. Method ] The comparison experiment on different planting density （90000, 120000 and 150000 plants/hm2） and patterns （double seedlings, triple seedlings） was carried out. Result] With increasing of density, the plant height, panicle length, rate of grain and 1000-grain weight were all decreased, and the economic characters of 90000 plants/hm2 were better; yield was the highest in 120000 plants/hm2, which was higher than that in 90000 and 150000 plants/hm2 by 400.20（17.9% ） and 1467.45 kg/hm2 （19.55%） in double seedlings pattern and by 1134.00 （6%） and 1156.20 kg/hm2 （24.44%） in triple seedlings pattern. Conclusion] During its production, it is suggested that planting density 120000 plants/hm2 and triple seedlings pattern are the optimal selection, which can be promoted and applied in the similar area.
