Planting Density is Influence of Growth, Quality and Yield of Sweet Sorghum Hybridization Sweet 1

文章研究了不同种植密度对杂交种甜高粱通甜1号生长发育、品质及产量的影响。结果表明,不同种植密度下单株分蘖数在生育前期消长明显,株高、茎粗、茎叶比、叶面积、光合色素含量和单株干物质积累在后期均呈显著差异;且品质、生物产量和含糖量受种植密度影响较大,处理间生物产量显著增加(P<0.05)。综合分析,种植密度为11.67万株/hm2,株行距10cm×60cm,可较好地协调群体与个体的生长,使生物产量和营养含量都达到较高水平。

This paper studies that different planting density is influence of growth, quality and yield of the Hybrid Sorghum ＂ sweet 1 ＂. The results show that on different planting density, growth and decline of plant tillering number is Obvious in early growth stage, plant height, stem diameter, proportion of stem and leaf, leaf area, photosynthetic pigment content and dry matter accumulation show significant differences in the late; quality, biological yield and sugar content influence by planting density is big, the biological yield increased significantly between treatment （ P〈0.05 ）. Comprehensive analysis show that planting density is 116700 strains/h2, spacing is 10cm× 60cm, can better coordinate collective growth between group and individual ,biological yield and nutrient content have reached a higher level.
