| 摘 要： | 本试验用裂区设计,研究了大力士高粱在16种不同种植密度、3种种植方式下,产草量、生产速度、茎叶比、茎粗的变化情况。结果表明,在撒播密度为18 kg/hm2、条播为22.5 kg/hm2、穴播为28.5 kg/hm2时达到最高产量;生长速度在第53-55 d时最高,达5.7 cm/d;茎叶比随着产量的增加逐渐减少;茎粗随着种植密度的增大而有减小的趋势。

| Abstract: | This experiment arranged in a split plot design was congducted to study the effects of planting density and methods on the yield of growth,tatio of leaf and stem.the circumference of stem.The result showed that the yield of Hunnigreen forage sorghum was higher under the scatter planting,planting density, 18kilogram per hectare; the during planting density 22.5kilogram per hectare; bunch planting density 28.5 kilogram per hectare. The quickest speed of growth in 53-55days and reached 5.7 centimeters a Kay, The circumference of were concentrated on from 3.0 to 5.5 centimeters. And there is a trend of with increase planting density. |
