1.严格控制密度6A高粱茎秆软、穗大、穗重,易倒伏,种植密度过大会加重倒伏。所以,控制种植密度是防倒、创高产的重要措施之一。沈阳市1984年6A高粱密度试验结果表明,每亩4,762(1.8×0.7尺)～5,880株(1.7×0.6尺)基本不倒伏或倒伏很轻,而且千粒重较高,产量高。在生产中要掌握“肥地宜稀,薄地宜密”的原则,密度大的不宜超过6,000株,稀的不应少于4,500株。2.播种不宜太早 1. Strict control of density 6A sorghum stalks soft, spike large, spike weight, easy to lodging, planting density over the General Assembly increased lodging. Therefore, the control of planting density is one of the important measures to prevent down and create high yield. The test results of the density of 6A sorghum in Shenyang in 1984 showed that 4,762 (1.8 × 0.7 feet) ~ 5,880 plants (1.7 × 0.6 feet) per mu did not basically lodging or lodging very lightly, and had high 1000-grain weight and high yield. In production, it is necessary to grasp the principle that “the fertilizer should be thin and thin and the soil should be dense”, the density should not exceed 6,000 and the density should not be less than 4,500. 2 sowing should not be too early
