水肥充足的黑土地上紧凑型高粱杂交种内杂５ 号的最高产量为１０９８３ ｋｇ／ｈ ｍ ２（ 密度１０５０００ ｋｇ／ｈ ｍ ２） 。普通型高粱杂交种哲杂２０ 号最高产量为１０３６８ ｋｇ／ｈ ｍ ２（ 密度为８２５００ 株／ｈ ｍ ２） ；而干旱瘠薄的白五花土地上内杂５ 号的最高产量为７６５３ｋｇ／ｈ ｍ ２（ 密度１０５０００ 株／ｈ ｍ ２） ，哲杂２０ 号的最高产量为８４１８ ｋｇ／ｈ ｍ ２（ 密度８２５００ 株／ｈ ｍ ２） 。高粱的叶角与叶向值随种植密度加大而调节自身受光角度，调节幅度大小为植株上数第６ 叶以下叶片大于第６ 叶以上叶片，紧凑型高粱杂交种大于普通型杂交种。因此紧凑耐密高粱品种适于肥水条件好的地块种植，而普通型杂交种能在瘠薄的土地上获得较高的产量。各地应根据地力选择合适株型的品种
The highest yield of Neoza 5, a compact hybrid of sorghum on black soil with adequate water and fertilizer, was 10 983 kg / h m 2 (density 105000 kg / h m 2). The highest yield of common sorghum hybrid Zhezhao 20 was 10368 kg / h m 2 (density 82500 plants / h m 2), while the highest yield of Nei hybrid No.5 on the arid infertile land was 7653 kg / h m 2 with a density of 105 000 plants / h m 2. The highest yield of Zheza 20 was 8418 kg / h m 2 (density 82500 plants / h m 2). Sorghum leaf angle and leaf value with the planting density increased to adjust their own light angle adjustment range of the number of plants on the number of leaves below 6 leaves more than leaves 6 leaves, compact sorghum hybrids than ordinary hybrids. Therefore compact compact sorghum varieties are suitable for good land conditions in fertilizer and water cultivation, while ordinary hybrids in infertile land to obtain higher yields. All places should be based on the appropriate selection of plant type varieties
