吉单631不同密度植株分蘖对产量及产量构成的影响试验,结果表明,玉米种植密度在2 000株/667 m~2、3 000株/667 m~2、4 000株/667 m~2、5 000株/667 m~2、6 000株/667 m~2时,去除分蘖或保留分蘖,对玉米产量无显著影响。种植密度4 000株/667 m~2时,去除分蘖、保留分蘖的产量最高。明确了吉单631在生产中保留分蘖,能达到省工省力,促进节本增效生产的目的。在生产中保留玉米分蘖,对提升该区域玉米高产高效生产能力具有促进作用。
The results showed that the planting densities of maize were between 2 000/667 m ~ 2,3 000/667 m ~ 2,4 000/667 m ~ 2, 5 000 plants / 667 m -2 2,6000 plants / 667 m 2, the removal of tillers or retained tillers had no significant effect on maize yield. Planting density of 4 000/667 m ~ 2, the removal of tillers, the highest yield retained tillers. Clear the 631 in the production of the maintenance of tillers, can save labor and energy savings, and promote the production of efficiency. Maintaining corn tiller in production can promote the high yield and high productivity of corn in this area.
