玉米“宽窄行等株距”和“宽窄行一穴双株”种植模式对比试验

Comparison Test on Corn Row Spacing and Row One Hole Double Strain Planting Pattern

针对目前玉米"宽窄行一穴双株"和"等行距种植"模式存在易倒伏和产量不够稳定的情况,针对性地开展玉米"宽窄行等株距"与"宽窄行一穴双株"两种模式对比试验。结果表明:种植密度在4 600~5 500株/0.067 hm^2的情况下,"宽窄行等株距"模式比"宽窄行一穴双株"模式玉米单产平均高32.14 kg/0.067 hm^2,增幅3.64%。对于宽窄行等株距玉米种植模式,在5 000株/0.067 hm^2,宽行行距为80 cm,窄行行距为45 cm,株距均为21 cm时,"宽窄行等株距"模式种植的玉米单产最高达951.15 kg/0.067 hm^2。

Aiming at the current row hole double line row planting pattern are easy to lodging and yield is not the ideal situation, to carry out corn wide narrow row spacing and plant spacing and a row hole double line planting pattern comparison test. The results showed that the plant density in the 4600-5500 plants / 667 square meters, wide narrow row spacing cultivation of maize is higher than row of two plants per hole were planted maize yield, average high 32.14kg/667 square meters, average high is 3.64%. For wide and narrow row spacing of maize cropping patterns in 5000 plants per 667 square meters, broad row of 80 cm, narrow row to 45 cm, spacing in the rows were 21 cm, wide narrow row spacing cultivation of maize yield the most high of 951.15kg/667 square meters.
