大豆玉米带状复合种植“2+4”模式下不同株距对大豆产量的影响

Effect of Different Plant Spacing on Soybean Yield under the "2+4" Model of Soybean and Maize Belt Compound Planting

摘要: 为探究适宜江苏省阜宁县大豆玉米带状复合种植模式，文章设定大豆9 877株/0.067 hm²、8 979株/0.067 hm²、8 030株/0.067hm²、7 598株/0.067 hm²、7 055株/0.067 hm²等5种种植密度处理进行对比研究。结果表明：大豆密度为8 979株/0.067hm²，即两行玉米+四行大豆，玉米株行距12.3 cm×40 cm，大豆株行距12.3 cm×30 cm，玉米与大豆间距70 cm，是产量最高、产值最优的株行距配置。

Abstract: In order to explore the suitable soybean and maize belt compound planting model in Funing County,in this paper,5 kinds of soybean planting density treatments,including 9 877 plants/0.067 hm~2,8 979 plants/0.067 hm~2,8 030 plants/0.067 hm~2,7 598plants/0.067 hm~2and 7 055 plants/0.067 hm~2,were set for comparative study.The results showed that the density of soybean was8 979 plants/0.067 hm~2,that is,two rows of maize+four rows of soybeans,the row spacing of maize plants was 12.3 cm×40 cm the row spacing of soybean plants was 12.3 cm×30 cm,and the spacing between maize and soybean plants was 70 cm.
