南通地区夏播大豆玉米带状复合种植品种及密度组合试验研究

Study on the Varieties and Density Combinations for Summer Soybean and Maize Belt Composite Planting In Nantong Area

为筛选适合南通地区夏播大豆玉米带状复合种植品种及密度,文章对2022年南通地区开展的大豆玉米带状复合种植品种比较试验和种植密度组合试验进行分析。结果表明,南通地区大豆玉米带状复合种植通豆13和江玉877产量水平较高。利用通豆13和苏玉10号进行大豆玉米带状复合种植的最佳株行距组合为:通豆13行距40 cm,株距10 cm;苏玉10号行距40 cm,株距10 cm;通豆13与苏玉10号行距为70 cm。

To select suitable varieties and densities for strip intercropping of soybeans and maize in Nantong area,the paper analyzed the varieties comparison experiment and planting density combination experiment of soybean and maize belt composite planting in Nantong in 2022.The results showed that the yield levels of soybeans and maize in strip intercropping were higher with the varieties Tongdou 13 and Jiangyu 877 in Nantong area.When the soybean and maize varieties were Tongdou 13 and Suyu 10,the optimal row space combination for the crops was:Tongdou 13 row spacing of 40 cm,plant spacing of 10 cm,Suyu 10 row spacing of 40 cm,plant spacing of 10 cm,and a spacing of 70 cm between Tongdou 13 and Suyu 10.
