合理的栽培方式是获取大豆高产的一条重要途径。夏大豆的栽培一般有与玉米、高梁、谷子等高秆作物间作的,有清种的方式。间作方式从整个复合群体看是有利于对光能和地力的利用,但对大豆来说,由于高秆作物遮阴的影响,产量一般不高。清种的大豆,在水肥条件较好的情况下,由于冠层(直接接受阳光照射的叶片的总称)叶片相互搭接,冠层以下的各层叶片往往因光照不足而大量变黄脱落,限制了产量的提高。如果 Reasonable cultivation methods is an important way to obtain high yield of soybean. Soybean cultivation in general with corn, sorghum, millet and other high-stalk crops intercropping, a way of clearing seed. The intercropping approach is conducive to the utilization of solar energy and fertility from the perspective of the entire composite population, but for soybean, the yield is generally not high due to shading of high-stalk crops. Clear seeding soybean, water and fertilizer conditions in the case of better, due to the canopy (directly under the sun exposure of the leaves) lap overlap each other below the canopy layers of leaves often due to insufficient light and a large number of yellow off, limiting Increase in production. in case
