采用先进的栽培技术生产大豆,平均亩产可达500斤左右.只有在上地肥力高、气候条件好的年份,并采取增产措施,才能超过600斤.要突破800斤,必须以作物能够较多地截取阳光为基础.因为较高的产量,与能量吸收、增加能量转化效率和减少生产产品的束缚能量密切相关.通过早播,延长大豆出苗和开花之间的时间;缩小行距,使整个叶冠均匀地布满行间;合理的群体以及分枝性的品种等.这些对于较多地截取阳光都是有效的.
Soybean production using advanced cultivation techniques, the average yield per acre up to about 500. Only in high fertility, good climatic conditions and take measures to increase production in order to exceed 600 pounds. To break through 800 pounds, the crop must be able to compare More interception of the sun as the basis because of the higher yield, and energy absorption, increase energy conversion efficiency and reduce the binding energy of the product is closely related to the production of soybean by early seeding, to extend the time between emergence and flowering; reduce row spacing so that the whole Leaf crowns evenly spread between rows; reasonable groups and branched varieties, etc. These are more effective at intercepting sunlight.
