Nutritive area

coefficient for defuse penetration(TD) and radiation penetration(TR) and leaf distribution(LD) were measured by CI-110 digital plant canopy imager system to soybean population differing in single plant nutrient area during growing season.

经过分析,不同营养面积所形成的冠层的指标参数是不同的,随着单株营养面积的减少,LAI逐渐增大;平均叶倾角先增大后减少;散射辐射和直射辐射逐渐降低,但是散射辐射始终大于直射辐射;叶片分布密度增大。
