水稻的气候土壤生产潜力估算模型

(1)作物的光和潜力Wi模型:

       

式中,Wi为第i时段内,单位土地面积上的光和潜力;Qi为第i时段内,投入该面积上的太阳辐射能;E为作物的最高光能利用率;Z为能量转换系数。

(2) 作物的光热潜力模型:

       

式中,,为叶面积订正系数,为当地作物丰产群体第i时段的实际叶面积系数;为温度订正系数,为第i时段的平均温度,T为作物光合作用温度。

(3) 作物水肥光热潜力模型:

1)     作物光热水潜力模型

         

式中,为水分订正系数。

2)     作物水肥光热潜力Y模型

         

式中,P为肥力订正系数。
