农田热量、水量盈亏计算公式

(1)       农田热量盈亏量计算公式:

1)     一年一熟制,一年两熟制农田热量平衡式:

    

2)     二年三熟制农田热量平衡式:

  

式中,K为农田热量盈亏量;H为某地某一指标积温年的年均温;ΔA为两种作物套种间的热量重复量;A为某作物的热量需求量;∑A为两种及两种以上作物热量需求量之和;G为逸散热量。

(2)       农田水量盈亏量计算公式:

式中,B为农田水量盈亏量;P为作物生育期的降水量;C为作物生育期地下水通过毛管补充给土壤的水量;E为作物需水量;R为作物生育期地表径流量;I为作物生育期降水补给地下的水量;W1-W2为作物生育期始末土壤水量之差。
