补充资料:降水临界值
降水临界值
critical precipitation
1 iangshui liniiezhi降水临界值(eritieal preeipitation)在水分临界期内保证作物最小需水量的降水下限和最大需水量的降水上限值,其上、下限之间的降水量称为降水当量。降水临界值与作物的地区分布和作物类型有密切关系。如国家气象局对湖北省夫门、应城等县冬小麦降水临界期的研究,提出小麦抽穗前10一15天(水分临界期)的降水当量为30一90毫米,即在这一时段内降水量大于90毫米或小于30毫米都会使产量显著下降。而陕西省在小麦生育期内的4一5月份(水分I尚界期前后)适宜降水量的上、下限为90一110毫米。 在农业气象工作中常用降水临界最小值的概念,如北京地区壤质土,3一5月份冬小麦降水临界最小值为120一150毫米,这是保证小麦在3一5月份不受土壤干旱威胁的最少降水量。(龚绍先)
