水稻插秧前,泡田、整地用水量较大,约占水田全年用水量的25～30％。近几年,全省各地推广的水田旱耙,是一项重大节水抗旱措施。它的好处是:1.节约用水:水田旱耙可缩短泡田时间,减少泡田用水量。据新民县辽蒲灌区1974～1977年实地计量,旱耙地泡田每亩用水90～130立方米;未经旱耙的用水150立方米左右,平均每亩节水40立方米。如按全省600万亩水田计算,仅此一项就可节省泡田用水2.4亿立方米,如果按每亩泡田用水量110立方米计算,可多泡田21.8万亩。
Before transplanting rice, soaking fields, land preparation greater use of water, accounting for paddy field annual water consumption of 25 to 30%. In recent years, paddy field dry rake promoted throughout the province is a major water saving and drought relief measure. Its benefits are: 1. Water conservation: paddy field dry rake can shorten the time to fry, reducing the amount of water used in froth. According to the field measurement in LiaoPu irrigated area of XinMin county from 1974 to 1977, the dry and harrow soaked fields used 90-130 cubic meters of water per mu for the irrigated land; about 150 cubic meters of water were used for dry raking; the average water saving was 40 cubic meters per mu. According to the calculation of 6000000 acres of paddy fields in the province, this alone can save 240 million cubic meters of water for soaking fields. If the amount of water used for soaking is 110 cubic meters per mu, more than 2188000 acres may be soaked.
