谷子比较耐旱,但各个生育阶段的耐旱性不同。幼苗期需水少,需要蹲苗,水多了苗高苗细,后期容易倒伏。拔节到抽穗,需水量逐渐增加,抗旱力相对减弱。生育后期则怕涝,一般不必浇水。群众的经验是:前旱不怕旱,一遇掐脖旱,产量减一半。 Millet more drought-tolerant, but different stages of drought tolerance. Seedling less water, need to squat seedlings, juicy seedlings high seedling thin, late prone to lodging. Jointing to heading, water demand gradually increased, drought resistance is relatively reduced. Late childhood is afraid of waterlogging, generally do not have watering. The experience of the masses is that before the drought is not afraid of drought, once a case of pinch neck drought, output by half.
