水稻旱湿栽培,是在确保水稻生理需水,满足群体发育的前提下,最大限度地节省生态用水,除缓苗要求土壤水分基本饱和或有水层外,大部分生育期间土壤呈半湿半旱状态,即类似旱育苗床的湿润程度,是一种节水效果十分明显的栽培方法。 Dry cultivation of rice is to ensure that rice physiological water, to meet the development of population under the premise of saving the maximum ecological water, in addition to Huanmiao requires soil moisture is basically saturated or aquifer, most of the soil during growth was semi-wet half Dry conditions, that is similar to the degree of wet nursery bed, is a water-saving effect is very obvious cultivation methods.
