Rice can not be separated from water for a lifetime, but the requirements for water are different in different stages of growth. The following four points are important:
Shallow moisture: After the seedlings have survived, they have survived to 10-15 days before entering the tillers. In order to promote early delivery, more childbirth, and strong growth, shallow water irrigation is required to maintain a half inch water layer on the surface.
Enough seedlings seedlings: Under normal circumstances, the effective delivery period of seedlings is about 20 days. When the number of tillers reaches the target, it is necessary to drain the field and control the ineffective delivery, so as to prompt rice to shift from vegetative growth to reproductive growth. The field will also depend on the sky, seedlings, and fields. Seedlings, Tianyu, Tian Fei, and soil sticking, should be put aside early; Miao Xiao, Tian Qing, Tian Shou, fertilizer can be put lightly.
Stratification of water layer: During the period of snoring, rice booties are very sensitive to water, neither dry nor flooded, and often maintain a half inch water layer.
Dry and wet and strong seeds: The rice is grouted until it is ripe, and the method of wet irrigation of the horse water is adopted to keep the field dry and wet.
