After transplanting rice, scientific and reasonable water management according to different stages of growth and development is the basic technical measure to capture the high yield and stable yield of hybrid rice.
Thin moisture
After the seedlings enter the tillering stage, the shallow water irrigation should be the main method. In general, 0.5-1 inch water layer should be kept in the paddy field. If the depth is too deep, the delivery will be delayed and the delivery time will be postponed, causing a high level of childbirth; the shallow water layer will lead to excessive childbirth. Consumption of plant nutrients, resulting in a large number of invalid childbirth.
Controlling seedlings in the field
When the rice reaches a certain number of tillers, it is necessary to drain the water properly to control the late delivery. However, the sun must be developed because of the time, in the absence of guaranteed water sources, weather forecast may occur in areas with summer drought and drought, you can not blindly dry the field, otherwise it will result in the lack of water in the middle and late stages of the hybrid rice.
Foot water booting spike
Rice needs sufficient water in the booting stage. In this stage, paddy fields should maintain 1 to 2 inches of water. During the headwatering of shallow water, the paddy field water layer should be 0.5 to 1 inch. If the water in the paddy field is not affected by drought, not only the ears are uneven, but even the ear can not be extracted.
