How to manage moisture at heading and fruiting stage of rice? Please introduce that the middle and last ten days of July is the period when rice enters the period of heading and fruiting. The scientific nature of water management is very important to the yield and yield of rice. First, heading and flowering stage is the period when rice is more sensitive to water. Its sensitivity is second only to the late booting stage, heading in the high temperature season, transpiration and transpiration are very large, to meet the water supply and maintain the shallow water layer. Second, the water should not be cut off during the filling and fruiting period, the lack of water will affect photosynthesis and the transport of carbohydrates, but it can not be flooded for a long time, and long-term flooding is not conducive to root growth, so it is necessary to adopt the method of intermittent irrigation, that is, irrigation for 3-4 days to let it dry naturally, wet for 2-3 days, and then pour new water again and again until it matures. Third, after yellow ripening, the physiological water requirement of rice decreases, and it is generally drained and dried about 7 days before harvest to facilitate the harvest.
