Shallow water planted hoe, moist Dingmiao. The planting of water should be shallow, and when it is planted, the seedlings should not float, and when it is planted, it should fall into the water and keep the field moist. This will help set the seedlings quickly.
Inch water back to clear, thin moisture 蘖. After the rice is set, the paddy field should keep 0.5 to 1 inch shallow water layer to return to the Qing for promotion. A deeper water layer will inhibit delivery and postpone the delivery time, and cause high delivery; shallow water layer will lead to excessive birth, consume plant nutrients, and form a large number of invalid childbirth.
Enough seedlings field, control the seedlings. When the number of seedlings in the field reaches 80% of the expected number of panicles, it is necessary to properly drain the field to control late delivery. When drying up in the fields, let the water drain and dry for 3 to 5 days, then add new water, keep the water for 2 to 3 days, and then put the water to dry. In this way, it will reciprocate for 2 to 3 days.
Foot water boot, wet and dry seeds. Rice needs sufficient water at the booting stage, and paddy fields should maintain 1 to 2 inches of water to ensure that there are more panicles and grains. The paddy field water layer during heading should be 0.5 to 1 inch. If the field is not dry enough at this time, not only does the earing come out, it may even cause no ears to emerge. After the grain-filling stage, dry-wet alternating intermittent irrigation should be carried out to promote the transfer of organic matter from the plant to the grain, reduce the pods in the shell and increase the dry weight. After entering the yellow ripening stage, the paddy fields should be drained and drained. This will not only make the grain full and full, but also conducive to field harvesting.
According to the water requirement law of rice, scientific and reasonable irrigation at different stages of growth and development is an important technical measure to capture high yield and stable yield of rice. Its irrigation technical essentials are:
