Management points after transplanting rice
1. Shallow irrigation or intermittent irrigation: After transplanting rice, the ability of the roots to absorb water and fertilizer is weak. At this time, the outside temperature is high and the wind is large. The transpiration of the leaves is relatively large. Therefore, after the transplanting, the water layer should be established immediately. Generally, 1/2 to 2/3 of the deep water should be filled with seedlings. After the rice returns to green, the water layer should be controlled within 3 to 5 cm of shallow water, which will help increase the water temperature and the ground temperature, and promote the seedlings early tillering and fast tillering. Or after the rice returns to green, it should be intermittently irrigated, that is, 3 to 5 centimeters of shallow water should be poured at one time, and it should naturally dry out. When the water in the fodder is still there, water is poured again when the field is dry, and so on.
2. Drying the field: drying the field not only can control the growth of invalid tillers, but also can increase the ventilation capacity of the soil to achieve the effect of strong roots and strong stalks and lodging resistance. Generally from the end of June to the beginning of July, when the rice is near the end of effective tillering, it is necessary to overwhelm the growth, cause early closure of the leaves, leave the leaves dark, shed under the leaves, no jointing yellow, and the soil is sticky and poorly drained. Low-lying plots are required to withdraw from the water for 5-7 days, but on the contrary, they are not sunned and replaced by deep-water floods. The field is whitened and the ground is cracked, the white root on the surface of the pool, and the color of the leaf are faded and straightened. This allows the rice plant to control and promote the strong stalk.
3. Prevent water leakage. Paddy fields should be checked regularly to prevent water leakage. Leakage can cause poor herbicides and affect the normal growth of rice, fertilizer and water after fertilization flows into other rice fields, resulting in greediness in other lands, and the rice fields do not grow well. In addition, the water layer of other rice fields will be deepened, causing the destruction of Ikei chains and so on. Therefore, after transplanting rice, it is necessary to constantly check the repair pool.
