1. Shallow water irrigation or intermittent irrigation: After rice transplanting, the ability of roots to absorb water and fertilizer is weak. At this time, the outside temperature is high and the wind is large, and the transpiration of the leaves is relatively large. Therefore, after transplanting, the water layer should be established immediately, generally 1/2~2/3 deep water with high seedling height, so as not to drown the heart. After the rice is greened, the water layer should be controlled to 3 to 5 cm of shallow water, which is conducive to raising the water temperature and ground temperature, and promoting the early tillering and quick tillering of the seedlings. Or intermittently irrigating after the rice is greened, that is, 3 to 5 cm of shallow water is poured once, until it is naturally dried, and when the water is in the socket, the water is refilled once, and the circulation is repeated.
2. Sun field: Sun field can not only control the growth of ineffective tillers, but also increase the ventilation capacity of the soil to achieve strong roots and strong stalks and lodging resistance. Generally, from the end of June to the beginning of July, when the rice is close to the effective tiller, the growth is too strong, the early closure of the canopy, the black leaves, the leaves under the cloak, the absence of "joint yellow" and the soily weight, poor drainage Low-lying plots, it is necessary to withdraw water for 5 to 7 days, and instead, it will not be sun-dried and replaced by deep flooding. The field is white, the ground is cracked, the white surface of the pool surface is seen, and the leaf color is faded and straight, so that the rice plants can be controlled to promote the strong stalk.
3. Prevent water leakage. The paddy field should be checked frequently to prevent water leakage. Leakage can cause poor herbicide effect and affect the normal growth of rice. The fertilized water after fertilization flows into other rice fields, causing other plots to be greedy, and the rice fields are not growing well. In addition, it will deepen other rice fields and cause damage to the pool chain. Therefore, after rice transplanting, it is necessary to check the repairing ponds frequently.
