Water management of rice field management technology

Fine management is a necessary means for stable production and high yield of rice. The means of management is to strengthen water and fertilizer management, water temperature regulation, and achieve the purpose of strengthening roots, strengthening stalks and promoting sputum, so as to achieve stable production, increase production, and high-quality production targets.

Shallow irrigation and irrigation

After rice transplanting, it is not suitable for flood irrigation. The shallow water is the main one. The depth of the water layer is half of the height of the seedling, and the maximum is not more than 2/3 of the height of the seedling. It cannot flood the seedling. This kind of water layer can prevent the leaf moisture on the one hand. Excessive transpiration leads to seedlings; on the other hand, it can also play a moisturizing role to prevent freezing of seedlings at night.

When the rice seedlings begin to return to green, the water should be released, and the shallow water layer should be kept at a depth of about 3 to 5 cm. This shallow water permeability is good, which is conducive to the improvement of water temperature and ground temperature, and can effectively promote the root development of the seedlings. The roots are fast, the new roots are many, and the seedlings can be divided early.

In addition, after the seedlings are returned to the green, they can also be irrigated in an intermittent manner. The water is irrigated 3 to 5 cm in shallow water, and then allowed to fall naturally. The water in the pits in the middle of the field is filled with water, and then water is irrigated and recycled.

The drying time is generally carried out during the period when rice is not sensitive to water. During this period, the number of stems in the basic field reached more than half of the planned number of stems, and the effective tillering of rice was basically terminated. If the rice plants grow too prosperous during this period, the canopy will appear earlier, the leaves will turn black, and the leaves will be draped. At the same time, if there is no joint yellow, or the soil with a relatively sticky soil and low terrain, it is necessary to carry out the drying of the field. Around the week, if there is no such situation, you can not dry the field.

The degree of drying the field should be determined by combining the seedlings and the soil. Basically, it should reach the whitish surface of the field, crack the ground, see the white roots on the pool surface, and the leaves are faded and straight, which can promote the strong stalk, control the upper part, and promote the development of the root system. Sunshine fields should also be combined with climate, soil, fertilizer supply and seedling growth to determine whether the field is dried or not, the degree of drying and the time of drying. The number of seedlings is sufficient, the leaves are thick, the growth is strong, and the fertility is high. The fields should be exposed to the sun and heavy sun. The people should not fall into the feet, and the leaves should be obviously yellow. On the contrary, they should be late, light or exposed. Tight skin, leaf color slightly faded.

Warming irrigation

In order to ensure that the irrigation does not cause the ground temperature to be too low and affect the growth of rice, it is necessary to carry out warming irrigation. For river water, the general irrigation time should be from 1 to 2 hours before sunset to 1 to 2 hours after sunrise. . If it is well water, first put the water into the suntan pool, extend the irrigation channel, widen the water inlet, and adopt surface water irrigation to ensure that the water temperature to be irrigated is not too low, and reduce the low water temperature on rice tillering and growth. Impact.

Check for leaks

After irrigation, the sturdiness of the ridges should be checked frequently to prevent water leakage. In the event of water leakage, the loss of fertilizers and herbicides will affect the growth of rice, but the effect of removing grass will be lost, causing excessive growth of weeds in the field. . If water flows to other water layers, it will cause the water layers of other fields to be too deep, affecting the growth of rice in other fields, and even causing the destruction of the field. Always repair the field rafts to ensure that there are no water leaks.
