Current Rice Field Management Measures

1, scientific management of water: on the one hand to meet the rice growth and development of the water requirements; the other hand, use water to regulate and improve the environment of rice fields, water temperature, water to adjust fertilizer, with water to adjust gas, do: "Shallow water planting hoe, inch water back to green, thin moisture, timely field." 2. Early application of sub-fertilizer: early application of sub-fertilizer is an important measure to promote early-onset multiple low and sub-delivery. The tiller fertilizer should be applied promptly after returning green, mainly based on available nitrogen fertilizer. The amount of tiller fertilizer can be appropriately increased or decreased according to the soil fertility, the amount of base fertilizer, and seedling quality. Soil fertility is high, and base fertilizers, especially organic fertilizers, are sufficient. Rice fields may grow less vigorously, and vice versa. Fertilizer should be selected on sunny days. 3. Weeding in time: Rice field grasses are mainly grasses, and herbicides can also be applied manually to remove weeds in order to ensure normal rice growth. 4. Prevention and control of constipation; in our area, there were some rice fields in past years. The seedlings grew abnormally after transplanting. The growth was stagnant or stagnant, the rice plants were clustered, the leaves were stagnant, the leaves were dark green or yellow, and the root growth was blocked or made. Black, known as sit-in, should strengthen prevention and control and avoid reducing production. 5. Control of pests: The most common pests during rice returning to the tiller stage are aphids, rice planthoppers and thrips. At the time of childbirth, the main concern is the prevention of rice blast.
