Before rice transplanting, we must first prepare land. Use a rotary cultivator or leeches to level the field surface and the height difference should not exceed 3 to 5 cm. The time for soil preparation should be determined according to the transplanting time. The soil is planted 1 day before the transplanting of sandy loam, 2 to 3 days before the transplanting of loam soil, and 3 to 4 days before the transplanting of clay. Phosphate fertilizer, potash fertilizer, and silicon fertilizer should be mixed as the base fertilizer and mud during site preparation.
When the average daily temperature is stable at 13°C, the suitable period for transplanting rice seedlings is 30 cm spacing, 12-13 cm spacing, and 3 to 4 plants per hole. Plants with high spike height, strong tillering ability, and hybrid rice can be inserted in 2 to 3 strains.
When transplanting, pay attention to the quality of transplanting, pull wire transplanting, straight line evenly, without missing a hole, the depth of transplanting is 2 cm. Paddy fields were transplanted with 1 to 2 cm shallow water, and rice fields were transplanted immediately to protect the seedlings.
2 to 3 days after transplanting, the water should be irrigated and the depth of irrigation should be 4 to 5 cm. At the seedling height of 2/3, this will prevent the rolling leaves from occurring and protect the seedlings. One week later, change the water. In the saline-alkali paddy fields, fresh water must be replaced. After 10 days, apply green manure and apply 5-8 kg of urea per acre. The rice transplanter will return to the green stage to spray the enemy locusts, scorpion scorpion, butachlor, grass crumbs, and shrines for weeding. For a small amount of special grass, difficult to remove the large grass to be manually removed, preferably in the tillering period combined with Putian.
In the prevention of pests and diseases, we must guard against "rice water weevil." Its adults bite the leaves, and the larvae bite their roots in the water. The method for preventing and controlling it is to spray pyrethroid pesticides, such as insecticide, insecticide, carbofuran, etc., to spray on the field weeds during the site preparation, because the larvae of “rice water weevil†may lurk in the weeds. in. Dosage with reference to the instructions, the pesticide can be sprayed on the field lice once; if no pesticide is sprayed on the ridge, after the transplanting, immediately spray the pesticide in the field again.
