Before rice transplanting, we must first prepare the land. Leveling the field with a rotary tiller or leeches, the height difference is no more than 3 to 5 cm. The land preparation time should be determined according to the transplanting time. The soil should be prepared 1 day before the transplanting of the loam soil, 2 to 3 days before the loaming, and 3 to 4 days before the clay transplanting . When preparing the soil, the phosphate fertilizer, potassium fertilizer and silicon fertilizer should be mixed with the mud and the mud.
When the daily average temperature is stable at 13 °C, it is suitable for transplanting. The transplanting specifications are 30 cm in row spacing , 12 to 13 cm in plant spacing , and 3 to 4 per hole . Two to three strains can be inserted in varieties with high plant height, large tiller, and hybrid rice .
When transplanting, pay attention to the quality of the transplanting, pull the thread, and straighten the hole. There is no shortage of holes and no seedlings. The depth of the transplanting is 2 cm. When the rice field is 1 to 2 cm in shallow water, the rice is transplanted, and the rice field is immediately inserted into the water to protect the seedlings.
After 2 to 3 days after transplanting , the water is filled with a depth of 4 to 5 cm, which is 2/3 of the height of the seedling . This can prevent the occurrence of curling and protect the seedlings. After one week, change the water. In the paddy fields of saline-alkali land, new water needs to be replaced. After 10 days, apply green fertilizer and apply 5 to 8 kg of urea per mu . Weeding, embedding, chlorhexidine, chlorhexidine, scorpion, etc. are used for weeding. It is necessary to manually remove a small amount of special grasses and large grasses that are difficult to dismantle. It is best to combine them with the field in the tillering stage.
In the prevention and control of pests and diseases, we must guard against the "rice water weevil". Its adult bites the leaf, and the larva bites the root in the water. The method of controlling it is to spray pyrethroid pesticides, such as insecticides, worms, carbofur, etc., on the weeds in the field, because the larvae of "rice water weevil" may lurk in weeds. in. According to the instructions, spray the pesticide on the field once. If there is no pesticide sprayed on the field, spray it with the pesticide in the field immediately after transplanting.
