How to increase the yield of rice? High-yield planting and Management techniques of Rice

Rice is a key crop in our country. Although the price of rice is not so high, it cannot be lacking, so rice can be planted every year. As far as rice cultivation is concerned, production is very important, so how can rice cultivation improve efficiency? Let's master it together.

1. When selecting seeds in scientific research, agricultural producers must select seeds that can be integrated into the natural environment of growth and development and have a certain ability of disease resistance according to the characteristics of the local natural environment. When purchasing seeds, agricultural producers must investigate in many aspects and buy seeds at retail outlets with guaranteed quality, so as to ensure seed quality as soon as possible and show resource advantages for rice cultivation. After the purchase, agricultural producers must carry out seed dressing to solve the problem. Generally, 98% Batan powder and 3% triadimefon aqueous solution are selected to soak the seeds in order to improve the seed characteristics.

2. Planting technology is accompanied by the marketing promotion of agricultural mechanization, and now it is all planted with specialization. According to the different planting methods, the specific time of planting is also different. for example, the planting time of rice in direct sowing room is generally earlier than that of planting rice. All over the rice fields on the hillside, the foundation is hand-made sowing, and the rice seeds after total mixing are evenly sown on the surface of the box, so as to ensure the relative density of the seeds to be symmetrical and can be divided into patterns when combing along the street. The work of checking and replenishing seedlings in the field should be carried out immediately 20-25 days after planting, so that the rice plants are symmetrical and the individual growth and development is balanced.

3. Cultivation technology is particularly important in the whole process of rice planting, which immediately harms the actual effect of rice plant growth. At the fertilizer level, the key is to use organic fertilizer, urea solution and diammonium phosphate as base fertilizer. Fertilization is carried out when rice is found to be poor or yellow, and the amount of fertilizer application is generally controlled at the release of urea solution 1kg per 664m2 of rice. In addition, attention must also be paid to the release of chemical fertilizers at the booting stage of rice, according to the method of releasing ammonia sulfate 7.5kg per 664m2 of rice to ensure production. In view of the irrigation work, the decision must be made according to the growth and development of rice, and effective irrigation must be carried out on the basis of paying close attention to the growth and development of rice. The developmental process of rice will be harmed by weeds, so herbicide, butachlor and other drugs can be used in weeding work.

4. Pest control (1) sheath blight. In the whole process of treating sheath blight, 5% Jinggangmycin 100mL 50kg can be used to spray to reduce the damage of sheath blight to rice main stem. Sheath blight can be prevented according to early fertilization and excellent cultivation techniques. (2) Rice blast. According to the fact that rice blast has a serious blocking effect on rice production, agricultural producers must always pay attention to the occurrence of rice blast and be able to select resistant varieties or seed dressing to prevent the occurrence of rice blast. 2000 times of 80% antimicrobial solution can be selected to invade seeds to maintain the prevention of rice blast. For the rice that has already suffered from the disease, it can be sprayed with 1000 times of Daomaoling EC in order to achieve excellent therapeutic effect. (3) Chilo suppressalis. Chilo suppressalis is one of the key diseases and insect pests in the whole process of rice growth and development, with a large total number and laying eggs quickly, which seriously harms all the normal growth and development of rice. In the prevention of Chilo suppressalis, traps can be placed to catch diseases and insect pests, and sex traps can be placed to trap and kill males, so as to reduce the total number of males and indirectly reduce the number of eggs. (4) Rice planthopper. There are many types of rice planthopper, including gray planthopper, brown planthopper and white-backed planthopper. When carrying out the prevention of rice planthopper, agricultural producers can choose 25% aphid suspension mixed with 40kg water and sprayed in the way of sprayer to maintain the prevention of rice planthopper and ensure rice production.

That is to say, the detailed introduction of improving the efficiency of rice, with the sustainable development trend of social development, everyone's requirements and quality regulations for rice have been gradually improved. How to improve the actual effect of rice planting and ensure the quality and production of rice is very necessary. Do you have anything to fill in about rice planting?
