In accordance with the requirements of “stabilizing grain supply, improving people's livelihood, and building a well-off society in an all-round wayâ€, we must have good methods for good rice cultivation in the rice production, and we should optimize the balanced fertilization technology, use 10,000 acres of precision quantitative cultivation, and create high yields. And other key measures. Scientific and technical personnel have in-depth production lines, and have given priority to scientific and technological training and strengthened the availability of practical production-enhancing technologies. To ensure that the rice planting in the normal season is over. From May to the beginning of June, the temperature is high and the light is strong, which is conducive to the early growth of rice. Some plots have a high groundwater level and long-term water accumulation. In addition, the large amount of Phosphorus fertilizer and phosphorus and zinc antibiotics and the improper treatment of seeds in Xiaochun beans cause different levels. The occurrence of abalone and bakanae disease. In response to the above situation, the current childbirth process puts forward the following major management measures.
1. Drying fields: Most of the rice in our city is planted from May 5th to 20th, and most of them enter the middle of tillering and reach the highest stage of stems and stems (the total number of stems reached 80% of the planned number and began to cut off water). Entering the best period of drying up the field, when the water is cut off, the ineffective tillering at N-n+1 leaf stage is effectively controlled, which changes the soil physical and chemical properties, renews the soil environment, and promotes the growth center from the leaf to the stem. Smoothly transfer, adjust plant appearance, promote root development, accelerate the disappearance of ineffective labor, optimize population structure, and enhance resistance to lodging. The degree of drying in the field depends on the soil and the soil. The seedlings with sufficient number of seedlings, dense leaves and high fertility should be exposed to the sun. The criterion is that Tanabe should open a large gap and open the “chicken claw crack†in the middle. The human body will not fall into place, and the leaves will obviously fall yellow; . It has been proved that sun drying is an indispensable measure in high-yield cultivation.
2. Control of Ralstonia solani: Ralstonia solanacearum is mainly caused by the absorption of physiological dysfunction in the roots of rice plants. Low-lying water, anti-acid field, cold paddy field, rusty iron paddy field, and soil have low effective zinc content. Due to long-term flooding, there are too many toxic substances and gases in the soil, overreducing effect is excessive, and oxygen is lacking. This disease can easily occur. For the field of low blistering cold water soaking blight, combined with drying field cultivating, timely drainage and drying field, Mushi 2-3 kg of zinc sulfate mixed fine soil application, and then 2-3% concentration of zinc sulfate aqueous solution Spray 2-3 times (spray every 5 days), the incidence of light field spray can be 2-3 times.
3. Bakanae disease: The primary source of the disease in this disease is mainly the bacterial rice and diseased bodies. With seed-borne disease as the main disease, adoption of disease-free seeds and seed treatment before sowing is the most effective method of prevention and control. However, there are still some rural households that have improperly disinfected seeds (the concentration of the solution is not enough, the time for soaking is not enough, and the drug is not properly selected, etc.). Some of the fields now have more or less bacillus strains. The only solution at present is the timely and thorough removal. In order to prevent the diseased plants from producing large numbers of conidia in the field, they will be transmitted from the air flow to the flower vessels for re-dip in the flowering stage of the rice, which will cause the rice strains to carry bacteria, or the diseased and healthy strains will be mixed and threshed to make the rice strains carry bacteria. Removing diseased plants is an effective way to reduce the initial source of the next year.
4. The Agricultural Land Reclamation: “Long-term drought must have long rain†According to the weather characteristics of the city, rain and heat in the same season, the majority of rainfall is concentrated in July-August. High temperature and high humidity are the main environmental conditions for the occurrence of diseases. Therefore, pest and disease prediction and forecast work must be done to prevent and control the occurrence of major diseases such as vegetative blight, leaf blast, ear blast, and rice smut disease in a timely manner to ensure high yield and yield of rice.
