Integrated control techniques of rice diseases, insect pests, weeds and rodents
1. Suitable areas: Rice areas of Guangdong Province. The rodent damage control technology is suitable for rodent control in agriculture, forestry, aquaculture and cities and towns in Guangdong Province.
2. Key points of rice pest control techniques:
(1) Agricultural prevention and control: A. Select pest-resistant, high-yield and high-quality varieties. b. Sowing and transplanting at the right time. c. Reasonable close planting and fertilization. 40 plates (560 holes) per mu are suitable for throwing seedlings, and about 20 000 clumps (6X5 inch) per mu, that is, about 8-100000 seedlings per mu are suitable for planting. Base fertilizer advocates more application of organic fertilizer. According to soil fertility and yield, appropriate amount of nitrogen fertilizer (about 10 kg per mu of pure nitrogen) and phosphorus and potassium fertilizer should be applied in the early and middle stages. d. Reasonable drainage and irrigation, timely exposure to the field.
(2) protect and utilize natural enemies. Select pesticides with high efficiency and low toxicity, and prohibit the use of pesticides with high toxicity, high residue and killing natural enemies in large quantities.
(3) adopt correct measures of pesticide application. Concentrate on the use of drugs at the seedling stage to treat the seedling field and protect the field. In the middle stage, appropriate medication should be used according to the condition and condition of the insect. Attention should be paid to the control of panicle neck blast and glume blight at full heading stage.

Pollution-free control techniques of rice diseases and insect pests
Agricultural control is the basis of pollution-free control of rice diseases and insect pests. Its basic principle is to create an environment conducive to crop growth and growth but not conducive to the breeding of diseases and insect pests. 1. Increasing the application of organic fertilizer and gradually reducing the application amount of chemical fertilizer are one of the important reasons for the serious occurrence of rice diseases and insect pests. Therefore, we must change our concepts, attach importance to the development of animal husbandry, plant green manure and accumulate all kinds of farm manure, and establish an organic system.

Implement balanced fertilization according to the fertilizer requirement law of each crop, soil nutrient supply status and fertilizer effect, determine the corresponding fertilizer application amount and fertilization methods. Based on the principle of the combination of organic fertilizer and inorganic fertilizer and the combination of base fertilizer and topdressing fertilizer, balanced fertilization was realized. 2. Implement harmless organic fertilizer the organic fertilizer produced by farmers must go through ripening and fermentation, carry out harmless treatment, and kill pathogenic microorganisms, insect eggs and weed seeds. Prohibition of the use of industrial waste, municipal waste and sludge and failure to achieve
