Pre-sowing wheat seed treatment is an important measure for disease prevention and pest control, and for promoting the growth of strong seedlings. There are many specific practices, which are summarized as follows according to the purpose of treatment: First, prevent disease 1. Variable temperature soaking. First pre-soak wheat seeds with cold water for 4~6 hours, remove and soak with warm water of 52~55°C for 1~2 minutes, make the seed temperature reach 50°C, remove and put into warm water of 56°C, keep the water temperature at 55°C, dip 5 minutes to take out, after cooling with cold water to dry sowing, to prevent the spread of wheat smut is very effective, but must strictly control the temperature and time. 2. Constant temperature soaking. Place the wheat seeds in 50-55°C hot water, stir immediately, and quickly reduce the water temperature to 45°C. Remove at this temperature and soak for 3 hours. Allow to dry and sow after cooling. It can effectively control wheat smut and red smut. Mildew, such as blight. 3. Lime water soaking. Dissolve 0.5 kg of high-quality quicklime with 50kg of water first, remove the residue and dip into the selected wheat seed, so that the surface of the water is higher than the seed l0 ~ 15cm, and keep standing, can not stir the water; soaking time depends on the temperature and the temperature: Immerse for 3~5 days at 20°C, soak for 2~3 days at 25°C, and only 1 day at 30°C. The soaked wheat seeds do not need to be rinsed with water, and can be sown after spreading and drying. They are good for the prevention of wheat smut, rod smut, head blight, leaf blight, and leaf blight. Effect. 4. Versitile spirit seed dressing. Using 75% active ingredient rustin wettable powder to seed 0.3% of the seed amount can effectively control wheat smut, and can concurrently treat wheat smut and wheat stem on wheat seeds or soil. Powder disease. 5. Triadimefon dressing. Triadimefon is a new type, high-efficiency, systemic fungicide, and it has special effects on various diseases of wheat. According to the experiment, 20% Triadimefon can be used to control seed smut, head smut and stem smut caused by 0.08-0.1% seed dressing; seed dressing of 0.2% can prevent and control wheat rust , powdery mildew and sheath blight; seed dressing 0.3%, can prevent and cure wheat whole rot and root rot. Second, control of underground pests 6. Methisophos or phoxim seed dressing. Use 100% 50% phoxim EC, 2 to 3 kg of water, 50 kg of mixed wheat seeds, and mix and boring 2 to 3 hours after mixing, and have special effects on pests such as cockroaches, cockroaches and wireworms. III. Diseases and Insects 7. Methylisophos-methyl (or phoxim) + triadimefon. In the mixture of underground pests and wheat full-blown, root rot, sheath blight, and smut, 50 ml of 40% methylisotriphos-peroxidase (or 100 ml of 50% phoxim EC) can be used, plus 20 % Trifenacin EC 50 ml, 2 to 3 kg of water, 50 kg of mixed wheat seed, mix and boring 2 to 3 hours after sowing. 8. "3911" + Triadimem seed dressing. With 75 ml of 3911 EC 150 ml, plus 20% Triadimefon 20 ml, 2 to 3 kg of water, and 50 kg of mixed wheat, can be used to treat wheat powdery mildew, root diseases, and underground pests and voles. 9.391l seed dressing. In areas where wheat virus disease (mainly bushy dwarfism and yellow dwarfism, etc.) predominantly occur, use 75 ml of 3,911 emulsion oil, 3 kg of water, 50 kg of mixed wheat seed, and mix well for 12 hours. It has special effects on the prevention and control of the transmitted insects, Laodelphax striatellus and wheat aphids, and can control both the vole and the underground pests. 10. Seed dressing dressing. Seed coating agent is a new type of medicine and fertilizer compound preparation specially used for the coating of crop seeds. It is different from the general seed dressing agent. When it is wrapped on the seed, it can quickly solidify into a film. When the seed is sowed into the soil, it will absorb water and swell, and the medicine and fertilizer will be released slowly. It can prevent and treat various pests and diseases and promote seedlings. The role of robust growth. When seed dressing, use 75-100g of seed coating liquid per acre, directly pour into the selected wheat seeds and mix evenly; according to the test, after treatment with seed coating agent, the yield of wheat can be increased by 5.1%~31.2% . Fourth, to promote the seedlings full Miao Zhuang 11. Chen urine soaking. Soak the wheat seeds with water for 4 hours, remove and dry them, and then put them in urine for 2 hours so that the wheat germinates early and grows robustly. 12. rabbit fecal soaking. The dried rabbit manure was crushed and mixed with boiled water at a ratio of 1:7. After cooling and filtering, the solution was soaked for 24 hours to increase the yield of wheat by 9.2%. 13. Potassium dihydrogen phosphate mix (immersion) species. With potassium dihydrogen phosphate 0.5 kg, 5 kg of water, evenly mixed with 5 kg of wheat seeds, heap boring for 6 hours; or soaked with a concentration of 0.5% potassium dihydrogen phosphate solution for 6 hours, remove and dry to sow, can Improve the phosphorus and potassium nutrition of wheat seedlings, and promote the roots under the bar, is conducive to seedlings full Miao Zhuang. 14. Zinc sulfate (immersion) species. 50 grams of zinc sulfate, dissolved in the appropriate amount of water, spray mixed in 50 kg of wheat, mix and boring after 4 hours, air dry sowing; or the selected wheat into 0.05% zinc sulfate soak 12~ 24 hours to prevent zinc deficiency during wheat growth. 15. Borax mixed (immersion) species. Dissolve 10 g borax in 5 kg water, mix it into a 0.2% solution and spray mix on 50 kg wheat seed; or soak the selected wheat seed in 0.01~0.05% borax solution for 6~12 hours. To prevent boron deficiency in the growing period of wheat. 16. Ammonium molybdate mix (immersion) species. Mix 2-6 grams of ammonium molybdate per kilogram of wheat, or soak the wheat seeds in 0.05-0.1% ammonium molybdate solution for 12 hours to prevent molybdenum from growing in wheat. 17. Soda soaking. The soaking of the soda solution with a concentration of 0.1% for 48 hours can make the wheat early mature and high yield; but the saline-alkali wheat fields should not be popularized. 18. Help the prime mix (immersion) species. Use 20 ml of booster, 2.5 to 3 kg of water, spray on 50 kg of wheat, mix and dry to dry, or soak for 10 to 10 hours with 100PPM of the medium, then remove and dry to sow. Wheat seedlings full seedlings. 19. Oil booster soaking. The petroleum enhancer is a plant growth stimulating hormone, and the main component is sodium naphthenate. Soaking seeds with a solution of 800 times petroleum enhancer for 12 hours can make the wheat emerge early, and the seedlings are strong and the root system is developed. 20. Paclobutrazol seed dressing. Use 15% paclobutrazol wettable powder 20~25g, add appropriate amount of water to dissolve and mix 100kg of wheat seed, mix well for 4~6 hours, air dry sowing, make the seedlings resistant to cold, drought, and can increase the nitrogen of the plant Absorption utilization. 21. Chlorothane mix (immersion) species. Use 50% Chlormequat 250 g, 7.5 kg of water, spray evenly on 50 kg of wheat, mix and slacken for 5 hours, or soak in 12 hours with a concentration of 0.5% of Chlormequat solution. Wheat seedlings grow robustly and enhance their ability to resist freezing and lodging. Fifth, enhance plant resistance 22. Drought-resistant exercises. 40 parts of fresh water shall be mixed with 100 parts of wheat seeds three times. After each addition of water, they shall be absorbed for a certain period of time and then dried to the original weight at 15 to 20°C. In this way, wheat can produce a strong adaptive response to drought conditions, thereby enhancing the plant's ability to fight drought. 23. Water retaining agent seed dressing. Use 50 grams of water retention agent per acre, add 5 kilograms of water, and sow with wheat seeds after mixing. Normally, the yield increases by more than 10%, and the higher ones reach 25%. 24. Fulvic acid seed dressing. Fulvic acid, also known as drought repellent No. 1, is a new type of plant growth regulator that can enhance the drought resistance of crops; 200 grams of fulvic acid, 5 kg of water, 50 kg of mixed wheat seeds, mix well, and then dry and sow. Improve seed coat water absorption capacity, speed up its physiological activities, promote the growth of young roots, increase production by 9.3~13.3%. 25. Phosphorus-boron mixed solution. Use high-quality superphosphate 3 kg, add water 50 kg, remove impurities after dissolution, add 50 g of boric acid in the filtrate, stir 5 kg of solution, stir 50 kg of wheat seed, and soak, so that the wheat seedlings grow robustly.
