According to the requirements of soil testing and fertilization and production of pollution-free agricultural products, in view of the problems existing in the current fertilization, combined with the actual situation of our district, the technical points of the 2006 spring formula fertilization are proposed for reference.
Water Rice mid-rice: The principle of formulating fertilization with heavy bottom, early chasing, medium control and post-complement. MU applies farmer's fertilizer 2000-2500 kg, high content "Keyuan" brand compound fertilizer 35 kg (one package), or acre with urea 22 kg or ammonium bicarbonate 60 kg, superphosphate 25 kg, potassium chloride 15 kg, The total nitrogen reaches 10-12 kg, the phosphorus does not exceed half of the nitrogen, and the potassium is about 10 kg. Phosphorus and potassium fertilizers are used as base fertilizer, 50-60% of nitrogen fertilizer is used as base fertilizer, 20-30% is used as panicle fertilizer, and 10-20% is used as grain fertilizer. The accumulated reclaimed rice fields will increase the application of phyto-fertilizer urea from 15 kg to 20 kg per acre 7-10 days after the first season of rice. Perennial squatting field increased the application of zinc sulphate 1-1.5 kg as the base fertilizer.
The principle of fertilization of corn: heavy bottom, early chasing, sharp attacking and panicle fertilizer, skillful application of rod fertilizer. The use of farmyard manure is 2000-3000 kg, the high content of "Keyuan" brand compound fertilizer is about 50 kg, the pure nitrogen is 13-15 kg, the ratio of nitrogen: phosphorus: potassium is 1:0.4:0.3-0.4, and the bottom fertilizer is 40%. 20% of seedling fertilizer, 40% of ear fertilizer, and 1 to 1.5 kg of zinc sulfate as base fertilizer.
High fertilization principle: apply enough base fertilizer, apply top dressing early, and re-apply pregnancy fertilizer. The use of farmyard manure is 2000-3000 kg, the high content of "Keyuan" brand compound fertilizer is 35 kg, and the pure nitrogen is 9-10 kg. 30% of the base fertilizer, 25% of the top dressing, and 45% of the booting. The seed is mixed with 2-4 g of ammonium molybdate to prevent anthrax caused by molybdenum deficiency.
Red 苕 fertilization principle: apply fertilizer, one tube to the end. 2,000 tons of ash and ash fertilizer is used as the base fertilizer, and 1,500-2,000 kilograms of manure water is used after planting. In mid-July, the amount of manure water is 1000-1500 kg, and the high content of “Keyuan†brand compound fertilizer is 10--15 kg or urea. 5 kilograms of armpits, medium and late acres with 100-150 kilograms of grass ash, before the harvest, combined with cultivating acre, using 2000 kg of manure water to split the mouth fat, one tube in the end.
Dadou Mu applies organic fertilizer 1000--1500 kg, high content "Keyuan" brand compound fertilizer 35 kg, or superphosphate 20--25 kg as base fertilizer, before the flowering with urea 5-8 kg. Seed dressing with ammonium molybdate, 4 g of ammonium molybdate per kg of seed, first mixed with 5% solution sprayed on the seed pile for 10 hours, or initial flowering period with 1 - 2.5% ammonium molybdate leaf spray.
