This year, the peanut fertilization link in our province will focus on the promotion of increased application of organic fertilizer + bacterial fertilizer, improve soil fertility, improve soil fertility, lay the foundation for reducing the use of chemical fertilizers, and promote the improvement of the ecological environment. It is necessary to formulate the application of chemical fertilizers, increase the application of slow-release chemical fertilizers, and control nitrogen in a timely and appropriate amount to ensure a continuous and balanced supply of nutrients. It is necessary to apply chemical fertilizers scientifically to completely solve the outstanding problems of burning seeds, empty shells, and rotten fruits. Increase the application of organic fertilizer + bacterial fertilizer and improve soil fertility. All regions must vigorously promote the technology of returning straw to the field, and do a good job of returning wheat straw to the field with smashing and covering, and crushing and pressing corn stalks to return to the field. It is necessary to broaden the sources of fertilizer, increase the application of farm manure, increase the content of soil organic matter, improve the soil structure, and improve the fertility of the soil. For high-yield research fields, generally use 4-5 tons of fertilizer per mu or 1 to 1.2 tons of decomposed chicken manure; high-yield demonstration fields generally use 3-4 tons of fertilizer per mu or 0.8-1 tons of mature chicken manure; medium and low-yield fields generally use 2-3 tons of fertilizer per mu 0.4 to 0.8 tons of decomposed chicken manure. It is forbidden to use unripe chicken manure, livestock manure, etc. Biological (bacterial) fertilizer can improve some fixed nutrient elements in the soil, stimulate root growth and enhance nutrient absorption, reduce the amount of fertilization of corresponding nutrient elements, improve peanut resistance, and increase yield. Therefore, the increase of organic fertilizer should be combined with the use of biological bacterial fertilizer to promote the rapid improvement of soil fertility. Balance the application of chemical fertilizers to ensure a comprehensive and continuous supply of nutrients. The application of chemical fertilizers requires soil testing and formula fertilization. High-yield research fields generally apply pure nitrogen 12-14 kg, phosphorus (phosphorus pentoxide) 10-11 kg, potassium (potassium oxide) 14-17 kg, calcium (calcium oxide) 10-12 kg per mu; high-yield demonstration fields generally apply per mu Apply 8 to 10 kilograms of pure nitrogen, 6 to 8 kilograms of phosphorus, 9 to 12 kilograms of potassium, and 8 to 10 kilograms of calcium; medium and low yield fields generally apply 4 to 7 kilograms of pure nitrogen, 3 to 5 kilograms of phosphorus, and 5 to 6 kilograms of potassium per mu , 6 to 8 kilograms of calcium. In recent years, the problems of soil acidification and pod husks have become prominent in our province. We must pay attention to the application of calcium fertilizers, and use calcium fertilizers such as gypsum, lime, and superphosphate as appropriate to promote fruiting and fullness of pods. To apply conventional chemical fertilizers and slow and controlled release fertilizers together, 1/3 of the available nitrogen fertilizer and 2/3 of the slow and controlled release nitrogen fertilizer can be used as seed (seedling) fertilizer to ensure a balanced supply of nutrients. At the same time, according to the abundance and deficiency of soil nutrients in different regions or plots, micro-fertilizers such as boron and zinc should be applied according to local conditions. 0.5-1 kg of boron fertilizer and 0.5-1 kg of zinc fertilizer can be applied per acre. Scientific application of chemical fertilizers to improve fertilizer utilization efficiency. High-yield plots use more fertilizers. A combination of concentrated and dispersed fertilization methods should be adopted, that is, all organic fertilizers, phosphorus and potassium fertilizers and 2/3 of slow and controlled-release nitrogen fertilizers are sprayed before the cultivated land, and the land is harrowed. Apply the remaining 1/3 of the available nitrogen fertilizer and other fertilizers (calcium fertilizer, etc.) before spreading. Part of the fertilizer can be applied to the middle of the ridge with a planter fertilizer applicator on the machine-seeded plot. For ridged sowing plots, 2/3 fertilizer packs can be applied in combination with ridging 10-15 cm below the seeds of the two sowing rows to achieve deep and even application; the remaining 1/3 of the fertilizer is applied in the middle of the ridge, Appropriate shallow application. For low- and medium-yield plots, it can be combined with sowing as seed fertilizer for centralized application, but the seed fertilizer must be isolated to prevent seed burning. Calcium fertilizer should be used in conjunction with organic fertilizer to prevent excessive application of calcium from affecting the absorption of potassium and other nutrients.
