Experts teach you about balanced fertilization (3)

Maize and corn are high-water-tolerant and high-yield crops requiring large amounts of fertilizer. The implementation of balanced fertilization technology is an important measure to bring about a substantial increase in maize production. For each 100 kg of corn produced, about 2.22-4.24 kg of nitrogen should be absorbed from the soil, with an average of 2.57 kg; phosphorus (P2O5) 1-1.5 kg; potassium (K2O) 1.52-4.00 kg, with an average of 2.14 kg; The more nitrogen, phosphorus and potassium are absorbed. First, the requirements of corn fertilizer and fertilization principles Corn is very sensitive to nitrogen fertilizer, in the application of farmyard manure and phosphate fertilizer, in the range of 3-10 kg of urea per acre, 1 kg of urea can increase 6-11 kg of corn. Phosphorus is less required for corn, but it cannot be lacking. Phosphorus is lacking at the three-leaf stage, which will lead to the subsequent empty straw baldness. The corn is a zinc-promoting crop. Applying zinc fertilizer increases the yield by about 15%. The principle of fertilizing corn is based on organic fertilizer, re-applying nitrogen fertilizer, applying phosphate fertilizer, increasing potassium fertilizer, and applying micronutrient fertilizer. Farmyard manure and phosphorus, potassium, and trace fertilizers were used as base fertilizers, and nitrogen fertilizers were mainly topdressing fertilizers. Spring corn top dressing should be light before heavy, summer corn should be light before heavy. Second, the determination of the amount of corn fertilization tests show that: In the middle of fertility plots, each increase of 100 kilograms of corn need to apply 5 kg of nitrogen, phosphorus 2 kg, potassium 3 kg. The application of this amount of fertilizer is very simple. It is only necessary to multiply the number of kilograms of production increase by the amount of fertilizer required for a hundred kilograms of grain. This is only a reference calculation method, and the specific application should also be properly adjusted due to the differences in land use and species. The reference fertilization amount for the mu yield of corn is: 1500 kg of farmyard fertilizer, 9-11 kg of nitrogen, 4-5 kg ​​of phosphorus, 5-6 kg of potassium, and 1 kg of zinc fertilizer. Third, the fertilization method (A) spring ground corn shallow spring exposed live: The required phosphorus, potassium, zinc fertilizer and 2-3 kilograms of urea together with the farmyard fertilizer, applied into the kind of hole, suitable for planting. The remaining nitrogen fertilizer is left as top dressing. The mulching film in the mountainous area covers the live corn: the mulching corn grows stronger and consumes more nutrients. It is necessary to use the phosphorus, potassium, zinc fertilizer and 70% nitrogen fertilizer as the base fertilizer for the whole growth period of corn. The method is: In the sowing between two rows of corn to open a deep 3-4 inches, about 8 inches wide groove. First apply the nitrogen fertilizer to the bottom layer, mix all the phosphorus, potassium and zinc fertilizers with the farmyard fertilizer and apply it on the nitrogen fertilizer. Then ridge cover soil, ridge height 2-3 inches, when the seeding film. (b) Seed Fertilizer For uncoated seeds, sowing seeds for 2-3 days before sowing, adding 2 or 3 RMB of water with zinc fertilizer, dressing 1.5-2 kg, and stuffing for 1 hour. At the time of sowing, the conditional peasant households use 20 to pick up about 2 people of animal manure urea and 2 kg of urea, sowing seedlings at the edge of the seedlings to reach Miao Qi Miao Zhuang. (C) top dressing 1, live spring corn exposed to light weight before. Nitrogen fertilizers were used to recover joint fertilizers (6-7 leaf stage) accounting for 1/3 of total nitrogen application, and horn fertilizers (10-11 leaf stage) accounted for 1/3. 2, live summer corn top dressing should be light before. Summer sowing of glutinous maize is very important due to the busy agriculture and the tight agriculture time, most of which are seeded with white seeds. The jointing fertilizer (5-6 leaf stage) should account for two-thirds of the total nitrogen application, and horn fertilizer (10-11 leaf stage) accounts for one third. 3. Transplanting corn to top-dressing: When transplanting, mu with 10 kg of urea or other nutrient content of other nitrogen fertilizer is mixed into human excrement. Put the nutrient seedlings first, and then cover the nests with leaching manure to replace the jointing fertilizer. To the trumpet period, apply about 15 kg of urea again. 4. Plastic film corn: Due to sufficient base fertilizer and long fertilizer effect, 30% of nitrogen fertilizer that is not applied per acre will be applied once in the bell mouth. The method is to apply a fertilizer hole every two corns and apply fertilizer.
