First, increase organic fertilizers to protect and improve soil fertility. All localities must vigorously promote the technology of returning straw to the field, and do a good job of wheat stalks crushing and returning land, and corn stalks crushing and turning to return to the field. It is necessary to establish a planting and breeding demonstration area, do a good job in the construction of livestock and poultry manure resource utilization infrastructure, build an organic fertilizer plant (stacking pond), and guide farmers to increase organic manure. It is necessary to broaden the sources of fertilizer, increase farmyard manure, increase soil organic matter content, improve soil structure, and cultivate fertility. High-yield farmland generally 4 to 5 tons of Mushi circle fertilizer or 1 to 1.2 tons of decomposed chicken manure; high-yielding demonstration field generally Mushi circle 3 to 4 tons or chicken manure 0.8 to 1 ton; medium and low yield fields generally Mushi circle fertilizer 2 to 3 Tung or decomposed chicken manure 0.4 to 0.8 tons. Avoid using unfamed chicken manure, animal dung, etc.
Second, the balanced application of chemical fertilizers to ensure the continuous supply of nutrients. N, P, and K are applied. High-yield fields generally require 12 to 14 kg of pure nitrogen, 10 to 11 kg of phosphorus (phosphorus pentoxide) and 14 to 17 kg of potassium (potassium oxide), and 8 to 10 kg of pure nitrogen for high-yield farmland. ~ 8 kg, 9 ~ 12 kg of potassium; low-yielding fields generally 4 ~ 7 kg of pure Mushi nitrogen, phosphorus 3 ~ 5 kg, potassium 5 ~ 6 kg. To apply conventional fertilizers and slow-release fertilizers. One-third of available nitrogen fertilizers can be used as seed (vegetable) fertilizers, and 2/3 slow-release nitrogen fertilizers can be used as fruit fertilizers to ensure balanced supply of nutrients. At the same time, according to the conditions of soil nutrient abundance in different regions or plots, boron, zinc and other micro-fertilizers can be applied in accordance with local conditions. Each can use 0.5 to 1 kg of boron fertilizer and 0.5 to 1 kg of zinc fertilizer. Pay attention to the application of calcium fertilizer to promote fruitfulness and fullness. Alkaline soil can be applied to 50-80 kg of Mushi gypsum, acidic soil Mushi 30 to 50 kg of lime or 20 to 30 kg of lime nitrogen.
Third, scientific application of chemical fertilizers to improve the efficiency of fertilizer use. High-yield plots have more fertilizer, so a combination of centralized and decentralized fertilization methods is required. That is, all organic fertilizers, P and K fertilizers, and 2/3 slow- and controlled-release nitrogen fertilizers are applied before planting. Available nitrogen fertilizers and other fertilizers (calcium fertilizers, etc.) can be used to broadcast part of the fertilizer with a seeder fertilizer application device in the middle of the ridge. Rilling the sown plots, combined with ridging, applies 2/3 kinds of fertilizers to 10-15 cm below the two sowing lines, and the remaining 1/3 kinds of fertilizers are applied in the middle of ridges to achieve deep and uniform application. The middle and low-yield plots can be used in combination with seeding for concentrated application of seed fertilizers, but seed isolation is required to prevent burning. Calcium fertilizers should be combined with organic fertilizers to prevent the adverse consequences of excessive calcium application.
It can prevent some medicine or blood from splashing on the face, thus protecting the eyes. This kind of glasses is generally used in conjunction with masks and surgical caps to fully protect the doctor's head.
[Functions of medical eye masks]
1. Prevent blood, potion and other liquids that cause damage to the skin from causing unpredictable damage to the eyes.
2. It can prevent the impact of objects on the eyes during close surgery.
3. The inner space of the eye mask is large enough for doctors who wear myopia glasses.
4. The breathability must be good, generally there are vents
