Five points for summer corn fertilization
Most of the summer corns are mainly live after wheat, with poor ground and no fertilizer, fast growth, and short growth period. Therefore, early preparation for looting, reasonable fertilization is the key to seizing the high yield of summer corn. Take advantage of the favorable timing of fertilizer application. Jointing begins 25 days after the sowing of summer corn, and at the same time, ear differentiation begins. After 40 to 50 days after sowing, it is the period of differentiation of female floret, which requires the most water and fertilizer, which is the critical period for determining the yield. Therefore, about 45 days after sowing is a favorable opportunity for top-dressing of summer maize. According to the conditions of water and fertilizer, topdressing irrigated varieties of fertilizer can be selected after sowing 40 to 45 days, fertilizer, dry land can be selected after sowing 30 to 40 days top dressing, according to the situation determined to win. Available nitrogen fertilizers, ammonium bicarbonate, and ammonium nitrate can be topdressed on schedule, and urea must be applied 3 to 4 days in advance. Fractional fertilization and "one-shot" high-yield irrigated land can be divided into two fertilization. 20 to 25 days after sowing, 30% to 40% of the total fertilizer is applied, and 60% to 70% of the total fertilizer is applied 40 to 50 days after sowing. The dry land can be given enough time after the broadcast of 30 to 45 days. Appropriate fertilizing amount and its proportion of 400 to 500 kg of irrigated land can be applied to urea 20 kg, superphosphate 40 kg, potassium chloride 6 to 8 kg, zinc sulfate 1 to 2 kg; per mu 300 to 350 Kilograms of land can be applied per acre 15 to 20 kg of urea, 30 kg of superphosphate, 5 to 6 kg of potassium chloride, and 1 to 2 kg of zinc sulfate. Fertilizer deep application and fertilizer and water cooperation According to the national soil fertilizer test network test, urea application, nitrogen fertilizer utilization is only about 55% of buried facilities, that is, the application of urea fertilizer will lose about 50%. Therefore, regardless of urea, ammonium bicarbonate, ammonium nitrate, compound fertilizer should be buried, buried depth of 8 to 15 cm. After urea is applied, it is not suitable to water immediately. Watering effect is better after 3 to 4 days after application. Many people believe that the mushroom soup is delicious. Why do mushrooms taste so fragrant? According to He Jiguo, this is mainly because mushrooms are rich in delicious amino acids. The sources of umami in mushrooms are mainly flavorful amino acids such as glutamic acid and aspartic acid, as well as taste nucleotides such as inosinic acid and guanylic acid. These substances make mushrooms taste delicious, comparable to meat .
