What fertilization methods crops use is a key issue for improving fertilizer utilization and increasing crop yields. Improper fertilization will not only result in waste, but also reduce the effectiveness of fertilizers and reduce income. Therefore, scientific and rational fertilization is an effective measure to increase fertilizer efficiency and increase crop yield. Organic manure and chemical manure combined with organic fertilization have full nutrition and long-lasting fertilizer effects. Chemical fertilizers have only a single nutrient, but they are high in content and effective. The combination of the two can complement each other and improve fertilizer efficiency. According to the experiment, livestock manure was applied in combination with ammonium bicarbonate, superphosphate, and potassium sulphate, which yielded more than 11.5% more than monocropping and other quantitative fertilizers. The reasonable ratio of nitrogen, phosphorus and potassium micronutrients, that is, formula fertilization, is based on factors such as fertilizer supply performance of different soils, fertilizer requirement rules of crops, and utilization ratio of chemical fertilizers to reasonably match various nutrient elements. Formula fertilization energy The earth improves fertilizer utilization and increases crop yields. According to tests, the utilization rates of urea, superphosphate, and potassium chloride were 32%, 13%, and 33%, respectively, and the formula fertilization utilization rate would increase to 58%, 35%, and 59%, respectively. For nitrogen fertilizers with deep applied urea and ammonium bicarbonate, shallow application, application or application of high concentrations should cause serious waste of fertilizer. According to experiments, urea and ammonium bicarbonate applied more than twice as much as fertilizer. Urea is an amide nitrogen fertilizer. After a higher nitrogen content is applied directly to the soil, except for a small amount of plants directly absorbed and utilized, most of the urinary enzymes secrete by the microorganisms and converted into ammonium nitrogen can be absorbed and utilized by plants. The nature of ammonium bicarbonate is not stable, and the utilization rate of shallow surface application is low. At the same time, nitrogen fertilizer has a large amount of top dressing and a high concentration. The ammonia gas that is volatilized will damage the stems and leaves of crops and cause fertilizer damage. The correct fertilization method is: nitrogen fertilizer should be applied as a topdressing or acupuncture, with a depth of about 10 centimeters. For the application of leaf fertilizer should be a good concentration. Wheat, cotton, corn and other 1% to 2% are appropriate. The spraying concentration of vegetables should be low. Centralized applications such as phosphate fertilizers have poor mobility in the soil and are easily fixed by iron, aluminum, and calcium in the soil and lose their fertility. Therefore, it should be applied and applied. Focus on the growth of soil in the root system, so that phosphorus is fixed around the seeds and roots, is conducive to root absorption, improve fertilizer utilization. The limited fertilizer was applied preferentially to the medium and low-level trials. In the high-yield, middle-production and low-yield fields of maize, the same effect of increasing the yield by applying 10 kg of urea and 10 kg of potassium chloride was different: on average, 1 kg of urea per gram was added, and the yield was high. Tian Zeng yields 2.8 kilograms of corn, 5.1 kilograms in middle-quality fields, and 7.8 kilograms in low-yield fields; on average, 1 kilogram of potassium chloride is added, 2.3 kilograms of corn are grown in high-yield fields, and 4.2 percent of corn is grown in middle-grade fields. Kilograms, low-yielding fields increase corn production by 6.7 kilograms. Single application of potassium fertilizer potassium sulfate, potassium chloride are water-soluble available potassium fertilizer, there is a weak physiological acidic reaction. After being applied to the soil, potassium ions are absorbed by the cations of the soil colloid and are fixed, making it difficult to use the crop. The correct application method is: Potash fertilizer will only play a greater role when mixed with nitrogen and phosphate fertilizers. Topdressing should be concentrated in the ditch or hole applied near the root system. The combination of zinc fertilizer and phosphate fertilizer has serious "antagonism" effect between zinc and phosphorus. If zinc sulphate and superphosphate are used together, the effect of zinc sulphate can be inhibited to a great extent to reduce its effectiveness. The correct application method is: zinc fertilizer and phosphate fertilizer should be used separately. Phosphorus fertilizer is used as base fertilizer and zinc fertilizer is used as top dressing. Or zinc fertilizer for basal fertilizer, phosphate fertilizer for topdressing, this can not only improve the efficiency of phosphorus fertilizer, but also improve the fertilizer efficiency of zinc fertilizer.
