Buckwheat has a short growth period, rapid growth, slender stems, and underdeveloped root systems. It is a crop that requires a relatively small amount of fertilizer. Generally, for every 100 kilograms of buckwheat grain, about 3.3 kilograms of nitrogen, 1.5 kilograms of phosphorus, and 4.3 kilograms of nitrogen are absorbed from the soil. The specific amount of fertilizer will vary depending on the soil texture, cultivation conditions, climate characteristics, harvest time, and production capacity. However, for drought-prone and cold mountainous areas, fertilization is the basis for high yields. Buckwheat fertilization should be based on "basic fertilizer, supplemented by seed fertilizer, topdressing supplements," "mainly organic fertilizer, supplemented by inorganic fertilizer," "nitrogen, phosphorus," the principle. Skillful application of basal fertilizer: basal fertilizer is a basic fertilizer that is applied to the deep layer of soil in combination with cultivation and soil preparation before buckwheat sowing. It is also called base fertilizer. Generally, 2000-3000 kg of farmyard manure is fully cooked per mu. The basal fertilizer can be applied to the topsoil evenly before the last ploughing. Skillful application of basal fertilizer not only can fertilize the soil, ripen the soil layer, and create high-yielding conditions, but also can effectively promote root growth and development and improve root absorption. At the same time, we can use the characteristics of “all-fertilizer†and “stability†of organic fertilizers to achieve balanced fertilization for the growth period and ensure steady growth. Clever application of topdressing: topdressing is to compensate for the deficiency of base fertilizer and seed fertilizer in the process of buckwheat growth and development. In different stages of growth, the absorption and accumulation of nutrient elements is different. After budding is developed, a large number of elements are needed. At this time, the supply capacity of soil nutrients is very low. Therefore, the amount of nutrient elements added to the top dressing is timely and the buckwheat stalks are added. The growth of leaves, the development and differentiation of buds, and the formation of grains have an important role in promoting. "Promoting bud fertilizer" generally see seedlings per acre topdressing urea 3-6 kg. Note: do not apply vigorous growth. The flowering period is the period when the quinoa needs the most nutrients, and it is necessary to pay attention to the timely supply of quick-acting nitrogen fertilizer such as urea to increase the healthy flowering rate and the seed setting rate. "Spend flower fertilizer" generally see seedlings per acre can be topdressed with urea 3-6 kg. The best choice for fertilization is on cloudy days or sooner or later. In addition, for the lack of fertility in the middle and late performance or performance of defertilization, can be applied with 1-2 times the spray fertilizer, usually 0.2% per kg of potassium dihydrogen phosphate solution can be evenly sprayed 50 kg of stems and leaves.
