Jinxiang "garlic soil testing formula, package fertilizer" program requirements of garlic fertilizer characteristics: garlic, is a kind of hi potassium sulfur crops. In the growth process of garlic, the demand for nitrogen, phosphorus and potassium nutrients is the most potassium, followed by nitrogen and less phosphorus. Generally, 1500-2500 kilograms of fresh garlic are produced. Experiments have shown that for every 1,000 kilograms of garlic tubers produced, approximately 4.5 kg of nitrogen, 1.4 kg of phosphorus, 4.6 kg of potassium, 0.8 kg of sulfur, and 0.4 kg of magnesium are needed. During the growth cycle of garlic, garlic sprouts are stretched. Long-term to the garlic expansion period is the peak of its demand for fertilizer. There are two major problems in the cultivation process of Jinxiang garlic: First, the fertilizer supply problem of garlic (balanced fertilization problem). There are four major problems: (1) Pay attention to the base fertilizer, contempt for top dressing, and use too much fertilizer. (2) Jinxiang area is dominated by sand-type soil, which is air-permeable and permeable, and uses a large amount of available fertilizer, resulting in serious loss of fertilizer. (3) Too much nitrogen, more phosphorus and less potassium. (4) There is a serious shortage of trace elements and trace elements. These four major problems have led to a disproportionate proportion of various nutrients in the soil, and the salinization phenomenon has become increasingly serious, which has seriously affected the yield of garlic. Second, the nutritional absorption of garlic. Due to continuous cropping for many years, soil fertility has been declining and soil-borne diseases have become increasingly serious. The growth of garlic roots has been severely inhibited, resulting in a significant decrease in the nutrient absorption capacity of garlic. Jinxiang garlic package fertilization program: First, base fertilizer: In the amount of the use of farmyard fertilizer on the basis of 200 kg of chemical fertilizers can be used as base fertilizer (put in about 300 yuan). When fertilizing, it is necessary to isolate the seed fertilizer and prevent the burning of seedlings. (1) Organic fertilizers. Use 4,000 kg of farmyard fertilizer per acre, plus 50 kg of cake fertilizer or biological organic fertilizer (2) chemical fertilizer. Virtue brand potassium sulfate long-acting potash fertilizer 16-10-22, 200 kg per mu (about 300 yuan input) Second, top dressing: (1) reminder fertilizer: After returning green in spring, before the garlic sprouts extend, with water flushing Lion and horse brand high-nitrogen fertilizer (21-8-11 full-nutrition compound fertilizer), 25 pounds per mu, once every 10 days, a total of two times. (Following a total of 50 pounds of fertilizer, invested about 75 yuan) (2) promote head fertilizer: garlic sprouts after the extension period, with the water flush Shi Lion brand high potash fertilizer (12-12-17 full-nutrition compound fertilizer), 25 pounds per acre, Interval 10 days or so, a total of two times. (Following a total of 50 pounds of fertilizer and investing about 75 yuan) 3. Foliage dressing: (1) 15 days after seedling, spraying 1-2 times Lion King (diluted 900 times) and complex trace element fertilizers. (Dilution 6000 times), effective supply of zinc, iron, copper, manganese, boron, molybdenum and other trace elements, can improve the ability of garlic to resist cold and disease. (2) After returning green, spraying 1-2 times of lion and horse brand leaf nutritious fertilizer (900 times dilution) and compound trace element fertilizer pheromone (6000 times dilution) can greatly promote the leaves and leaves of garlic. Growth can improve the ability of garlic to resist cold and disease. (3) Before and after the growth period of pods, spray 1-2 times of lion and horse brand full-vegetative foliar fertilizer (diluted 900 times) and compound trace element fertilizer pheromone (diluted 6000 times), which can greatly promote garlic Garlic sprout grows, promotes the conversion from vegetative growth to reproductive growth, preventing the occurrence of a deficiency syndrome. (4) Before and after the garlic inflating period, spraying 1-2 times of lion and horse brand full-nutrition fruit fertilizer king (diluted 900 times) and compound trace element fat pheromone (diluted 6000 times) can effectively prevent the deficiency of the disease. The emergence of garlic garlic greatly promoted the expansion of garlic production and improve the product grade. Fourth, the use of garlic Ke Pu Ke, greatly promote the growth of roots, improve the ability of fertilizer absorption, so as to solve the nutrient absorption of fertilizers. At the same time, it enhances the ability to resist adverse conditions such as root-knot nematodes. 1, soaking before sowing: garlic Ke Pu Ke 100 ml per acre, diluted 100 times, soaking for 6 hours, remove it. 2. 2-3 weeks after emergence, spray once with garlic Kepler 250 times. 3. After two weeks of interval, spray once again with garlic Kapok 400 times liquid. Note: 1, using Ke Pu Ke, pay attention to soaking time and use concentration. 2. Keppke cannot be mixed with alkaline substances. Explanation (1) Main advantages of garlic recipes * Organic fertilizers and chemical fertilizers can be used in combination to effectively promote crop growth and to improve soil retention by water and fertilizer. * Pay attention to the proportional balance of a large number of elements. The ratio of N, P, and K meets the demand ratio of garlic to 3.2:1:3.3 of nutrient. (Utilization: 40% for nitrogen, 20% for phosphate, and 45% for potash) This solves the problem of less nitrogen and more phosphorus and less potassium. * Pay attention to the balanced supply of trace elements. Full nutrition, complete trace elements, can effectively prevent various symptoms of deficiency, improve crop disease resistance, and increase production. * Pay attention to the fertilizer form. The base fertilizer used contains both nitrate nitrogen, ammonium nitrogen and urea nitrogen, water soluble phosphorus and ammonium lemon soluble phosphorus, which not only improves the utilization of fertilizer, but also stimulates the growth of garlic. * Pay attention to the fertilization method: At the same time, three fertilization methods are used for fertilizing the base fertilizer and foliar fertilizer, which greatly improves the utilization rate of the fertilizer. * Pay attention to the brand, the selected fertilizer is elegant and the quality is guaranteed. Lion and Red Bull brand fertilizers are well-known brand fertilizers imported from Germany. Zhongde Brand Fertilizer Fertilizer is a large German-owned company, and is the only domestic manufacturer that uses Red Bull brand potassium sulfate as raw material. Explanation (2) Reasons and purposes of selecting fertilizers for garlic package formula 1. The use of Zhongde brand 16-10-22 compound fertilizer in base fertilizer is mainly because the formula contains both nitrate nitrogen, ammonium nitrogen, and urea. Nitrogen not only ensures the requirement of nitrate for the garlic, but also uses the long-term effect of urea nitrogen to increase the nitrogen fertilizer efficiency in the sand-type soil. 2. The top-ranked compound fertilizers of 21-8-11 and 12-12-17 of German lions and horses were selected for topdressing to solve the problem of supply of medium and trace elements from the roots. At the same time, the nitrate nitrogen in the lion horse brand fertilizer has a long-lasting effect on garlic. 3. The German lion horse composite fruit trace element composite trace element fertilizer was used to solve the supply problem of trace elements from the leaf surface. 4. Selection of garlic Kapok: to greatly promote root growth, improve the nutrient absorption capacity of garlic, and solve the nutrient absorption problem of fertilizer.
