1. How to use corn seed fertilizer 1. Seed dressing: humic acid, biological fertilizer and micro-fertilizer can be used to dissolve the fertilizer, spray it on the corn seeds, and mix while spraying, so that the fertilizer solution evenly sticks to the surface of the seeds, and then sows after drying in the shade. 2. Seed soaking: dissolve the fertilizer to a certain concentration, soak the seeds in the solution for 12 hours, and sow the seeds immediately after drying in the shade. 3. Strip application or hole application: chemical fertilizer is suitable for strip application or hole application, the dosage is 2 to 5 kg, but the fertilizer must be separated from the seeds, and deep application is better, the depth is preferably 10 to 15 cm, urea, ammonium bicarbonate , Ammonium chloride and potassium chloride are not suitable for seed fertilizer. Second, the benefits of applying corn seed fertilizer The application of corn seed fertilizer is mainly to meet the nutrient needs of corn in the early stage of growth, and is mainly used in plots where the amount of base fertilizer is insufficient. Seed fertilizers are mainly available nitrogen and phosphorus fertilizers. Spring maize in high-cold areas is more prone to phosphorus deficiency due to low ground temperature in spring and slow release of available phosphorus. If high-quality decomposed organic fertilizer and phosphate fertilizer are mixed as seed fertilizer, the effect will be better. If there is no zinc fertilizer in the base fertilizer, you can dress the seeds with zinc fertilizer, and mix 6-8 grams of zinc sulfate per kilogram of seeds. When chemical fertilizer is used as seed fertilizer, the dosage should not be too large, so as not to affect the germination of seeds. Fertilizer should be applied next to the seed, 4-5 cm away from the seed. It can be applied in holes or in strips. 3. How to choose corn seed fertilizer 1. Choose fertilizing varieties, potassium chloride, ammonium chloride, and other chemical fertilizers that contain chloride ions, which will produce water-soluble chloride after being applied to the soil, which is unfavorable for seed germination and seedling growth, and even burns seedlings; ammonium nitrate, potassium nitrate, etc. Fertilizers contain nitrate ions, which are toxic to seed germination; ammonium bicarbonate is volatile and corrosive, and is easy to burn seeds and seedlings; urea produces a small amount of biuret, and if the content exceeds 2%, it will produce seeds and seedlings. Poisoned. These are not suitable for planting fertilizers, otherwise it is easy to burn buds and seedlings. Nitrogen, phosphorus, potassium compound fertilizers or slow-release fertilizers can be used. 2. Controlling the amount of fertilizer The amount of fertilizer required in the seedling stage of corn is small. In order to reduce waste, the amount of seed fertilizer should not be too large. Generally, the amount of fertilizer is about 10 kg per acre. Especially when the seedling is sowed, the amount of seed fertilizer should be strictly controlled. 3. Do a good job of seed fertilizer isolation when applying seed fertilizers, in order to avoid direct contact between seeds and fertilizers, resulting in burning sprouts and seedlings, separate seeds and fertilizers by 7-10 cm during mechanical sowing; when artificial sowing, fertilization should be side-by-variant. Deep application or deep application in interspecies acupoints. Disclaimer: Some articles on this website are transferred from the Internet.
