First, the law requiring fertilizer The triticale grows fast, yields high, and consumes large amounts of nutrients from the soil. Therefore, it is necessary to apply fertilizers to ensure sufficient nutrients in the soil. Triticale is sensitive to nitrogen, so pay particular attention to the application of nitrogen fertilizer. Base fertilizer was removed and the main fertilization period was at the returning green stage and jointing stage. In addition, fertilizer should be replenished promptly after each castration. Second, fertilization management 1. Basal fertilizer for every 667 square meters of high-quality Organic Fertilizer 200 - 300kg, promote the return of straw to fertility. The amount of nitrogen fertilizer accounted for 50% - 60% of the total nitrogen applied during the whole growth period. Phosphorus and potassium fertilizers were all applied at one time. General application of fertilizer per 667 square meters 50kg, urea can also be used 15kg, 15kg of ammonium phosphate and the right amount of potash. There are usually two methods for spreading fertilization, such as spreading or furrowing. In areas where high levels of mechanization and broadcasting are carried out, fertilization can be combined with soil preparation, and the former corn stalks can be directly returned to the field. 2. Top dressing (1) Frozen water with fertilizer: For plots with weak pre-winter seedlings, composting with frozen water, applying 5 kg of urea per 667 square meters. (2) Returning green manure: It is decided whether or not to fertilize and fertilize according to the condition of the seedlings. When the seedlings are weak, the ditch can be topped with fertilizer, and each kg of 667 square meters of special fertilizer can be used for young or kg of urea. (3) Jointing fertilizer: Top dressing watering during the jointing period. The amount of joint fertilizer is generally about 50% of the total amount of fertilizer, and the remaining amount of nitrogen fertilizer is applied during the jointing period. (4) Topdressing after castration: As the castration takes a certain amount of nutrients, the topdressing should be added after castration. Appropriate amount of available nitrogen fertilizer and available phosphorus and potassium fertilizers can be traced, and a single application of nitrogen fertilizer also has a good effect of increasing production. Usually every 15 to 20kg of special fertilizer for 667 square meters, timely watering after fertilization. China Agricultural Network Editor
