What are the taboos for fertilizer and fertilizer use? Recently, many agricultural growers have consulted on the related issues of seed fertilizers. The purchase of fertilizer nets has collected some relevant knowledge points from the Internet. Fertilizer is the most economical and effective method of fertilization. It is applied at the time of sowing or transplanting. The nutrients required for the initial growth of the crop are supplied near the seed or mixed with the seed. Fertilizer is one of the methods of fertilization. Generally, there are two types of fertilization methods: base fertilizer and topdressing. Base fertilizer is one kind, it is applied before the crop is planted. There are many types of topdressing, which are generally referred to according to different growth stages of crops, such as seedling fertilizer, splitting fertilizer, jointing fertilizer, booting fertilizer, granular fertilizer, and spray fertilizer. Fertilizer is a single type, which is different from base fertilizer and top dressing. Simply put, seed fertilizer is a fertilizer that is applied to the seeding ditch together with the seed and is close to the seed. Fertilizer is an important method of scientific fertilization, but the application of seed fertilizer is technically strong, especially the choice of seed fertilizer is very particular. The improper use can easily damage the seed and its rooting and germination, thus delaying the season and causing losses. Fertilizer refers to fertilizer applied to or mixed with seeds when planted or planted. Appropriate application of fertilizers can meet the needs of crops for nutrients, and can save labor for topdressing. Conversely, it will harm seeds. Avoid strong alkaline fertilizers. Strong alkaline fertilizers include kiln ash potassium fertilizer and steel slag phosphate fertilizer. The kiln ash potassium fertilizer contains more calcium and has strong water absorption. After absorbing water, it forms mature lime, which releases a lot of heat and easily burns out seeds and radicles. When planting fertilizer, it must be mixed with organic fertilizer higher than 10 times, and applied to the lower layer of seeding ditch (hole). Do not directly contact the seed, and pay attention to covering the soil immediately after sowing to prevent damage. Avoid using the toxic fertilizer urea. During the growth of the crop, a small amount of adipic acid is often formed. If the content of the adipic acid exceeds 20%, the seed and the seedling will be poisoned. In addition, urea molecules with high nitrogen content penetrate into the protein molecules of the seed, denature the protein, and poison the seed germination and radicle. Avoid the use of corrosive fertilizers such as ammonium bicarbonate, ammonia, etc., which are volatile and corrosive, and easily smother seeds and seedlings. Superphosphate contains free sulfuric acid and phosphoric acid, which can cause damage to seed germination and seedling growth. Generally, it is not suitable for seed fertilizer. This type of fertilizer should be applied during tillage, or applied to the lower layer of the seeding ditch, not in direct contact with the seed, or mixed with soil and fertilizer. Avoid using fertilizers containing chloride ions Potassium chloride, ammonium chloride and other chemical fertilizers contain chloride ions, which will produce water-soluble chlorides when applied to the soil, which is detrimental to seed germination and seedling growth, and even burning seedlings. Fertilizers such as ammonium nitrate and potassium nitrate contain nitrate ions, which are toxic to seed germination. It is forbidden to use unfertilized human and animal manure, which can be used as a seed fertilizer after fully decomposed human and animal manure and other farm manure. It is applied near the seeds at the time of sowing, and the effect is very good. Farm manure and other farmyard manures must be fermented at high temperature and fully fermented before they can be used as seed fertilizers. However, if the unfertilized manure is used as a seed fertilizer, the fertilizer will release a lot of heat energy during the fermentation process, which not only causes burnt roots, but also releases ammonia gas to burn the seedlings.
