Avoid using corrosive fertilizers. Ammonium bicarbonate, ammonia water, etc., are volatile and corrosive, easy to smear 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 with toxic effects. During the growth of crops, urea often produces a small amount of adipic acid. If the content of the dicarboxylic acid exceeds 20%, it will be toxic to seeds and seedlings. 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 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 burns seedlings; ammonium nitrate, potassium nitrate and other fertilizers contain nitrate ions. It has a toxic effect on seed germination.
Avoid using 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 unfertilized human feces. Generally, farmer manure such as manure and manure that has been fully decomposed can be used as a seed fertilizer, and is applied near the seed at the time of sowing, and the effect is good. 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 and burns the seedlings. Farm manure and other farmyard manures must be fermented at high temperature and fully fermented before they can be used as seed fertilizers.
