"Taboo" during the peak period of fertilizer use in spring
In the beginning of spring, it is a good time for crops to replenish fertilizer. However, if the following 13 "taboos" are violated when fertilizing, it will not only avoid waste of fertilizer, but also cause crop damage. 1. Ammonium bicarbonate and urea cannot be mixed When fertilizing fruit trees in spring, urea and ammonium bicarbonate are generally applied. The amide nitrogen in urea cannot be absorbed by crops, and can only be absorbed and utilized by crops after being converted into ammonium bicarbonate under the action of soil enzymes. After the soil, it will cause the soil solution to be acidic in a short period of time, which can accelerate the volatilization loss of nitrogen in urea, so the two cannot be mixed. 2. Ammonium bicarbonate cannot be mixed with bacterial fertilizer When topdressing bacterial fertilizer in the soil, do not apply bacterial fertilizer and ammonium bicarbonate together, because ammonium bicarbonate will emit a certain concentration of ammonia gas, which has a certain toxic effect on the active bacteria in the bacterial fertilizer, and will make the bacterial fertilizer lose its fertilizer effect. 3. Acid fertilizer can't be combined Mixed use of alkaline fertilizers Spring crops are generally deficient in nitrogen. When topdressing nitrogen fertilizers, acidic fertilizers and alkaline fertilizers cannot be mixed. Once mixed, neutralization will occur, which will cause nitrogen loss and reduce fertilizer efficiency. After applying urea to the crop, it is impossible to water it immediately because the urine After being applied to the soil, the nutrients will be converted into amides. If you water them immediately, they will easily run off with the water. In addition, after applying urea, the method of covering soil can improve fertilizer efficiency. 5. Avoid using ammonium nitrate Pay more attention when applying ammonium nitrate. If you don't use it, you don't need to, because fruit trees absorb ammonium nitrate ions very easily. If you absorb too much, it will cause fruit tree poisoning. 6. Ammonium sulfate cannot be used for a long time Ammonium sulfate on the market is a physiologically acidic fertilizer. If it is applied on the same soil for a long time, it will increase the acidity of the soil and destroy the soil aggregate structure; if it is applied in alkaline soil, the ammonium ions of ammonium sulfate will be absorbed, and The acid root ions remaining in the soil react with calcium, which will make the soil harden and harden, which also has a great influence on the root activity.
