Winter and spring ammonium bicarbonate technology

It is advisable to apply deep soil and paddy fields to the soil for about 10cm in deep application. The fruit trees should be applied 15-20cm deep. In addition, the soil should be covered immediately after deep application. Mix or mix the ammonium bicarbonate and dry fine soil in a ratio of 1:2-3, mix well and put it into a plastic bag, apply it after 24 hours of sealing, and use the adsorption of fine soil to reduce the volatilization of nitrogen fertilizer. Loss can improve fertilizer efficiency; if conditions permit, ammonium bicarbonate and superphosphate can be mixed in a ratio of 3-4:1, but when mixing, please note: 1 Do not put it with long-term application. 2 Ammonium bicarbonate should not be mixed with alkaline fertilizers such as grass ash, lime, calcium magnesium phosphate fertilizer, fly ash, etc., and should be staggered for 3-4 days when applied separately. The application of ammonium bicarbonate in an appropriate amount is generally about 25 kg per acre. The timely application of ammonium bicarbonate as a base fertilizer in the early rice breeding process in the double-season rice area must be applied 5 days before sowing. In addition, according to the habit of carbon ammonium "water", fertilization should be carried out best after rainy days in the appropriate period, such as drought and soil shortage, it is best to water in time.
