2, avoid dry soil application. The soil is dry, even if it is covered, the fertilizer can not be dissolved and absorbed in time.
Absorption and utilization of materials. Only when the soil has a certain humidity, the application of ammonium bicarbonate can get the fertilizer in time.
Dissolve to reduce the loss of volatilization.
3, avoid high temperature application. The volatility of ammonium bicarbonate is closely related to the temperature. The higher the temperature, the stronger the volatilization.
Therefore, ammonium bicarbonate should not be applied under high temperature and hot days.
4, avoid mixed with alkaline fertilizer. Ammonium bicarbonate if mixed with alkaline ash, lime, etc., or
Simultaneous application with them will lead to more volatile nitrogen loss and loss of fertilizer efficiency, so ammonium bicarbonate should be applied alone.
5, avoid mixing with bacterial fertilizer. After the application of ammonium bicarbonate, a certain concentration of ammonia gas will be emitted. If it is in contact with the bacterial fertilizer, it will
The living bacteria in the bacterial fertilizer are killed, and the effect of increasing the productivity of the bacterial fertilizer is lost.
6, avoid mixing with superphosphate and use overnight. Ammonium hydrogen phosphate mixed with superphosphate, although
The effect is good, but it should not be placed for a long time after mixing, and it is not possible to stay overnight. Because of the increased hygroscopicity of superphosphate, it will make the fertilizer
The material becomes slurried or agglomerated and cannot be used.
7, bogey and mixed with urea. Crop roots cannot directly absorb urea, only under the action of urease in the soil.
After being converted into ammonium nitrogen, it can be absorbed and utilized by the crop; after the ammonium hydrogen phosphate is applied to the soil, the soil solution is acidified for a short period of time.
The sexual reaction will accelerate the loss of nitrogen in the urea, so ammonium bicarbonate cannot be mixed with urea.
8, avoid mixing with pesticides. Ammonium bicarbonate and pesticides are chemical substances that are highly susceptible to moisture hydrolysis. Have
Many pesticides are alkaline, and they are easy to produce chemical reactions, which reduce fertilizer efficiency and efficacy.
9, bogey and use of fertilizer. Ammonium bicarbonate is highly irritating and corrosive, and ammonia gas is emitted when it is decomposed.
After contact with the seeds, it will spoil the seeds and even burn the embryos, affecting germination and emergence. According to the test, 12.5 per acre
Kilogram of ammonium bicarbonate is applied as wheat seed fertilizer, and the emergence rate is less than 40%; for example, ammonium bicarbonate is applied to rice field
On, then sow, the rate of rotten buds is more than 50%.
10, avoid topsoil application. According to the measurement, when the temperature is 29 ° C, the ammonium bicarbonate applied to the topsoil, 12 hours loss
Nitrogen is 8.9%, while deep application of 10 cm of cover soil, less than 1% of nitrogen loss in 12 hours. In rice fields, bicarbonate
The equivalent of nitrogen per kilogram can increase the yield of rice by 10.6 kilograms, and the deep application of increased yield of rice by 17.5 kilograms. Therefore, carbon is applied
Ammonium hydrogen phosphate is used as the base fertilizer. In the dry land, it should be ditched or nested for 7-10 cm, and the soil should be drenched while applying soil;
It is advisable to apply side plows and plow the plows to make the fertilizer into the mud and improve the utilization rate.
