When will amines be fertilized?
Carbon is the most commonly used varieties of amine fertilizer, with nitrogen and phosphorus fertilizer, fertilizer use, fertilizer is generally 120 days or so, the suitable conditions of temperature, moisture in the next 50 days after applying fertilizer best.Carbon amine is a white compound that is granular, plate-like or columnar crystalline. Because ammonium bicarbonate is a carbonate, it must not be placed with acids because the acid reacts with ammonium bicarbonate to form carbon dioxide, which causes ammonium carbonate to go bad. However, in the rural areas, ammonium carbonate and acid reaction are also used. The ammonium bicarbonate is placed in the vegetable greenhouse, and the greenhouse is sealed, and ammonium bicarbonate is placed at the top, adding hydrochloric acid. At this point, the amines react with hydrochloric acid to produce ammonium chloride, water, and carbon dioxide. Carbon dioxide can promote plant photosynthesis, increase vegetable production, and the resulting ammonium chloride can also be used as fertilizer again. Ammonium bicarbonate in the chemical formula of ammonium ion, is an ammonium salt, and ammonium salt and alkali can not be put together, so ammonium bicarbonate and sodium hydroxide or calcium hydroxide should not be put together
Rain does not applyAttention should be paid to the following problems in the application of ammonium bicarbonate:(1) ammonium bicarbonate can not be mixed with alkaline fertilizer in order to prevent ammonia volatilization and cause nitrogen losses.(2) to achieve the "five not": that is not mixed with fine soil without nitrogen, and there was dew without nitrogen, rain without nitrogen, Tian no inch of water without nitrogen, the sun does not apply. If fertilization time was sufficient, it is best able to make deep application of ammonium bicarbonate fertilizer or fertilizer ball. In addition, ammonium bicarbonate in transportation and storage, light light, close packed, stored in a cool dry place, not with the basic fertilizer and human excrement mixed, so as to avoid loss of effective fertilizer.(3) do not contact crops, seeds, roots, stems and leaves, so as not to burn the plants.(4) do not do fertilizer, otherwise it may affect the germination of seeds.(5): bogey and mixed fertilizer after application of ammonium bicarbonate will release ammonia, fertilizer and fertilizer will make contact, bacteria in the death of the fertilizer losing effect.(6) avoid spraying: spraying ammonium bicarbonate are easy to be burnt leaf, affecting crop photosynthesis
Avoid high temperature applications. The temperature is below 20 DEG C when ammonium bicarbonate is relatively stable, high temperature or moisture in the product exceeds a certain standard, is easy to be decomposed into ammonia and carbon dioxide emissions in the air, causing loss of nitrogen fertilizer. According to the test results show that the winter crops better than urea and ammonium carbonate. Because the temperature is low in winter, the process of urea conversion is long, but the ammonium carbonate can be directly absorbed without conversion. It is beneficial to the early growth and fast growth of winter crops. In addition, when applied to the soil ammonium bicarbonate, ammonium ion dissociation can be directly by soil colloid adsorption, and urea to winter crop soil, urea was dissolved in the soil solution in the molecular state, but not by soil colloid adsorption, it is more likely to cause the loss of nutrientsThe use of ammonium bicarbonate does not mix with alkaline fertilizers, which can lead to loss of nitrogen nutrients, resulting in low fertilizer efficiency. Using ammonium hydrogen carbonate friends should know that not with urea and ammonium hydrogen carbonate mixed fertilizer, ammonium bicarbonate if mixed with urea, urea conversion rate will not only extend, and will accelerate the volatilization of urea.Ammonium bicarbonate extremely volatile, so to avoid the ground using ammonium bicarbonate, ammonium bicarbonate has strong corrosion on leaf blade, easy to burn, can not be used as a foliar spray. There is one thing to note is that if the soil drought, even deep application coverage, can not be dissolved in ammonium bicarbonate, better soil moisture using ammonium bicarbonate, can reduce the volatilization loss, improve efficiency
