How to store unfinished fertilizer
How to store unfinished fertilizer? Fertilizer is an important and urgent material for agricultural production. In order not to miss the time, farmers’ friends have rushed to buy and store fertilizer. In order to reduce the loss of chemical fertilizer storage, here are some tips for farmers to pay attention to during the storage of fertilizers:
Studies have shown that: ammonium phosphate is placed in the open air, at a temperature of 16 ° C, the loss rate of nitrogen is: 3.4% for 1 day, 10.6% for 5 days, 18% for 10 days, 26% for 15 days, and 20 °C for 20 days. In the case of nitrogen loss rate: 8.8% for 1 day, 48% for 5 days, and 77% for 15 days; at a temperature of 32 °C, the loss rate of nitrogen is 18.9% for 1 day, 5 days. It is 67.9%, and 93.6% for 10 days.
It can be seen from the above data that the higher the ambient temperature, the greater the loss of nitrogen. Nitrogen fertilizers such as ammonium bicarbonate and ammonia water have poor stability. When the temperature exceeds 20 °C, they are easily decomposed into ammonia gas, carbon dioxide and water, which are gradually lost.
Therefore, it is best to buy more fertilizers, try not to have surplus, and summer should be more so. The stored fertilizer should be placed in a cool and dry room, and the temperature should be kept at 10-15 °C.
Fertilizers such as ammonium nitrate and calcium are extremely strong in temperature absorption. When the ground is wet when the air humidity is high, the ammonium nitrate will be lost, and the calcium will reduce the active ingredients. Moreover, ammonium nitrate will also absorb moisture and agglomerate, and explosion will occur when the human is broken. The method of moisture protection is: store in the warehouse as much as possible. If there is no warehouse, try to store it in the shed and frame, and pad the bottom pad, and protect it from moisture. Then cover it with plastic cloth or linoleum paper to prevent the suction from being fast and reduce. Fertilizer effect.

romatographic and use double-antibodyromatographic and use double-antibodysandwich method to detect antigen. Whenthe concentration of antigen in specimen ishigher than the minimum detection limit, theviral antigen will form complexes withlabeled antibodies first. Under chromatogra-phy, the complexes move forward along thenitrocellulose membrane till captured bypre-coated monoclonal antibody ofindetection zone.Through the visible color tointerprete the test results.
