Recently, when the author went to the countryside, he discovered that some farmers did not understand the performance of chemical fertilizers and mixed chemical fertilizers blindly, causing some overwintering vegetables to suffer from fertilizer damage and causing unnecessary losses. Now let's explain to the farmer friends which chemical fertilizers cannot be mixed so that they can be used reasonably in production. 1, superphosphate can not be mixed with grass ash, lime nitrogen, lime and other alkaline fertilizers. Because calcium superphosphate contains free acid, which is acidic, and the alkaline fertilizer contains more calcium, if the two are mixed, it will cause acid-base reaction, reduce the fertilizer efficiency, and it will cause calcium to fix the phosphorus, resulting in "two loses." . 2, alkaline fertilizers such as calcium magnesium phosphate fertilizer can not be mixed with ammonium ammonia fertilizer. Because alkaline fertilizers and ammonium nitrogen fertilizers such as ammonium sulfate, ammonium bicarbonate, ammonium chloride, etc., will lead to and increase the volatilization loss of ammonia and reduce fertilizer efficiency. 3, manure, urine and other farmyard fertilizer can not be mixed with calcium, magnesium phosphate fertilizer, grass ash, lime and other alkaline fertilizers. Because the main component of human and animal urine is nitrogen, if it is mixed with alkaline fertilizer, it will neutralize and fail. 4, chemical fertilizer can not be mixed with rhizobia fertilizer and other bacterial fertilizers. Because chemical fertilizers are more corrosive, volatile, and absorbent, if used in combination with bacterial fertilizers, they will kill or inhibit live bacteria and render the fertilizer useless. 5, ammonia can not be mixed with human excreta, plant ash, potash, ammonium phosphate, potassium chloride, urea, ammonium bicarbonate and other mix. Ammonium bicarbonate must not be mixed with plant ash, human waste, and potash nitrogen. Ammonium sulfate can not be mixed with plant ash and ammonium bicarbonate. Ammonium nitrate cannot be mixed with grass ash, ammonia, etc. If the fertilizers mentioned above are mixed and applied, they will cause acid-base reactions and reduce the fertilizer efficiency. 6, phosphate rock, bone powder and other insoluble phosphate fertilizer can not be mixed with grass ash, lime ammonia, lime and other alkaline fertilizers. Otherwise it will neutralize the organic acids in the soil, making insoluble phosphate fertilizer more difficult to dissolve, vegetables can not absorb and use. 7. Unripe farmyard fertilizers cannot be mixed with ammonium nitrate. Because unfamiliar farmyard manure can only be absorbed and utilized by crops after decomposition and rot, if it is mixed with ammonium nitrate, unripe farmyard manure will be lost in the decomposition process, so it cannot be applied, otherwise both nitrogen will suffer. Loss, reduce fertilizer efficiency. Our pp foil combined cap is widely used in the hospital and clinical infusion issue.The main working procedures such as injection molding, assembly, inspection, inner packing and outer packing will go under a series of regular management system. During the whole procedures,firstly, we use the injection molding machinery to form a cap with a hole in its head,then we will embed a gasket into the hole and then use a pressing slice to fix the cap and the gasket, at last, we will seal the combined cap with a suitable film on it. We will check the sealing ability to prevent the leakage in application before we ship the cargo. If you are interested in our this type product, your detailed inquiries will be great.
