During the mixing process or during the application of the fertilizer, due to the different composition of various fertilizers, some fertilizers will undergo a series of chemical reactions after mixing, resulting in loss of nutrients or decreased effectiveness of nutrients. Fertilizers belonging to this situation, mutual Can not be mixed. Some fertilizers, although mixed, will not cause chemical changes, but will cause physical changes, making the fertilization process difficult. If two fertilizers with higher hygroscopicity are mixed, the mixture is more hygroscopic. For example, a mixture of ammonium nitrate and urea has a hygroscopic critical relative humidity of only 18% , and the hygroscopicity is greatly improved. Therefore, the two should not be mixed. If urea and superphosphate are mixed, although the time for conversion of urea to ammonium can be prolonged, the crystal water contained in the superphosphate will be freed, which will increase the humidity of the fertilizer, easily agglomerate, and cause difficulty in fertilization. With the application.

 

Sulfur can promote flower growth

 

In the planting of flowers and trees, a certain amount of sulfur powder is applied in the slab, saline soil garden or flower pot, which can adjust the pH value, reduce the salt and alkali damage, prevent rotten root and nutrient deficiency, and promote the normal growth and development of flowers and trees. After the grafting is completed, the sulphur powder is sprayed on the interface after grafting the multi-slurry plants such as cactus to prevent the interface from decaying. After turning the pots and changing the soil, after cutting off the rotten roots, applying sulfur powder on the wounds can promote new roots and accelerate the growth of flowers and trees; inserting antisepsis, camellia, rhododendron and other flowers and trees cutting seedlings, cutting and cutting, on the base After cutting with sulfur powder, it can effectively prevent the cuttings from decaying, promote the formation of callus, greatly improve the survival rate and promote growth. Sulfur powder on the base of the flower arrangement can inhibit the decay of the incision cortex and prolong the fresh-keeping period of the flower arrangement; control the disease, spray the sulphur powder on the flower-tree with powdery mildew, when the leaf surface is wet, spray with sulfur powder suspension in dry weather, and control the white powder Disease, rust, etc. have special effects.
