Superphosphate is a cheap chemical phosphate fertilizer commonly used in agricultural production, and its main components are calcium phosphate and calcium dihydrogen phosphate. Calcium phosphate is hardly soluble in water and it is difficult to exert fertilizer efficiency. It is a calcium dihydrogen phosphate that does not contain much calcium phosphate in the superphosphate. However, one of the biggest disadvantages of calcium dihydrogen phosphate is that it easily combines with certain inorganic elements in the soil to form insoluble substances and loses fertilizer efficiency. Organic fertilizers can effectively overcome this shortcoming, and can also gradually convert calcium phosphate, which is poorly soluble in water, into soluble. Therefore, the combination of superphosphate and organic fertilizer can greatly improve the fertilizer efficiency.
The specific method is: crushing and sieving the superphosphate, taking the powder and mixing with pig manure, chicken manure, beef and sheep manure, manure, straw powder, etc. in a ratio of about 1:4, and after fully fermenting, take agglomerate Into the pre-excavated cave ditch to make the base fertilizer, and then fill the soil to grow crops. The amount of application depends on the need. This method has the following advantages:
1. It can reduce the contact between superphosphate and soil, effectively avoiding soluble phosphorus to become insoluble matter and reducing fertilizer efficiency.
2. The superphosphate and organic fertilizer are mixed into the soil to form loose agglomerates. The water is easy to infiltrate and dissolve the soluble phosphorus. The plant roots also easily penetrate into the mass to absorb the phosphorus dissolved in water. Moreover, the root acid and organic fertilizer secreted by the root tip of the plant simultaneously act on the insoluble calcium phosphate, and the calcium phosphate is gradually dissolved to further increase the utilization of phosphorus in the superphosphate.
3, superphosphate and organic fertilizer mixed application, also changed to a single fertilization for compound fertilization, increased the types of elements applied to plants, but also promote the absorption and utilization of phosphorus by plants, and better meet the nutritional needs of crops.
4. After the superphosphate and organic fertilizer are mixed into the soil, it can overcome the disadvantages of the normal phosphorus and the phosphorus concentration in the soil, affecting the normal life and activities of the microorganisms in the soil, inhibiting the absorption of nutrients by the plant, and protecting The activity of the soil also increases the efficiency of plant absorption of nutrients.
In addition, production practice has proved that the current application of iron, zinc, manganese and Other trace element fertilizers and organic fertilizers after fermentation and fermentation will greatly improve their fertilizer efficiency.
