Reasonable fertilization

1. The main organic fertilizer, supplemented by chemical fertilizers. Use manure, cake, manure, compost, manure, etc., as well as factory-processed high-quality organic fertilizers, such as expanded chicken manure, microbial fertilizers, organic foliage fertilizer and so on. Formula fertilization based on soil fertility and crop nutrient requirements.
2. Apply basal fertilizer and reasonably apply fertilizer. In the fertilization mode where organic manure is dominant, 70% or more of the total manure that is dominated by organic manure is used as the base fertilizer. Fertilizer applied to soil before planting is not easy to lose, and soil properties can be improved and soil fertility can be improved. According to crop growth and demand, top dressing is based on available fertilizers. Root zone applicator, ditch application, acupoint application, drench fertilizer and foliar spray and other methods.
3. Scientific matching, balanced fertilization. Fertilization should be based on soil conditions, crop nutrient needs and seasonal climate changes and other factors, adjust the ratio and amount of various nutrients, to ensure that the proportion of nutrients needed for balanced supply of crops. In addition to organic fertilizers and chemical fertilizers, nutrient solutions such as microbial fertilizers, trace element fertilizers, and amino acids can be used as nutritional supplements for crops through root application or foliar spray.
4. Note the chemical reactions and antagonism between the nutrients. Phosphate phosphate ions react with calcium ions very easily, resulting in insoluble calcium phosphate, resulting in plants can not absorb, there is a lack of phosphorus. Iron, aluminum, and calcium ions in the red soils of southern China will form insoluble phosphates with phosphates. Phosphate fertilizers such as superphosphate cannot be directly applied to the soil. They must be mixed with organic fertilizers and then mixed and then applied. Phosphate fertilizers should not be mixed with lime and should not be mixed with fertilizers such as calcium nitrate. Potassium ions and calcium ions antagonize each other. Excessive potassium ions will affect the absorption of calcium by crops. On the contrary, too much calcium ions will affect the absorption of potassium ions by crops.
5. Prohibit and limit the use of fertilizer. Municipal solid waste, sludge, waste from urban and rural industries, and organic fertilizers that have not been harmlessly treated do not meet the corresponding standards for inorganic fertilizers. Chlorine-free crops are prohibited from using chlorine-containing fertilizers.

Grinding Cylpebs

Grinding Cylpebs usage and production both like the cast iron balls, just the shape difference. Production method like the cast grinding balls, also manufactured by melting and mould. Production process is: Raw material chemical composition and optional proportion-- Melting and pouring-- Oil quenching-- Temper-- Polishing
