Fertilizer Fertilizer Fertilizer Fertilizer equipment Henan Viet equipment manufacturing R & D equipment and silicon and silicon fertilizer varieties are citrate soluble silicon fertilizer, water soluble silicon fertilizer into two categories, citrate soluble silicon fertilizer means insoluble in water and soluble in acid After Silicon can be absorbed by plants, the target tooth turning machines, mostly common scrap steel mill slag, fly ash, ore processed at high temperature calcination process, the general administration of a large amount (25 per acre -50 kg), suitable for basal application, refers to a water-soluble silicon fertilizer dissolved in water can be directly absorbed by the plant and silicon, crops absorb its high efficiency, high temperature chemical synthesis, the target tooth turning machines prices, production process is relatively complex and costly, but less fertilizer, commonly used as a foliar spray and drip irrigation flushes, but also for base facilities and dressing, the specific amount of crop varieties according hi silicon cases, local as well as the lack of silicon and silicon content of the soil and the concrete set. "NPK + silicon" scientific balanced fertilization, in order to achieve high yield and quality results. Silicon can change the crop quality characteristics, the target tooth turning machine technology, is attracting worldwide Dohi academic and plant nutrition academic attention. Zinc fertilizer fertilizer equipment fertilizer equipment Henan Viet zinc fertilizer company can develop zinc fertilizer basal application of zinc fertilizer fertilizer equipment, dressing, seed soaking, seed dressing, spraying foliar spraying general do best. How to correctly use zinc fertilizer in Henan Shing Engineering Technology experts concluded methods include the following: 1 and Zn applied on zinc too sensitive crops, such as corn, rice, peanuts, soybeans, sugar beets, beans, fruit, tomatoes, etc. Chemical Zinc better. 2, applied on zinc deficiency in soil: Chemical Zinc deficiency in the soil better, no deficiency in the soil without application of zinc fertilizer. If earlier the plant showed symptoms of zinc deficiency, it may be early spring temperatures low, microbial activity is weak, fertilizer is not completely dissolved, seedling roots activity weak, poor absorption; phosphorus - antagonism zinc fertilizer target tooth turning machines, soil environment effects may zinc deficiency. But the late temperatures, this symptom disappeared. 3, base fertilizer applied every other year: zinc fertilizer base fertilizer hectare zinc sulfate is about 20-25 kg, evenly applied, while next year administration, because the longer zinc fertilizers in the soil Vinca, need not be administered annually.
