4mm NPK粒化肥的

4mm Granular NPK Fertilizer Composition The effect of organic and inorganic compoundfertilizers: Nutrient-rich comprehensive fertilizer with economic priorities, fertilizer not only fast, fertilizer and long. Organic and inorganic fertilizers to organic fertilizers as the main raw material, through a scientific formula, add the crops needed for large, medium and trace elements, set Bioavailability of inorganic fertilizer and organic fertilizer in one of slow, fertilizer utilization rate of 95% above. The fertilizer can promote root development, robust growth, enhance the capacity of nutrient uptake, enhance photosynthesis, reduce the maturity of crops, improve crop resistance to disease, cold, drought resistant cropping ability, to increase yield. Play fertilizer caused Alleviation of soil compaction, rapid restoration of land to promote the plants to absorb the undigested part of the original fertilizer. Bio-organic and inorganic fertilizers have played a role in the gradual replacement of chemical fertilizers, and greatly reduced the toxic chemical residues and heavy metal residue and restore the original ecological cultivation, served to protect the human environment, the positive effect of restoration of land. (Including fruits and specialty fertilizer, tuber-specific fertilizer), the main features are as follows: (1) nutrient complete, mustering the crop growth period of growth and development needs. (2) biological, organic and inorganic combination, can improve nutrient utilization, with the phone bill had rapid, long-acting organic fertilizer, as well as a variety of biological effects, to avoid large quantities of organic fertilizers and nutrient deficiencies caused by a single application of chemical fertilizer pollution problems, may reduce the number of times or to achieve a one-time fertilization. (3) improvement of crop quality, reduce nitrate, amino acid salt content. (4) to improve the soil tax, retirement and breathable performance. (5) effectively reduce the pollution of heavy metals on soil and crops poisoned. Organic inorganic compound fertilizer application methods: The organic - inorganic fertilizer can do basic fertilizer, seed and top dressing fertilizer, basal to do better. Applied to field crops, such as rice, wheat, corn, soybeans. Basal or the kind of fertilizer usage, mu recommend applying 50-80 kg, combined with soil preparation or planting use. Fertilizer should be made sooner fertilizer is recommended mu 20-50 kg, before rainfall or irrigation prior to spreading on the main pole outside the 15 cm range. Scope: Widely used in food crops and cash crops, can be used for vegetables, fruit trees, flowers, nursery stock, tobacco, oil, tea, herbs, rice, wheat, corn, cotton and other crops in the basal. Storage conditions: Should pile up in a dry ventilated shade and avoid direct exposure to high temperature and humidity and sunlight. Note: Applicator should be as even as possible application of large dosage of hours, the proposed focus on planting hole, but should avoid direct contact with seeds
