First, the advantages of commercial organic fertilizer application
1. Complete nutrients. Commercial organic fertilizer is rich in organic matter, which can provide crops with nitrogen, phosphorus, potassium and various medium and trace elements. After applying commercial organic fertilizers, the quality and yield of agricultural products can be significantly improved.
2. Improve the ground force. The application of commercial organic fertilizer can improve soil physical and chemical properties, enhance soil permeability, water retention and fertilizer retention, prevent soil compaction and acidification, significantly reduce the adverse effects of soil salinity on crops, enhance crop resilience and resistance to pests and diseases, and alleviate continuous cropping obstacles. .
Second, the amount of commercial organic fertilizer application
1. Facility fruits and vegetables: watermelon, strawberry, pepper, tomato, cucumber, etc., base fertilizer 300-500 kg per mu per season.
2, open vegetables: watermelon, cucumber, potatoes, edamame and onion garlic, base fertilizer per season 300-400 kg per mu; vegetables and other leafy vegetables, base fertilizer per season 200-300 kg per acre; lotus seeds, base fertilizer per acre 500-750 kg.
3, food crops: wheat, rice, corn, etc., base fertilizer 200-250 kg per mu per season.
4, oil crops: rapeseed, peanuts, soybeans, etc., base fertilizer per season 300-500 kg per mu.
5, fruit trees, tea, flowers, mulberry trees, etc.: According to the age of the tree, the base fertilizer is 500-750 kg per mu per season; the new seedling base is 750-1000 kg per acre before the nursery.
6. For the newly leveled raw soil field, 750-1000 kg per mu per year will be applied in 3-5 years to gradually restore soil fertility.
Third, the application of commercial organic fertilizers and application methods
1. The long-term effect of commercial organic fertilizer can not replace the quick-acting effect of chemical fertilizer. It must be applied according to different crops and soils, combined with urea and formula fertilizer, in order to obtain the best results.
2. The application method of commercial organic fertilizer is generally based on the use of base (bottom) fertilizer. The fertilizer is evenly applied and ploughed into the soil before the crop is planted. If the application of strips or furrows is adopted, care should be taken to prevent the occurrence of burning of the fertilizers in a concentrated manner. The amount of commercial organic fertilizer applied should be determined according to the actual situation of the crop field.
3, when the commercial organic fertilizer is used as top dressing, it must be poured in time.
4. When commercial organic fertilizer is used on dryland crops in high temperature season, it is necessary to pay attention to appropriately reduce the application amount to prevent the occurrence of burning seedlings.
5. The pH of commercial organic fertilizer is generally alkaline. Pay attention to its adaptability and application rate on the use of acid-friendly crops.
