Application of commodity organic fertilizer, improving quality and efficiency
First, the advantages of commodity organic fertilizer application
1, complete nutrition. Commodity organic fertilizer is rich in organic matter, which can provide crops with N, P, K, and various trace elements. After the crop is applied with commodity organic fertilizer, it can significantly improve the quality and yield of agricultural products.
2, improve the land. 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 adverse effects of soil salinity on crops, enhance crop resistance and pest resistance, and mitigate continuous cropping obstacles. .
Second, the number of commercial organic fertilizer applications
1, facilities, Fruits , Vegetables: watermelon, strawberries, peppers, tomatoes, cucumbers, etc., base fertilizer 300-500 kg per mu per quarter.
2, open sweet potatoes vegetables: watermelon, cucumber, potatoes, soybeans and onions and garlic, base fertilizer 300-400 kg per mu per quarter; cabbage and other leafy vegetables, base fertilizer 200-300 kg per mu per quarter; lotus seeds, basal acre per mu 500-750 kg.
3, food crops: wheat, rice, corn, etc., base fertilizer 200-250 kg per mu per quarter.
4, oil crops: rape, peanuts, soybeans, etc., base fertilizer 300-500 kg per mu per quarter.
5, fruit trees, tea, flowers, mulberry, etc.: According to the age of the tree, base fertilizer 500-750 kilograms per mu per quarter; new nursery stock base, 750-1000 kg per acre before the nursery.
6. For newly formed raw soil blocks, 750-1000 kilograms per acre will be added every year for 3-5 years before gradually increasing soil fertility.
Third, commodity organic fertilizer application notes and application methods
1. The long-term effectiveness of commodity organic fertilizers cannot substitute for the quick effects of chemical fertilizers. It must be applied according to different crops and soils and then combined with urea and formula fertilizers to achieve the best results.
2. Commodity organic fertilizer application method is generally based on the use of base (bottom) fertilizer. Before the crop is planted, the fertilizer is uniformly applied and ploughed into the soil. If the application is applied or applied, care should be taken to prevent the phenomenon of burning seedlings from occurring when the fertilizer is concentratedly applied. The application amount of the organic fertilizer should be determined according to the actual situation of the crop field.
3, when the organic fertilizer is used as top dressing, it must be filled with water in time.
4. When commodity organic fertilizers are used in dry season crops in high temperature seasons, they must pay attention to reducing the application amount and prevent the occurrence of burning seedlings.
5. The pH of commodity organic fertilizers is generally alkaline and PH should be noted for its adaptability and application amount.
UTZ Freeze dried coffee: also known as Freeze-dried Coffee, it is an Instant Coffee made by freezing liquid products and removing ice through sublimation.
The freeze-dried coffee chips retain the original flavor of coffee well. Due to its loose and porous internal structure and fast dissolution rate, it is a "instant coffee" that is convenient to measure and can easily control the concentration of the beverage.
