The role and methods of application of bioorganic fertilizers
Bioorganic Fertilizer It contains organic matter and microflora useful for crops, and also contains a certain amount of nitrogen, phosphorus, potassium nutrients and other elements. According to the standard biological organic fertilizer, the organic matter content is more than 40%, the number of live bacteria beneficial to crops is more than 20 million per gram, the content of nitrogen, phosphorus, potassium and other useful elements is more than 5%.
Raw materials of organic matter come from animal excrement, attached cadavers, plant straw, processed bran byproducts, rotten soil, household waste, etc. D. Untreated urban household waste cannot be used as fertilizers for grains, oil, fruits, vegetables and food crops related to people's lives. Increasing the application of organic fertilizers can weaken and improve the soil, improve fertility, provide nutrients for crops and promote sustainable agricultural development.
Useful biological bacteria include nitrogen-fixing bacteria that can fix free nitrogen in the air, phosphate bacteria that decompose phosphorus-potassium fertilizers, potassium bacteria, enzyme bacteria that decompose organic matter, and radioactive bacteria that can destroy harmful microorganisms, bacteria, declicercidic bacteria, etc. D., Can use fertilizer to treat, to destroy and treat diseases, to improve immunity, protect the crop for healthy growth. Thus, bioorganic fertilizers are the leading development direction for sustainable agricultural development and fertilization in the future.
Biological organic fertilizers should be used in combination with nitrogen fertilizers and complex fertilizers. They must be used in a ditch and covered with soil after application to prevent exposure to sunlight. Ultraviolet rays kill beneficial bacteria. When the soil is dry, water should be poured so that biological bacteria can reproduce normally. In addition, biological organic fertilizers cannot be used simultaneously with fungicides.
Biological organic fertilizers have a slow effect and long-lasting fertilizer effect. It is mainly used as the main fertilizer in sugar orange. It is used as a strong fruit fertilizer and fruit fertilizer on autumn shoots. It is used in 150-200 kg per acre. It is mixed with 10-15 kg/mu, covered with soil for protection from the sun, moisturizes and improves efficiency.
