Produced by the organic fertilizer granulator machine is comprehensive in nutrition, contains nitrogen, phosphorus, potassium and trace elements, has long-lasting fertilizer effect, can improve the soil environment, and the application of organic fertilizer has an important effect on crop yield and quality. However, improper selection and use of organic fertilizers can also cause crop damage and yield reduction. Please pay attention to the following points when selecting and using organic fertilizers:
1. Pay attention to choose high-quality organic fertilizer
High-quality organic fertilizers are the basis for high-quality and high-yield crops such as vegetables and fruit trees. The quality of organic fertilizers used by farmers is uneven, and some are even mixed with urban sludge and domestic garbage. Even some of the chicken manures bought were mixed with mud, or were mixed with caustic soda by some unscrupulous traders (to increase the volume). After applying these inferior organic fertilizers to the soil, the effect can be expected. Therefore, high-quality organic fertilizers must be used in production. It is best to use regular large-scale factories when choosing commercial organic fertilizers.
2.Make sure to rot before applying
The current composting process still lacks the necessary maturity judgment standards and detection methods. In addition, the sources of organic fertilizers are complex and diverse. Therefore, for chicken manure and cow dung, which often carry germs, insect eggs and weed seeds, they are directly applied or piled. Incompletely roasted rot will adversely affect crop growth.
3.Strictly control the amount of fertilization
In general, organic fertilizer has a large volume and low nutrient content. It needs a large amount of application to meet the needs of crops, but not as much as possible. For example, it is advisable to apply 15-20 cubic meters of pure chicken manure and 35-40 cubic meters of decomposed soil and mixed fertilizer per acre per season. For eggplants and vegetables, the amount of fertilizer required is large, and the upper limit may be used; for leafy vegetables, the amount of fertilizer required is slightly smaller, and the lower limit may be used.
4.Organic and inorganic application
Organic fertilizers are full of nutrients, slow to release, and have long fertilizer effects. When crops need high fertilizer growth, they are often in short supply; while inorganic fertilizers are generally relatively simple in content, easily decomposed and absorbed by crops, but have insufficient stamina. Therefore, organic fertilizer and inorganic fertilizer must complement each other to complement each other.
5.Mainly Shiji and Shenshi
Organic fertilizers have long-lasting effects and slow nutrient release, and are generally applied as base fertilizers. In deep ploughing, the application of organic fertilizer is beneficial to the integration of soil and fertilizer and promotes the formation of soil aggregate structure, which can effectively improve the physical and chemical properties of soil and increase soil permeability.
6.Good effect with the application of biological fertilizer
Whether organic fertilizer is applied basally or flushed, it is best to use bio-fertilizer. The biological bacteria in the biological fertilizer can accelerate the decomposition of the organic matter in the organic fertilizer, making it more conducive to crop absorption, and at the same time can decompose and transform some harmful substances in the organic fertilizer to avoid damage to the crop. Generally, when organic fertilizer is applied at the base, 150-200kg of bio-fertilizer can be applied per acre, and 20-25kg per acre can be applied for topdressing.
