The content of soil organic matter decreases, fertility decreases, and the living space of beneficial microorganisms in the soil becomes smaller and the number decreases. The disease resistance, cold resistance, drought resistance and lodging resistance of crops are weakened. How to break through this predicament, that is, rational fertilization. Through the scientific combination of four types of fertilizers (organic fertilizer, macro-element fertilizer, biological bacterial fertilizer, medium and trace element fertilizer), the nutrient supply of fruit trees can be achieved to ensure that the root system of crops can obtain comprehensive and sufficient nutrients.
Characteristics and Precautions of Four Fertilizers
1. Organic fertilizer (organic fertilizer production process). Organic fertilizer is of great significance in improving fruit quality. After the organic fertilizer is applied to the soil, the organic matter can effectively improve the physical and chemical conditions of the soil, ripen the soil, enhance the ability of the soil to retain and supply fertilizer and buffer, and create good soil conditions for the growth of fruit trees.
2. A large number of element fertilizers (npk fertilizer production line). Nitrogen, phosphorus and potassium are the three essential elements for fruit trees. The application of these three elements has been widely recognized and accepted by the majority of fruit farmers, and has played an important role in improving fruit yield. It should be pointed out that a large number of elements not only refer to nitrogen, phosphorus, potassium, but also carbon, hydrogen, and oxygen. These three elements are also very important. They are obtained from air and water respectively. They must be ventilated and light, and watering should be In time, pay attention to maintaining the proper moisture content of the soil.
3. Biological bacterial fertilizer (bio organic fertilizer production). At present, there are many types of biological bacterial fertilizers. The main ones that have good effects on fruit trees are the beneficial bacteria that dissolve phosphorus, potassium, and accelerate decomposing, and can enhance the decomposition ability of organic matter and soil permeability.
4. Medium and trace element fertilizer (fertilizer production line). Medium elements refer to silicon, calcium, magnesium, and sulfur, and their effects on fruit trees are second only to macroelements. Studies in recent years have shown that medium elements play an important role in improving tree resistance and fruit quality.
