The use of compound fertilizer in the production of fruit trees is a unified formula fertilization, but it still fails to adopt different formula fertilization according to the type and quantity of fertilizer needed for a certain fruit tree and soil fertility and the lack of nutrient elements in the soil. Fertilization is still not reasonable enough Not science. Cultivation of fruit trees, soil testing formula balanced fertilization, fruit tree science fertilization and further development of the fruit industry to increase production and efficiency, can make farmers continue to increase income. Soil testing formulation Balanced fertilization is based on the analysis of soil nutrients, based on the needs of the fruit tree output and the ability of the soil to supply nutrients, determine the amount, time and method of applying organic fertilizer and inorganic fertilizer, and maintain the balance of soil nutrient ratio science Fertilization method. The balanced fertilization of the fruit tree formula is based on the scientific determination of nutrients contained in the orchard soil and fruit tree leaves. Under the premise of planning to achieve the expected yield, according to the needs of fruit tree growth and development, what nutrients should be supplemented according to the lack of nutritional elements? The principle of lacking much to supplement is to determine the types and quantities of fertilizers to be applied reasonably, to achieve nutrient balance in the tree body, and to achieve the best economic benefits of fruit tree production. The application of soil testing formula for balanced fertilization in fruit trees requires soil samples taken from selected sites to be analyzed for available nutrient content in the soil. According to the predetermined yield, nutrients lack any nutrients, and the principle of lacking much is added. The fertilization formula is proposed. Formulated fertilization. Fruit tree balance soil fertility pay attention to matters: 1. Fruit trees absorb nutrients from relatively fixed soil. Therefore, it is necessary to quantitatively replenish nutrients due to trees. The type of supplemental nutrients and the amount of supplements should be based on the current nutrient content in the soil, what is missing from the soil, but what the tree needs for nutrients and planned production. 2. The ratio between nutrient elements has an effect on the growth of fruit trees and there are antagonistic effects between nutrient elements. If the amount of nutrient elements is relatively large and the ratio is imbalanced, the nutrient elements can often not be fully utilized, resulting in the waste of a certain nutrient element or the occurrence of a deficiency syndrome. Pay attention to the proportion of various nutrients when fertilizing. 3. Pay attention to the effect of soil factors on the use of nutrient elements. Because of the soil environment, it includes organic matter and pH. Organic matter can play a role in improving the soil, balancing elements, and increasing fertility. PH value is the main factor affecting the effectiveness of mineral nutrients. 4. Pay attention to the input of organic fertilizer. Every gram of orchard base fertilizer should be applied at least 5,000 kg of high-quality farmyard fertilizer, which should be mixed with phosphate fertilizer and used after fermentation. Can also be taken to shred straw, wheat straw and other objects to cover, or a kind of clover and other green manure plants, through the measures of mowing and pressing, increase soil organic matter content, and enhance the soil to maintain fertilizer and water storage capacity. 5. Fertilize according to the soil nutrient value and according to the growth potential of the tree. For excessive growth of trees, control the amount of nitrogen fertilizer; for the trees with weaker growth, the amount of nitrogen fertilizer should be increased; for orchards with low potassium, the proportion of potassium fertilizer should be increased; for orchards with low phosphorus content, the amount of phosphate fertilizer should be increased appropriately. . 6. Pay attention to the fertilization area and fertilization depth. The soil fertilization should not be too close to the trunk. The absorption roots of the trees around the trunk are less. The applied fertilizer is not easy to be absorbed by the tree and it is easy to burn roots and cause fertilizer damage. The depth of fertilization should be 30-40 cm deep in autumn and not more than 20 cm in summer.
