Fruit tree soil testing formula balanced fertilization six attention
Balanced fertilization of fruit tree soil testing formula is of great significance for satisfying the demand of fruit trees for various elemental fertilizers. It is an important fertilization method to reduce the occurrence of fruit tree deficiency and ensure the comprehensive nutrition of fruit trees. On March 12th, an agronomist from the soil testing and fertilization station in Baoji City, Shaanxi Province, said in an interview with reporters that the majority of fruit farmers should pay attention to the following six points when conducting balanced fertilization of fruit trees? 1. Fruit trees absorb nutrients from relatively fixed soil. Therefore, it is necessary to quantitatively supplement nutrients due to the tree. The type of supplemental nutrients and the amount of supplements should be based on the amount of nutrients available in the soil, the nutrients that are missing in the soil and the tree needs, and the planned yield. 2. There is an antagonistic effect between nutrients, so the ratio between nutrients has an effect on the growth of fruit trees. If the amount of nutrients is relatively large and the proportion is out of balance, nutrients are often not fully utilized, causing a certain nutrient element to be wasted or suffering from deficiency, and the proportion of various nutrients should be paid attention to when fertilizing. 3. Pay attention to the influence of soil factors on the utilization of nutrients. Soil environmental factors include organic matter, pH and so on. Organic matter can play a role in improving soil, balancing elements, and increasing fertility. The pH value is the main factor affecting the effectiveness of mineral nutrients. 4. Pay attention to the input of organic fertilizer. At least 5000 kg of high-quality farmyard manure should be applied to the base fertilizer of each acre orchard. It can also be covered with chopped straw, wheat straw, etc., or green-crop plants such as clover, which can increase soil organic matter content and enhance soil fertility and water storage capacity through measures of cutting and pressing. 5. According to the measured value of soil nutrients, fertilize according to the growth potential of the tree. For the growth of excessive trees, control the amount of nitrogen fertilizer; for the growth of weak trees, increase the amount of nitrogen fertilizer; for the orchard lacking potassium, increase the proportion of potassium fertilizer; for orchards with low available phosphorus, increase the amount of phosphate fertilizer. . 6. Pay attention to the area of ​​fertilization and the depth of fertilization. Soil fertilization should not be too close to the trunk. The tree around the trunk has less absorption roots. The applied fertilizer is not easily absorbed by the tree and easily burned, causing fat damage. The depth of fertilization is 30-40 cm in the autumn and not more than 20 cm in the summer.
