Fruit tree fertilization precautions

The growth and development of fruit trees are inseparable from fertilizer, and all kinds of fruit trees have their own development rules and growth laws. How to fertilize according to the law of fruit tree growth and development is the key to achieve high yield. But some fruit growers often have all kinds of problems because of improper fertilization. Let's take a look at the matters needing attention in fruit tree fertilization with Xiaobian.

1. Blind fertilization

The growth and development of fruit trees has its natural law, such as spring hair, summer growth, autumn harvest and winter storage, such as the absorption and storage of nutrients and trees, wood, flower buds and roots from September to November before winter, for flowering and fruiting in the coming spring, while many fruit growers do not water and fertilize for a long time, affecting the storage of nutrients and production in the coming year. In the planting management, according to our own feeling group, we should not irrigate or not apply when we should water and fertilize, and indiscriminately when we should not water and fertilize, which will lead to the imbalance of reproductive growth and vegetative growth of fruit trees, resulting in vigorous growth of branches and leaves and virtual growth of trees. resulting in a large number of physiological fruit drop phenomenon.

2. Single fertilization

In order to facilitate the knowledge of fertilization for fruit trees due to lack of water, many fruit growers apply nitrogen, phosphorus and potassium compound fertilizer or organic fertilizer only when fertilizing. this will lead to the lack of calcium, magnesium, sulfur, boron, silicon, iron, zinc and other elements in the growth of fruit trees, resulting in a variety of diseases such as yellow leaf disease, leaflet disease, black spot disease, rot and so on. According to the nutrient status, the correct fertilization method should be the mixed application of retting organic fertilizer, nitrogen, phosphorus and potassium compound fertilizer, trace elements and biological bacterial fertilizer to meet the needs of growth and development of fruit trees and obtain high yield.

3. Improper fertilization time

During the peak period of fertilizer and water demand of fruit trees from September to November, one is to expand the fruit, the second is to color, the third is to provide nutrients for flower bud differentiation, and to provide a variety of nutrients for tree storage nutrients. But many fruit growers do not apply fertilizer for fear of losing a small amount of fruit, pushing the prime time of fertilization to November or even February-March of the following year. According to the data, the nutrients stored by the trees from September to October accounted for 80% of the total 85% of the whole year, while from November to December, the root growth stopped and the water absorption rate was low because of low temperature. At this time, the nutrient storage of fruit trees accounted for only 65% and 70%, affecting the yield in the coming year.

4. Fertilization is too deep.

Many fruit growers do not pay attention to scientific and reasonable fertilization regardless of variety and tree age, and can apply it as deeply as possible. Crop growth, fertilizer, water, light and temperature are inseparable. Most of the roots are concentrated in the soil layer of 20-30 cm, which is the concentration area of nutrient absorption. Some fruit growers apply 80 cm deep, and some are even more than 1 meter big. as soon as they are watered, nutrients seep into the lower layer with the water, and the roots can not absorb them at all, resulting in a waste of fertilizer. Therefore, it is generally applied to 15-20 cm, and then watered, and the underwater infiltration is just combined with the root system, which can get twice the result with half the effort.
