The same applies to fertilization. Why do people have more and better fruits? In fact, in terms of fertilization, there are many misunderstandings. If you do not pay attention, it is easy to have improper fertilization, resulting in poor fertilizer efficiency, slow effect, and even cause the death of fruit trees.
Misunderstanding of fertilization time
1. After fruit-fertilizer-fertilizer is applied, it usually takes 3-7 days to be absorbed and used by fruit trees after fertilization. Therefore, if fertilization occurs after fruit trees are fertilized, it will result in longer crop-fertilizer time, resulting in reduced yield. Therefore, fertilization should be based on the characteristics of crops need fertilizer fertilizer in advance.
2, fruit trees to see flower fertilization Some people like to apply winter fertilizer, the winter, the tree's roots are almost dormant, the ability to absorb nutrients is very weak, fruit trees fertilization is the best time to pick the fruit before falling leaves. The most direct result of flower fertilization is the apparent size of the fruit tree.
Misunderstanding of fertilization method
1, the same formula, the same amount, the same effect is very simple, the main difference between fat and thin people is not to eat more and less problems, but the absorption of more and less problems. Fertilizers are the same, and the same amount of the same formula will have a distinct difference in nutrient utilization due to the product itself. This is why some products with low total nutrients will perform better than those with high nutrient content.
2. The nearer the fertilization, the better the fertilizers absorb the fertilization method. There is a greater harm because the nutrient component of the fruit tree is absorbed in the root hair area, and the nearer the fertilizer is, the farther from the plant stem, the farther the fertilizer is from the plant nutrient absorption site. The more difficult it is to absorb, if too much fertilizer is applied and the concentration is too large, it is also prone to “burning seedlingsâ€.
Misunderstanding
1, only basic fertilizer, not top-dressing many farmers after the application of basal fertilizer, no longer top-dressing, this method of fertilization is unscientific. The duration of basal fertilizer effect is limited, especially for sandy loam soils with poor fertility and water retention capacity.
2. Pay attention to chemical fertilizers and lighten the role of organic fertilizers. Currently, high-efficiency fertilizers can realize immediate production increase. However, the role of organic fertilizers in fruit production is irreplaceable, and attention must be paid to the application of organic fertilizers to fruit trees.
3, neglect the balance between elements when fertilizing fruit trees need to absorb a variety of nutrients, in addition to a large number of elements, the elements of trace elements, organic activation of nutrition is also very important. At the same time, the proportion of various elements in the soil also affects the absorption of fruit trees. There is a promotion or antagonism among various elements. For example, excessive application of nitrogen fertilizer will inhibit the absorption of potassium, boron, copper, zinc, and phosphorus. Too much phosphorus will inhibit the absorption of potassium and magnesium.
