The latest misunderstanding of fertilization for fruit trees in spring

Spring is the period when fruit trees begin to sprout. At this time, everyone must know the importance of fertilization. Spring fertilization should be balanced, reasonable and scientific. At the same time, we should also pay attention to the application of trace elements and increase the input of biological agents. In addition, we should also pay attention to a few points. Let's understand it with the editor.

1. Partial application of chemical fertilizer

Many fruit growers often apply a large amount of chemical fertilizer, while ignoring the application of medium and trace elements and organic fertilizer, resulting in too much nitrogen fertilizer, which not only causes the waste of fertilizer, but also causes the deposition of phosphorus elements, which is directly manifested by the serious consolidation of orchard soil, the imbalance of fruit tree growth and development, and out of control of disease and pest control. Moreover, it will also cause low yield, poor quality and poor flavor, all of which are caused by the partial application of chemical fertilizer, so fertilization in spring must be scientific and reasonable.

2. Applying base fertilizer in spring

Many fruit growers have the habit of applying base fertilizer in spring, but there is no such habit in autumn. The temperature in spring is on the high side, the soil moisture is poor, and the base fertilizer is not fermented for a long time, so it is difficult for the tree to absorb it. To a certain extent, resulting in a waste of fertilizer. With the application of base fertilizer in autumn, the soil moisture is better, but also conducive to fertilizer decomposition and root absorption, can timely supplement nutrition to the tree, but also conducive to blossom and fruit the following year.

3. Fertilization is too early

Topdressing for fruit trees should be applied during the fruit expansion period, if fertilization is too early, it is easy to cause nutrient loss, and potash fertilizer is applied during the fruit expansion period, which makes the fruit surface glossy, bright color and crisp meat, but there is no such effect if it is applied at the flowering stage, so topdressing should be timely, not too early or too late.

4. Rely too much on foliar fertilizer

At present, most of the foliar fertilizers on the market are plant growth regulators, and the effect is very fast after spraying, so many farmers apply base fertilizer instead of topdressing, individual fruit growers do not apply base fertilizer, and rely too much on foliar fertilizer. This practice is extremely inappropriate. More than 95% of the nutrients needed for plant growth and development come from the soil, while the leaf absorption rate is less than 5%. Foliar fertilizer is only suitable for fruit trees when they are short of fertilizer, which can well supplement the current needs of the plants. but it can't meet the needs of the whole growth period.
