How to fertilize peach trees in spring? These key points you need to master
Peach trees are one of the common economic fruit trees. The fruit is edible, the peach blossoms are ornamental, the peach wood can be used for carvings, and peach gum is an excellent medicinal material, so it can be said that the whole tree is a treasure. At present, peach tree cultivation is becoming more and more widespread, and right now it is the spring farming season, so how should peach trees be fertilized and managed? Follow the editor to learn about it.
1. Fertilization time
Peach trees are the earliest among fruit trees to begin spring growth activity, and the tree's nutrient supply also needs to be earlier than that of other fruit trees. Generally, after the Beginning of Spring, the temperature begins to rise, and at this time the nutritional demand of peach trees begins to gradually increase, so it is necessary to seize the opportunity to apply pre-bud fertilizer well. It is generally applied half a month before the Beginning of Spring, with 0.5 kg of nitrogen fertilizer, 0.3 kg of potassium fertilizer, and 0.2 kg of phosphorus fertilizer per tree, preferably mixed with decomposed human and livestock manure and urine fertilizer.
2. Fertilization formula
When fertilizing, formula fertilization should be adopted to ensure the comprehensiveness and balance of the fertilizer. If the fertilizer elements are too single, it will not only affect the normal growth and development of peach trees, but also lead to poor fruit flavor, small size, and deficiency symptoms such as yellow leaves, small leaves, and fruit shrinkage disease. Therefore, it is recommended to mainly use decomposed farmyard manure when fertilizing, paired with an appropriate amount of compound fertilizer, to ensure the comprehensiveness of the fertilizer.
3. Fertilization method
When fertilizing peach trees, the amount of base fertilizer accounts for about half of the total fertilization amount. Generally, 50% phosphorus and potassium fertilizer and 40% nitrogen fertilizer are mixed into the base fertilizer, and the remaining nitrogen, phosphorus, and potassium fertilizers are applied in split applications according to the nutrient needs of peach trees at each growth stage. Generally, it is applied 2-3 times during the bud break stage, pit hardening stage, and fruit expansion stage of peach trees. For orchards that experienced early leaf drop the previous year, foliar fertilization should be strengthened to promote recovery of tree vigor. A low-concentration urea solution can be sprayed 2-3 times before bud break, and urea solution can be sprayed 2 times from after bud break to mid-July, with an interval of about one week between applications.
4. Precautions
Peach trees are shallow-rooted tree species, with most of the root system distributed in the 20-30 cm soil layer, so peach tree fertilization should be appropriately shallow, and the fertilization depth should preferably not exceed 30 cm. In addition, the horizontal roots of peach trees are generally concentrated slightly farther out at the outer edge of the canopy, and the growth direction of the root system often extends because of the fertilization location, so fertilization should apply the fertilizer farther and deeper from the root system, which can promote the root system to develop deeper, expanding the growth area and the fertilizer-absorbing area.
