The latest key points of fertilization for peach trees in spring

Peach tree is one of the common economic fruit trees, the fruit can be eaten, peach blossoms can be seen, peach wood can be used as carvings, peach gum is still an excellent medicinal material, it can be said that the whole body is a treasure. At present, peach trees are more and more widely planted, and it is now in the spring ploughing period, so how to fertilize and manage peach trees? Let's get to know it with the editor.

1. Fertilization time

Peach trees are the earliest in spring growth activities in fruit trees, and the supply of nutrients is also earlier than other transfer of ownership. Generally, the temperature begins to rise deeply after the Beginning of Spring, and then the nutrient demand of peach trees begins to increase gradually, so it is necessary to seize the opportunity to apply pre-bud fertilizer. It is generally applied in the first half of the Beginning of Spring, with 0.5kg of nitrogen fertilizer, 0.3kg of potash fertilizer and 0.2kg of phosphate fertilizer per plant, preferably mixed with mature human and animal feces and urine fertilizer.

2. Fertilization formula

Formula should be adopted when applying fertilizer to ensure the all-star and balance of fertilizer. If the fertilizer element is too single, it will not only affect the normal growth and development of peach trees, but also lead to poor fruit flavor, small size, yellow leaves, leaflets, fruit shrinkage disease and other deficiency. Therefore, it is suggested that the fertilizer should be based on rotten farm manure and an appropriate amount of compound fertilizer to ensure the comprehensiveness of fertilizer.

3. Fertilization method

When applying fertilizer to peach trees, the amount of base fertilizer accounts for about the total amount of fertilizer application. Generally, 50% of phosphorus and potassium fertilizer and 40% of nitrogen fertilizer are added to the base fertilizer, and the rest of nitrogen, phosphorus and potassium fertilizer is applied step by step according to the nutrient demand of peach trees in each growth period. Generally, peach trees were applied 2-3 times in sprouting stage, hard kernel stage and fruit expansion stage. For the orchards with deciduous leaves in the early stage of the previous year, extra-root fertilization should be strengthened to promote the restoration of tree potential. Low concentration urea solution can be sprayed 2-3 times before germination, and twice from germination to mid-July, with an interval of about one week.

4. Points for attention

Peach is a shallow root tree species, most of the roots are distributed in the 20-30 cm soil layer, so peach fertilization should be appropriate shallow, fertilization depth of not more than 30 cm is appropriate. In addition, the horizontal roots of peach trees are generally concentrated in the outer part of the crown, and the growth direction of the root system is often extended because of the fertilization position, so fertilizer should be applied deeper and farther away from the root system, which can promote the root system to develop in depth. expand growth surface and fertilizer absorption surface.
