When it comes to apple production, many fruit farmers understand that to cultivate a strong tree vigor, it is necessary to fertilize the roots of the tree. As the saying goes: Trees rely on roots, and fertile soil can grow roots. The growth environment of the root system in the soil is the basis for cultivating a strong tree vigor. The root system can only grow and develop in a fertile soil. Below I will talk about my personal understanding based on actual production for the reference of fruit farmers.
The sooner the base fertilizer is applied after fruit picking, the better
After half a month, part of the roots are cut off during the ditching and fertilization process, and the cut roots will give out new roots. The performance on the tree is that the leaf function is enhanced, and the reserves of nutrients are increased, which is good for the buds and long branches of the fruit tree in the second year. , Long leaves, flowering and fruiting provide convenient conditions.
Many fruit farmers did not realize the importance of fertilization in autumn. In fact, applying basal fertilizer in early autumn, it can be said that from the perspective of the fertilizer requirements of the fruit tree throughout the growth cycle, autumn fertilization actually saves money for fruit farmers, and the utilization rate of fertilizer can be said to reach 80% to 90%. The base fertilizer utilization rate applied in spring is only 30%-40%.
Applying base fertilizer in autumn will govern the growth of fruit trees throughout the year
Applying basal fertilizer in autumn is actually a very important part of the annual management and comprehensive management of fruit trees, and it is also an important part of truly underground management. The general fertilization standard is that organic fertilizer accounts for 70% of the total fertilization, with appropriate amounts of nitrogen, phosphorus, and potassium, plus appropriate amounts of medium and trace element fertilizers, and the total fertilization accounts for 70% of the annual fertilization. Increase the amount of organic and biological bacterial fertilizers and reduce the amount of chemical fertilizers, so that fertilization can change the problem of soil compaction.
Method of applying basal fertilizer for fruit trees in autumn
Fertilization follows the technical requirements of "early, complete, full, appropriate, even and integrated". 1. Apply as soon as possible and apply sufficient base fertilizer; 2. The type of fertilizer used for fertilization should be all; 3. The amount of fertilizer should be determined according to the target yield of the fruit tree; 4. The depth of ditching should be 20-40 cm during fertilization, and the crown Vertically below the periphery; 5. Sprinkle fertilizer in the ditch and mix evenly with soil to prevent excessive concentration of chemical fertilizers and root burning; 6. Before applying fertilizer, it depends on the soil moisture, that is to say, the soil moisture determines the fertilization.
