In recent years, in the production of fruit trees, it is often seen that there are many flowers, less fruit, and poor economic benefits. The reason is analyzed. In addition to the large amount of leaves on the pruning, resulting in poor scenery conditions, the main reason is that the base fertilizer is not applied on time. As a result, the nutrient level of the fruit trees is low, resulting in a low fruit setting rate. Therefore, the application of fertilizer in autumn to improve the nutritional level of fruit trees is the basis for high yield and quality.
Organic fertilizers are used as base fertilizers, including ring fertilizer, cow dung, chicken manure, etc. These fertilizers contain relatively complete types of nutrients (such as nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, zinc, iron, manganese, boron, copper). In addition to a large amount of organic matter, it not only satisfies the needs of fruit trees for various nutrients, but also improves soil, enhances soil fertility, and improves fruit quality.
The base fertilizer is best for autumn, and it is generally about one month before the fruit trees fall, that is, around the National Day. At this time, it is the third peak period of root growth of fruit trees. The roots of fertilization are easy to heal and can promote a large number of new roots. In addition, the fertilizer is easy to decompose and is beneficial to the absorption of roots. Stop growing, the newly absorbed nutrients are mainly accumulated and stored, which can improve the nutrient level of the tree and enhance the cold resistance.
The stocking nutrition of fruit trees plays an important role in the annual cycle of fruit trees. It has a direct impact on the germination, flowering, fruit setting, leaf spreading and rooting of wintering and springing of trees. The size of the fruit depends on the number of cells and the size of the cell volume, and the number of cells depends on the nutritional level of the stock, which is determined by the nutritional status of the tree in that year. Therefore, if the tree is poorly stocked, the fruit will be flat. When the tree is malnourished, the fruit will grow longer and the fruit type index will be larger.
In the application of organic fertilizer, combined with partial quick-acting fertilizers (such as nitrogen, phosphorus, potassium, zinc, iron, magnesium, etc.) to improve tree resistance and improve flower bud quality.
The amount of fruit absorbed and fertilizer increased with the increase of fertilization amount within a certain range, and the amount of fertilizer increased and the amount of absorption decreased. Fruit trees and varieties vary, and the amount of fertilizer required is different. Generally, apples and grapes in the deciduous fruit trees need the most fertilizer, and young trees require less fertilizer. Trees with more large trees should be applied more appropriately, especially phosphorus. Potash. The fertility of the soil is different, and the amount of fertilization is different. Generally speaking, the result garden is 0.5 to 1 kilogram of fruit, which is 0.5 kilograms of fruit, to achieve the goal of high yield and high quality.
There are two main methods for producing the base fertilizer. One is the annular fertilization method: an annular groove with a width of 30-60 cm and a depth of 30-50 cm is dug under the outer edge of the canopy, and the fertilizer and the soil are mixed and sprinkled. Inside the ditch, then cover the soil. This method is suitable for saplings with a small root distribution. The second is the strip fertilization method. According to the size of the crown, 1-2 grooves are opened between the rows of fruit trees or between the plants. The width of the groove is 50-70 cm and the depth is 30-50 cm. The fertilizer and soil are mixed and sprinkled in the ditch. Covering soil; the ditch can be rotated and used every year. This method applies to the big tree in the result period. After fertilization, water should be poured once to make the soil fertilizer and the root system close.
