What are the methods to improve soil quality? How to operate specifically?

Due to the long growth cycle of fruit trees and the problems of fertilization by some fruit farmers, orchard soil is prone to problems. Fruit trees will absorb necessary nutrients for a long time, which will lead to the imbalance of soil nutrients. When the root system absorbs nutrients, it will secrete toxic and harmful substances and pollute the soil. This will cause problems such as soil hardening and chlorination, and affect the normal growth and fruit quality of fruit trees. So, how to improve the soil?

The situation varies from place to place. For example, the soil in southern orchards may be acidified, while the soil in northern orchards may have more saline-alkali flowers. The problem degree of orchard soil in the same place may be different. Therefore, if we want to improve the orchard soil, we should adopt different methods according to the specific conditions of our orchard soil. It is considered that the methods of improving soil mainly include the following aspects.

Fertilization is to strengthen soil management through fertilization. It is necessary to overcome the traditional method of only compiling chemical fertilizers, especially nitrogen fertilizers. Attach importance to increasing the application of a large number of mature farmyard manure or commercial organic manure, comprehensively and rationally apply fertilizers, increase soil organic matter and improve soil fertility. At the same time, pay attention to the soil moisture in the orchard and irrigate it thoroughly in case of drought to prevent water accumulation in the orchard and affect soil permeability.

Dig deeper. Turn over the orchard soil regularly every year to increase the active layer of soil, make the soil mature, increase the soil gap and improve the soil permeability. Especially the orchard with grass is accompanied by the foundation every year. It goes deep into the soil, turns over and destroys the grass roots in the soil, and transforms corruption into organic matter, which not only helps to eliminate underground pests, but also improves the activity of beneficial bacteria.

Return the straw to the field. When applying winter invitation source and base fertilizer at the end of autumn every year, it is necessary to go deep into the soil and add a certain amount of crop straw and deciduous weeds. Introduction for several years can effectively improve soil organic matter and change soil quality.

The orchard grows grass. Planting grass in the orchard has been accepted by many fruit farmers now, and planting grass can determine the microclimate of the orchard. At the same time, when the weeds in the orchard grow to a certain height, the wooden tray is deleted and rotted and buried in the soil, becoming organic matter. You can also use the method of planting green manure to turn the grass directly on the soil to improve the fertility of the soil.

If the orchard soil is seriously oxidized or chlorinated, chemicals can be used to adjust the pH value of the soil or change the orchard soil. In other words, dig the problematic soil in the orchard, load the high-quality soil and turn it into orchard soil.

Conclusion There are many ways to improve the soil in orchard, but the key is to improve the soil with appropriate methods according to the specific conditions of the soil in your orchard, so as to lay the foundation for the growth of fruit trees in the future.
