What are the benefits of turning over the soil to increase soil permeability?

1. Improve soil structure.

There are many benefits of plowing the land in winter, a lot of land is planted with stubble, coupled with the unreasonable application of chemical fertilizer, there are a large number of substances that can not be decomposed in the soil, there are compaction, watering and fertilization can only be in the surface layer, and the utilization rate is not high. After the soil is ploughed, the soil below is turned up, the soil structure is improved, and the soil quality becomes looser, which is more conducive to the growth of crops.

2. Eliminate soil insect eggs.

In winter, when the temperature is relatively low, some germs and insect eggs will freeze to death after the soil is turned up. The weather is cold and frozen, and there is no suitable living environment for pests and diseases in the soil, so there will be a lot less when it comes to spring, which reduces the trouble of controlling pests and diseases to a certain extent. If the soil is not turned over, the deep soil temperature is relatively high, which provides a place for the eggs to overwinter, and when planted in the spring, there will be relatively more insect infestations.

3. Prune the root system.

Deep ploughing of the orchard can increase the active layer of soil, improve aeration conditions, increase soil moisture content, enhance soil microbial activity, facilitate the decomposition of soil organic matter, improve soil fertility, and at the same time in the process of deep ploughing, the root system can be properly pruned, promote the proliferation of fibrous roots, expand the total number of roots, and lay a good foundation for the healthy growth of the tree body in the coming year, lush branches and leaves, and large fruit quality.

4. Alleviate the pressure of spring sowing production.

Ploughing the soil in winter, after a winter of moisture cultivation, can restore the soil performance to the best state, can make the soil structure form a balanced state, as long as the spring flowers bloom, the temperature rises, the winter fallow land can be directly spring sowing production, can effectively alleviate the winter spring ploughing and spring sowing production pressure.

It can improve the soil structure, it can also eliminate insect eggs, prune the root system, can promote yield, can resist lodging, improve quality,. It can also increase the active soil layer and improve the air permeability of the soil.

It makes crops grow better. Grow a little faster. Grow stronger and the harvest will be a little better. Doesn't grow worms.

In this way, the root system of crops can be well developed, the lack of oxygen can be avoided, the crops can be healthier, lodging can be avoided, and soil compaction can be avoided.

In the process of crop growth, it is necessary to cultivate and loosen the soil, dig ditches and drain the water in order to ensure the growth of roots. For example, rice should be cultivated during the growth process, and a very important role of cultivating is to loosen the soil, and the soil after loosening the soil contains sufficient air and can store sufficient water, which can ensure the growth of crop roots. When the root system grows well, the crop will stand more firmly in the soil and absorb more water and salt.

The role of cultivating loose soil

Loosening soil is mainly to prevent soil compaction, which will affect the contact of the root system with air and cause root rot. Loosening soil loosens the soil, dredges the air, and raises the ground temperature. At the same time, it is also conducive to the activity of soil microorganisms, promotes the decomposition of organic matter, increases the ability of soil nutrients, and improves nutritional conditions.

Secondly, loosening soil can regulate soil moisture, protect moisture and prevent drought. After loosening the soil, it can break the soil compaction, cut off the capillary, prevent the evaporation of water below the soil layer, and achieve the effect of water storage and moisture conservation.

The plant absorbs water and mineral elements.

All need to be actively transported.

, that is, the transport of energy consumed, and the energy comes from the linear three-dimensional in the apical cells to provide energy, which is oxidized into water by oxygen and decomposition to release energy.

The roots of plants need oxygen in the air, and frequent loosening of the soil can loosen the soil, and the air in the soil crevices increases, which is conducive to the respiration of the roots and promotes the growth of the roots. If the soil is compacted, the air in the soil is reduced, which inhibits the respiration of the roots.

It also inhibits the growth of roots.

Deep ploughing in the garden in winter can effectively protect the flowers and trees and lay a good foundation for the growth of flowers and trees in the coming year.

The benefits of winter turning the garden soil are:

1. Deep ploughing in winter can improve the soil structure. In the growing season, due to the frequent operation activities of flowers, such as spraying, pruning, fertilization, cultivating and weeding, etc., the aggregate structure of the soil is destroyed, so that the soil forms a compacted layer, and the permeability is greatly reduced. Through deep ploughing, it can not only break the compacted layer and increase the soil voids, but also promote the further maturation of the soil and the differentiation of organic matter in the soil, and effectively improve the soil fertility.

2. Deep ploughing of garden soil in winter can also improve the cold resistance of flowers and trees. Deep ploughing increases the active soil layer, creates a good water, fertilizer, air and heat conditions for the root system, leads the roots to take deep roots, and enhances the tree potential. At the same time, deep ploughing can cut off a part of the fibrous roots, promote the germination of new roots of the plant, so that the root system can be renewed.

After deep turning, bury the farmer's manure, a layer of soil and a layer of fertilizer, which can protect the flowers and trees from wintering safely.

3. Deep turning can eliminate many pests of flowers and trees. Many pests of flowers and trees overwinter in the soil in winter, some are directly killed by machinery and tools when they are turned over, and some are frozen to death when they turn to the surface of the soil, or are eaten by natural enemies. In addition, there are some pests of flowers and trees that overwinter in fallen leaves, dead branches and weeds, and can be turned deep into the soil when turned deeply.

The method of deep turning is: around the main trunk from shallow to deep to the surrounding turning, the topsoil is turned to the bottom, the subsoil is turned to the top, and the large soil blocks that are turned up can not be broken for the time being.

Deep soil ploughing and cultivating loose soil in orchards can loosen the topsoil, increase soil aeration, increase ground temperature, promote microbial activity and nutrient effectiveness, remove weeds, promote root extension, and regulate soil moisture. The soil moisture content is 60% of the water holding capacity in the field, and 80% is suitable for the root growth of fruit trees.

Water (soil moisture) also affects root growth, and when the available water in the soil decreases, first the cell elongation decreases, and the density of root hairs increases in the short term, and then the growth stops and the wood corks until the resorptive roots die.

If the soil moisture is insufficient, the corking of new roots will be accelerated, the growth will be slowed down, and the growth will stop to a certain extent, and the root damage of soil drought will be heavier than that of the aboveground part, and the root growth will stop due to the lack of silver and water, which will correspondingly make the aboveground part show nutrient deficiency. Sudden drought in the atmosphere also has an inhibiting effect on root growth.

The main principle that deep ploughing of the soil can play a role in weeding is to reduce or eliminate the growth of weeds by destroying and disturbing the plant roots and seeds in the soil, blocking their growth and germination. Specifically, deep ploughing of the soil can produce the following effects:

Destruction of weed seeds: Weed seeds are usually on the top layer of the soil, and deep soil plowing can bury these seeds deep under the soil, making them unconditioned to grow, reducing or eliminating the growth of weeds.

Disturbing weed roots: Deep soil ploughing will detect the decay of plant roots in the disturbed soil, causing them to lose their growing conditions, thereby reducing or eliminating the growth of weeds.

Improve soil structure: Deep soil ploughing can improve soil structure, increase soil aeration and water permeability, improve soil fertility and water use efficiency, thereby promoting the growth of beneficial plants and inhibiting the growth of weeds.

Increase soil temperature: Deep soil ploughing can increase soil temperature so that weed seeds in the soil cannot germinate, reducing or eliminating the growth of weeds.

In conclusion, deep ploughing can play a role in weeding through a variety of ways, but it should be noted that excessive deep ploughing will destroy soil structure and reduce soil fertility and water use efficiency, so the appropriate depth and frequency should be selected according to the specific situation. At the same time, deep soil ploughing is not the only weeding method in Rolling Mountain, and it can also be combined with mulching, tillage, chemical weeding and other methods to achieve better weeding results.

The seeds of plants can be buried deep under the soil, causing the seeds to consume a lot of nutrients when germinating, and the seeds of herbaceous plants are small and will be depleted.
