What are the aspects of soil tillage? What are the functions?

Improve the physical condition of the soil tillage layer, adjust the ratio of solid, liquid and gas phases, and improve the structure of the tillage layer. For compact soil tillage, tillage can increase soil voids, improve permeability, facilitate precipitation and irrigation water infiltration, reduce surface runoff, retain moisture and store water, and promote the decomposition of microorganisms and release available nutrients. For the loose soil layer, tillage can reduce soil voids and increase the anaerobic decomposition of microorganisms.

The first is semi-ploughing, which is used after the harvest of crops in late autumn and early spring. The second method is rotary tillage, which uses a rotary tiller to spin the soil.

Rational soil tillage has three functions. First, the tillage layer is loosened and deepened, thereby improving the physical and chemical properties of the soil. The second is to turn the upper and lower layers of soil, promote the better maturation of the lower soil, and also restore the aggregate structure of the upper soil.

At the same time, it has the effect of burying weed seeds, crop residues, mixing fertilizers, and eliminating pests and diseases. The third is to level the soil surface, which can not only reduce soil water evaporation, but also create good conditions for irrigation, sowing, and seedling unearthing. In short, through deep tillage, the soil structure can be improved, the water and fertilizer retention capacity can be improved, and weeds can be reduced, which creates good conditions for seed germination, cuttings rooting, and seedling root growth.

Soil is the basis for the growth of crops, despite agricultural production techniques.

Therefore, in agriculture, we have to rely on traditional soil planting methods, make good use of soil network resources, reform and innovate soil farming systems, improve soil standards, increase organic fertilizers, improve soil colloidal and physical and chemical properties, cultivate soil fertility, and create a suitable environment for crop growth and store rich nutrients.

It has the effect of immobilizing crop plants: the roots of crops are deeply rooted downward, except for the absorption of nutrients and carbonates.

In addition to nutrients, it also has a fixed effect on itself, the heavier the root system is rooted, the more stable the plant stands, the higher the level of lodging resistance, so as not to be blown down by the wind in the growth, or due to more precipitation, the root soil is soft and the wind falls down the seedlings, which endangers the construction and growth of the crop itself.

Soil: Soil is an ancient legend of iron ore.

Formed by regolith, soil organic matter is produced by the rotting of leaves and roots of vine plants. The soil stores a variety of nutrients (organic compounds, light fertilizers, calcium, magnesium, silicon, sulfur, boron, zinc, manganese, molybdenum, iron, sodium and other trace elements) that are essential for the growth of green plants.

The soil has the function of fixing the root system of green plants, which can provide nutrients for green plants, and soil organic compounds can provide nutrients for microbial strains to make them live and reproduce and <>

Metabolites (organic matter, green plant growth conditioner (auxin) in the reproduction process of soil microbial strains (auxin.

Indoles), etc.), organic matter can melt some water-insoluble mineral elements and metal compounds in the soil for plant absorption, which can promote the production of stable soil colloids. The level of soil organic matter represents the level of soil fertility. It is because of the necessity of agriculture and animal husbandry, in other words, the importance of food, that everyone will talk about agricultural issues, and everyone can attach great importance to agricultural issues.

The opening of the state is a concrete and major manifestation of the state's attention to agricultural issues!

Soil is the basis of crop growth, despite the further development of agricultural production technology and the success of soilless cultivation technology experiments, but for large-scale crop planting, we still can't get rid of our dependence on nature, we have to rely on traditional soil planting methods, make good use of soil network resources, reform and innovate soil farming systems, improve soil standards, add more organic fertilizer, and improve soil colloidal and physical and chemical properties.

Agricultural planting is inseparable from the soil situation, which directly affects the yield, but also affects the economic benefits, affects the follow-up attention, and also affects the growth of plants.

The quality of the soil can affect yields, but also diseases, weeds, and fertilizers.

1. Improve soil structure. The soil in the root layer of crops is moderately loosened and a good aggregate structure is formed in order to absorb and retain the right amount of water and air, and promote seed germination and root growth.

2. Eliminate weeds and pests. Cover weeds in the soil or expose stumbling pests to the surface and die.

3. Mix crop residues, fertilizers, pesticides, etc. in the soil to increase their effectiveness.

4. Flatten the surface or make it into a certain shape such as ditching, furrowing, ridge, ridge, etc., so as to facilitate planting, irrigation, drainage or reduce soil erosion.

5. Compact the soil that is too loose to a moderate density to maintain soil moisture and facilitate root development.

6. Improve the soil. Translocate soils with different textures from each other. For example, the upper layer with heavy salinity content is moved to the lower layer, or the first or second layer of the upper, middle and lower layers is translocated to improve the soil quality.

7. Remove stones, shrub roots or other debris in the field.

The main purpose of soil tillage: to create a good tillage structure and a moderate pore ratio; regulates the presence of soil moisture; reconcile the contradictions between the factors of soil fertility; removal of weeds and loose topsoil; Formation of high-yield soils.

Objective: To create a good tillage structure and a moderate pore ratio; regulates the presence of soil moisture; reconcile the contradictions between the factors of soil fertility; removal of weeds and loose topsoil; Formation of high-yield soils.

The natural vegetation is called natural soil, and the soil that has been cultivated and managed by humans is called cultivated soil.

Black soils are different from natural soils and cultivated soils.

Soil tillage is a series of measures taken to improve soil fertility by applying mechanical methods according to the requirements of crop growth for soil. Among them, it mainly includes: ploughing, harrowing, suppression, ridge formation, tillage and other links.

Through soil tillage, it can regulate the soil water, fertilizer, gas and heat conditions, reduce weeds, diseases and insects, and create good conditions for the growth and development of crops.
