What are the reasons for soil compaction? Are there any good improvements?
In the cultivation of crops, we often see a lot of land that has been compacted. The soil of these lands is not wet at all, and the dry soil is tied together to form a hard and dry clod. Everyone in this land knows that there is no nutrients, and it is difficult to plant crops on it. So why is the soil tied? What are the reasons for the soil compaction? It may be more complicated than we think. Let's take a look at it to get the right medicine. First, the cause of soil compaction 1. The reason for the soil texture itself: If the soil texture is heavy, it is easy to appear soil compaction. Moreover, the soil itself is relatively ventilated and tempered. 2. Unreasonable fertilization: The soil organic matter content determines the physical and chemical properties of the soil. When the organic matter content is low, the soil physical and chemical properties will deteriorate, affecting the activity of microorganisms, thus affecting the formation of soil aggregate structure, leading to soil compaction problems. There is also a long-term single application of chemical fertilizers, which can also cause soil compaction. 3. Waste contaminated soil: The film and plastic bags are not cleaned up in time, so that they will remain in the soil, and the formation of harmful substances will seriously pollute the soil and cause soil compaction. 4. The destruction of the plough layer structure: Unreasonable repression and ploughing of the upper layer of the soil will lead to the destruction of the soil superstructure and damage the soil aggregate structure. Second, soil compaction improvement measures 1. Improve soil texture: If the soil texture itself is a soil that is easy to compact, then the soil itself must be improved first. 2, rational fertilization to improve soil compaction: increase soil organic matter content, do not long-term single fertilization when fertilizing crops. 3. Clean up the waste in time: In order to prevent the plastic film and other wastes from solidifying in the soil, it is necessary to clean it in time, which is also to prevent soil pollution. 4, protect the soil layer: Because the land layer is easily damaged by machinery or man-made, so try to protect it as usual. Soil compaction has many disadvantages, which not only makes the crops lack of nutrients, but also makes planting difficult, which affects the production of crops. Therefore, in the soil itself, everyone should pay attention to the problem of soil compaction.
Health Monitor (Health Care Monitor) is based on the principle of pulse pressure method, and based on the established theory, the model is divided into compartments, and a series of calculation formulas are deduced by linear correlation algorithm. After these formulas are corrected by nonlinear compensation and clinical experience parameters, a set of reflecting cardiac function, vascular condition, blood state and microcirculation function can be obtained.
The main function:
1. It can quantitatively detect more than 30 important parameters such as human heart function, blood vessel elasticity, blood viscosity, microcirculation, etc., and display the actual measured value and normal value range of each parameter, and give out a prompt for exceeding the standard. 2. Real-time display of pulse waveform, accurate observation of premature heart beat, arrhythmia and other phenomena. Give timely prompts to patients who may suffer from diseases such as hyperlipidemia, hyperviscosity, arteriosclerosis, coronary heart disease, and microcirculation disorders.
use:
It is carefully designed for the urgent needs of the market for Household Breathing Machine, cardiovascular health care and sub-health status detection. It has the function of non-invasive and rapid detection of human heart, blood vessels, blood, microcirculation and pulmonary function parameters, especially suitable for hospitals and community medical care. Health care, health census and selection of medicines and health products, etc.
