To ask what kind of soil quality is the best, which is most conducive to crop growth, then many agricultural experts may tell us that it is a soil with multiple soil-grain structure. Plant growth is good or bad, the yield is high or low, and the quality of agricultural products is closely related to soil structure. It can also be said that the most ideal structure of soil is the pellet structure. It is precisely because of this that in the current soil improvement, the soil aggregate structure becomes one of the most important criteria for measuring soil quality, and the construction of the soil aggregate structure requires a specialized soil aggregate analyzer for the determination and analysis.
Modern agricultural research shows that granule structure is a very good structure of the soil. If the soil granule structure is large, its ability to coordinate water, fertilizer, gas, heat, and fertilizer will be stronger, and the soil fertility will also be strong. The higher, the better the crop will grow. However, in the past, due to improper fertilization and application of fertilizers, it caused serious damage to agricultural soils. Therefore, in fact, many clusters of arable soils in China currently do not meet the standard, but due to different regions, their severity will be different. At this time, with the help of the soil aggregate structure, it is possible to develop customized scientific improvement plans for different plots, so that the problematic soil can form a pellet structure quickly. This is because the soil is getting healthier and the fertility is becoming stronger.
In fact, many soils begin to have bad conditions or worsen. They all have a common feature. The structure of the group is constantly decreasing. In the context of modern advocates of healthy soil cultivation, soil aggregate analyzers are used to fight soil aggregates. The analysis can determine the extent of soil deterioration to a certain extent, help agricultural workers better and faster find out where the soil problems are, let the soil have more granule structure, make the soil have water vapor, nutrient supply and accumulation coordination, and plough The characteristics of good nature and well-grown roots are often afflicted by a fertile soil environment, which provides an important guarantee for high yields and stable production in agriculture.
An electric vehicle (BEV) refers to a vehicle that is powered by an on-board power supply and uses motors to drive wheels to comply with road traffic and safety regulations. As the impact on the environment is relatively small compared to traditional Cars, its prospects are widely optimistic, but the current technology is not yet mature.
Working principle: battery-current-power regulator-motor-power transmission system-driving car (Road).
Pure electric vehicle
A car driven by an electric motor.
Compared with fuel-powered vehicles, the main difference (different) between pure electric vehicles is the four major components, driving motor, speed controller, power battery, and car charger. Relative to the gas station, it consists of a public ultra-fast charging station. The quality difference of pure electric vehicles depends on these four major components, and its value also depends on the quality of these four major components. The use of pure electric vehicles is also directly related to the selection and configuration of the four major components.
Hybrid
Refers to a car that can derive power from at least the following two types of on-board stored energy:
Consumable fuel or rechargeable energy/energy storage device.
According to the power system structure, it can be divided into the following three categories:
Series Hybrid Electric Vehicle (SHEV): The driving force of the vehicle only comes from the electric motor hybrid (electric) vehicle. The structural feature is that the engine drives the generator to generate electricity, and the electric energy is sent to the motor through the motor controller, and the motor drives the car to drive. In addition, the power battery can also provide electric energy to the motor alone to drive the car.
Parallel Hybrid Electric Vehicle (PHEV): A hybrid (electric) vehicle in which the driving force of the vehicle is supplied simultaneously or separately by the electric motor and the engine. The structural feature is that the parallel drive system can use the engine or the motor as the power source alone, or can use the motor and the engine as the power source to drive the car.
Hybrid Hybrid Electric Vehicle (CHEV): A hybrid (electric) vehicle with both series and parallel drive modes. The structural feature is that it can work in series mixed mode or in parallel mixed mode, taking into account the characteristics of series and parallel.
