First, increase the application of organic fertilizer
By applying human, animal manure, urine fertilizer and compost, manure, green manure and other organic fertilizers with high organic matter content to increase and maintain the soil organic fertilizer content, where conditions permit, a large amount of fertilization (river mud, grass carbon, etc.) The organic matter content has a significant effect.
Second, the straw returned to the field
Straw returning is an effective measure to improve soil and increase soil productivity. First, the straw is applied to the soil after being piled up; the other is that after the crop is harvested, the straw is chopped and scattered on the surface, and then plowed and pressed directly to the field, which can improve the physical properties of the soil and promote the formation of soil aggregate structure. Increase the ability of ventilation, water permeability and fertilizer retention to improve soil fertility.
Third, a reasonable rotation
Reasonable rotation is the farming method of land-raising. Pay attention to two points in the rotation: First, increase the planting area of ​​legumes appropriately. In the process of rotation, planting a legume crop for four years can increase the nitrogen content in the soil, while beans After the green manure crops are turned into soil, a large number of roots, stems and leaves can increase soil organic matter, improve soil physical and chemical properties, and improve soil fertility. Second, planting soil-consuming crops must control the number of years, such as beet to have seven annual rings, sunflowers must Once in a four-year round, beans and melon crops are not heavy, not smashed, and they must be rotated for more than five years. This will help restore soil fertility and prevent disease.
Fourth, planting grass fertilizer field
It is strongly recommended to grow legume forage to increase fertility and increase economic output. At present, the forages that can be planted include grass rhinoceros, alfalfa, etc., in order to improve soil, fertilize soil fertility, and improve soil productivity.
V. Reasonable adjustment of the proportion of agriculture, forestry and animal husbandry
The restoration of forestry development is a favorable measure to balance the ecology, improve the climatic conditions, and turn the vicious circle into a virtuous circle. Reasonable animal husbandry development can provide a large amount of organic matter to the soil, which is a direct measure to increase fertility and increase crop yield.
High Frequency Ranging Sensor Module
A high frequency ranging sensor module is a device that uses high-frequency signals to measure the distance between the sensor and an object. It typically consists of a transmitter and a receiver, which emit and receive high-frequency signals, respectively.
The module works by sending out a high-frequency signal, such as ultrasonic or radar waves, and measuring the time it takes for the signal to bounce back after hitting an object. By calculating the time of flight, the module can determine the distance between the sensor and the object.
High-frequency ranging sensor modules are commonly used in various applications, such as robotics, industrial automation, and automotive systems. They provide accurate distance measurements and can be used for obstacle detection, object tracking, or proximity sensing.
High-frequency laser distance sensors have a high measurement frequency and can provide real-time distance data, suitable for scenarios requiring quick responses, such as dynamic obstacle avoidance, autonomous driving, and robot navigation. These sensors ensure that the system can promptly perceive environmental changes and react quickly, ensuring safe and reliable operation.
