Rice is the main food crop in China. The traditional flooding cultivation and planting mode not only consumes large amounts of water, but also causes serious waste of water resources, low water use efficiency, and is likely to cause environmental pollution. With China's population growth and rapid economic development, water shortage has become one of the most serious strategic problems facing our country, which seriously restricts the sustainable development of agriculture. The research results at home and abroad show that rice has a certain degree of water and drought amphibious, and has great water-saving potential. At present, the traditional flooding cultivation mode has gradually shifted to the water saving cultivation mode. Water-saving cultivation of rice can significantly increase the evapotranspiration and single leaf water use efficiency. Practice has proved that rice film-covered water-saving cultivation can promote rice growth and development, increase the number of effective tillers, increase production. So how can we measure the moisture in the soil and help control the soil moisture? At this time we can use related instruments such as a soil moisture tester. Soil moisture is the main source of rice water, and its content is directly related to the growth status of rice. The soil moisture meter is also capable of measuring soil moisture and its function is similar to a soil moisture meter.
Under normal circumstances, the higher the soil moisture content, the adequate transpiration of rice leaves, the more luxury transpiration, so the water consumption is high. With the decrease of soil water content, the cumulative water consumption in the whole growth period, the water consumption in each growth period and the water intensity decreased. Film flooding can inhibit the evaporation between the trees in the early stage of fertility, and can raise the temperature of the soil, promote the growth and development of rice, and lead to premature aging. In addition, it can greatly save water resources.
The soil moisture tester has GPS function. While testing the soil moisture content, it can measure the precise information of the measuring point (latitude and longitude), can display the position information of the sampling point at any time, and can store information such as position and moisture, group number, etc. Into the host, and through data records, to conduct spatial differences and comparisons, is a full-featured, high-performance products. The soil moisture tester achieves automatic sampling and processing of moisture content and three-dimensional position information. It processes the signals of sensors and GPS receivers and calculates corresponding data. It plays an important role in crop growth, water-saving irrigation and so on. At the same time, it provides scientific basis for differential water-saving irrigation, and accurate water supply will also help improve crop yield and quality. Another parameter of the soil - soil nutrients also has a great influence on the growth of the crop. The determination of this parameter also has corresponding instruments such as a soil nutrient tester, which will not be discussed here. We will explain in detail in other articles.

Semi-automatic Saw Blade Pipe Cutting Machine

1. Gearbox:

2. A self-lubricating bearing:

It is added at the movable joint between the head and the connecting seat, which can lubricate the connecting shaft in order to prevent the direct friction causing abrasion, so it helps to improve the working life, and accuracy that reduce the vibration of Saw Blade.

3. Regulating valve:

Regulating valve: the control valve imported from Taiwan is adopted, with high machining accuracy, stable flow control and even cutting speed. Fast return speed, improve work efficiency.
