Farmland soil water is most closely related to the growth of crops. It directly affects the water, gas, heat, and nutrients of crop growth. Surface water and groundwater can only be directly absorbed and utilized by crops because they have only a certain conversion relationship for soil moisture. Therefore, the status of farmland soil moisture is the core of the growth environment. Different crops need different moisture at different stages of growth. In general, the water requirement for crops at the seedling stage is relatively small. As the crop growth gradually increases, the maximum amount of water is stored during the vigorous growth period, and the water storage capacity at the mature stage gradually decreases. In addition, the critical period of crop moisture is also different. The critical period of crop moisture refers to the period when the lack of water in the soil has the greatest impact on the growth and yield of crops. Wheat: heading - irrigation period; corn: tasselling period; cotton: flowering and bolling period; leguminous crops: flowering period; rice: booting, heading period. Timely understanding of the state of soil moisture in different periods, combined with the weather conditions, and proposing targeted and scientific irrigation proposals for agricultural production are very necessary for agricultural production. How to measure soil moisture? Soil moisture meter is used to measure soil moisture special instruments, instrument only timely measurement of soil moisture, soil water can be timely recording, and the relevant data is stored in the host, ease of scientific research.
From the above, we can see that soil moisture conditions as an important indicator of agricultural production, need the relevant departments and personnel to give adequate attention. Soil moisture meter to measure soil moisture as fast professional equipment, capable of real-time measurements of soil moisture and soil moisture save a lot of information, and weather-related agricultural sector as this raw data, preparation of reports and charts soil moisture, combined with the weather the next few days Situation of scientific and rational water-saving irrigation.
The soil moisture meter provides a scientific basis for soil moisture and plays a guiding role for water-saving irrigation.
All-electric Injection Molding Machine
The all-electric injection molding machine is a machining injection molding machine which is powered by electricity. Thermoplastics can be injected into molding and processed into various molds. It is a kind of machine commonly used in the process of chemical material synthesis and processing.Its basic functions are as follows:
(1) Heat the plastic until it reaches a melting state;
(2) Apply high pressure to the molten plastic, so that it is injected and filled with the mold cavity.
