If Rugao is an important production area in China, the red dates produced in this area are called Rugao red dates and Loulan red dates. These red dates are big and beautiful, and the oval shape is only when the flesh is crispy and sweet, and the dried meat is soft and sweet. After eating, Yuxiang mouth full of mouth, the quality is very good, but in the growth process of Ruoqiang red dates, it will inevitably suffer from pest problems, so in order to protect the production of jujube, improve the quality of ruoqiang red dates, the area used a solar insecticidal lamp In order to control pests, a green prevention and control technology system was established for red dates in Ruoqiang.
In the past, if insecticide was used in the Ruoqiang area, pesticides were used to kill insects. This not only polluted the environment, but also caused pesticide residues in Ruoqiang jujube, which affected the quality of the product and made the insects resistant to insecticides. In the long run, pests have become more and more harmful. Difficult to be killed, production and life have been affected, and solar insecticidal lamp uses a physical principle of insecticide, is a harmless to humans and animals, the pest has no damage to the agricultural environment. The light wave it emits has a strong insect attracting effect, and the insecticidal effect is very significant. It can greatly reduce the base number and density of jujube pests, thus reducing the use of pesticides to a certain extent, and thus reducing the pesticide residues in jujube. Helps improve the quality of Ruoqiang red dates. Moreover, the solar insecticidal lamp has low use cost, is convenient for moving and can be placed in any place where it is needed, so it is very convenient to use and is very suitable for promotion and use in jujube cultivation in Ruoqiang area.
Under the current background of vigorously focusing on green agricultural production, the use of solar-powered insecticidal lamps to carry out the prevention and control of red dates and insect pests in Ruoqiang meets the production requirements of modern pollution-free, green, organic red dates, not only helping to promote the region. The quality of jujube dates, as well as the creation of geographical brands such as Ruoqiang Jujube, can also play an important role in the further determination of red jujube's core competitiveness in the market.
Valve Part is kind of pipeline fittings, which is used to open and close, control, adjust and control the flow of medium parameters (temperature, pressure and flow). According to its function, it can be divided into the cut-off valve, check valve, regulating valve, etc.
Valve is the control unit in fluid conveying system, having function of cut-off, regulation, guide, to prevent the reverse flow, voltage regulator, the leakage of the shunt or overflow and so on. Valve parts used in fluid flow control system, have quite a wide varieties and specifications, from the most simple cut-off valve to all kinds of valves used in extremely complex automatic control system.
The valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium. According to the material, valve part is divided into iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome molybdenum steel valves, molybdenum chrome vanadium steel valve, dual phase steel valves, plastic valves, non-standard custom-made valves, etc.
