Eggplant cracking is a common phenomenon in the eggplant growth process. This occurrence not only seriously affects the eggplant fruit quality, but also affects the eggplant's commercial value, resulting in economic losses. Therefore, effective measures should be taken to prevent and control the agricultural production. . The analysis of the reasons can know that the main reasons for cracking eggplant are temperature, trace elements, fertilization, pests, moisture, etc., so the use of soil moisture measuring instrument scientific management of water is also an important measure to effectively avoid eggplant cracking.
In the process of eggplant growth, unscientific water management is one of the causes of eggplant cracking, especially in the case of soil moisture re-evolution, it is very easy to cause skin cracking. This is because when the eggplant is fruited and during the fruiting period, the plant gradually takes nutrient uptake to reproductive growth. At this time, the plant needs more water, but if the eggplant fruit during the expansion, the fruit suddenly drops after rainfall. If the soil moisture is too large, or if it suddenly clears on a continuous cloudy or rainy day, it will cause the fruit to grow faster than the peel and form a large number of peels. Therefore, in order to avoid eggplant cracking, it is necessary to use a soil moisture meter to accurately measure the soil moisture and adjust it in time.
Using the soil moisture measuring instrument, not only can we know the real-time soil moisture status during the eggplant growth process, so that accurate irrigation can be done to make up for the turbulent time and provide sufficient water supply for its growth. At the same time, measures can be taken to keep the soil in a proper condition. The moisture range avoids skin cracking caused by soil moisture changes. Therefore, it can be said that the use of soil moisture measuring instrument scientific management of water is an effective measure to avoid eggplant cracking, but due to many factors that cause eggplant cracking, in addition to the application of a soil moisture meter to monitor soil changes in production management, It should also make use of other agricultural instruments to pay attention to temperature, trace elements, fertilization, and pests to provide security for eggplant growth.
Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. Butterfly valve that can be used for on-off control of low-pressure pipeline medium means that the closing member (disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing. of a valve.
Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.
