Due to the frequent rains recently, especially in some areas, heavy rain has caused great damage to vegetables. After the rain, the stems and leaves of the vegetables are adhered to the ground and the pores on the leaves are blocked, which seriously affects the breathing, transpiration, and photosynthesis of the vegetables. The vegetables attacked by the rainstorm will be blown, the stems and leaves will be broken, the soil will appear compacted, the air in the soil will be reduced, the anaerobic respiration of the roots of the vegetables will be reduced, the resistance will be greatly weakened, even cause death, and it will also cause various diseases. Occurrence and spread, causing unexpected losses.
Control methods: 1. After the rain, the vegetables were drained in a timely manner, and water was poured with well water to reduce the soil temperature, increase the oxygen in the soil, and maintain the normal breathing state of the vegetables.
2. As far as possible the right-blowing plants will be righted to reduce the rot caused by mutual extrusion, so that the normal growth of vegetables.
3. After the storm hit, the root activity of vegetables was weak, and the water absorption was poor. Spraying foliar fertilizer in time, such as “Naihe Xeroxengâ€, enhanced the capacity of absorbing fertilizer and restored plant life.
4. Spraying hymexazol or spermacromlonitrile or ethyl allicin to prevent various diseases.
Ultrasonic water meter is a new type of water flow meter, by detecting the ultrasonic beam propagation in the water and tide by speed changes generated, which analyze and process water flow rate. Ultrasonic water meter is the use of ultrasonic time difference principle, the use of industrial grade.
Ultrasonic Water Meters have the following features: low initial flow rate, wider measuring range, higher measuring accuracy, good stability and no need to set parameters installed at any angle. No moving parts inside the unimpeded flow element, is not affected by impurities in the water, and long service life.
The ultrasonic water meters have excellent low flow detection capabilities, which can solve the problem of many traditional water meters, more suitable for water gradient charge, more for conservation and rational use of water resources and have broad market prospects and use,is a good product to as home water meter.
