The pests and diseases that damage wheat before winter are mainly underground pests, wheat yellow dwarf disease, and clump dwarf disease. At the same time, during this period, it is also the infection period of wheat-etching and sheath blight, and comprehensive measures should be taken for prevention and control. For the control of underground pests, 40% methyl isoflavone 1500 times liquid can be used to water the ridge; to control the total erosion and sheath blight, 20% of the powder rusting emulsifiable concentrate 100g or 15% powder rusting 150g per acre, 75kg of water , Shunmai ridge sprinkler irrigation; wheat yellow, plexus dwarf disease occurs in heavier plots, can spray 40% of 1,500 times liquid milk 1500 times on wheat and weeds within 5 meters wide inside and outside the wheat field, in order to eliminate Media such as mites and Laodel. Wheat fields with more weeds can be removed with chemical herbicides. In addition, it is strictly prohibited to graze indigo. Livestock and poultry indigo can greatly reduce the area of ​​green leaf of wheat, seriously affecting the manufacture and accumulation of photosynthetic products, affecting tillering, and reducing production.

Alcohol Mass Flow Meter
Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Alcohol Mass Flow Meter, Alcohol Mass Flowmeter, Alcohol Coriolis Meter, Mass Flow Meter Alcohol, Coriolis Mass Meter Alcohol, ATEX, IECEx & CE approved.
Sealand meter is designed and produced according to world`s latest Coriolis technology with better appearance, stability and accuracy to measure mass flow rate of a fluid traveling through a tube, widely applied to alternative energy, oil & gas, chemical, food & beverage, industrial energy, marine, power, pulp & paper, water & wastewater industries, etc.
Mass flow meter measures the mass based on Coriolis effort. The operating principle involves inducing a vibration of the tube through which the fluid passes. The vibration, though not completely circular, provides the rotating reference frame that gives rise to the Coriolis effect. While specific methods vary according to the design of the flow meter, sensors monitor and analyze changes in frequency, phase shift & amplitude of the vibrating flow tubes. The changes observed represent the mass flow rate and density of the fluid.
