Solidago canadensis is a foreign malignant weed that seriously threatens agricultural production and ecological environment. According to recent surveys, Canada's goldenrod has entered the flowering period, which is a crucial period for prevention and control. Timely control can effectively cut off the spread of seeds and reduce the number of bases in the coming year. All localities should, in accordance with the principle of territorial management, strengthen organizational coordination and technical guidance, promptly carry out the prevention and control actions of the yellow flowers in the fall, and strive to achieve the overall goal of non-proliferation in sporadic areas and non-proliferation in the film-forming areas. The relevant matters are hereby notified as follows:
1 Strengthen comprehensive inspections and implement prevention and control responsibilities
Recently, phytosanitary institutions at all levels should promptly organize a comprehensive inspection of technical personnel, focusing on investigating abandoned land or areas to be developed, along rivers and lakes, along highways and railways, and existing occurrences and surrounding areas, in time to grasp the occurrence of Canadian goldenrod in the area under their jurisdiction. In the case, clearly identify the area and area, identify and map the distribution. It is necessary to timely report the occurrence of distribution to relevant departments and units and implement the responsibility for prevention and control.
2 Strengthen comprehensive prevention and control, improve the control effect
All localities should rush to carry out scientific prevention and control according to local conditions for different types of occurrence areas before the ripening of the goldenrod seeds in Canada. For sporadic plants, manual extraction should be carried out and the underground rhizomes should be completely removed. For arable land that occurs in pieces, mechanical ploughing and re-cultivation should be carried out, and the residual stems and stems should be removed in time, and appropriate crops or greening should be planted. Plants, in order to improve the control effect and land utilization; for the occurrence of non-cultivated land along the river along the river, along the road along the railway and other non-cultivated land, canola can be sprayed with glyphosate or oxyfluorine glyphosate and other agents. All localities should vigorously organize prevention and control professional teams and implement unified prevention and control. Areas with conditions can carry out specialized prevention and control through the government's purchase of services, and improve the efficiency of prevention and control operations.
3 Strengthen organizational coordination and promote prevention and control as a whole
The control of canadensis in Canada is a quarantine measure carried out in accordance with the law and is highly concerned by the society. According to the principle of “grading responsibility and territorial managementâ€, agricultural departments at all levels should take the initiative to report the epidemic situation to the local government and organize administrative control; to report and publish publicity materials through the news media to improve the society's correct understanding of Canadian goldenrod And to prevent confidence; it is necessary to strengthen coordination with transportation, water conservancy, urban construction, railways, development zones, etc.; it is necessary to strengthen inspections and guidance, timely report the epidemic eradication progress, and urge the areas where the operations are not effective to prevent them within a time limit.

Zhejaing Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Meter, Mass Flowmeter, Mass Meter, Flow Meter, Flowmeter, ATEX, IECEx & CE approved. The product range covers different size from DN03 to DN150, and bigger sizes are being developed.
Sealand mass flow meter is designed and produced according to world`s latest Coriolis technology with exelent 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.
