In terms of pest control, to further reduce the impact of pests and diseases on plant growth, scientific prevention and control measures are indispensable, and to achieve the goal of scientific prevention and control, the work that needs to be done in the early stages is to use a pest survey statistic instrument. The investigation of pests and diseases was carried out to understand the regularity of the occurrence of plant diseases and insect pests. Only when the plant protection personnel formulate prevention and control measures could the data be followed, and the farmers carried out prevention and control work based on these measures, they were able to achieve good control and prevention effects. Harm to a minimum.
At present, it is in the seedling stage of rapeseed growth. Although apparently the growth of rapeseed is good on this occasion, there may actually be some diseases and insect pests. If there is a large area of ​​pests and diseases, it will cause serious damage to rapeseed production. Therefore, it is very necessary to carry out investigation and prevention and control of rape seedling pests at this time. Plant protection personnel use pest survey statistics to carry out work, not only can improve the efficiency of pest and disease investigation, and better complete pest and disease investigation work, but also can effectively ensure the timely release of disease and insect intelligence guidance to help farmers conduct scientific prevention.
The technicians used pest survey statistics to find out that some pests such as tapeworms, cabbage caterpillars, and downy mildew were present in some plots. Among them, the average infestation rate of locusts was 30%, and the number of larvae was 320; the average rate of cabbage worms was average. 4%, 100 strains of 9 insects; the average incidence of downy mildew was 0.8%. According to the statistics of pest and disease survey statistics, the plant protection technicians developed scientific pest control measures for rapeseed growers and achieved targeted prevention and control. The control effect was very significant and not only effectively controlled rapeseeds. The number of pests in the ground and the serious occurrence of diseases are avoided, and the waste of pesticides is effectively reduced, the production cost is reduced, and the rapeseed harvest is guaranteed in the coming year.
L(R) series pumps are cantilevered horizontal, centrifugal slurry pumps ,which are also called Light Duty Slurry Pumps. They are designed for continuous pumping of lower abrasive and lower density slurries. The liner and impeller of this type pump can be replaced with wear-resistant metal or rubber material. They are widely used in metallurgical, coal, mining, building material.
