Description
Technical field
The present invention relates to a kind of planthopper field and catch harvester and using method thereof.
Background technology
Planthopper, belong to Insecta Homoptera (Homoptera) Delphacidae (Delphacidae), being the important pests in Oryza sativa L. grain-production, the planthopper of Oryza sativa L. of causing harm is mainly brown paddy plant hopper (Nilaparvatalugens), white backed planthopper (Sogatellafurcifera) and small brown rice planthopper (Laodelphaxstriatellus).Especially when brown paddy plant hopper and white backed planthopper great outburst, often result in Oryza sativa L. and step on circle, cause the Oryza glutinosa underproduction, planthopper also can propagate Rice Virus, and in a word, planthopper is extremely serious at China's occurring and damage, often result in heavy economic losses, be one of significant threat of producing of China Oryza sativa L. grain security.In recent years, along with the factors such as global climate and environment changes, China's tradition rice cropping and cropping system also there occurs huge transformation, the continuous popularization and application of high yield and high quality new rice variety, the composite factors such as the chemicals such as agriculture chemical come into operation in a large number, the occurring and damage of planthopper and infestation regularity are also constantly changing, planthopper occurring and damage is in constantly increasing the weight of trend, the outburst frequency of planthopper, occurring and damage area, the indexs such as field population number all constantly record high, research of agricultural science and the great attention of grain-production department need to be caused, reinforcement monitoring and early warning need to be continued through, take effective prevention in time and control technical measures, guarantee the safety of China's Oryza sativa L. grain-production.
How planthopper continuous and effective being controlled is the important tasks of science of all plant protection scientific workers, this needs constantly strengthen scientific research and observe and predict early warning work, and these research-on-researches all be unable to do without desk research and field field investigation, such as, carrying out prediction, field efficiency test is evaluated, in the research process such as indoor biological determination of activity, a large amount of planthoppers need to be gathered from field investigation and seizure, owing to the feature of planthopper is small, breeding is fast, adult has wing to fly, nymph is good at jumping, the difficulty that field observation and seizure gather planthopper is big, in addition, it is all at autumn in summer high temperature season occurring and damage due to planthopper, field gathers and the working strength of investigation planthopper is also very big.The national standard of planthopper field Censes Methods is to adopt ocular estimate, the feature of kind jumping and the difference of artificial range estimation can be flown due to planthopper, often there is huge error in the test data investigated, cannot accurately reflecting field practical situation, the science of survey data and accuracy also cannot be effectively ensured；The traditional seizure acquisition method of planthopper utilizes porcelain dish, clap net, the instruments such as pest sucking device, these methods have common shortcoming, it is exactly that working procedure is loaded down with trivial details, inefficiency, and workload and labor intensity are big, currently also there are some Patent designs with handle strainer as planthopper sampling instrument, planthopper is allowed to fall within the rice field water surface by rice clump of flapping, then pick up planthopper with strainer and shift in loading container, the method there is also obvious deficiency, cannot realize normally picking up planthopper when water depth in rice field is inadequate, and, the dense collection of rice in rice field, the spacing distance of rice clump is little, operation easier is big, in addition, in rice field, the water surface often has a large amount of Herba Spirodelae and weeds etc., this technical operation difficulty is made to strengthen further.
