Dry land soil animal numeral field and construction method thereof

Abstract

The invention discloses a dry land soil animal numeral field and a construction method thereof. The dry land soil animal numeral field comprises at least one dry land capable of being used for a long time, an automatic monitoring device and an electric power supply device, and the distance between every two dry lands is more than 200 m; a square sample plot is arranged in the center of each dry field, and a certain distance is reserved between the sample plot and the edge of the dry field so as to avoid the edge effect; permanent landmarks are respectively arranged at four corners of the sample plot according to the geographic position, or fences are arranged at the boundary of the dry farmland where the sample plot is located; the interior of each sample plot is divided into a plurality of square grids by basic units, and the automatic monitoring equipment and the power supply equipment are arranged around the sample plot, underground, earth surface or overhead. According to the invention, the field dry land soil animal numeral sample plot is digitalized; namely, the digitalized, automatic and intelligent sample plot with full space coverage, all-weather time and three-dimensional samples is realized in three dimensions of space, time and soil animal diversity.

Description

technical field [0001] The invention belongs to the technical field of soil animal research, and in particular relates to a dry field soil animal digital plot and a construction method thereof. Background technique [0002] In dryland soil animal research, the construction and monitoring of long-term fixed monitoring plots are very important platforms and means. At present, small or large long-term fixed monitoring plots are often used, with different sizes, and soil fauna samples are collected by traditional survey methods, such as soil column method, hand picking method, trap method, observation method, fluke method, Electric shock method, etc., and carry out multiple dynamic investigations and monitoring regularly or irregularly. The current soil fauna survey is carried out by selecting some sampling points in the sample plot. Even if more sampling points are set up, it is impossible to monitor all spatial ranges, all spatial scales, and all soil animal samples of the en...

Problems solved by technology

There are several reasons why there is a time interval. (1) Due to the large workload in the field, if dynamic sampling is performed multiple times, it will bring a large workload in the field, and then bring heavy indoor identification and other related tasks. Due to the workload, many laboratories and scientific research teams cannot complete such a heavy task, so the next best thing is to adopt a strategy of sampling at a certain interval to reduce the amount of work; (2) The traditional sampling methods used are mostly destructive (that is, non- Environmentally friendly) sampling method, multiple and frequent sampling will cause great damage to the sample plot, change the soil environmental conditions in the sample plot, thereby changing the ecology, activities and other behaviors of soil animals, the dynamic investigation under this background Surveillance may capture human-interfered, inauthentic, ex-situ data

(3) Traditional sampling methods will basically cause the death of individual soil animals, and it is necessary to bring the killed and finalized specimens back indoors for identification and analysis, which is not conducive to the protection and maintenance of biodiversity. For those rare or endangered soil animals species, is a greater threat

[0004] There are also precious data that cannot be monitored by existing methods

For example, in the existing survey methods, soil animal samples are collected a few days after spraying pesticides, and only soil animal data after spraying pesticides can be obtained for a period of time, and it is impossible to monitor real-time and real soil animal data after spraying pesticides technically.
