Pest-insect survey sampler for plant root system

Abstract

A pest-insect survey sampler for a plant root system relates to the field of plant protection and ecological investigation and comprises a sampling barrel and a handle, wherein the sampling barrel isa cut tubular structure; the lowest part of the tubular body and a transitional part from a cut to the barrel wall is of a cutting edge structure which transforms from thin to thick; at least a semi-circular plug is designed at the upper bottom face of the sampling barrel; the outer arc of the plug is matched with the inner wall of the sampling barrel; a mounting bar is vertically fixed on the barrel wall; the transverse handle is fixedly mounted above the sampling barrel through the mounting bar; and the handle and the mounting bar are in a T shape. As the cut exists, simple sampling operation and complete sampling of pests and insects at plant roots can be realized; owing to plant root sampling without pest and insect escaping, and use of a desliming piece, a technicist can accurately and quickly determine the nature of pests and insects at the plant roots, and accordingly, can make a quick response to formulate correct prevention and control measures and schemes. Therefore, the plant pest-insect study efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the fields of plant protection and ecological investigation, in particular to an investigation sampler capable of investigating and sampling plant root pests, ensuring the integrity of the sampling root system and root pests, and preventing the pests from escaping. Background technique [0002] The root system is the main organ for plants to absorb nutrients and water. The absorption of nutrients by the roots of plants is the core of plant nutrition. If there is a problem with the root system of a plant, the yield will be reduced in the slightest, and the harvest will be wiped out in the severest case. Timely monitoring, detection of epidemics, and targeted prevention and control measures are important technical means to improve crop yield. Therefore, it is an important technical means to determine whether the plant root system is healthy or not to carry out sampling investigation on the development, disease and insect damage ...
