Abstract
The cotton leaf fresh-keeping device comprises a box body and a box cover, wherein the box body is a polypropylene plastic box body, the box cover is a polypropylene plastic box cover, a layer of polyurethane artificial sponge is filled at the bottom of the box body, and seams are uniformly formed in the polyurethane artificial sponge. The utility model discloses an anti cotton bollworm nature bioassay cotton leaf device that keeps fresh, fresh-keeping time can reach more than 30 days, and fresh-keeping cotton leaf does not discolour, not wither soft, does not become the quality and rot, and fresh-keeping has the cotton leaf and produces the vitality of new root, and does not need to change cotton leaf and culture medium midway during indoor anti cotton bollworm nature bioassay, also need not the switching test cotton bollworm larva, and the bioassay is easy and simple to handle, test cost, accuracy height.
Description
Technical field
The utility model relates to the cotton leaf preservation device of a kind of bollworm resisting biologicall test.
Background technology
The bollworm resisting indoor bioassay originates in the research and development of soil of transgenic Bt cotton, the 2-3 sheet true leaf that indoor bollworm resisting biologicall test will be measured material-changed over to the Insect Resistant Cotton apical growth of anti insect genes such as the Bt exactly cotton bollworm low instar larvae of feeding, observe to measure the pest-resistant effect of material, among the biggest problem of running into be exactly the fresh-keeping problem of cotton leaf.Some units put into test tube or culture dish or the triangular flask mensuration of feeding with the cotton leaf of bollworm resisting biologicall test, owing to reasons such as the easy dehydration mummification of the cotton leaf of mensuration, problems such as the cotton leaf fresh keeping time of ubiquity weak point, difficult control of temperature, and when manually changing feed, easily cause artificial damage, influence measurement result.The more agar medium fresh-keeping method of present domestic usefulness, because of media surface is swum, regular meeting is drowned the cotton bollworm larvae of surveying.
Summary of the invention
The purpose of this utility model just provides a kind of easy and simple to handle, testing cost, the cotton leaf preservation device of bollworm resisting biologicall test that accuracy is high.
The cotton leaf preservation device of bollworm resisting biologicall test of the present utility model, comprise box body, lid, box body is the polypropylene plastics box body, and lid is the polypropylene plastics lid, the box body bottom is filled with one deck polyurethane artificial sponge, evenly has sealing on the polyurethane artificial sponge.
The cotton leaf preservation device of bollworm resisting biologicall test of the present utility model, during use, inject appropriate amount of purified water, with tweezers cotton seedling true leaf is uprightly inserted in the sealing of polyurethane artificial sponge again in the polyurethane artificial sponge, each sealing is inserted a leaf, afterwards at box body loam cake upper box cover.
The cotton leaf preservation device of bollworm resisting biologicall test of the present utility model, fresh keeping time can reach more than 30 days, fresh-keeping cotton leaf nondiscolouring, do not wither soft, never degenerate rotten, fresh-keeping have a vitality that cotton leaf bears new root, and do not need to change cotton leaf and medium during the indoor bollworm resisting biologicall test midway, do not need the switching test cotton bollworm larvae yet, give birth to survey easy and simple to handle, testing cost, accuracy height.
The figure explanation
Fig. 1 is the utility model structural representation.
Embodiment
