Embodiment

[0032] Preparation method of standard sample of Euphorbia dentata:

[0033] Step 1 Source of standard samples: The seeds of Euphorbia dentatus are intercepted from entering the country. The seeds are multiplied after expert identification and planting verification. After harvesting, the seeds of Euphorbia dentatus were compared, and those that were relatively consistent in shape were mixed together to make a standard sample of Euphorbia dentatus.

[0034] The second step is to multiply the standard sample: choose different sowing periods according to the local climate conditions. Firstly, disinfect the soil, which can kill other weed seeds and pathogenic bacteria in the soil, then put the disinfected soil in large flower pots, and then put the flower pots neatly in the isolation net room, and make a good logo. In order to ensure the germination rate, Euphorbia dentata is accelerated before sowing. The growth conditions of Euphorbia dentatus were observed and recorded throu...

Abstract

The invention relates to a Euphorbia dentata Michx standard sample and belongs to the technical research field of plant quarantine standard samples. In the Euphorbia dentata Michx standard sample, a Euphorbia dentata Michx seed with a typical morphological characteristic is embedded in resin, so that the crystal Euphorbia dentata Michx standard sample is prepared. The preparation method of the Euphorbia dentata Michx standard sample comprises: preparing the representative Euphorbia dentata Michx standard sample by taking the Euphorbia dentata Michx seed captured in a laboratory as a raw material through procedures, namely isolation-planting, micropropagation, screening, preparation, uniformity inspection, stability inspection, identification, package, storage and the like. A verification basis is provided for weed quarantine verification work in a plant quarantine laboratory; and the detection level of the laboratory is improved.

Description

technical field [0001] The invention relates to a standard sample of Euphorbia dentata, and also relates to a preparation method thereof, which belongs to the technical research and development field of plant quarantine standard samples. Background technique [0002] Cleft-toothed Euphorbia ( Euphorbia dentata Michx), also known as Euphorbia sawtooth, belongs to the genus Euphorbiaceae. It is usually mixed in raw plant grains and seeds in the form of capsules and seeds, and spreads along with the transportation of raw plant grains and seeds. Euphorbia dentata can be harmful to various crops such as soybean, corn, wheat, etc. It has strong colonization ability, fast propagation, and toxicity. In view of this, the Ministry of Agriculture of my country has included Euphorbia dentata as an important quarantine object and included it in the "List of Imported Plant Quarantine Pests of the People's Republic of China". The entry-exit inspection and quarantine department, in the p...
