Problems solved by technology

However, the current sampling method is difficult to pick out because the head shell is small and its color is similar to the surrounding plant debris, and it is easy to miss, and it takes a lot of time to carry out this process, which affects the progress of research.

Embodiment 1

[0034] Preparation method of dyeing agent 1 for isolating chironomid head shell subfossils

[0035] Add solid aniline blue, phenol, lactic acid and glycerin into water, and mix uniformly to obtain dyeing agent 1 (i.e., aniline blue dyeing agent), wherein, every liter of dyeing agent 1 contains 1.6g aniline blue, 22g phenol, 25g lactic acid and 85g glycerin.

Embodiment 2

[0037] The preparation method of this embodiment is basically the same as that of Example 1, except that:

[0038] Contain 1.6g methylene blue, 22g phenol, 25g lactic acid and 85g glycerol in every liter dyeing agent 2 (being methylene blue dyeing agent).

Embodiment 3

[0040] The preparation method of this embodiment is basically the same as that of Example 1, except that:

[0041] Contain 1.5g aniline blue, 20g phenol, 24g lactic acid and 88g glycerol in every liter of dyeing agent 3.

Abstract

The invention discloses a dyeing agent for a separated chironomidae head capsule subfossil, and a dyeing method of the dyeing agent. The raw materials of the dyeing agent include solid aniline blue, phenol, lactic acid and glycerol, wherein each liter of the dyeing agent contains 1.0-2.0g of the solid aniline blue / methyl blue, 20-30g of the phenol, 20-30g of the lactic acid and 80-90g of the glycerol. The dyeing method of the chironomidae head capsule subfossil dyeing solution provided by the invention is simple, and a preparation method is simple, so that an experimenter can perform sample selection more quickly, and the sample omission amount can be reduced as far as possible.

Description

technical field [0001] The invention relates to a dyeing agent, in particular to a dyeing agent for separating chironomid head shell subfossils and a dyeing method thereof. Background technique [0002] Chironomus larvae are one of the most abundant benthic animals in almost all freshwater environments, and are an extremely important part of the lake microfood web. As one of the most important functional groups in the soft bottom of the water body, it responds extremely quickly to changes in the water body environment. Therefore, chironomids are considered to be "biological projectors" for the evolution and assessment of the lake environment. [0003] As a direct reflection of the composition of chironomus populations at that time, chironomid headshell subfossils in sediments have been widely used in qualitative and quantitative restoration studies of lake environments in the past, including quantitative reconstruction of temperature, nutrition, water dissolved oxygen, and w...
