Method for preserving primary colors of red and yellow plant disease specimens

Abstract

The invention provides a method for preserving the primary colors of red and yellow plant disease specimens. The method comprises the following steps: (1) collecting, finishing and sterilizing the plant disease specimens; (2) carrying out color fixation; (3) carrying out color repairing; (4) preserving the primary colors. The method creatively comprises the three color processing steps, i.e., color fixation, color repairing and primary color preservation, and the specimens of two colors can be preserved by using one method. The raw materials used in the method are safe and environment-friendly; the method is simple and easy to implement as well as time-saving and labor-saving, can be used for making while collecting, can realize batch production, and is used for preserving the original shapes and primary colors of the specimens; the preserving fluid is clear and transparent; therefore, the method has positive practical significance for application in the field of plant pathology teaching and scientific research.

Description

technical field [0001] The invention belongs to the field of phytopathology, and in particular relates to a method for preserving the primary colors of red and yellow plant disease specimens. Background technique [0002] Red and yellow plant disease specimens are one of the important components of plant disease specimens. There are many differences in the preservation of red and yellow plant disease specimens and green specimens. Green specimens are solid colors, accounting for a large proportion. The research efforts are relatively large, and the current technology is relatively mature. Red and yellow disease specimens are basically fruit-type specimens. A complete red and yellow plant disease specimen is often a fruit with green leaves, fruit stalks, fruit pedicles, fruit branches, etc. To preserve the original color of a complete specimen, it must be Save multiple colors at the same time. At present, there are not many researches on the preservation technology of red a...

AI Technical Summary

Problems solved by technology

At present, there are not many researches on the preservation technology of red and yellow plant disease specimens. Generally, one kind of preservation solution is used for direct preservation, and the color preservation effect is not good. The color difference between the specimen and the fresh specimen is too large, and the fruit is easy to crack.

Some methods with better color retention effect contain formaldehyde in the formula. As we all know, formaldehyde is a poisonous and harmful substance, which is not conducive to the health of users.
