in the past, when making plant specimens, fresh plant branches and leaves were usually added to absorbent paper with clamps and tied with ropes. A new absorbent paper was replaced every day and dried under pressure for 1~2 weeks. This method is time-consuming and laborious. It requires a large amount of absorbent paper. Especially in the cold winter and a large number of collected plants, the problem of insufficient absorbent paper will affect the production progress.
For plant disease specimens, in order to avoid deterioration, they should not be placed in direct sunlight for a long time, because direct sunlight will promote the decomposition and fading of internal pigments, so they must be covered in time.
once any mildew trace or insect damage is found, it should be handled in time. We can put it in a dry and ventilated place, but do not spread it out in the hot sun to avoid the branches and leaves from rolling up and breaking. When a little mildew trace is found in the plant disease sample, it can be brushed with a brush.
