根据初中生物教学的内容，实验室必备一定的动植物标本。编号４１６０的花序类标本和编号４１６１的花冠类标本既要求保型保色，又要求浸制后长年不坏。对这类标本的制作从１９９１年开始，我们就进行了大量的研究实验，并取得了成功。现在制好的这类标本有大丽花、月季、石竹 According to the content of junior high school biology teaching, the laboratory must have certain animal and plant specimens. The inflorescence specimen No. 4160 and the corolla specimen No. 4161 require both shape retention and color retention, and require not to be damaged after infusion for many years. The production of such specimens began in 1991. We have conducted a large number of research experiments and achieved success. The specimens prepared so far include dahlia, rose, and dianthus
