西瓜是夏季各地普遍食用的重要果品,瓜皮多被废弃,瓜皮营养也很丰富,再加上瓜皮刚柔皆宜,故笔者在其可否直接做为母种培养基上进行了试验,具体制做方法如下: 一、瓜皮初处理。选择新鲜无霉烂的瓜皮,刮净内表皮上残留瓜瓤,洗净瓜皮表面泥土,晾晒一日,目的是使瓜皮失去部分水分。不晾也可以,但会因含水量大在灭菌时试管中积水,这部分水在接种时要倒去。二、切条分装试管。将处理好的瓜皮根据试管直径大小切成长条,粗细以能自由进入试管且能有接种针(钩)出入空隙为度,长度为试管长的1/2～2/3(此为整条装入试管),也可以将长条切成长2厘米左右的小块,4～6块首尾相接装入试管。
Watermelon is an important fruit commonly eaten all over the summer, more than the abandoned guapi, melon skin nutrition is also very rich, coupled with melon skin is safe, so I can directly as a mother’s medium on the test, Specific system made as follows: First, melon skin treatment. Choose fresh and rotten melon skin, scraping net residual epidermis melon, wash the surface of melon skin, drying day, the purpose is to make the melon lose some water. Do not air can also be, but because of the large water content in sterilized test tube in the water, this part of the water to be poured back when. Second, cut into pieces test tube. Will deal with good melon according to the size of the test tube cut into strips, the thickness to be able to freely enter the test tube and can have vaccination needle (hook) into the gap for the degree of length of the test tube length of 1/2 ~ 2/3 (this is the whole Into the test tube), can also be cut into long strips about 2 cm small pieces, 4 to 6 end to end into the test tube.
