也许不会有人把养花与卫生纸联系起来,但笔者在多年的养花初中中将二者巧妙结合,用以播种诸如矮牵牛、四季海棠一类的微小种子,很成功。具体来说,就是先将白色卫生纸铺在栽种基质上,然后再播种,以提高种子散落排列的均匀度,取得理想的发芽率。有关的几个重要环节如下:
Perhaps no one will associate flowers and toilet paper, but the author in the years of flower middle school will be the combination of the two cleverly used to sow seeds such as Petunia, Begonia small seeds, very successful. Specifically, the first is the white toilet paper spread on the planting substrate, and then sowing, in order to improve the uniformity of scattered seeds arranged to achieve the desired germination rate. The relevant several important links are as follows:
