去年一入冬,我就像往常一样,对放在院内的盆花进行了简单的防寒处理。但和以往不同的是,由于院内放着一些准备扔掉的麦草(即麦秸),觉得可以用来防冻,就顺手放在其中几盆里了。今年开春以后,这些花仍在原处摆放,一直未曾搬动。最近,有些情况令我十分在意。一是同样浇水,盖了麦草的一定时间内没有明显的干旱表现。二是同一树种,盖了麦草的长势要好些。如两株石榴,一株盖了,另一株未盖,长势就明显不同。就是同一盆银杏,今年也比去年长得旺盛。这一情况使我很兴奋,激起了我进一步观察和思考的兴趣。前一段时间,我连续多天反复观察,并几次把草扒开察看,终于有了初步的认识。想当初,给盆花盖麦草,仅仅是为了防冻,现在看来是一举多得了。1.保持盆土湿润。盖了麦草的盆花,浇水时水浸得快,水分蒸发慢,能使盆土较长 Last winter, I, as usual, carried out a simple cold-proof treatment of potted plants in the courtyard. But unlike in the past, because the yard was set aside to be thrown away some straw (ie, wheat straw), that can be used for antifreeze, and easily placed in which a few pots. After the spring of this year, these flowers are still in place and have never been moved. Recently, I was very concerned about some situations. First, the same watering, wheat straw covered a certain period of time there is no obvious drought performance. The second is the same species, covered with wheat grass growing better. If two pomegranates, one covered, the other did not cover, significantly different growth. Ginkgo is the same pot, this year than last year grew strong. This situation made me very excited and aroused my interest in further observation and reflection. Some time ago, I repeatedly observed for several days in a row, and a few times the grass patrol open inspection, and finally have a preliminary understanding. In the beginning, to give pots cover wheat straw, just to prevent frost, and now it seems to serve one another. 1. Keep basin soil moist. Covered straw flowers, watering when flooding fast, slow evaporation of water, can make basin soil longer
