记得小时候曾听老农说过,稻田里的稗子和稻禾总是同时生长,而且长得几乎一模一样。不过,只要人们仔细观察,它们之间还是有差别的:稻子总是沉甸甸地垂着头,而稗子却偏偏头颅高昂。种田人视稗如仇,对稗害无不深恶痛绝,因为它挤占了地盘,吸收了大量养分。 I remember when I heard the peasants talked about it as a child, the barnyard grass and paddy rice in the rice fields always grew at the same time and looked almost identical. However, as long as people look closely, there is a difference between them: the rice always hangs heavy head, but the tares are rather high head. Farmers see Echinochloa as an anger and do no harm to Echinochloa crus-galli because it occupies the site and absorbs a large amount of nutrients.
