大家都知道,救死扶伤,当个好医生是不容易的。那么当个植物医生是不是也不容易呢?确实是这样。当个植物医生,首先要知道庄稼是怎么长大的?需要什么营养和环境?也得知道植物不正常或不健康的样子。比如,叶片变黄,起了斑点,果实变形、腐烂或是植株枯萎等,这些都说明植物得了病。 Everyone knows that it is not easy to be a good doctor while he is going to save lives. So is it not easy to be a plant doctor? That’s it. When a plant doctor, we must first know how crops grow up, what nutrition and environment are needed, and we must also know whether plants are abnormal or unhealthy. For example, leaves turn yellow, speckled, deformed, decayed, or withered plants, all of which indicate that plants have become ill.
