西红柿植株本身能够产生不定根系,但是不定根系过多不是一种正常情况。一般在植株根系发育不良,出现维管束病害、植株长势受到抑制时,植株为了自我调节,需要有更多的根系吸收营养,会产生大量的不定根系。所以说西红柿植株产生大量的不定根系,不是叶片的病害,而是属于一种系统性的危害。具体发病原因及防治措施如下:1.根系发育不良或者出现根腐等土传病害不定根系过多主要原因是:雨水进棚或者露天西红柿遭受雨水危 Tomato plants themselves can produce adventitious roots, but adventitious root system is not a normal situation. Generally in the plant root system dysplasia, the occurrence of vascular bundle disease, plant growth is inhibited, the plants in order to self-regulation, need more roots to absorb nutrients, will produce a large number of adventitious roots. So tomato plants produce a large number of adventitious roots, not leaf disease, but rather belongs to a systematic harm. The specific causes and prevention measures are as follows: 1. root system dysplasia or root rot and other soil-borne diseases adventitious roots too much main reason is: rain into the shed or open-air tomatoes suffering from the risk of rain
