Recently, many vegetable farmers have reported that there are a large number of adventitious roots on tomato stems, and no similar situation has been seen before. The growth of the plants is very weak. Some of them have already appeared flowering. What is going on here? The analysis of various situations is as follows.
First, the reason analysis
Tomato plants themselves can produce adventitious roots, but excessive adventitious roots such as the vegetable growers are not a normal condition. Generally, when the plant roots are stunted and vascular bundle diseases occur and the plant growth is inhibited, the plants need more roots to absorb the nutrients for self-regulation and produce a large number of adventitious root systems. Therefore, tomato plants produce a large number of adventitious roots, not the diseases of the leaves, but rather belong to a systemic hazard.
Second, the specific reasons and prevention
1. Roots are stunted or soil-borne diseases such as root rot occur.
The main reason for the indefinite root system is: the rain enters the shed or the open-air tomatoes suffer from rain. After rainwater enters the shed, it can cause root damage or harmful substances that cause damage to the root system. In particular, the main root can be pulled out for detailed inspection.
Infected soil-borne diseases, such as root rot and verticillium wilt, can cause root rot and plants also have a large number of adventitious root systems.
Control methods: timely discharge of rain, pay attention to conservation roots later, you can flush chitin, alginic acid and other rooting and rooting fertilizers; for soil-borne diseases can choose the formula: water chestnuts + copper + copper + chitin rooting.
2. Infection of bacterial diseases
Bacterial pith necrosis and bacterial wilt, in particular, result in the destruction of the vascular system of the plant, which produces a large number of adventitious root systems on the stem.
Control methods: The key lies in prevention. You can choose bacterial agents such as bacteriocin, chloramphenicol, chlorobromoisocyanuric acid and other agents. At the same time, you can irrigate roots, mesobiocin + copper rosin + chitin.
3, burning root
The main reason is that the base fertilizer is unscientific. It has not been decomposed or unreasonably applied pesticides. This leads to burning of roots, and it also causes a large number of adventitious root systems in stems.
Control methods: Chong Shi EM biological bacterial fertilizer or chitin, solution to promote growth.
4, excessive use of inhibitors
Some vegetable farmers control the growth of plants, and they always need some foliar spraying agents, such as paclobutrazol, B9, and Adenosine, etc. If they are used too much, the growth of the plants will be inhibited too much, which will also lead to a large number of adventitious root systems.
Control methods: To promote the growth, you can choose chitin + cytokinin foliar spray, the effect is significant.
