After the greenhouse, the roots of the vegetables are often called “white†by the farmers. This is also a good thing. The vegetable growers here never deep-sweep the soil and do not apply basal fertilizer, and they do not disinfect the soil. When the greenhouse vegetable is watered, it is poured into the roots of the posterior wall. This is even more a "forgotten corner." In this way, the vegetables growing here are very likely to become infected and become a source of infectious diseases in greenhouses. Therefore, to remind the vegetable farmers that soil disinfection should be done well before the greenhouse roots.
First of all, before the colonization of vegetables, 1000 times of carbendazim or 800 times of foramin can be used to uniformly spray the soil.
Secondly, before the vegetable is planted, DT1 gram of acetophora plus 1 gram is added to prevent root disease from invading. If it is to consolidate the control effect, after the planting and easing of seedlings, it can be used to add 1,000 times of CK and DT500 times to irrigate the roots, and 0.25-0.3 pounds of liquid per plant can effectively prevent the occurrence of root diseases.
In addition, it is necessary to pay attention to the addition of biological bacterial fertilizer, which is beneficial to the principle of biological bacterial fertilizer antibacterial bacteria to prevent the occurrence of soil-borne diseases, but it should be noted that biological bacterial fertilizer can not be used together with the fungicide to affect the application effect.
