Greenhouse vegetables are now a major mode of vegetable cultivation in China. At present, greenhouse planting is mainly used in all parts of our country, greenhouse planting can effectively improve the yield and quality of vegetables is welcomed by many people. However, when growing vegetables in the greenhouse, vegetables are often prone to the phenomenon of dead trees. So how to prevent and cure the dead vegetables in the greenhouse? The following editor will give you a brief introduction, let's have a look!

1. Soil disinfection

When growing vegetables in the greenhouse, we must often observe the growth of vegetables. When the phenomenon of dead plants in vegetables is found, the dead plants must be taken out of the shed in time. Then use quicklime to do a comprehensive disinfection of the soil around the mouth of the dead tree to prevent the spread of germs, leading to the spread of the disease. Can also use ethyl aluminum, chlorpromazine and other agents for spraying disinfection. Each spraying must ensure that the soil is soaked in order to ensure the effect. However, it is mainly to give priority to prevention, strengthen prevention in order to avoid some unnecessary losses.

2. Chemical root irrigation

As I just said, the main thing to prevent the death of vegetables is to take precautions. Therefore, when we grow vegetables, we can use metalaxyl, mancozeb and other chemicals to irrigate the roots of vegetables that do not have dead plants to enhance the disease resistance of vegetables. There are many medicaments that can be used, such as Chunleimycin, Wang Copper and so on. However, it should be noted that the dosage must be controlled, not too much, to prevent drug damage and counterproductive. We can also add an appropriate amount of rooting agent to the agent, which can not only improve the resistance of the root system, but also achieve the purpose of protecting the root system.

3. Control watering

After the phenomenon of dead plants in vegetables, we must stop watering, disinfect the planting hole in time and do a good job of chemical root irrigation, and then use carbendazim and other agents to fully disinfect the shed. Reduce the base number of pathogens in the shed to prevent germs from spreading with water. However, although germs can be eliminated when disinfecting and irrigating roots, microbes in the soil will also die as a result. Therefore, after the treatment, we should apply biological agents to the soil in time to increase the number of beneficial bacteria in the soil and avoid the proliferation of bacteria. And it is also very beneficial to the growth of the root system, which can enhance the resistance of the root system. However, the use time of disinfection and biological agents should be kept at about 10 days to ensure its effect.

4. Improve the soil

In fact, dead vegetables are a common problem in planting. However, in hardened, salinized soil, the situation is even more serious. And if the temperature is low and too much watering, then the lack of oxygen in the roots, resulting in capillary root rot, causing a variety of diseases, there will naturally be the phenomenon of dead trees. Therefore, it is necessary to prevent and cure the dead trees in time, but the most important thing is to solve the soil. Therefore, soil improvement and conservation is very important, to provide a good soil environment for vegetables is the key measure to prevent and control dead vegetables.

The above is a brief introduction to the prevention and control of dead vegetables in the greenhouse. That's all for today's introduction. This article is for reference only. I hope it can help you all.
