After the serious illness of vegetables has been restored, how do you manage?
After a serious vegetable disease, the body is often weak. Although the disease is cured, the maintenance of the latter stage is still very important. If the maintenance is not good, the vegetables will be re-infected on some day. Therefore, after the rejuvenation of vegetables, we must take care of them and promote them from weak to strong as soon as possible. So how do you do in production? Li Zhenhua, a master of Baocheng Street in Changle County, is very insightful. Below, we may wish to listen to his views. Master Li introduced that when vegetables are seriously ill, they are nursed back to health. Therefore, the entire management process should be based on raising trees. Specific starting from the following three aspects: First, leave little fruit, and promote the return of trees. Master Li said that after a serious illness in vegetables, the plants must be able to “do less work†if they want to resume growth as soon as possible. Therefore, the fruit should not be too much in this period. It should be determined according to the plant growth. If the plant growth is weaker, it can be less. If it is weak, it will not be left. It will directly remove all the fruits and completely reduce the burden on the plants. Apply fertilizers with high nitrogen content to accelerate the vegetative growth of plants and promote their return to the trees as soon as possible. The second is to skillfully use plant growth regulators to lift the leaves. Master Li said that when the vegetables are seriously damaged, the plants often stop growing or grow poorly. If the roots are damaged, the plants will be accompanied by falling flowers and fruits while the melons and vegetables will appear to have melons or flowers topping. Therefore, the vegetables should be promptly overgrown with foliar sprays, such as oversupply, and Yunda 120, after the disease has recovered, and can be used to supplement the leaf nutrients with Fangrun or Qingniye fertilizer to increase the photosynthetic capacity of the leaves. This promotes better plant recovery. The third is using living biological bacteria fertilizer. Master Li stressed that the use of bio-fertilizer should be emphasized after a serious illness in vegetables. He said that biological bacterial fertilizer can inhibit the proliferation of pathogens, improve soil structure, and improve the rhizosphere environment of vegetables. It is a good fertilizer for root and root culture. Therefore, the timely application of bio-fertilizer after the re-emergence of vegetable diseases has a significant effect on the promotion of strong vegetables. For example, 20-25 kilograms of antimicrobial 968 biological fertilizer is applied per acre, which not only effectively promotes root growth and plant rejuvenation, but also has a very significant effect in preventing the occurrence of root diseases. In addition, Master Li added that in this special period, we must regulate and control the temperature and humidity in the shed, ensure sufficient lighting in the shed, and timely top-dressing and watering, and plan the loosening of the soil so that the vegetables can quickly be strong. stand up.
