Recently, some vegetable farmers have reported severe stem-based rot after vegetable colonization. Through field investigations, it was found that this disease has a lot to do with the current high temperature environment and the improper management of vegetable farmers. In this regard, the author reminds the majority of vegetable farmers to pay attention to three points in the management of the greenhouse planting period in the autumn. First, pay attention to increase the amount of organic fertilizer and biological fertilizer Many vegetable farmers have reported that more and more fertilizers are being invested, and vegetable production is getting lower and lower, which is related to the unreasonable use of fertilizer by vegetable farmers. Due to the long-term large-scale application of chemical fertilizers and the neglect of the application of organic fertilizers, the accumulation of salt in large-scale cultivation in successive years is not conducive to the growth of vegetables, and the activity of beneficial microorganisms in the soil is reduced or even died. The imbalance of soil microorganisms causes serious root diseases, resulting in serious diseases. Vegetable yield is low and quality is poor. Before the vegetable is planted, the vegetable farmers should pay attention to increase the amount of organic fertilizer. Deep application of organic fertilizer can increase the content of organic matter in the soil, promote the formation of soil aggregate structure and increase the permeability of the soil. In addition, vegetable farmers should also pay attention to increase the amount of biological fertilizer. Biological bacterial fertilizer can increase the number of beneficial microorganisms in the soil, inhibit the occurrence of soil-borne diseases, and at the same time promote rooting, which is conducive to the formation of strong vegetables and increase the yield in the later period. Second, pay attention to reduce the amount of fertilizer When planting the former crops in the greenhouse, the application amount of organic fertilizer is often more, and the amount of fertilizer in the later period is larger. In this case, when the vegetables in the greenhouse are delayed in autumn, the amount of chemical fertilizer should be reduced or no fertilizer should be used. In high temperature weather, the solubility of chemical fertilizer in the soil is very high, coupled with the high salt content in the soil, excessive application of chemical fertilizer is not conducive to the growth of vegetable roots. Third, pay attention not to the whole shed black mulch In the current situation, some seedling problems are often caused by improper coverage of vegetable farmers. The environmental conditions in the late summer and early autumn are conducive to the growth of vegetables, as well as the growth of weeds. In order to prevent weeds between plants, many vegetable farmers will cover the black mulch after colonization. The temperature under the mulch film is very high, and a large amount of water vapor volatilizes from the base of the stem, which easily burns the base of the stem of the vegetable and creates an opportunity for the infection of the pathogenic bacteria. At present, many eggplants planted in the vegetable vines appear close to the surface of the stalk becomes thinner and darker, and the severe dry death is caused by the infection of the stem-based rot pathogen. It is the black mulch that burns the base of the eggplant stem and induces the occurrence of the disease. Therefore, if the black mulch film should not be connected at present, it should be kept at a certain distance from the base of the plant stem and pressed around the stalk to prevent hot air from being discharged therefrom. If the temperature in the shed is too high, it is not recommended for the vegetable grower to cover the mulch film, and the mulch film can be covered after the high temperature.
