Watermelon cultivation is the most irritant to heavy scorpions, and heavy sorghum will cause the watermelon plants to grow weak, susceptible to disease, and when severe, can cause a significant reduction in production. In particular, in areas where there have been diseases such as blight, anthrax, epidemics, and bacterial keratoses, replantation will increase the degree and probability of occurrence of the disease. So, how to properly control the occurrence of watermelon rickets? Recently, reader Liu Xiyuan, Xiaopo Village, Anren Town, Dayi County, Weinan City, Shaanxi Province, made a telephone call to consult the issue. The reporter interviewed Zhang Xian, a professor of horticulture at the Northwest A&F University and a tutor of vegetables, and he gave the following points to growers. Suggest: 1, the selection of disease-resistant varieties in the cultivation of watermelon, it is best to use some varieties of anti-grass cultivation, to reduce the incidence of diseases caused by double-double. 2. Staggering the planting line for planting watermelons should be in a staggered position with the planting line in the previous year. The distance is 60 cm or more. After the harvest of watermelons in the year, we must promptly clean up the vines and melon roots. When arranging for other crops, it is best not to disturb the soil where the original watermelon is oriented. When cultivating the land, be sure to mark it so that the soil of the original watermelon is not mixed with the soil left as the watermelon of the year. 3. Grafting Cultivation Grafting cultivation is an effective measure to avoid the occurrence of diseases caused by watermelon cultivars. Grafting with gourds, squash, etc. as rootstocks can prevent the occurrence of disease caused by double pods. At the same time, Professor Zhang Xian said that by adopting the method of grafting and cultivation, it will have a certain impact on the quality of watermelon when it comes to controlling the diseases of watermelon. It is even more important to use pumpkin as rootstock. 4. The improved soil is applied organically in the ground and soil bactericidal agents are used for soil sterilization. According to the current market budget, the use of soil fungicides in watermelon fields will result in an investment of 500 yuan per mu. In addition, Professor Zhang Xian reminded the majority of growers, planting watermelons, as far as conditions permit, as much as possible, so as to prevent disease.
