Autumn is a transitional period from jasmine to dormancy. If it is properly maintained during this period of time, the xylem of the plant will be enriched and the water content will be reduced. This will lay the foundation for safe wintering; if it is not properly managed, it will easily lead to plant growth or stop growing. It is conducive to safe wintering, and even affect the flowering in the coming year. According to the author's experience, the following five points should be made for the management of jasmine in the fall: 1. The light is bright enough for jasmine. In the autumn, the jasmine should be moved from the half shade to a sunny place to support the plants. In this way, the leaves can better carry out photosynthesis, supply the nutrients needed for the growth of shoots in time, and promote the maturation of new shoots in the year to make it safe for winter. Second, suitable for water and fertilizer Early autumn, especially in mid-September, the temperature is still high, large transpiration of plants, this time the water is easy to make the leaves dry, and even dead branches, it takes 1 to 2 days to once pervious. From the end of September to the time of admission, the temperature dropped and the evapotranspiration of the plants decreased. The water can be poured every 3 to 4 days. To fertilize jasmine in autumn, it should be gradually reduced. During the flowering period (from September to October), translucent sesame sauce water should be poured once a week. After the end of flowering period, a single application of phosphorus and potassium fertilizer can stop the fertilizer. If the fertilizer is not stopped, it is easy to make plants. excessive growth. Third, the control of insect pests is another epidemic period of jasmine pests in autumn, when plants are vulnerable to scale insects, spider mites and aphids. If there is a small amount, it can be removed manually; when the amount is large, 40% omethoate EC can be sprayed to kill locusts and red spiders 1000 times, and the scale insects are sprayed with 1200 times 80% dichlorvos emulsion. Fourth, properly trimmed jasmine should be properly pruned before entering the room in the end of autumn, mainly to cut the branches and branches of pests, thin branches, dried branches in time. For the beautiful appearance of the plant, the pendent shoots and endophytic branches should also be cut off. V. Temporarily enter the room at the end of autumn, when the temperature is lower than 12°C, it should be promptly admitted to prevent frost. After entering the air, place it in a well-lit place and pay attention to ventilation. China Agricultural Network Editor
