Description
Technical Field
The invention belongs to the technical field of prevention and control of diseases and insect pests of pitaya, and particularly relates to a method for preventing and controlling stem rot of pitaya in an internet-of-things greenhouse.
Background
Pitaya, also called red dragon fruit, dragon pearl fruit, etc., is a trigonella plant of the cactaceae family, native to the middle and American tropical desert areas of brazil, mexico, etc., and belongs to typical tropical plants. The pitaya is rich in nutrition and unique in function, the main components of the pitaya comprise protein, dietary fiber, vitamin B2, vitamin B3, vitamin C, carotene, mineral nutrition and various enzymes, particularly plant albumin and anthocyanin which are rare in common plants, the pitaya has the effects of detoxifying, nourishing lung, beautifying and improving eyesight, sesame-shaped seeds in pulp can promote digestion of intestines and stomach, and the pitaya also has the effects of reducing blood sugar, blood fat and blood pressure and the like after being eaten for a long time.
Pitaya stem rot is mainly a disease caused by fungi and is often caused in high temperature and rainy seasons. It mainly damages the basal part of the stem of the dragon fruit or the root of the underground main side, and the surface of the diseased part often forms dark brown sclerotia with different sizes, which begins to be dark brown, and then expands for a week around the basal part of the stem to rot the cortex, and the leaves on the overground part turn yellow and wilted. However, as the root system of the dragon fruit tree has more branches and can not be taken down, simultaneously, pathogenic bacteria can directly invade the uninjured tissue, and the wound can also accelerate infection. Therefore, the stalk rot disease will spread and the whole plant will die later. The occurrence of stem rot of dragon fruits causes great economic loss.
Patent CN104938225A discloses a treatment method of stem rot of dragon fruit, comprising the following steps: A. cutting a diseased dragon fruit tree, scraping a diseased part, cleaning, and then spraying sterilizing medicine, wherein the sterilizing medicine is prepared by carbendazim and agricultural streptomycin according to the proportion of 1: 1; B. b, sleeving the stems of the dragon fruit trees sterilized and disinfected in the step A by using rubber pipes, and fixing the rubber pipes; C. filling a planting base in the rubber tube, and spreading a layer of rice husk ash on the planting base. The method can effectively treat Pitaya tree with stalk rot, and has advantages of no infection source, high cure rate of stalk rot, and no recurrence. However, the sterilizing medicine is short in duration, cannot effectively seal the disease, needs to be isolated by a rubber tube to prevent infection, and is complex to operate; meanwhile, the treatment method only treats the disease and cannot produce effective prevention effect.
