Cape Jasmine is originally produced in China and cultivated in most parts of the country. It is concentrated in most areas of eastern China, southwest and central and central China, including Fujian, Guizhou, Zhejiang, Jiangsu, Jiangxi, Hubei, Hunan, Sichuan, and southern Shaanxi provinces. The city Flower of Changde in Hunan province is Cape Jasmine. The city flower of Yueyang in Hunan province is Cape Jasmine.
Cape Jasmine likes a warm, humid, well-lit and well-ventilated environment, but it is not exposed to strong light. It is suitable for living in a slightly shaded place, tolerant to semi-shade, afraid of standing water, and cold resistant. In northeast, north and northwest China, Cape Jasmine can only be used as greenhouse potted flowers. Cape Jasmine is suitable to use loose fertile, good drainage of light viscous acid soil planting, is a typical acid flower. It can be propagated by cutting, layering, dividing or sowing.
Cape Jasmine is an indicator plant for acidic soils, so the slightly acidic environment of the soil is the key to the growth of Cape Jasmine. The culture soil was a mixture of slightly acidic sandy laterite and leaf saprolite. It is advisable to control the pH value of the soil between 4.0 and 6.5.
The optimum growth temperature in Cape Jasmine is between 16℃ and 18℃. Low temperature and direct sunlight are extremely detrimental to the growth of Cape Jasmine. Therefore, it is advisable to conserve Cape Jasmine in the open forest or shade shade with good ventilation, high air humidity and transparent light in summer. Winter in the sun, the temperature is not lower than 0℃ environment, let it dormant, the temperature will affect the next year's flowering.
Cape Jasmine likes humid air, and water should be added moderately during the growing season. Usually the basin soil can be white water, thoroughly pouring. Summer is hot, every day to foliar spray 2-3 times, in order to increase air humidity, help plants cool down. But after the flower is bud, watering should not be too much, so as not to cause falling bud.Winter watering with partial dry had better, prevent water root rot.
Cape Jasmine is a fat-loving plant. In order to meet its growing needs and maintain a slightly acidic soil, Ferric Sulphate can be mixed into the fertilizer solution for fermentation. After entering the growth season in April, we can apply top dressing every half a month (fertilization when it is best to add some water, in case of burning). This will not only meet Cape Jasmine's needs for fertilizer, but also keep the soil in a relatively balanced acidic environment to prevent the occurrence of chlorosis, as well as avoid the damage to Cape Jasmine caused by accidental ferrous sulfate supplement and local excessive acid.
Cape Jasmine is frequently prone to leaf yellowing and leaf spot, which is sprayed 600 times with 65% Zinc WP. The insect pests were acanthophora moth, scale insect and mealworms. The acanthophora moth was sprayed with 2.5% enemy killing emulsion 3000 times, and the scale insect and mealworms were sprayed with 40% oxidized dimethoate emulsion 1500 times.
The occurrence is more common, caused by a variety of reasons. It is necessary to take different measures to prevent and control the general application of decayed human excrement or cake fertilizer.
Young leaves between the veins of the loss of green and yellow, seriously will make the whole plant leaves yellow, and even coke leaves and branches withered, and finally cause the plant death. In this kind of situation, we can spray 0.2% ~ 0.5% ferrous sulfate aqueous solution for prevention and control. The chlorosis caused by magnesium deficiency gradually develops from the old leaves to the new leaves, and the veins are still green. In severe cases, the leaves fall off and die. In this kind of situation, we can spray 0.7%, 0.8% boron magnesium fertilizer prevention and control. Overwatering, freezing and so on, will also cause the phenomenon of yellow leaves, so in the maintenance process to pay special attention to. The appearance of nitrogen deficiency is simple yellow leaves, and the new leaves are small and crisp. Potassium deficiency appears as the green to brown color of old leaves. Phosphorus deficiency is manifested as purplish red or dark red in old leaves.
Soot disease occurs in branches and leaves. After discovery usable clear water is swabbed, or gush 0.3 wave beauty spends stone sulfur mixture, 1000 ~ 1200 times much fungus is clever.
Rot often occurs in the lower trunk, stem bulging, cracking, immediately after the discovery of scraping or coating 5 ~ 10 degrees of sulfur mixture, several times can be effective.
The pests that plague Cape Jasmine are aphids, hoppers and horsetail moth larvae, the first two of which can be controlled by dimethyl fruit and trim trites, the latter of which can be controlled by 666 powder or captured manually.
Pest and disease control in Cape Jasmine. In addition, in the winter of Cape Jasmine, when the indoor ventilation is poor and the temperature and humidity are too high, the harm of scale insects is prone to occur, accompanied by the occurrence of soot disease. Scale insects can be scraped off with a Bamboo stick or a small brush, and can also be sprayed with 20 oil emulsion plus 100 ~ 150 times water. Soot disease can be swabbed with clear water, or with polyfungalim 1000 times liquid spray prevention and control.
