The breeding methods and precautions of the twelve roll genusThe plants of the twelve scrolls genus are mostly found in the cold coastal desert areas of Cape Province in southern South Africa. Frequently located in the Atlantic and Indian Oceans, with little rain and fog throughout the year, a small amount of rainfall occurs in winter, with an average temperature of 12 ℃ -15 ℃, similar to our spring and autumn seasons, so this is their peak growing season. A part of the current cultivation is through horticultural or cultivated varieties, and the breeding conditions are relatively more relaxed.1. Selection of Flower Pots:The root system of the twelve roll genus is more developed than other genera, so it is best to choose a deep basin with a height greater than the diameter of the basin, and the material is preferably a highly breathable mud tile or ceramic basin. However, household farming appears too bulky and unattractive, so resin, ceramic, or plastic pots can also be used on the premise of increasing the permeability of the medium. The plastic basin has become the first choice for family breeding because of its light weight, anti-aging and low price.2. Soil selection:According to the convenience of different regions, peat soil, peat soil, or saprophytic leaf soil rich in humus can be used for sampling; Breathable lightweight materials such as crushed red clay, river sand, weathered mountain sand, red jade soil, light stone, blue stone, perlite, etc; Mix rice husk charcoal, plant ash, and other materials rich in phosphorus and potassium in a ratio of 3:6:1 for breathability and water retention. If possible, add a small amount of calcium containing eggshell powder, bone powder, shells, or coral powder (be sure to wash repeatedly to remove salt). Sieve off the dust, with a particle diameter of 0.5-3mm. Depending on the humidity of the planting environment, the breathability of the pot, and personal planting habits, add or subtract the proportion of humus or lightweight materials.3. Water source requiThe tap water can be dried for a day, but it is best to use soft water such as rainwater.4. Lighting requirements:Originally, it was mentioned that the twelve scrolls belong to the category of half shade, but in fact, this is not the case. In the case of healthy root systems, full sunlight can be gradually applied from late autumn to early summer. In late summer and early autumn, there is strong sunlight. To prevent burns, appropriate shading can be used, such as a 50 {bf} shading net or two layers of window screen. A small amount can be covered with one or two layers of tissue paper on a single plant (this method can also be used to slow down the adaptation period of newly purchased plants).5. Air requirements:Air is often overlooked by people, and in fact, fresh air circulation is important for increasing plant disease resistance and reducing pest infestation (so some plants in closed or enclosed greenhouses often have cracked or shrunk window surfaces when changing the environment)6. Fertilization control:Twelve rolls are not fond of fertilizer. If changing pots every year, fertilization is not necessary. During the spring and autumn growth period, thin phosphorus and potassium liquid fertilizers (fermented beer, cooked fish scales, bone meal water, etc.) can be applied two or three times. If you don't plan to change pots every year, you can bury a small amount of manure from cows, chickens, birds, and other poultry at the bottom when planting, but it must be fully decomposed and fermented, and strictly sterilized and disinfected. Inorganic fertilizers can cause plant dependency and are not recommended for use.7. Potting and planting:Although most of the twelve roll genus is a winter type species, family farming nowadays does not have deep dormancy except for short periods of extremely high temperatures in winter and summer, when growth is basically stagnant at extremely low temperatures (short-term temperatures as low as 5 ℃ and maximum temperatures as high as 40 ℃ can grow). Therefore, it is be8. Daily management:The best placement for plants of the twelve roll genus is on a south facing balcony or windowsill, where sunlight is most ideal from the top. This is often not achieved by family farming, and the windowsill also receives oblique light. In this way, to prevent the phototaxis of plants, it is necessary to regularly rotate the flowerpot. Fortunately, they grow slowly and can rotate once every half month during their growth period. But ensure at least two hours of light every day. Watering, choose a sunny morning in spring, summer, and autumn, and a sunny noon in winter.9. Treatment and prevention of pests and diseases:The 12 roll genus is relatively robust, with relatively less occurrence of diseases and pests. The main diseases are root rot or leaf rot. If discovered early and timely, removing the rotten leaves or roots for sterilization and disinfection, and drying them in the sun often does not cause plant damage, and is generally not easy to infect. Some hard leaf 12 roll genera also have dry tips when their roots are intact and the humidity is suitable. This seems to be a natural phenomenon rather than a disease. Occasionally, there are red spiders and nematodes, and insecticides can be sprayed if found. However, based on the principle of prevention first and prevention in advance, it is best to mix insecticides such as furan in the soil of the pot, and regularly spray insecticides such as mopuzin, carbendazim, and betamethasone zinc (during the growth period of half a month).$3.38
