Cash cows can grow well in bright or dark places. In summer, we should keep high air humidity and pay attention to shade. In winter, we can keep a relatively dry environment, but we need bright light. The cultivation medium of cash cow is fertile, loose, rich in organic matter, good in air permeability and strong in water and fertilizer conservation, but the slightly acidic soil without water accumulation is the best, and compound fertilizer is applied once a month during the growing period. Propagation can be carried out by sowing, lobular cutting and tissue culture.
Cash cows grow faster and need pruning from time to time, otherwise they will always grow vertically, especially the newly cut seedlings, which will grow into an army without topping and pruning. The cut branches can be used for cutting, otherwise it will be wasted. Cutting is the easiest way to cultivate cash cows.
One of the keys to the survival rate of cash cow cuttings is the selection of branches: the branches are required to be lignified. Semi-lignified branches have more water and less nutrition, and even in clean vermiculite, they are easy to rot and difficult to take root. Newly grown branches generally need to grow for more than 8 months before they are suitable for cutting. Of course, the longer the time, the safer. After cutting the cash cow, it is best to cover the basin with a white or transparent plastic bag to keep it warm and moist. Generally, it can take root after 2 ~ 6 weeks, and seedlings can be transplanted after 1 ~ 2 weeks. Cash cows are planted in flowerpots with loose and fertile soil and covered with plastic bags to keep warm and moist. It can grow rapidly under sunny windows.
Cultivation method of potted cash cow
Cash cow likes warm, high humidity and smooth air environment. Put them indoors with heating equipment in winter, but the potted plants should not be too close to the radiator. In summer, if the temperature exceeds 30℃, they can be moved to a ventilated room near the north. * If the topsoil in the basin is not dry, it will be watered thoroughly. If there is water seepage, it is advisable to keep the air humidity relatively high. Foliar spraying can be used, and tap water can be used for irrigation. Tap water had better be dried in the sun for half an hour.
There is no special requirement for the soil in cash cow cultivation, just the general soil, and the loose and breathable soil is even better. Potted cash cow soil can be mixed with 1 peat soil, 1 garden soil and 1 river sand, and cake fertilizer can be applied as base fertilizer. In the growing season, water and fertilizer should be sufficient to keep the basin soil moist. In summer, besides wetting the substrate, water should be sprayed on the leaves and the ground, and thin fertilizer water, mainly nitrogen fertilizer, should be poured every 65438+ 10. In summer, properly block the cash cow and avoid direct glare. The overwintering temperature must be kept above 10℃, and long-term low temperature will cause root rot.
Cash cows love light, and they can receive direct light all year round in the north. You can leave your room after Qingming every year and put it in the open air without shading. It is best to put it under a sunny window in winter. If the conditions are right, this period is the peak season for the growth of cash cows.
Water the cash cow, or dry it and then water it thoroughly. Fertilization can be combined with watering, and soaking solution such as cake fertilizer (sesame sauce residue) and organic fertilizer can be used in summer. In summer, if you put the cash cow outdoors, you can accept the rain and dew, and you don't need to care about the pH of the water. Pay attention in winter, because tap water is weakly alkaline. Generally, after watering with tap water, it is better to soak the diluent with orange peel every 2 ~ 4 times. It is best to spray water 1 time every day in winter, because the temperature under the indoor sunshine window can reach more than 30 degrees at noon, and the room will be drier after heating.
Matters needing attention
1. After summer, move the cash cow to a semi-cool environment in time. If it rains for a long time in late spring and early summer, plant pots as soon as possible to shade it.
In the hot summer, or after a long period of rain in Chu Qing, or a cash cow that has just moved outdoors for restoration maintenance, it is easy to cause its fat and tender leaves to be directly burned by the sun, resulting in some of its leaves losing their green and white, or the whole leaves are burned, and the necrotic parts in the later stage will turn brown and black.
2. During the winter of cash crops, the greenhouse temperature should be kept not lower than 65438 00℃, and the basin soil should be kept slightly dry.
When the temperature drops below 5℃ in winter, the soil in the basin is wet, which is easy to cause the tender leaves of cash cow to fall off due to cold, and in severe cases, it will cause tuber rot and it is difficult to restore vitality.
