Soil culture: the preparation of soil culture is to select the soil suitable for the growth of pothos. The soil is as fertile as possible, and most of the nutrition of the pothos comes from the soil. Try to select some soil in the field, mix some animal manure in the soil, and put some small dead leaves in the soil. The pothos likes the soft soil, and the dead leaves and excrement play the role of increasing the soil fertility, softness and permeability.
Hydroponics: Hydroponics is one of the very good hydroponics plants for indoor decoration, climbing and foliage flowers. The stem is soft and the leaves are delicate. Hydroponics is very shade resistant. It can be placed in four seasons in the sunny part of the room. In the dark room, it should be moved to the strong light environment every half month to recover for a period of time. Otherwise, it is easy to increase the internode and reduce the leaves.
Light: the original growth condition of the pothos is that it is not sunny in the forest covered by towering trees. However, in the north of autumn and winter, in order to supplement the deficiency of temperature and photosynthesis, the illuminance should be increased.
Temperature: in the north, if the room temperature is above 10 ℃, the pothos can survive the winter safely. If the room temperature is above 20 ℃, the pothos can grow normally. It is not a big problem for families to reach this temperature. It is necessary to avoid excessive temperature difference and pay attention to keep the leaves away from the heating equipment.
Watering: the watering amount in autumn and winter shall be strictly controlled according to the room temperature. Before heating, the temperature is low and the soil evaporation of plants is slow. To reduce watering, the water volume should be controlled between 1 /4-1 /2 of the original. Even after heating, watering should not be too frequent. Watering should be done less to the basin and should be infiltrated by brown silk. In addition, water should also be sprayed on the air rooting growth place of the brown column to reduce the root water absorption caused by too fast evaporation. The water poured in winter is better than the water dried for a day, and the root is easily damaged if the water is too cold. In water culture, the amount of water should not be too much, just submerge the roots, and the stems and leaves are easy to rot when the amount of water is too much.
Fertilization: in autumn and winter in the north, plants grow slowly or even stop growing, so fertilization should be reduced. Before winter, it is mainly to spray liquid inorganic fertilizer once every 15 days. After winter, foliar spraying is the main way to apply fertilizer, through the stomata on the foliar spraying is the main way, through the stomata on the foliar to absorb fertilizer, the fertilizer effect can directly affect the foliar. Foliar fertilizer should use special fertilizer, ordinary inorganic fertilizer is not easy to be absorbed by foliar. Peking University flower protection God series and Japanese flowers can be used as foliar fertilizer.
Usually, the propagation of the pothos adopts the cutting method. At the end of spring and the beginning of summer, select the robust green wisteria, cut the branches of 15 cm to 30 cm, remove the leaves of 1-2 nodes at the base, pay attention not to hurt the air roots, and then insert them into the plain sand or cinder, the depth is 1 /3 of the cuttings, drench enough water to place in the shade, spray water or cover the plastic film on the leaf every day to moisturize, as long as the environment is not less than 20 ℃, the survival rate is more than 90%.
Common diseases of pineapple: anthrax, root rot, leaf spot.
These three kinds of common diseases are harmful to the leaves of plants and affect the ornamental value. We must observe carefully in the process of maintenance, and timely clean up and spray chemicals in case of any leaf spot.
