Balcony structure and environment
Most of the building buildings in the city adopt a north-south structure. Generally, there are front and rear balconies, and a few buildings are single-sided balconies. The bonsai is equipped with a south-facing balcony. If the single-sided balcony is not enough, consider adding a certain area within the range of gravity that the balcony can withstand, that is, build a 2~3 ladder step on one or both sides of the balcony, or on the balcony. A metal material empty platform is added to the front edge of the railing.
Balcony bonsai furnishings, to consider the size of the patchwork, layout is appropriate. At the same time, avoid soot and air conditioning directly to the balcony to smudge and discharge, often keep the balcony environment fresh and clean.
Balcony orientation and lighting
The bonsai plants of Xiyang or Banxiyang are generally placed on the balcony in the south or east and west. This orientation is in the spring, summer, autumn and winter seasons, with strong sunlight and more light, which is conducive to the growth of Xiyang or Banxiyang plants. The north-facing balcony has less light and is weak, but it is beneficial to the growth of plants with hi-yin or semi-yin. The illumination of the plants in the south Xiangyang Xiyang takes 6-8 hours per day, while the illumination of the plants in the northward balcony is only 3~4 hours per day. For plants with strong phototaxis, pay attention to the timely replacement of the illuminated surface of the potted plants. Spring and summer, usually replaced once every 30 days, in order to maintain the balanced growth of the branches and leaves of the plant to prevent uneven growth.
Balcony air humidity
Buildings of about 10 floors and above are generally light-filled and have strong sunlight. When the temperature is as high as 36 ° C ~ 37 ° C and the wind reaches 3 ~ 4, the balcony air is dry, the water evaporation of the basin is fast, which is very unfavorable for plant growth. If you are slightly careless, the branches and leaves of the plants will be wilted and even all die. Therefore, we must try to maintain the moisture and air humidity in the balcony, in addition to pouring water into the basin every morning and evening, we must also spray the leaves of the plants 3 to 5 times a day with a sprayer (except for rainy days). At the same time, the balcony floor should be watered 1 or 2 times to create a balcony microclimate.
Strengthen plant water and fertilizer management
Due to the dry climate of the balcony, the water and fertilizer in the potted plants are quickly lost, so it is necessary to maintain the humidity and supplement the nutrients, otherwise it will affect the robust growth of the plants. The demand for water on the balcony is many times higher than the demand on the ground. Water is poured every other day in the spring, once every morning and evening in the summer, once a day in the fall, and once every 2 to 3 days in the winter. In short, we should master the principle of “seeing dry and wet, pouring must be pouredâ€; because of the pots, the plants are large in size, and the basins are shallow and shallow, and cannot be uniform. When fertilizing the balcony bonsai, pay attention to the relationship between the upper and lower sides and the neighbors, and do not pollute the environment. Usually, NPK compound fertilizer or bone powder should be used as potting base fertilizer, and the decomposed thin pizza fertilizer water should be applied. In order to prevent the spread of fat and water odor, some citrus peel or pomelo peel can be placed in the cake fertilizer tank, which can be used as fertilizer and odor, and the fertilizer tank is tightly sealed after application. The liquid fertilizer should be applied after the Qingming period. The plant should be applied once every 10~15 days in the growing season. It should be stopped every 20~25 days after the autumn, and stop fertilizing in the winter dormancy period.
Major pests and prevention
Due to the strong illumination of the balcony, the temperature is high and the pests are relatively high. The author has found that in addition to the triangular insects, such as triangle maple, Chinese mosquito, red nan, and pine, the pots of white wax, water wax, cockroach, firethorn, gold marble, and crape myrtle often occur. Insect pests are scale insects, whitefly, red spiders and aphids. If not controlled in time, the leaves and leaves of the potted plants will be partially wilted and even the whole plant will die. For the above-mentioned pest control methods, use "80% dichlorvos emulsion" and water to dilute 800~1500 times to spray, or use "speed catching killing" or "killing special" liquid plus water 1000~1500 times to spray, the effect is very good. For locusts sprayed with tobacco water 2~3, you can kill them all.
