2 square meters of small balcony, the first problem to think about is the use of space, all kinds of iron, wood shelves are the basic tools to raise three-dimensional vegetables.
Specific operation:
Like the position near the window, with good lighting and high utilization rate, two layers of wooden shelves can be set up, which can be customized with anticorrosive wood boards, with waterproof cloth as the inner lining, and planted with leek, pepper and tomato. In order to prevent the adjacent window direct sun overheat, can be near the window surface paste reflective insulation aluminum film.
Two rows of movable iron shelves can be set on both sides of the balcony. One row of shelves is made into a single-layer hanging type, which is used to plant climbing vegetables such as cucumbers. It can simulate the way of greenhouse, use white string as the traction rope, and let the vines grow up along the rope. The side of the shelf is made with multi-layer partition board, which is used for placing small potted plants and planting strawberries.
Another row of shelves can be equipped with multi-layer hydroponic vegetables, which are cultivated by hydroponics machine and pipes, and some leafy vegetables, such as lettuce, cabbage and chrysanthemum. Hydroponic leafy vegetables, one after another, clean and soilless, grow rapidly.
The biggest problem of closed balcony is that the time of sunshine is too short and the ventilation is very fatal.
Illumination:
Living in buildings and small balconies, it is impossible to achieve more than 10 hours of natural light every day, but in order to meet the growth needs of plants, we can carry out artificial lighting. Install led fill light on each row of shelves to increase the illumination.
Ventilation:
If the ventilation is not good, install the equipment, install two solar panels on the top of the window, connect the fans installed at both ends of the shelf, so that the whole closed environment is in the state of air flow, to prevent the balcony from high temperature and humidity, which is easy to cause diseases and insect pests.
Planting vegetables on the balcony can not avoid the breeding of diseases and insect pests. Some are small insects flying in from the outside, some may be bacteria or eggs carried in the soil.
In view of the problem of diseases and insect pests, the most important thing is regular observation, early detection and early treatment, which will remove the plants suffering from diseases and insect pests and prevent the continuous harm to other vegetables. In case of serious insect pests, in order to eliminate them, a small amount of pesticides can be used.
If you don't want to use pesticides, we can catch insects by hand, hang a yellow board beside the vegetables, or make chili water by ourselves, choose the hot red pepper, boil it with water for half an hour, air it and spray it on the surface of the vegetables.
