The first step of growing vegetables is space utilization
For the small balcony of 2 square meters, the first thing to think about is the utilization of space. All kinds of iron and wooden shelves are the basic tools for raising three-dimensional vegetables p>
Specific operation:
Like the position close to the window, the light is good and the utilization rate is high. Two layers of wooden shelves are set, which can be customized with anti-corrosion wood boards. The interior is lined with waterproof cloth and planted with leeks, small peppers and small tomatoes. In order to prevent direct sun exposure and overheating close to the window, reflective and heat-insulating aluminum film can be pasted on the surface close to the window p>
Two rows of movable iron frames can be set on both sides of the balcony. One row of frames is made into a single-layer suspension type, which is used to plant climbing vegetables such as cucumbers. It can simulate the way of greenhouse, and use white thin lines as traction ropes to let vines grow upward along the ropes. A multi-layer partition is made on the side of the shelf to place small potted plants and grow strawberries p>
The other row of shelves can be equipped with multi-layer hydroponic vegetables, which are cultivated in pipes with hydroponic machines, and some leafy vegetables, such as lettuce, cabbage and chrysanthemum. Hydroponic leafy vegetables are planted one after another, clean and soilless, and grow rapidly p>
The second step of growing vegetables is lighting and ventilation
The biggest problem of closed balcony is that the time of sunlight is too short and the ventilation problem is very fatal p>
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 supplement light artificially. Install led fill lights on each row of shelves to increase illumination p>
Ventilation:
If the ventilation is not good, install equipment. Install two solar panels on the top of the window and connect the fans installed at both ends of the shelf to make the whole closed environment in the state of air flow and prevent the balcony from being too hot and humid, which is easy to cause diseases and pests p>
The third step of growing vegetables is the trouble of diseases and pests
Growing vegetables on the balcony can not avoid the breeding of diseases and pests. Some are small insects flying in from the outside, and some may be bacteria or insect eggs carried in the soil p>
For the problem of diseases and insect pests, the most important thing is to often observe, find and deal with them early, remove the plants affected by diseases and insect pests, and prevent them from harming other vegetables. In case of serious insect pests, a small amount of pesticides can be used to eliminate them p>
If we don't want to use the vegetable friends who use pesticides, we can catch the insects manually, hang the insect killing yellow board next to the vegetables, or make our own chili water, choose the particularly spicy red pepper, add water and cook it for half an hour, cool it and spray it on the surface of the vegetables p>
