Method for growing crops on roof

technical field

The invention belongs to a method for cultivating crops, in particular to a method for cultivating crops on a roof.

Background technique

Our country has abundant roof resources. The roof has sufficient temperature and light resources, and the air is dry and circulates quickly. Using the roof to cultivate crops can not only effectively isolate diseases, insect pests and weeds, but also easily obtain high-yield and high-quality agricultural products. It is the preferred place for efficient crop cultivation. However, due to the lack of related technologies for using roofs to cultivate crops, when people use roofs to cultivate crops, they will cause crop death, high cultivation costs, damage to the sanitation environment, and impact on roof safety due to incorrect watering and fertilization and improper management. Taking advantage of failures may even arouse social resentment.

People have been paying attention to the utilization of roofs for a long time, and have carried out research on the production of cultivation ponds, the selection of cultivation substrates, and suitable cultivation of plants. The Chinese patent document with the application number CN201320417527 discloses a cultivation device, which consists of a cultivation box with a small top and a large bottom, a water storage tank and a water pump.
