Description

Distributed Smart Plant Factory

technical field

The invention relates to modern agricultural technology, in particular to a distributed intelligent plant factory.

Background technique

At present, my country's land use area is gradually decreasing. In order to meet self-sufficiency, the planting industry is facing severe challenges. Agricultural technicians can only relieve the pressure of land tension through soilless cultivation.

The existing plant hydroponic technology is basically outdoor planting, river planting, lake planting, etc., which can also ensure the normal growth of plants, but the normal sunshine time of about 8 hours is far from enough, and they all rely on the natural environment Therefore, it is difficult to determine the control of the environment, and the growth period of plants or vegetables cannot be effectively shortened. In order to reduce heavy agricultural labor, agricultural planting has evolved into automated plant factory planting. Increase the land utilization rate by 100-200 times, save water consumption to one-fiftieth of land planting, and reduce the heavy labor processes such as plowing, watering, weeding, fertilizing, and spraying, and realize the single labor force The annual planting volume of 50 mu of land is far away from smog, pesticides, and pests, so as to realize the factory planting of safe, green, nutritious and delicious food and vegetables.

Applying the concept of automation to agricultural vegetable planting, the heavy agricultural labor has evolved into a modern factory automated production form, and the problem of insect pests and pesticide residues has been completely solved, setting a new benchmark for future modern agricultural planting.

But, the soilless cultivation technique in the prior art still has many deficiencies in operation:

1) The space utilization rate is not high, and a large floor area is still required;

2) Generally, the mode of unified planting and unified harvest is adopted, which has relatively high requirements for the consistency of environmental elements in the entire space, and cannot realize the continuous supply of cultivated products, especially vegetables;

3) The full artificial lighting system uses direct lighting, and the lighting time and wavelength cannot be precisely controlled, resulting in the inability to create the most suitable lighting conditions when planting different plants;

4) The lack of a corresponding wind circulation system cannot simulate the wind blowing effect in nature, so that the leaves of the plant will not sway during the growth process, affecting its transpiration effect, which is not conducive to its growth;

Therefore, there is an urgent need for a plant factory system that can solve the above problems, so as to facilitate large-scale and industrialized planting of plants, so as to alleviate the pressure on the land.
