Description

An intelligent planting device for greenhouses that effectively utilizes sunlight

technical field

This patent relates to the technical field of solar greenhouses, in particular to an intelligent planting device for greenhouses that effectively utilizes sunlight.

Background technique

Facility agriculture in my country has developed rapidly in the past ten years, but it is mainly plastic greenhouses, which have small unit area, low height, large heat dissipation area, and low sunlight and land utilization rates. Especially in winter, greenhouses need to be heated to prevent freezing, which consumes a lot of energy. With the adjustment of my country's agricultural industrial structure, solar greenhouse planting has been paid more and more attention by the government and farmers. With the rise of aeroponics technology, it is different from the traditional planting method of planting vegetable crops in the field, and is suitable for solar greenhouses. The planting device came into being.

In most parts of northern my country, solar greenhouses are widely used as the main agricultural production facilities. However, the intensity and duration of solar radiation generally decreased in spring, autumn and winter in these regions. Less light time and light intensity will affect the normal growth of crops in the solar greenhouse. In order to improve this situation, it is necessary to adopt suitable methods to make more efficient use of daylight.

Chinese Patent No. 201020239688.6 describes a kind of greenhouse external-mounted reflective curtain. This kind of greenhouse external reflective curtain includes at least one reflective plate, fixing device and bracket arranged above the greenhouse. The reflective curtain uses the way of reflecting sunlight to add light to the greenhouse. However, the building height of the ridge of the solar greenhouse is usually more than 2.6 meters. Its structural size must be larger than that of the greenhouse, and the manufacturing cost is high, which also affects the lighting of the solar greenhouse in the back row.

Chinese Patent No. 201020175025.2 describes a multi-span energy-saving solar greenhouse. This multi-span solar greenhouse is connected by a group of single-slope solar greenhouses arranged in front and back. Two rows of symmetrical support columns are arranged between adjacent solar greenhouses, and shed boards are installed on the top of the support columns. However, connecting adjacent single-slope greenhouses into one will complicate the watering and other systems of the solar greenhouse, and it is also not conducive to the insulation of the greenhouse in winter.
