Description

Hanging bag planting shed

Technical Field

The invention relates to the field of agricultural production, in particular to a hanging bag planting shed suitable for arid and plateau areas.

Background

In arid desert areas, the air humidity is low, the water evaporation capacity is large, the drought is short of water, the temperature is high in the daytime and the night is cold, and crops are difficult to survive when being planted in a traditional mode; in plateau areas, the loss of various inorganic salts in soil and low atmospheric carbon dioxide concentration are caused by the rain wash for tens of thousands of years, and the soil is not suitable for the growth of crops. The existing agricultural planting mode is used for planting crops in arid areas and plateau areas, the crops are difficult to survive, and even if the crops survive, the crops are difficult to harvest. Therefore, arid regions and plateau regions are desertified, and large flat lands are left, so that the land can not be effectively utilized.

Disclosure of Invention

The invention aims to provide a hanging bag planting shed which is not afraid of loss of nutrient substances in soil; reducing evaporation of irrigation water; the proper temperature and humidity of the growth environment of the crops are guaranteed, the capability of the roots of the crops for absorbing carbon dioxide is fully exerted, and the crops can thrive in dry deserts and cold plateaus.

In order to realize the purpose of the invention, the following six basic measures are adopted, and a punching bag planting shed suitable for arid and plateau areas is provided:

A. local soil is not needed, and a hanging bag filled with nutrient medium and nutrient solution is adopted for planting, so that the problem of soil nutrient loss is solved;

B. the flat and breathable hanging bag with the increased specific surface area is adopted for hanging planting, so that the crop root system is convenient to contact with air, and the capability of absorbing carbon dioxide by the crop root is fully exerted;

C. because the solubility of carbon dioxide in water is three thousand times of that of the atmosphere, the humid environment is more beneficial to the absorption of the carbon dioxide by crop roots, and therefore, the water storage area is arranged below the hanging bag, the humid environment in the hanging bag is ensured, and meanwhile, the nutrient substances are prevented from losing along with rainwater;

D. because the carbon dioxide solubility of water is more than three thousand times of air under the same air pressure, the invention arranges the vent pipe in the water storage area of the punching bag and adopts the air pump to pressurize and convey air to water and nutrient solution; the dissolution of carbon dioxide in the air into water is accelerated, and more carbon dioxide is provided for the photosynthesis of crops;

E. because the temperature in the hanging bag planting shed is determined by the absorption of sunlight, the reflection rate of the shed film is improved, the temperature in the shed can be reduced, and the temperature suitable for the growth of crops in the shed is kept. Therefore, in hot summer, the temperature in the hanging bag can be greatly reduced by the reflective shed film in the daytime, and the evaporation of water is reduced; at night, the reflective shed film can reduce heat loss caused by heat radiation and preserve heat of the planting shed.

F. The planting shed can prevent water vapor from rising upwards, improve the relative humidity in the shed, greatly reduce the evaporation of water in the shed and save irrigation water.

The hanging bag planting shed constructed according to the measures can guarantee nutrient substances required by the growth of crops, greatly enhance the carbon dioxide absorption capacity of the crops, improve the photosynthesis efficiency of the crops and reduce the evaporation of irrigation water; the temperature and the humidity suitable for the growth of crops are ensured, and the crop yield is increased.

Detailed Description

As shown in attached figures 1 and 2, the hanging bag planting shed comprises a planting hanging bag 1, wherein a nutrient medium 3 and a nutrient solution 4 are arranged in the planting hanging bag 1, the planting hanging bag 1 is suspended by a water pipe 6, a waterproof coating 2 is arranged below the inner part of the planting hanging bag 1, and a vent pipe 7 is arranged; the water service pipe 6 is arranged on the support 9, and is characterized in that the support 9 supports a shed film 10, and the shed film 10 covers the whole planting shed.

The shed film 10 is made of transparent high polymer plastic or fiber fabric, and the outer surface of the shed film is coated with a reflective film or sprayed with a reflective material, so that the shed film can partially reflect sunlight and reduce the temperature in the shed; in hot areas, the shed film 10 has high light reflection rate and low light transmittance; in cold regions, the greenhouse film 10 has low light reflection rate and high light transmittance.

The lower part of the shed film 10 is open, the top and the side surfaces are basically closed, so that the water vapor in the shed can be prevented from rising and escaping, the relative humidity of the air in the shed can be increased, the evaporation of the water in the planting hanging bag 1 can be reduced, and the high-temperature dehydration of the crops 5 can be prevented.

The top of the shed film 10 is concave and permeable, and can guide rainwater and distilled water to flow to the planting punching bag 1.

The planting punching bag 1 is made of porous film or fiber fabric, the upper half part is permeable to water and air, the lower half part is provided with a waterproof coating 2 to form a water storage area 13 which can store nutrient solution 4 and water, and the proportion of the upper half part and the lower half part is determined by the habit of crop root systems.

An air pipe 7 is arranged in a water storage area 13 at the lower part of the planting punching bag 1, the air pipe 7 is made of air-permeable porous membrane materials or fiber fabrics, the air pipe 7 is connected with an air pump 11, and pressurized air is conveyed into the water storage area (13) below the planting punching bag 1, so that carbon dioxide in the air is fully dissolved into water; the air pump 11 can also be used for pressurizing and delivering carbon dioxide gas directly, and more carbon dioxide can be filled into the water storage area (13) through the vent pipe 7.

The outer surface of the hanging planting bag 1 is highly reflective, so that the weeds cannot be subjected to photosynthesis, and the growth of the weeds in the bag is inhibited.

The water pipe 6 is connected with a water pump 12, and the water pipe 6 is provided with a drip irrigation hole to supplement nutrient solution 4 and water for the planting punching bag 1 in a drip irrigation mode.

Planting holes 8 are formed above the planting punching bags 1, and crops 5 are planted in the planting punching bags 1 through the planting holes 8.

The planting punching bags 1 can be hung on the bracket 9 in layers, so that the planting space can be fully utilized for three-dimensional planting.
