A multifunctional agricultural plastic film greenhouse and its application method

Abstract

The invention relates to a multi-functional agricultural plastic film greenhouse and its use method, comprising a mounting frame, an adjusting device and a supporting device, an adjusting device is installed in the middle of the mounting frame, supporting devices are symmetrically installed on the left and right sides of the mounting frame, and the adjusting device is located in the middle of the supporting device . The present invention can solve the following problems in the current agricultural seedling raising process of plastic film: the temperature in spring and autumn is suitable, and proper ventilation in the greenhouse is required; the temperature in summer is too high, and a large area of ​​ventilation in the greenhouse is required; If the temperature is too low, the greenhouse needs to be airtight and insulated. In order to ensure that the temperature in the greenhouse is suitable for the growth of crops, the ventilation of the greenhouse is realized by manually rolling the film, and the construction and dismantling of the plastic film greenhouse requires manpower, and each use is laborious. It is necessary to rebuild the skeleton of the greenhouse and then cover it with plastic film. Due to the large planting area of ​​the crops and the manual roll-up of the film for ventilation, the labor intensity is high and the efficiency is low.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouses, in particular to a multifunctional agricultural plastic film greenhouse and its application method. Background technique [0002] Plastic greenhouses make full use of solar energy, have a certain heat preservation effect, and can adjust the temperature and humidity in the greenhouse within a certain range through the roll film. Therefore, in the northern region of my country, plastic greenhouses mainly play the role of heat preservation and cultivation in advance of spring and delay in autumn; The shading net is used for shading and cooling in summer and autumn and for rain, wind, hail and other facility cultivation; [0003] At present, in the process of agricultural seedling cultivation of plastic film, due to the limitation of the composition and structure of the plastic film, there are the following problems in the actual operation process: the temperature in spring and autum...

Problems solved by technology

[0003] At present, in the process of agricultural seedling cultivation of plastic film, due to the limitation of the composition and structure of the plastic film, there are the following problems in the actual operation process: the temperature in spring and autumn is suitable for the growth of crops in the greenhouse, and the greenhouse needs to be ventilated. If the temperature is too high, a large area of ​​ventilation is required for the greenhouse. If the temperature is too low in winter, the greenhouse needs to be airtight and insulated to prevent frostbite of the crops. In order to ensure that the temperature in the greenhouse is suitable for the growth of crops, it is currently achieved by manually rolling the plastic film. The greenhouse is ventilated, manually covered with plastic film, and the construction and dismantling of the plastic film greenhouse requires manpower, which is time-consuming and laborious. It is not convenient for the next use, so that every time it is used, the greenhouse skeleton needs to be rebuilt and then covered with plastic film. Due to the large planting area of ​​crops, manual roll film ventilation, high labor intensity and low efficiency
