Method for storing mint through nitrogen charge of greenhouse draught fan

Abstract

The invention discloses a method for storing mint through nitrogen charge of a greenhouse draught fan. A greenhouse frame is erected in a mint raw material gathering place, the cross section of the greenhouse frame is of a structure similar to an ellipse, the greenhouse frame is 10 meters long and 4 meters wide, and the distance between the highest point of the greenhouse frame and the ground is 2 meters. After the greenhouse frame is erected, the greenhouse frame is covered with a plastic film, and people need to pay attention to that the plastic film completely covers the greenhouse frame. After the greenhouse frame is completely covered, the redundant part of the plastic film stretches out of the greenhouse frame and is pressed through soft pads and evenly pressed on the ground, the soft pads are pressed by wood plates, and the soft pads are connected with the ground through bolts to guarantee the sealing characteristic of a greenhouse. The draught fan is placed on one side of the greenhouse and connected with an air inlet valve, and air is supplied into the greenhouse through the air inlet valve. An air outlet valve is connected to the other side of the greenhouse. A humidity monitor and a temperature monitor are arranged in the greenhouse and used for monitoring the humidity and temperature conditions in the greenhouse in real time.

Description

technical field [0001] The invention relates to greenhouse storage and agricultural fresh-keeping technology, in particular to a method for storing mint by filling nitrogen into a fan in a greenhouse. Background technique [0002] The whole world is looking forward to pollution-free food and a green environment. To realize these expectations, ecological agriculture should be developed. This requires the world's agriculture to transition from chemical agriculture to physical agriculture. Physical agriculture can promote the process of ecological agriculture and enable The development of human society has become sustainable development. After several years of experiments and investigations, it was found that the following physical technologies are very successful in the application of vegetable greenhouses. [0003] In the vegetable greenhouse, the light is weak and the intensity is low in winter, which is not good for the growth of vegetables in the greenhouse. Hanging a refl...
