Problems solved by technology

[0008] However, the use of chemical pesticides has serious drug residues and great harm, which has attracted great attention from relevant departments and consumers; and the use of pesticides requires a large amount of labor and is expensive, which greatly increases the cost of planting and planting, and the benefits are small.

Effect test

Embodiment 1

[0027] Example 1. Experiments were conducted in tomato and pepper vegetable greenhouses, and the insecticidal and sterilizing effects were obvious.

[0028] Open a wind eye on the top of the greenhouse, and charge 98% of the carbon dioxide industrial by-product gas in the hydrogen production device from the bottom of the greenhouse to the greenhouse without oxygen gas. When the air in the greenhouse is exhausted, close the wind eye and keep 5 Days.

[0029] After the environmental transformation, through the use of insect-proof nets and other measures to reduce the entry of pests, pollution-free vegetable products can be produced in this protected area.

Embodiment 2

[0030] Example 2. Experiments were conducted with nitrogen in a vegetable greenhouse, and the insecticidal and sterilizing effects were obvious.

[0031] Open a wind eye at the top of the greenhouse, and fill the greenhouse with 99% nitrogen from the bottom of the greenhouse. When the air in the greenhouse is exhausted, close the wind eye and keep it for 6 days.

Embodiment 3

[0032] Example 3. Carbon dioxide gas was tested in a vegetable greenhouse, and the insecticidal and sterilizing effects were obvious.

[0033] Open a wind eye on the top of the greenhouse, and fill the greenhouse with 96% carbon dioxide gas produced by fermentation from the bottom of the greenhouse. When the air in the greenhouse is exhausted, close the wind eye and keep it for 8 days.

Abstract

The present invention provides a new use of no-pollution gas, CO2, N2 and other no-pollution gases are used as field pesticide and sterilizer. After some area is sealed, the no-pollution gas is filled in to make no-oxygen environment killing pest, pathogenic bacteria, etc. After that, air is made to enter to restore the soil environment for plant to grow. The present invention makes it possible to produce green product, lower plant cost and increase plantation utility.

Description

Technical field [0001] The present invention provides a new use of pollution-free gas and its use method. Background technique [0002] The cultivated area of ​​horticultural agriculture in China was only 139,000 hectares in 1990, and by 1999 it had increased by 11 times to 1.684 million hectares. [0003] Before 1990, China's horticultural agriculture was mainly tunnel-type cultivation greenhouses, but in the following 10 years, the greenhouse area has increased by 15 times, and the plastic greenhouse area has increased by 13 times. By 1999, the two combined have reached the total horticultural agricultural area. 60% of it. [0004] In the 10 years before 1999, the area of ​​the new type solar greenhouse has increased sharply by 45 times. The exterior of this greenhouse is covered with heat-insulating materials and can be cultivated through the winter without heating. Before 1990, most solar greenhouses were used for cultivating vegetables. They were simple greenhouses with very...
