Abstract

The invention discloses a method for increasing the yield and quality of greenhouse vegetables. Nitric Oxide gas is fertilized in a greenhouse once a day from three to four weeks before the harvest time of the greenhouse vegetables till the day before the harvest time according to routine estimation, the amount of fertilizer applied each time is 0.5 to 2 mL/m<3>. The invention also provides an acquisition device of NOx gas for realizing the method, which comprises a gas collection bag which is provided with an inlet and a gas extracting port. A reaction vessel is arranged on a heating device, one end of a connecting tube is connected with the outlet of the reaction vessel in a sealing way and the other end is connected with the inlet of the gas collection bag in a sealing way, and the connecting tube is provided with a regulator. The method of the invention can not only reduce the nitrate content in the vegetables but also increase the yield of the vegetables.

Description

technical field [0001] The invention relates to a method for improving the output and quality of vegetables in greenhouses by applying a small amount of nitric oxide gas externally and the device used. Background technique [0002] In addition to providing various nutrients such as proteins, carbohydrates and minerals needed by the human body, vegetables also contain a variety of natural antioxidant substances, such as ascorbic acid and total flavonoids, which are highly regarded by the world's nutrition and medical circles. Beneficial substances of concern to the world. With the development of the economy and the improvement of living standards, the public's awareness of the demand for green vegetables has begun to increase. Therefore, a high-quality and high-yield vegetable production model is very urgent. At present, vegetable greenhouse production has been widely carried out all over the world; especially in China, in the past few decades, vegetable greenhouse producti...
