Abstract

The invention discloses a fertilizer applying technology which specifically applies the carbon dioxide gas fertilizer on the field crops by use of a micro-irrigation system of the current water-waving agriculture. The micro-irrigation system at least comprises a branch pipe and a capillary pipe of a pipeline system; a container filled with the carbon dioxide gas is connected to the joint of the branch pipe, and a valve of the container is opened so that the carbon dioxide gas enters the capillary pipe through the branch pipe and is discharged from a water outlet of the capillary pipe and applied to a plant canopy layer, wherein the daily applying time is 2-3 hours, and the daily applying quantity is 300-400 liters per mu. Tests indicate that the crop yield can be increased by 8-13% by applying the carbon dioxide gas fertilizer on crops such as carbon dioxide gas to the drip irrigation cotton, sauce tomato, wheat and the like, and the mature period is 3-5 days earlier. According to the invention, the micro-irrigation system is used as a conveying channel to apply the carbon dioxide gas to the field, and the carbon dioxide gas is used as a gas source; and the method is simple and feasible, easy to control dosage, safe, reliable and chip, and realizes uniform application.

Description

technical field

[0001] The invention relates to a fertilizer application technology, specifically a method for applying carbon dioxide fertilizer in a field, especially a method for applying a carbon dioxide gas fertilizer to a field by using a micro-irrigation system in water-saving agriculture. Background technique

[0002] 45% of the dry matter in plants is carbon, and its source is carbon dioxide in the air. It takes 1.6g of carbon dioxide to synthesize 1g of dry matter. The most suitable carbon dioxide concentration range for plant growth and photosynthesis is about 1000ppm. When the concentration is not higher than the saturation concentration, the photosynthesis rate is positively correlated with the carbon dioxide concentration.

[0003] Although the emission of carbon dioxide gas continues to increase in recent years, the concentration of carbon dioxide in the atmosphere has only increased to about 350ppm, and it is difficult to reach the optimum concentration of ca...
