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
The invention relates to a kind of fertilizer application technique, specifically a kind ofly uses the method for carbon dioxide fertilizer big Tanaka, particularly a kind of method of utilizing irrigation system in the water-saving agriculture land for growing field crops to be used CO 2 gas fertilizer.
Background technology
45% of dry matter is carbon in the plant corpus, and its source is carbon dioxide in air, and whenever synthetic 1g dry matter need consume the 1.6g carbonic acid gas.The optimum gas concentration lwevel scope of plant growing photosynthesis is about 1000ppm, when not being higher than saturated concentration, and photosynthesis rate and the gas concentration lwevel relation of being proportionate.
Though carbon dioxide discharging in recent years continues to increase, concentration of carbon dioxide also only is increased to about 350ppm in the atmosphere, is difficult to reach the optimum gas concentration lwevel of plant growing.
In agriculture developed country, carbon dioxide fertilization extensive use in industrialized agriculture, carbon dioxide fertilization concentration commonly used is at 800～1200ppm, and amount of increase in production is 30%～40%.Because industrialized agriculture is the space of a relative closure, uses to carbonic acid gas and brings operability and controllability, various CO 2 gas fertilizer productions and application process have been tending towards perfect.
And the land for growing field crops agricultural is the space of an opening, how carbonic acid gas is used big Tanaka and is also existed a lot of problems to need to solve, for example how example is discharged carbonic acid gas at regular time and quantity, and how distributing equably, when to discharge and make crop well-tolerated after the dispensing all is the technical issues that need to address.
Therefore, a kind ofly use carbon dioxide fertilizer in the land for growing field crops, with increase the plant canopy gas concentration lwevel, promote photosynthesis of plant, the method that improves the yield and quality, particularly utilize existing irrigation system to carry out the method that carbon dioxide fertilizer uses and just be suggested.
Summary of the invention
The purpose of this invention is to provide a kind of method that carbon dioxide fertilizer increases the plant canopy gas concentration lwevel to reach, promotes photosynthesis of plant, raising crop yield and quality, particularly a kind of method of utilizing existing irrigation system to use carbon dioxide fertilizer used in the land for growing field crops.
Main points of the present invention be utilize irrigation system in the present water-saving agriculture carbon dioxide is used in the land for growing field crops.
Concrete grammar of the present invention is as follows: described irrigation system is drip irrigation or the irrigation system during water-saving agriculture is irrigated, this irrigation system comprises the arm and the hollow billet of pipe-line system at least, the container that carbon dioxide is housed is incorporated at arm place interface, open the valve of container, make carbon dioxide enter hollow billet and discharge and be applied to the plant canopy from the hollow billet delivery port by pipeline, the dispensing time is 2～3 hours/day, and the dispensing amount is 300～400 liters/mu/days.
Above-mentioned using is preferably in the crop growth Sheng phase and carries out, and selects fine the strongest time period of solar radiation, selected time period to be preferably between local time 10～15.
As improvement, above-mentioned dispensing preferably takes segmentation to carry out: in preceding 20～40 minutes of dispensing, every mu dispensing amount is controlled at 4～5 liters/minute, then reduce the speed of discharging thereafter, every mu dispensing amount is controlled at less than 4 liters/minute, be preferably 1～1.5 liter/minute, total dispensing amount is at 320～375 liters/mu/days.
Through evidence, use at drip irrigation cotton, sauce with crops such as tomato, wheats, can improve crop yield 8%～13%, 3～5 days premature ripening phases.
The present invention utilizes irrigation system to make transfer passage and makes source of the gas to land for growing field crops dispensing carbon dioxide, and simple and feasible, dispensing is even, and consumption is controlled easily, and is safe and reliable, low price.
