Description

A kind of fertigation aerating agitating device and method
Technical field
The present invention relates to irrigating the Integration of Water into Fertilizer field, specifically, disclose a kind of fertigation aerating stirring Device and method.
Background technology
Irrigating the Integration of Water into Fertilizer is will to irrigate the new agricultural technology combining together with fertilising.Water-fertilizer integral is made by Pressure system (or landform natural-drop), by soluble solids or liquid fertilizer, by the need of soil nutrient content and crop species Fertile rule and feature, the solution dissolving together with irrigation water, by controlled pipeline system water supply, fertilizer, after so that liquid manure phase is melted, Drip irrigation, uniformly, regularly, quantitatively, infiltration crop root development growth region are formed by pipeline and water dropper, makes main root soil Remain loose and suitable water content, simultaneously the nutrient uptake feature according to different crops, soil environment and nutrient content shape Condition;Crop different growing stages need water, and regulation of fertilizer requirement situation carries out the Demand Design of different growing, fixed to moisture, nutrient timing Amount, is supplied directly to crop in proportion.
Irrigate the advantage that the Integration of Water into Fertilizer has " three sections, a province, four carry "." three sections " can achieve that water saving, section are fertile With section medicine.This technology quantitatively can be supplied water to root of the crop layer in time from pipeline, can need to carry out quantitation to local according to crop Irrigate and fertilising, greatly improve the utilization ratio of water, realize agricultural water resources and significantly save." province " refers to saving of labor, due to adopting Realize automatic fertilization with irrigation equipment to water, working feature and the labor intensity of conventional irrigation fertilization can be reduced in a large number." four Carry " refer to that this technology can improve water resource utilization efficiency, improve fertilizer utilization efficiency, simultaneously because the in good time fair supply of liquid manure, Crop yield can be dramatically increased, improve the output efficiency in unit arable land, therefore also improve Cultivated Land Use efficiency.Additionally, This technology can realize the raising of fertilizer utilization efficiency, therefore can mitigate or even avoid agricultural fertilizer to soil, water body face source The risk of pollution, simultaneously as the reasonable employment of liquid manure can reduce the generation of pest and disease damage, reduces Pesticide use, improves agricultural production Product production safety level and Agro-ecology level, mitigate pesticide residues environmental pollution and the harm to human body.
At present, irrigate the Integration of Water into Fertilizer to have begun to promote the use of in slight irrigation, and exist in terms of the irrigation of land for growing field crops Dose is big, and liquid fertilizer is few, and the factors such as price height, the liquid manure one of the water-fertilizer integral in land for growing field crops, particularly sprinkling irrigation Change and be difficult to promote the use of.Currently, solid fertilizer in water-fertilizer integral, is dissolved by water mostly, because its dissolution velocity is slow, a lot Device is stirred accelerating dissolving using adding the modes such as agitator, to help more efficient molten fertile, fertilising.
