Description

Automatic farmland irrigation system and irrigation method
Technical field
The invention belongs to agriculture fields, and in particular to a kind of Automatic farmland irrigation system and irrigation method.
Background technique
China is all large agricultural country since ancient times, and past irrigation method is all very single, is essentially all manually to fill It irrigates, that has arrived that premodern agriculture facility just develops gets up.But effect is not too much obvious, the crops that can be provided people with convenience Irrigation method only has so several.Such as irrigate, trickle irrigation, flooding irrigation, trickle irrigation etc., but water use efficiency is not high, such as dropper, water conservancy It is only 40% with rate.Low water use efficiency is the maximum problem of all irrigation methods, makes water using some technologies although also having The utilization rate of resource increases, but does not solve the problems, such as from the root.For example use water range much during underground drip irrigation, How much is water consumption, and how many etc. with water duration, these problems are artificially very rambunctious.
Water-saving irrigation is all the basic conception of China's field irrigation since ancient times, but nowadays China's most places agriculture The irrigation method in field also rests on traditional Irrigation, and traditional Irrigation the degree of automation is lower, is essentially all Manual work, not only low efficiency, but also Controlled irrigation amount, waste water resource pole cannot be caused to manpower and material resources well The earth wastes.The concept for developing Automatic farmland irrigation system is an important water conservation, control and effective use water resource It is the core of the system.In order to increase irrigation efficiency, reducing labour cost and save water resource, develops automatic irrigation technology and have become For inevitable trend.Develop the important means that Automatic farmland irrigation system concept is the control and effective use to water resource, it Field irrigation accuracy and validity can be improved, be conducive to the scientific and effective management to irrigation operation process, peasant can root Judged whether suitably to irrigate according to itself experience for many years, the amount of labour can not only be reduced well, and more important Be can accurately, timing, it is quantitative, effectively to crops be timely automatically replenished water, crops can be improved Yield and quality and can it is water-saving, energy saving, reduce labour cost.
Although China there now have been oneself a set of automatic irrigation system, but be in primary development rank Section, the various aspects of system are also less perfect, and most irrigation systems is in the manual operation stage, even if individually The some automatic irrigating control systems of Fang Caiyong, still, it is only from external import or small-scale local control system.China is certainly The autonomous irrigation control system of main research and development is also mature far away, lacks key technology.Discovery local condition in Taixing City of Jiangsu Province is non- The often Remote Automatic Control System of suitable water-saving irrigation, and start to apply for the first time, effect is very good.Chinese automatic control System is for developed country or there is very big gap, and backward in technique and application is not extensive.
Generally speaking, the Technique Popularizing of domestic Related product and experiment are in lower level, and most of product is also Being will be by introducing external first-class product.But introducing automatic control equipment from foreign countries is all according to the specific of oneself country Situation and design, there is no consider China weather and edaphic condition.And crop type and the other countries in China Nor all identical, cannot effectively play its advantage.Since the cost of equipment for introducing complete set is expensive, so It is badly in need of developing price material benefit now and meets the automatic irrigating control system of China's situation.
Summary of the invention
It is an object of that present invention to provide a kind of Automatic farmland irrigation system, including water source, water pump, current-carrying gate valve, fertilizer applicator, Filter, solenoid valve, pressure regulator, spray head, controller, sensor and PC machine;
