Abstract
The utility model provides an irrigation system for a plastic-covered greenhouse, which comprises a water storage area outside the plastic-covered greenhouse and an irrigation pipeline inside the plastic-covered greenhouse, wherein the irrigation pipeline is connected with the water storage area; and a water supply valve and branch pipelines are arranged on the irrigation pipeline. The irrigation system is characterized in that a filter is arranged at the joint of the irrigation pipeline and the water storage area; a soil humidity sensor is arranged in the plastic-covered greenhouse; and a microcomputer controller is arranged outside the plastic-covered greenhouse and is respectively electrically connected with the soil humidity sensor and the water supply valve. The soil humidity sensor can monitor the humidity of soil in the plastic-covered greenhouse in real time, and an irrigation or non-irrigation command can be sent out by the microcomputer controller, so that the humidity of the soil can reach expected standards according to different plants and different growth periods, and the purposes of water saving and accurate irrigation are achieved; and the irrigation system is flexible and convenient to operate and conducive to saving water resources and improving the yield of greenhouse crops.
Description
Technical field
The utility model belongs to field of agricultural production technologies, relates in particular to a kind of green house irrigation system.
Background technology
Green house is the important component part of agricultural facility, utilize the green house culturing vegetable can promote that it is precocious and enrich its output, prolong the supply phase of vegetables, be to enlarge a kind of effective way that vegetables produce, realize year-round supply, the part that is development " three height " agricultural, revitalizes the rural economy is that China's agricultural is moved towards one of modernized, scientific sign.Especially for the northern area of China frost-free season weak point, winter, day and night the temperature difference was big, though and area, the Yangtze river basin can produce some hardy vegetables winter, but kind dullness, and if meet surazo or autumn in summer heavy rain, diastrous weathers such as unbroken wet weather are then grown seedlings early spring and autumn and winter vegetables production all may be subjected to bigger loss, influence the supply of vegetables.Can utilize protection equipment to carry out vegetables production in winter, spring, autumn and utilize green house to carry out vegetable growing, to obtain diversified victual.The greenhouse is in process of crop growth, root system can absorb water from the soil pore space, China's most greenhouse management level of present stage falls behind, irrigation system adopts timing controlled or manual control mode more, can not supply water according to the water requirement of Different Crop and different puberty and crop root, untimely, uneven, insufficient irrigation or excessive phenomenon such as pour water easily occur watering, can not guarantee the growth conditions that plant is good, the good quality and high output that is unfavorable for chamber crop, water use efficiency and irrigation precision are also low, cause water resource waste easily.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of irrigation simple to operate, accurate, can improve the green house irrigation system of crop yield.
The utility model is that the technical scheme of taking that achieves the above object is:
A kind of green house irrigation system, comprise the water reserve that is arranged on the green house outside, and the irrigation pipeline that is arranged on green house inside, described irrigation pipeline is connected with the water reserve, irrigation pipeline is provided with feed water valve and branch line, it is characterized in that described irrigation pipeline and junction, water reserve are provided with filter, be provided with soil humidity sensor in the described green house, green house is provided with microcomputer controller outward, and described microcomputer controller is electrically connected with soil humidity sensor and feed water valve respectively.
Be interval with water jet on the described branch line.
The beneficial effects of the utility model are: soil humidity sensor can be monitored the humidity of soil in the green house in real time, then the soil moisture parameter information that collects is transferred to microcomputer controller, microcomputer controller sends the instruction of whether pouring water, and stops to pour water when soil moisture maintains our predefined irrigation threshold value.Can also set the threshold value of pouring water according to Different Crop and different pursuit of advanced studies puberty thereof, make soil moisture reach the standard of expection, the purpose that reaches water saving and accurately irrigate, flexible and convenient operation is conducive to the conserve water resource and improves the output of chamber crop.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-water reserve, 2-irrigation pipeline, 3-filter, 4-feed water valve, 5-branch line, 6-soil humidity sensor, 7-microcomputer controller, 8-water jet.
Embodiment
In order further to understand content of the present utility model, characteristics and effect, exemplify embodiment now and be described with reference to the accompanying drawings as follows:
A kind of green house irrigation system, comprise the water reserve 1 that is arranged on the green house outside, and the irrigation pipeline 2 that is arranged on green house inside, irrigation pipeline 2 is connected with water reserve 1, irrigation pipeline 2 is provided with feed water valve 4 and branch line 5, irrigation pipeline 2 is provided with filter 3 with 1 junction, water reserve, be provided with soil humidity sensor 6 in the green house, green house is provided with microcomputer controller 7 outward, microcomputer controller 7 is electrically connected with soil humidity sensor 6 and feed water valve 4 respectively, is interval with water jet 8 on the branch line 5.
The soil moisture of 6 pairs of chamber crop root systems of soil humidity sensor is monitored in real time, obtain the water requirement of crop root, with this as irrigating foundation, by microcomputer controller 7 in good time, pour water in right amount, saving water, manually and aspect the raising crop yield good effect being arranged all, can significantly improve the irrigation accuracy, improve the availability of water, the water quality of 3 pairs of conveyings of filter is filtered, and prevents blocking pipe.
More than embodiment of the present utility model is elaborated, but described content only is preferred embodiments of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
