Abstract
The invention provides a greenhouse irrigation system. Corresponding humidity sensors are arranged below irrigation emitters and used for monitoring soil humidity of each local zone and automatically controlling water inlet valves of the irrigation emitters through sub controllers according to objective humidity, and then it is achieved that soil moisture of crop root zones is always kept in an optimal control threshold value. According to the system, capillary tube bundles are omitted, the problem that faults are caused by blockage of capillary tubes is avoided, the system is more reliable, and meanwhile each local zone can be independently controlled, and the water-saving effect is better. The greenhouse irrigation system can be widely applied to the irrigation process of various greenhouse crops and can also be used for popularizing a water head control irrigation method.
Description
Technical field
The present invention relates to a kind of irrigation system, especially relate to a kind of greenhouse irrigation system.
Background technology
For crop dirt is long, all have optimum soil moisture threshold, and Different Crop can be obviously different at the optimal threshold of different growing, but current irrigation system can not make the soil moisture of crop root zone reach target control threshold value.And, crop in dirt growth process can from root actual absorption to moisture be little, but it is to absorb moisture continuously, therefore needs to supply with continuously moisture, this is only real effective water supply.Soil itself has very strong storage capacity, natural world utilizes the moisture saved in soil to provide effective water supply for plant just, but, because soil has very strong seepage and evaporability, in order to maintain the required effective water supply of plant growth, often need thousands of times of ground to provide savings water for soil.
Traditional irrigation mode is exactly the water storage function that has maximally utilised soil, adopting the mode of broad irrigation is that soil holds sufficient moisture, it is long that the later quite a long time all will lean on the savings water in soil to maintain plant dirt, the savings water overwhelming majority in soil can be fallen by evaporation and seepage simultaneously, and the waste of water resource is extremely serious.Meanwhile, for greenhouse, the evaporation of soil moisture also can cause ambient humidity in Room to increase, thereby causes disease aggravation, is unfavorable for that the dirt of farming is long.At present, the mode of drip irrigation saving water resource effectively, and the development level of domestic and international drip irrigation is also more and more higher, but because the irrigator minimum of drip irrigation goes out water speed all per hour more than 2 liters, be far longer than the actual water speed that needs of plant, water use efficiency is not high, though the waste of water resource is alleviated to some extent compared with other irrigation methods, still has many wastes.In addition, the power-driven system of drip irrigation is comparatively complicated, and dropper easily sends out dirt and stop up, and makes the operating cost of drip irrigation system higher, uses for a long time inadequate economy.
CN201210535166.4 provides the desirable regulation and control of a kind of chamber crop irrigation system, this system supplies water by capillary based on capillary interstice suction and weight-driven principle, has realized the balance regulation that meets irrigator discharge velocity and soil water potential target requirement.But still there are the following problems for this system: (1) adjustability is poor, due to based on capillary interstice suction and weight-driven, in same greenhouse, the soil environment of zones of different is all different, the suction producing is also different, this just makes under identical control, that supplies water is inhomogeneous, some positions lack of water, the waste of some positions; (2) dirt obstruction has been sent out in hollow billet and bundle of capillary tubes, in order to address this problem, in this invention, be provided with filter membrane at the irrigation pipe of irrigator and the junction of tube connector, but this has very high requirement for water supply quality, if water quality is not good, the filter membrane life-span is very short, need frequent replacing, be difficult to guarantee normal use, and do not use filter membrane, hollow billet and bundle of capillary tubes meeting are stopped up fast.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of water-saving result good, can effectively ensure the desirable greenhouse irrigation system of crop root zone soil moisture in optimum control threshold value and reliable in structure.
For achieving the above object, the present invention takes following technical scheme: a kind of greenhouse irrigation system, is characterized in that: it comprises support water-storing device, irrigation pipe network, head elevator and controller; Described water-storing device comprises a water tank that is fixed on described cantilever tip, is provided with the level sensor of a monitoring height of water level in described water tank, and a side of described water tank connects water delivery house steward by a water inlet main valve, and opposite side connects a flexible pipe by an outlet valve; Described irrigation pipe network comprise one with the arm of described soft pipe connection, on described arm, be arranged at intervals with some hollow billets, the common blast pipe that connects of end of each described hollow billet, vertically elevate above the soil in the two ends of described blast pipe; Described in each, on hollow billet, be arranged at intervals with some irrigators, described in each, irrigator comprises a tube connector, the top of tube connector and described hollow billet internal communication described in each, described in each, the inside of tube connector is provided with water intaking valve, described in each, the bottom of tube connector connects an irrigation pipe by internal thread, the end of described irrigation pipe is taper, and is provided with apopore; In the soil of described irrigator below, be provided with humidity sensor; Each hollow billet arranges a sub-controller; Described head elevator comprises the rope that one end is fixing, and described rope is connected with described water tank with water tank stay cord by an assembly pulley; Described controller is electrically connected with described level sensor, water inlet main valve and sub-controller respectively, and described sub-controller connects with water intaking valve and the corresponding humidity sensor of all irrigators that arrange on corresponding hollow billet.
The present invention by arranging corresponding humidity sensor below irrigator, monitor the soil moisture of each regional area, and by sub-controller according to the water intaking valve of the automatic Controlled irrigation device of target humidity, thereby realize make all the time crop root zone soil moisture in optimum control threshold value.This system has been saved the use of bundle of capillary tubes, has avoided capillary to stop up the problem that causes fault, and system is more reliable, can control separately each regional area simultaneously, and water-saving result is better.The present invention both can be widely used in the irrigation process of various chamber crops, also can be for promoting head control irrigation method.
