Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment 1:
Ground moistening forward detection instrument shown in Figure 1, the inside of vertical hollow bushing 1 is provided with a foam buoy 2, bottom ring set one funnel 3 of this hollow bushing 1, these funnel 3 ring sets are on the outer tube wall of hollow bushing 1 bottom, and they are fastenedly connected by set collar 7.
Described funnel 3 bottoms exceed hollow bushing 1 lower end, this inboard that exceeds the funnel 3 of part arranges a circle granular membrane 4, and the lower end of funnel 3 connects one section water pipe 5, and the bottom of this water pipe 5 is provided with a suction tube 6, and described suction tube extends upward ground from the bottom of water pipe 5.The water pipe 5 of described funnel 3 bottoms can be stored the soil liquid, utilizes suction tube 6 tubules of its bottom connection with soil liquid sucking-off, for monitoring nitrate nitrogen, conductivity, pH value etc., whether has Nutrient Leaching and salt accumulation problem thereby understand.
The length of described buoy 2 is the distance of hollow bushing 1 top to funnel 3 lower ends.Moisture in the soil enters water pipe 5 through funnel 3, filtrator 4, after the water in the water pipe 5 reaches certain depth, produces buoyancy, with buoy 2 jack-up.The user can understand the position that moistening peak arrives by the lifting of buoy 2.
Use procedure:
Ground moistening forward detection instrument is imbedded crop root zone, when irrigating, moisture is mobile in soil, and when moistening peak arrived the funnel edge, a part of water flowed into the funnel bottom with hopper walls, fully after the water inlet, soil is in the water saturation state herein, and the filtrator of free moisture by the funnel bottom enters the water pipe of bottom, after water reaches certain depth in the water pipe, produce buoyancy, with buoy jack-up.The user can understand the position that moistening peak arrives by the lifting of ground exposed portions serve buoy, stops to irrigate or the decision that continues to irrigate thereby make.When the buoy that bassets slowly descends, show that the holard reduces, or the reach of moistening peak, drop to a certain degree and can again irrigate.
Ground moistening forward detector wants two to use simultaneously usually.A shallow embedding, one buried.To drip irrigation, detector to be embedded in water dropper under.Generally shallow one is embedded in about 30cm, and dark one is embedded in about 60cm.The concrete degree of depth is because deciding according to root layer distributed depth.For sprinkling irrigation and microspray irrigation, detector will bury more shallowly.Generally bury two degree of depth of 20cm and 40cm.
As shown in Figure 2, if the shallow-layer detector irrigation season buoy seldom float and show that water does not arrive most of root system district, should water more water.
As shown in Figure 3, the shallow-layer buoy floats when major part is irrigated, and the deep layer buoy stops when floating irrigating, and this moment, the moisture of soil was suitable.
As shown in Figure 4, if shallow and dark two buoys all float and the length of holding time, show that irrigation is excessive.Reduce irrigation volume or prolong and irrigate the interval.
Moistening forward's detection instrument can be used for formulating irrigation project.It is relevant with the initial water content of soil that moisture arrives time of a certain degree of depth.If soil is dry before irrigating, because moisture is wanted the filling soil hole in moving process, moistening peak moves very slow, and detector is responded needs the long period (time of namely irrigating is long); If high humidity before the soil irrigation, then the speed that moves of moistening peak is fast, because the soil aperture is by water saturation.This moment, detection instrument detected the time at moistening peak with regard to weak point.
