Description
Technical field
The invention belongs to automatic monitoring technology processed, relates generally to the automatic monitoring equipment to water level height, soil dry, humidity in rice terrace in Rice Cropping growth course.
Background technology
Rice Cropping " shallow " " doing " alternate cycles irrigation technique that " wets " is water conservancy department of Heilongjiang Province, the brand-new Rice irrigation technology that applied to the whole province in September, 2010 at Rice in Hei Longjiang Province irrigation tests center, it is subject to the impact of hereditary capacity and growth hormone based on Rice Physiological biochemical action, initiatively apply himself regulative mechanism and adaptive faculty of water stress performance to a certain degree in its some of growing in stage, cause assimilation quotient redistributing between Different Organs, reduce the Growth Redundancy of nutrition organs, improve rice quality, play water saving, high-quality, effect efficiently.This irrigation technique is to adopt " shallow " (the high 30mm of rice field inner aqueous layer), " wetting " (the high 0mm of rice field inner aqueous layer), " doing " (soil moisture water cut control limit value under water), cycle alternation irrigation method.At present, this cycle alternation irrigation method also completes with manual monitoring, labor capacity is large, timeliness is poor, operation quality is low, affect yield of brown rice and quality, water resource and fertile drug effect utilization factor low be must solve ground technical matters.
Summary of the invention
The object of the invention is exactly the problem existing for above-mentioned prior art, shallow for Rice Cropping, wet, dry alternate cycles is irrigated the actual needs of agronomic technique production operation, research and development provide a kind of rice terrace shallow, wet, solid carbon dioxide amount Monitoring and Controlling instrument, solve in advanced agronomic technique popularization and be manually difficult to control, the difficult problem that Technique Popularizing is restricted, reach " shallow " " wet " " doing " control timeliness good, automatically controlling essence quantizes, give full play to " shallow " " doing " alternate cycles irrigation technique good effectiveness in Rice Cropping that " wets ", realize and increase yield of brown rice, improve rice matter, saving water resource, improve fertilizer efficiency drug effect, improve resistance against diseases resistant to lodging, save the object of labour and Rice Cropping irrigation automation.
The object of the invention is achieved in that and on the outside, lower end of housing, is fixedly mounted with successively the anodal detector probe of soil moisture content, negative pole detector probe and pyramid, in housing, can move up and down the anodal detector probe of water level and the anodal detector probe of upper water level under the installation of adjusting, described housing following side inner chamber and outside are connectivity structure, the anodal detector probe of described soil moisture content, the anodal detector probe of lower water level, the anodal detector probe of negative pole detector probe and upper water level is communicated with sensor information processor respectively by wire, described heat transfer agent processor opens and closes self-actuated controller with electronic valve successively by wire and electronic auto-control water valve is connected, so far form rice terrace shallow, wet, solid carbon dioxide amount Monitoring and Controlling instrument.
The beneficial effect of the invention is: realized Rice Cropping shallow, wet, the smart quantified controlling that dry alternate cycles is irrigated, automatically detect water level depth in rice field, soil moisture, automatically control the unlatching of irrigating valve according to the numerical value of setting, close, accurately, automatically automatically irrigate, alleviate manually-operated labour intensity, avoid man-made irrigation range estimation water level depth, the error of soil moisture, make irrigation water science more, rationally, improve seedling growth environment, improve yield of brown rice, improve rice quality, improve rice shoot resistance against diseases resistant to lodging, saving water resource, save labour, improve fertilizer efficiency drug effect, reduce greenhouse gas emission, improve the ecological environment, this Monitoring and Controlling instrument structural design is new reasonable, automaticity is high, measure monitoring precision high, use reliable, fault is few.

Embodiment
Below in conjunction with accompanying drawing, the invention embodiment is described in detail.Rice terrace is shallow, wet, solid carbon dioxide amount Monitoring and Controlling instrument, on the outside, lower end of housing 5, be fixedly mounted with successively the anodal detector probe 1 of soil moisture content, negative pole detector probe 3 and pyramid 9, in housing 5, can move up and down the anodal detector probe 2 of water level and the anodal detector probe 4 of upper water level under the installation of adjusting, described housing 5 following side inner chambers and outside are connectivity structure, the anodal detector probe 1 of described soil moisture content, the anodal detector probe 2 of lower water level, the anodal detector probe 4 of negative pole detector probe 3 and upper water level is communicated with sensor information processor 6 respectively by wire, described heat transfer agent processor 6 opens and closes self-actuated controller 7 with electronic valve successively by wire and electronic auto-control water valve 8 is connected.
When operation is used, utilize pyramid 9 to be inserted in water paddy soil, this controller is fixed on rice terrace, now the anodal detector probe 1 of soil moisture content and negative pole detector probe 3 are also inserted in soil simultaneously, in rice terrace moisture enter in housing 5 with under, the anodal detector probe 2 of upper water level, 4 contacts, 1., in the time that in rice terrace, height of water level drops to 0mm, between the anodal detector probe 2 of lower water level and negative pole detector probe 3, form and open circuit, probe sends signal, arrive heat transfer agent processor 6 through wire transmission, heat transfer agent processor 6 sends water supply instruction, open and close self-actuated controller 7 information processings through electronic valve, send and open valve instruction, electronic auto-control water valve 8 is received instruction by valve open, by water channel to rice terrace irrigation water supply, 2., in the time that rice terrace irrigation level rises to specified altitude, the anodal detector probe 4 of upper water level touches after the water surface, and form loop between negative pole detector probe 3, probe sends signal, and through wire transmission, to heat transfer agent processor 6, heat transfer agent processor 6 sends and stops the instruction of supplying water, open and close self-actuated controller 7 information processings through electronic valve, send valve-off instruction, electronic auto-control water valve 8 is received instruction by valve closing, and water channel stops to rice terrace irrigation water supply, 3., when water paddy soil surface no water layer, and while there is crackle in soil, between the anodal detector probe 1 of soil moisture content and negative pole detector probe 3, form and open circuit, probe sends signal, and through wire transmission, to heat transfer agent processor 6, heat transfer agent processor 6 sends water supply instruction, open and close self-actuated controller 7 information processings through electronic valve, send and open valve instruction, electronic auto-control water valve 8 is received instruction by valve open, by water channel to rice terrace irrigation water supply.
The invention can be carried out automatic irrigation control according to the definite cyclic irrigation mode of paddy rice different growing stages.
This controller makes shallow, wet, the dry alternate cycles of advanced Rice Cropping irrigate agronomic technique to apply and be achieved, its technique effect is outstanding and remarkable: realize every mu of year water saving 35% of Rice Cropping, mu volume increase 10%, saving sees that water operation labour is more than 80%, production cost declines to a great extent, for paddy rice in cold region large area volume increase in Heilongjiang Province's provides technical support.
