Description
Technical field
The utility model relates to the instrument of analyzing with weighing technique, in particular to the instrument that is used to measure the vega soil water evaporation quantity.
Background technology
Be clear and definite crop law of needing the water and then scientific and reasonable guidance irrigation, need study that lysimeter then is the main means of carrying out this type of research to two major parts (evaporation and cigarette strain transpiration between) of crop evapotranspiration.Tobacco is as a kind of important nonirrigated farmland industrial crops, and its planting density is little, and the vega soil evaporation capacity is big, is needing more aspect the cigarette wate research that its ground evaporation between plants is measured research.
At present, having of relevant lysimeter application Chinese patent: CN98244556.3 number " window formula draining lysimeter ", CN02240064.8 number " field crops suspension type weigh electrical measurement lysimeter ", CN03134131.4 number " three compensation lysimeter measurement mechanisms ", CN03236025.8 number " pressing air-breathing drainage type lysimeter ", CN200610104683.0 number " full automatic underground water constant level compensating evaporimeter-lysimeter ", etc., these lysimeters all have good mensuration effect, but structure is more complicated all, particularly price comparison costliness, its application has been subjected to certain limitation.
Summary of the invention
The purpose of this utility model provides the miniature lysimeter of a kind of vega soil, and existing pvc pipe spare costs of manufacture such as drainpipe on the Water and Waste Water Engineering, straight joint, plug are cheap to realize utilizing, the miniature easily lysimeter of operation is measured the vega soil water evaporation quantity.
The miniature lysimeter of the vega soil that the designer provides is made up of urceolus, inner core, back cover sleeve and connecting cylinder; Wherein, urceolus and inner core all are cylindrical tubes, and connecting cylinder is the cylindrical tube that the middle part has bulge loop, and the back cover sleeve is made of two sections different cylindrical tubes of external diameter, and the little hypomere of epimere is big, and the bottom is airtight; Inner core is socketed within the connecting cylinder upper end, is positioned at the bulge loop place of connecting cylinder; Back cover sleeve epimere and the socket of connecting cylinder lower end and by the glue close adhesion in case rainwater exosmose; Space between sealed outer cylinder and the inner core covers with the waterproof ring washer, with avoid rainwater along inner tank theca in connecting cylinder partly flows into the back cover sleeve that is filled with water; A gauze is arranged between inner core and the back cover sleeve, be used for preventing that earth from falling; Urceolus then all entangles inner core, back cover sleeve and connecting cylinder.
The external diameter of above-mentioned inner core and the internal diameter of connecting cylinder are complementary, and promptly the internal diameter of connecting cylinder is slightly larger than the external diameter of inner core; The external diameter of back cover sleeve epimere also is complementary with the internal diameter of connecting cylinder, and promptly the internal diameter of connecting cylinder is a bit larger tham the external diameter of back cover sleeve epimere.
Above-mentioned urceolus, inner core, back cover sleeve and connecting cylinder all adopt pvc pipe to make, and can utilize existing pvc pipe spare such as drainpipe on the Water and Waste Water Engineering, straight joint, plug to make in actual fabrication.
For conveniently inner core being put into urceolus or taking out from urceolus, adopt the high-density polyethylene plastics bag that inner core, coupling sleeve, back cover sleeve three are fitted together after connecting when putting into, pinch inner core (the dress soil about 3kg in back) on the other hand, twisting polybag puts into urceolus on the other hand, as the same during taking-up; Take out the back convenient take by weighing respectively soil in the inner core heavy with the back cover sleeve in percolating water heavy.
The determination step of the miniature lysimeter of vega soil is as follows:
1) respectively choose representational mensuration place on the cigarette ridge with in the cigarette ditch, cut the earth at institute's geodetic point and bury the urceolus of lysimeter underground, the suitable for reading and native face of urceolus flushes; 2) fetch earth with inner core, can lie in the inner core upper end with a wooden unit when fetching earth, evenly beaing wooden unit with iron hammer then enters in the soil inner core, do not destroy soil structures as far as possible, carefully dig out inner core and take out undisturbed soil, prevent that with plastics gauze wrapping inner core bottom grogs from dropping with back, doctor blade undisturbed soil bottom; 3) be inner core weight after the electronic platform scale of 0.1g takes by weighing dress soil with sensibility reciprocal; 4) the inner core lower end after will weighing screws in the connecting cylinder upper end gently, puts into high-density plastic's bag then together, pinches inner core on the other hand, the dress soil about 3kg in back, and proficiency is being twisted polybag and is being put into the urceolus of burying underground in advance; 5) at 8 o'clock in the morning next day inner core and the taking-up of back cover sleeve are weighed, to determine the moisture weight of soil evaporation.
The computing formula of ground evaporation between plants is:
E＝W
1-W
2/πr
2
Wherein: E---ground evaporation between plants (mm)
The inner core of the band sleeve at the beginning of the W1---period and soil heavy (g)
The inner core of the band sleeve of W1---period end and soil heavy (g)
6) soil removal and replacement, consistent for guaranteeing the soil moisture in the miniature lysimeter with the actual water cut of field soil, claimed heavy back to change the undisturbed soil in the miniature lysimeter, by the 2nd) go on foot and carry out the soil removal and replacement operation, and then repeat the 3rd), 4), 5) step, each processing selects 3～5 points to arrange miniature lysimeter, makes that to record the result more representative.
The miniature lysimeter of vega soil of the present utility model can be measured soil evaporativeness as a kind of no disturbance, mini-scope ware movably when using method is suitable comparatively exactly, can satisfy the general requirement of cigarette ground soil moisture research.Therefore it is a kind of simple device of measuring the vega soil evaporation, not only makes simply, cheap, and easy to operate, is applicable to the soil of cultivation tobacco.
