Description
Technical field:
The present invention relates to a kind of novel farmland waterlogging stain control device and application technology thereof, belong to the Agricultural Water-Soil Engineering technical field.
Background technology:
At the relatively more outstanding southern area of hypsography low-lying, agricultural drain, the excess water that the certain designed rainfall produces should be got rid of in final stage gutter, field, reduces the farmland groundwater table again, prevents that crop is steeped.Promptly require final stage gutter, field to have water logging control and fall the stain function, also can be referred to as the double type sub lateral drainage ditch of controlling of waterlogging stain, the final stage that existing agricultural drain engineering legislation is referred to as groundwater table is ditch fixedly.Farmland for dry farming farmland and floods and droughts continuous cropping, crop rotation; Fixedly trench depth is generally between 1.0～1.5m for the final stage of regulation and control groundwater table, and the spacing in gutter has very big difference (clay, heavy loam 20～30m because of the difference of various agricultural land soils self water permeability; Medium loam 30～60m; Light earth, sandy loam 60～100m), slope coefficient also because of the soil property difference between 1～2.Lake region soil is often sticking heavy partially, and therefore, drain ditch in the field is than comparatively dense, and volume of earthwork is big, it is many to occupy cultivated land.On the other hand; The final stage of regulation and control groundwater table fixedly its function of ditch mainly is a dewatering; Can not carry out the SEA LEVEL VARIATION regulation and control according to crop each breeding time of anti-stain degree of depth difference; Even carry out combined water drain with hidden pipe, also deciding buried depth because of hidden pipe only has a kind of water level control mode to be difficult to adapt to the demands of different of each growth phase of crop to the farmland groundwater table with outlet.
Summary of the invention:
The objective of the invention is to:, a kind of novel farmland waterlogging stain control device and application technology thereof that double the controlling of farmland waterlogging stain, especially field waterlogging stain are divided row and groundwater table regulation and control that be used for is provided to the defective that prior art exists.
The present invention realizes above-mentioned purpose through following technical scheme:
A kind of novel farmland waterlogging stain control device; It is made up of main drain, draining trench, french drain, suction water pipe, header, gutter, groundwater table regulation device, collecting well and control valve; It is characterized in that: main drain and draining trench are " T " word in the limit, farmland or " rich " word shape is provided with; The draining trench bottom is provided with french drain, is equipped with header in the french drain, and the agricultural land soil surface is provided with the gutter that communicates with draining trench; The draining trench both sides are provided with the groundwater table regulation device, and the water inlet of groundwater table regulation device bottom communicates with suction water pipe, and the delivery port of groundwater table regulation device bottom is communicated with header through tube connector; Draining trench, french drain and header one end are provided with collecting well, and a side of collecting well is provided with control valve, and the control valve bottom is communicated with the main drain through outlet pipe, is provided with flashboard between draining trench and the collecting well; Described collecting well is provided with well lid, and water pump is installed in the collecting well.
