Abstract

The invention discloses a soil waterlogging removing method. Waterlogging is lowered mainly in the mode that deep ditches are dug in regions prone to water accumulation of hill land, and water seepage pipelines are buried. The water seepage pipelines are formed by combining pored PVC pipes with bamboo poles. By means of the soil waterlogging removing method, the problem of soil water accumulation is solved, and meanwhile the defects that land drainage ditches are not beneficial to production operation, and a large amount of labor is used for ditch cleaning are overcome.

Description

The method for removing of soil waterlogging

Technical field

The present invention relates to a kind of farmland that is applicable to hilly country and fall stain method, be specifically related to a kind of method for removing of soil waterlogging.

Background technology

In knob, due to the out-of-flatness in soil, there are a lot of easily places of ponding, when Planting Crops, can form water stain evil.Traditional method for removing is, drainage trenching carries out draining and falls stain, time has been grown ditch body and easily caves in, stops up, need often cleaning, and ditching on soil, is also unfavorable for production operation, the space of especially walking for automated agricultural machine tool on hilly ground had very limited originally, after excavation open channel, had more restricted do mechanization operation.How to design a kind of new stain method of falling, can be when solving soil ponding problem, overcome the drawbacks such as land drain is unfavorable for production operation and ditch cleaning recruitment is many, become technical problem urgently to be resolved hurrily.

Through retrieval, Chinese patent CN102172202A provides a kind of water paddy irrigation draining automaton, utilize the devices such as water level switch board, ball float and water pump to control draining, realized steeping harmful active prevention, but this covering device cannot directly be used in hilly country, and has used automatic control, and cost is higher, it is installed, use and maintenance is also higher to operating personnel's requirement, is unsuitable in rural area or private plantation spread.

Summary of the invention

Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of can be in hilly country effective draining do not affect the method for removing of the soil waterlogging of do mechanization operation.

Technical scheme: for solving the problems of the technologies described above, the method for removing of soil waterlogging provided by the invention, comprises the following steps:

1) choose the region that hilly ground has ponding, according to landform, to the direction that is beneficial to ponding discharge, excavate zanjon;

2) at bottom of trench, lay water permeating pipeline;

3) return soil and fill out ditch, return soil height and become natural grade with plantation soil.

As preferably, the ditching depth in described step 1) is 80 ~ 100cm, and the inclination angle of described bottom of trench is consistent with the slope aspect of landform.

As preferably, described step 2) water permeating pipeline in is the pvc pipe of perisporium perforate, and the perforate outside of described pvc pipe is coated with bamboo pole, and the diameter of described bamboo pole is slightly less than the aperture of perforate.

As preferably, described step 2) water permeating pipeline in is boundling bamboo pole, and described boundling bamboo pole comprises that 8 ~ 20 diameters that close up arrangement are 1 ~ 3cm bamboo pole.

Beneficial effect: the method for removing of soil waterlogging of the present invention, utilize and to ooze principle under water, use covered conduit pipe drainage, compare surface, existing soil and dig trenches to drain the water away and fall stain mode, there is following advantage:

1, can reduce drain cleaner recruitment, once drop into and can use for many years;

2, avoid surface, soil trench digging, be unfavorable for the shortcoming of production operation, be convenient to plantation planning;

While 3, utilizing boundling bamboo pole as water permeating pipeline, its fiber and pore have played good regulating action to the balance of moisture, and after underground rot to flora in can balance soil, and supply nutrients for the growth of earth's surface crop.

Embodiment

Embodiment: choose the hilly ground that stain evil often occurs at a place in tea plantation, the Maoshan Mountain, Jurong City, according to following steps, technical scheme of the present invention is verified:

1, the place that has ponding in soil, excavates zanjon (ditching depth suitably regulates according to varieties of plant) according to landform to the direction that is beneficial to ponding discharge;

2, pvc pipe road with holes, permeable, bottom of trench discharge surface;

3, after row of conduits is put well, lay one deck small bamboo above pipeline, bamboo pole is covered in the perforate outside of pvc pipe, and the diameter of bamboo pole is slightly less than the aperture of perforate.Utilize bamboo pole to split hole and form certain blocking, organize earth to stop up perforate, and rotten rear its fiber of bamboo pole has further played filtration to perforate, moisture can only slowly permeate by bamboo fibre, can there is not excessive draining, the water balance that has kept crop root, the water requirement of especially applicable tea tree, supplies water in optimum state its root.

4, return soil and fill out ditch, return soil height and become natural grade with plantation soil;

First the humidity on Timing measurement earth's surface, states in the use the rear humidity of method processing and has occurred obvious decline.

, there is obvious decline near measurement subterranean water level near pipeline 1 ~ 2m two days later, and a little less than the height of pipeline.

In rainfall one day after, measure subterranean water level, find that subterranean water level is the height a little more than pipeline.

The tea tree contrast of growing in the experimental field that the present invention was processed and near same physical features, its growing way, output all improve significantly.

Claims

1. a method for removing for soil waterlogging, is characterized in that comprising the following steps:

2) at bottom of trench, lay water permeating pipeline;
