Abstract
A kind of method for changing sandy dry land into paddy, by method at the thick polyethylene film of the obturator-type polyethylene foam sheet material of the sandy nonirrigated farmland embedding thickness 5～8mm in 50cm depths and 0.10～0.15mm, make sandy nonirrigated farmland can become the fabulous paddy field of moisture capacity, use the present invention can increase substantially the output and the output value in soil.
Description
One, technical field:
The present invention relates to modify-water field, nonirrigated farmland technology, particularly a kind of modify-water field, sandy nonirrigated farmland technology that obturator-type polyethylene foam sheet material is combined with thick plastic film.
Two, background technology
As everyone knows, after the nonirrigated farmland changes the paddy field into, crop yield per unit area can be increased substantially, the accommodation of farmland can be expanded again crop species.But modify-water field, nonirrigated farmland not only is subjected to the restriction at water source, more is the large-area sand of the restriction that is subjected to soil property, particularly northern China, because water retention capacity is poor, then can't implement this improvement project.
Three, summary of the invention
The purpose of this invention is to provide a kind of method for changing sandy dry land into paddy, to adapt to the needs in modify-water field, sandy nonirrigated farmland.
The object of the present invention is achieved like this: adopting thickness is the water conservation layer that the obturator-type polyethylene foam sheet material of 5～8mm and polyethylene film that thickness is 0.10～0.15mm wait to change the field, according to the fabric width of foam sheet and polyethylene film fabric width substep nonirrigated farmland earth is risen to the degree of depth of 50cm by at least 2.5 times, spread film behind the foam sheet of shop earlier, require sheet material and film can cover the height of ridge 2/3 on every side simultaneously, junction at two width of cloth sheet materials and two width of cloth films, use neutral weather resistant neutral silicone glass cement bonding respectively, backfill earth after 24 hours, fill out work up to the shop of finishing en bloc, at last ridge is earthed up, be densified to the plan height.
Adopt such scheme can receive following remarkable result:
1, irrigating by lifting water to a higher level with a water pump, etc. under the very universal situation of equipment, the major obstacle in modify-water field, nonirrigated farmland is in soil property, because the poor water retention property of sand, so can only plant dry crop, after adopting this programme, can change a large amount of sandy soils into paddy field, this will increase substantially the output of crop and the output value in soil.
2, adopting the method for the rebasing water conservation of plastic film is a kind of known method, but because film is unable to undergo to trample, particularly be unable to undergo the extruding of sand grains, stone, so single in the engineering in modify-water field, nonirrigated farmland is the water retention that does not have expection with it, yet with it with after foam sheet combines, then both kept good impermeable role, and given anti-trampling and the anti-film ability of sand grains, stone mutual extrusion up and down again, thereby received highly desirable water conservation effect.
3, the tilth in paddy field is 25～35cm, and this programme is arranged on the 50cm depths with the water conservation layer, so can be not impaired because of farming.
4, make the adhesive of this programme with the weather resistant neutral silicone glass cement, both be convenient to construction, effect is good again.
5, be in the vinyon foam sheet of embedding state and life-span that film is kept its normal function more than 20 years, so the ratio for input and output value of this programme is very high.
