Abstract
The invention discloses a plastic film mulching method comprising the following steps: (1) soil preparation: leveling a plot to be mulched with a plastic film; (2) film unfolding: unfolding the plastic film to be mulched on the surface of the plot flat; (3) edge soil covering: covering soil on two edges of the plastic film; and (4) covering soil rolling: rolling the covering soil at the two edges of the plastic film to be compact. The width of the plastic film mulched by using the method is horizontally exposed to the sun, and the plastic film thoroughly plays the roles of raising the temperature and holding water and promotes the effect by about 31% as compared with the prior art; and proved by field tests, the plastic film mulching method ensures that the yield is increased by 91.5kg/mu under the condition that seeds, fertilizer, water and number of plants in unit area are same. The plastic film mulching method provided by the invention has the advantages of no need of ditching, low labor intensity, labor saving, high efficiency, environment pollution reduction and environment friendliness, and facilitates the recovery and clearing of the plastic film in the field. If the plastic film mulching method can be popularized and generalized on a large scale across the country, huge yield-increasing and energy-saving effects can be achieved.
Description
Technical field
The invention belongs to the agriculture cultivation technology field, relate to a kind of laying method of mulch film, particularly relate to a kind of tiling method of mulch film.
Background technology
Plastic mulching is a kind of effective agricultural cultivation yield-increasing technology, and there is more than 200,000,000 mu of plastic mulching plantation farmland every year in China at present, and the trend of cumulative year after year is arranged.
During plastic mulching, the film limit of mulch film must be fixing with soil.Existing mulch film bedding method is, earlier with machinery with the soil trench digging, spread film then, be pressed in the ditch with mechanical both sides again mulch film, fixedly mulch film at last bankets in ditch.After so operation finished, the film in must placing into the soil in the mulch film both sides was wide about about 25 centimetres.Therefore, there is following open defect in existing mulch film laying method: the wide about 25 centimetres of left and right sides mulch films during place into the soil (1) can not play the effect that promotes soil temperature, therefore belong to a kind of wasting of resources, have strengthened the input of the means of agricultural production; (2) the solid embrane method work of the trench digging of prior art intensity is big, and effect is low; (3) mulch film that is pressed in the soil of trench digging is difficult to before and after the autumn harvest remove, and very easily contaminated soil is runed counter to environmental protection.
Summary of the invention
The objective of the invention is the problem that exists at prior art, the mulch film tiling method of a kind of volume increase, energy-conservation, efficient, environmental protection is provided.
Mulch film tiling method of the present invention comprises the steps:
1) wholely: the plot that will treat plastic mulching is smooth good;
2) exhibition film: will treat that spreading is open and flat on ground surface;
3) edge earthing: earthing on the two edges of mulch film;
4) roll extrusion earthing: the earthing roll extrusion on the mulch film two edges is solid.
When described ground film edge earthing, the earthing width of ground film edge is 8cm～10cm, thickness of earth covering 3cm～4cm.
Described mulch film is the agricultural mulching of width 30cm～180cm, the polyethylene film of preferable width 55cm～140cm.
The edge that described roll extrusion earthing should be guaranteed covering with plastic film is firm, stuffy.
Effective effect of the present invention is: after (1) completes mulch film with mulch film tiling method of the present invention, the whole levels of mulch film width on the sunny side, 100% play the temperature raising water retention, and behind the film of existing plastic mulching method shop, the mulch film commonly used that with the width is 80cm is an example, the mulch film that the energy level faces south is about about 69%, the present invention than prior art at effect promoting aspect the temperature raising water conservation about 31%, through 2 years field trials relatively, at seed, fertile, water, under the identical situation of number of plants per unit area, because of mulch film tiling method temperature raising water retaining function of the present invention obviously is better than prior art, 91.5 kilograms of average every mu of volume increase; (2) the present invention compared with prior art faces south area when identical in the mulch film level that is capped, and can save mulch film width 25cm, is example with Wutai County, Shanxi Province in 2010 80cm mulch film price, and 35 yuan of every mu of mulch film expenses can be saved 10.94 yuan for every mu; (3) the solid membrane process of mulch film tiling method of the present invention does not need trench digging, and work intensity is little, reaches saving of labor's purpose efficiently; (4) mulch film tiling method of the present invention is not because buried in soil with the ground film edge, and the easy mulch film that reclaims and clear up the field has reduced environmental pollution before and after the autumn harvest, helps environmental protection.
In Dong Ru village, Ru Cun township, Wutai County, Shanxi Province, 2008 and 2009 continuous 2 years are used solid embrane method of trench digging and mulch film tiling method of the present invention and are tested with 10 mu of big Tanakas of piece.Two kinds of methods are respectively taken up an area of 5 mu, the kind of dispensing base fertilizer is identical with quantity, with identical corn variety, the same polyethylene film that uses wide 80cm, thick 0.005mm, the back number of plants per unit area of emerging is identical, harvest date is identical, and the results back is surveyed comprehensively and produced, and mulch film tiling method of the present invention as a result is than 89.4 kilograms of every mu of volume increase of solid embrane method 2008 annuals of trench digging, 93.6 kilograms of every mu of volume increase of 2009 annuals, 91.5 kilograms of every mu of volume increase of two annuals.
Embodiment
The land readjustment of preparing sowing, plastic mulching is good, get the field of sowing ready, the agricultural mulching of 30cm～180cm is being contained on the mulch film tiling method special-purpose machinery, passing through mechanical work, mulch film is deployed on the ground surface, and on the two edges of mulch film earthing, every limit earthing width 8cm～10cm, thickness of earth covering 3cm～4cm, finish sowing simultaneously, last rolled film limit earthing makes it solid, guarantees that the edge of covering with plastic film is firm, and is stuffy.
After laying was finished, every interval 45cm～55cm re-layed another mulch film, repeated successively.
