Abstract
The invention discloses a method for preventing and removing weeds and reducing evaporation in farmland. Soil is leveled and sowed according to the conventional method; a black mulching film is covered on the sowed soil; the black mulching film contains 2-3% of carbon black, the light transmittance is 1-3%, and the thickness is 0.008-0.01 mm; fine soil with the thickness of 1-2 cm covers the mulching film; and the adopted mulching film is easily degradable and does not contaminate soil. The invention obtains the beneficial effect that: after sprouting, weed seeds are restricted below the black mulching film, can not be irradiated by sun and finally dies so as to obtain the purpose of weeding. Because no damage exists except seed gaps when the whole farmland is covered by a soil-below film, the effect of water retention and water saving can be obtained, and the phenomenon of uncovering the film by strong wind can not happen; and meanwhile, moister below the film can not be evaporated because of the water repellent function of the soil-below film, and the root of the crop has sufficient moisture for growing, thereby obtaining the effect of water saving and synergism. The invention realizes eliminating the damage on the crops caused by the weeds while reducing soil moisture evaporation.
Description
Technical field
The present invention relates to a kind of method of preventing and removing weeds and reducing evaporation in farmland, be particularly suitable for the production of economic crops or top grade flower, belong to agricultural technology field.
Background technology
Weeds are the factors that influence crop yield and quality.In agricultural production, weeds and crops are accompanied, and farmland weeding is a numerous and diverse job.The growth of weeds has not only consumed a large amount of soil nutrients and moisture, with crops contention sunlight, has reduced the photosynthesis of crops simultaneously, causes crop yield and quality to descend.Artificial weeding, weeding by machine have not only strengthened production cost, then are difficult to finish when the dense planting crop production; And using of weed killer herbicide can damage soil physical and chemical property, causes environmental pollution.And because weed killer herbicide causes many crops not use to the selection of weeds kind, simultaneously, weed killer herbicide may damage adjacent crop.It is particularly outstanding that the problems referred to above seem in the production process of some economic crops or top grade flower.Therefore, seek and a kind ofly can suppress weed growth, can reduce the method for soil water evaporation again, significant for the production of optimizing economic crops, top grade flower.
Summary of the invention
The object of the present invention is to provide a kind of method of preventing and removing weeds and reducing evaporation in farmland, realized when reducing soil water evaporation, having eliminated the harm of annual weed crop.
Design of the present invention is: crop seedling individuality is much larger than weed seed, and after crop germinateed, the bud scale penetration power was better than weeds.Cover black mulch film on soil after planting, earthing on the mulch film makes under the film weed seed germination bud scale run into mulch film and the growth of curling, and black film and earthing can not penetrate sunlight, bud seedling yellow death.And the crop seedling relies on the automatic rupture of membranes of bud scale penetration power to form seedling.And it is very fast to cover the thin soil layer water evaporates on the film, and weed seed can not germinate.Even because of precipitation causes showing native moisture retention, but show native water rapid evaporation, weeds can not be survived, finally reach the weeding purpose.Simultaneously, because the following resistance effect of film of soil, make that moisture is not evaporated under the film, crop root has sufficient moisture to be used for growth, thereby reaches the effect of water-saving and synergistic.
The method of the invention specifically describes as follows: a kind of method of preventing and removing weeds and reducing evaporation in farmland, and level land according to a conventional method, sow, on soil after planting, cover black mulch film, evenly cover one deck fine earth on the film.Wherein, sowing depth is requirement routinely, but will consider soil thickness on the film.
Black mulch film contain carbon black pigment 2%～3%, light transmittance 1%～3%, thickness are 0.008～0.01mm; Cover the thickness 1～2cm of fine earth on the mulch film.Used mulch film is easy degradative plastic film, can contaminated soil.
The beneficial effect that the present invention obtains is: weed seed is limited under the black mulch film after germinateing, and can't obtain illumination, finally can be dead.Because it is fast to cover the thin soil layer water evaporates on the film, weed seed can not germinate, or also can be dead because of arid after germinateing, and finally reaches the weeding purpose.Because film covers and do not have breakage except that the seedling sky under the soil of full field, reaches the water conservation water-saving result, strong wind also can not occur and take off film.Simultaneously, because the following resistance effect of film of soil, make that moisture is not evaporated under the film, crop root has sufficient moisture to be used for growth, thereby reaches the effect of water-saving and synergistic, evidence, and water-saving result reaches 65%-75%.
Embodiment
Following examples are used to illustrate the present invention.
Example 1
With the lily cultivation is example.Before the sowing, use sufficient base fertilizer, plough deeply soil, with the clay fertilizer mixing, do furrow, general wide 2m of furrow or the wide integral multiple of film are about the long 20m of furrow.After carrying out furrow, furrow face table soil is whole broken, leveling.Water once permeablely before the sowing, sow seedling then, arrangement furrow face.After the furrow face is smooth, cover the easy degradation plastic mulch of one deck black, it contains carbon black pigment 2%～3%, and light transmittance 1%～3%, thickness are 0.01mm.Evenly spread the fine earth that covers 1cm thickness on black mulch film, wait is emerged.Field management work after emerging is with general management.
Example 2
Still be example with the lily cultivation, wherein, used black plastic ground film thickness 0.008mm contains carbon black pigment 2%～3%, and light transmittance 1%～3% spreads on the film and covers fine earth thickness 2cm, and other condition is identical with embodiment 1.
Example 3
Still be example with the lily cultivation, wherein, black plastic ground film thickness 0.009mm contains carbon black pigment 2%～3%, and light transmittance 1%～3% spreads on the film and covers fine earth thickness 1.5cm, and other condition is identical with embodiment 1.
Example 4
With the sword lily cultivation is example, and wherein, black plastic ground film thickness 0.01mm contains carbon black pigment 2%～3%, and light transmittance 1%～3% spreads on the film and covers fine earth thickness 1cm, and other condition is identical with embodiment 1.
Example 5
With the sword lily cultivation is example, and wherein, black plastic ground film thickness 0.008mm contains carbon black pigment 2%～3%, and light transmittance 1%～3% spreads on the film and covers fine earth thickness 2cm, and other condition is identical with embodiment 1.
Example 6
With the sword lily cultivation is example, and wherein, black plastic ground film thickness 0.009mm contains carbon black pigment 2%～3%, and light transmittance 1%～3% spreads on the film and covers fine earth thickness 1.5cm, and other condition is identical with embodiment 1.
