A kind of have weeding and to hold concurrently the sugarcane full-film mulching and planting technology of insect protected effect
Technical field
The invention belongs to field of plant growing technology, be specifically related to a kind ofly there is weeding to hold concurrently the sugarcane full-film mulching and planting technology of insect protected effect.
Background technology
Sugarcane is as a kind of important sugar [yielding, whole vegetative period, the demand to moisture was larger, but because its economic value added is lower, cane-growing region is mainly distributed in the poor arid hillside field of drought, soil fertility, simultaneously because tillage condition is severe, lack the management method of science, cause weeds in field insect pest serious, greatly have impact on output and the sugar of sugarcane.Traditional plastic mulching cultivation technology can play good protective effect to sugarcane field moisture, but due to only to sugarcane ditch overlay film, sugarcane still has large quantity of moisture in the ranks and scatters and disappears, and easily causes sugarcane production later stage lack of moisture.Existing sugarcane full-film mulching and planting technology (CN101480131A), to to fetch water before overlay film herbicide spraying, the difficulty and far fetch water in the general dried up source of sugarcane field, and destructible medicine layer when carrying out the farm works such as overlay film after herbicide spraying, affect later stage Weed-control effect, the method overlay film efficiency is lower simultaneously, greatly have impact on the kind sugarcane enthusiasm of peasant household; In addition, in prior art, the method for overlay film is all that the mode parallel with planting ditch is laid, and therefore needs when laying to consider to plant ditch width and sugarcane row distance according to overlay film width, and this also reduces man efficiency and the service efficiency of overlay film to a certain extent.
Summary of the invention
In order to solve the shortcoming and defect part of prior art, the object of the present invention is to provide and a kind ofly there is weeding hold concurrently the sugarcane full-film mulching and planting technology of insect protected effect.
The object of the invention is achieved through the following technical solutions:
There is weeding to hold concurrently the sugarcane full-film mulching and planting technology of insect protected effect, comprise following operating procedure:
(1) planting sugarcane field is carried out whole ditching, applies fertilizer, spreads fertilizer over the fields insecticide, sowing, or ratoon sugarcane is carried out brokenly to the ridge pine root and stem of certain plants, applies fertilizer, spreads fertilizer over the fields insecticide;
(2) adopt Sugarcane Herbicidal to carry out full film covering to sugarcane field, coverage rate is 100%; The coverage mode of mulch film is carry out overlay film vertical with planting ditch direction, and overlay film carries out a firming every 3 ~ 5m, and film will be close to and plant ditch, then fetch earth the mulch film hack of planting on ditch compressed, compacting;
(3) field management and sugarcane cut receipts.
Ditching described in step (1) refers to the mode of employing " two plough two rakes " wholely wholely, and deep plough to 35 ~ 40cm, reach dark, loose, thin, flat, during trench digging, furrow width is 90 ~ 120cm, ditch depth 25 ~ 30cm; Hillside is ditched along contour level surrounded by mountains, closed at both ends; The described broken ridge pine root and stem of certain plants will leave sugarcane head 3 ~ 5cm, and the earthing of front stubble sugarcane head is unclamped.
Described fertilising refers to uses slow-release or control-release fertilizer or compound organic and inorganic fertilizer, and every mu of consumption is 150 ~ 200kg, single fertilization before sowing, and covers fertilizer with soil.
Described sowing adopts the planting patterns of single ditch single file or duplicate rows.
Sugarcane Herbicidal described in step (2) refers to containing alachlor, Acetochlor, the third careless amine, isopropyl methoxalamine, isoproturon, atrazine, flutters the polyethylene film of at least one chemical herbicide in Kusatsu, hexazinone and piperazine humulone, the width of weed removal mulch film is 100 ~ 200cm, and thickness is 0.008 ± 0.002mm.
Culture technique tool of the present invention has the following advantages and beneficial effect:
(1) mode that employing of the present invention is vertical with sugarcane planting ditch direction carries out overlay film, overlay film junction is not by the impact of planting ditch width, sugarcane row distance and overlay film width, therefore overlay film operating process is extremely convenient, improve cane planting overlay film efficiency, be 1.5 times of traditional overlay film efficiency under equal conditions, drastically increase the enthusiasm that peasant household uses mulch film;
(2) mode vertical with sugarcane planting ditch direction is adopted to carry out overlay film, just rise and fall between adjacent mulch film handing-over, the film mulching method comparing parallel mode is more firm, decrease natural cause as blown, raining, the destruction to overlay film such as insect pest, ensured the validity of overlay film;
(3) the present invention adopts weed removal mulch film to carry out full film covering to sugarcane field, because weed removal mulch film itself effectively can solve weed problem under film containing weed killer herbicide, without the need to herbicide spraying of fetching water before plastic mulching, decrease the expense of artificial spraying's weed killer herbicide, simple to operate, be beneficial to popularization, and adopt the herbicidal effect of weed removal mulch film better;
(4) scattering and disappearing of sugarcane water consumpation can more effectively be reduced after adopting full film soverlay technique, keep ground moistening, simultaneously because the full film of sugarcane field covers, heating effect is more remarkable, the morning effectively promoting sugarcane kind germinates, morning emerges, ensure that the neat seedling of seedling is strengthened, for sugarcane high-yield provides advantage;
(5) the present invention utilizes the iris action that full film covers, the effect of barrier is served at the mating season mulch film of adult, adult cannot be bred through mulch film, reduce the mating probability of insect, effective reduction insect density, simultaneously due to full film cover to heat effect more remarkable, insect under film can be killed when temperature acquires a certain degree, coordinate insecticide, effectively reduce the harm of sugarcane field insect;
(6) the present invention's disposable employed slow-release or control-release fertilizer or compound organic and inorganic fertilizer before overlay film, continues to provide nutrient during whole sugarcane production, topdresses without the need to taking off film.
