described, at bottom of trench central authorities deep placement compoiste fertilizer, after laying dropper, re-lay conventional traditional mulch film, on the bottom of trench facial mask, envelope is pressed 2cm left and right hack bits, and compacting film ditch, be layered on the exit or entrance of a clitch by the film limit
Figure G200810001459801D00036
along limit, then on the ditch counterdie by the distance between rows and hills requirement, the punching dibbling, (with good conditionsi can be when the groove face overlay film, by the distance between rows and hills requirement, after punching on film, available water imbibition adhesive sticker paper tape, want the refinement amount to cement in fenestra central authorities by distance between rows and hills in seed, together with dropper, together cements under bottom of trench central authorities overlay film
Figure G200810001459801D00037
accurate plastic film mulch again, and envelope is pressed the thick hack bits of 1.5-3cm on bottom of trench kind row film.To wearing voluntarily the weak small-sized seed of film Emerging ability, as chrysanthemum, beet, rape etc. are punched, glue kind of a plastic film mulch grave mound like this, also can obtain the automatic emergence rate in good field.<2 > illustrate in accompanying drawing 3 shown in right side, dense planting crop trench planting mode for ridge overlay film in high ridge bow film ditch, be not suitable with on film the program request of punching because dense planting Plants distance is little, so needn't overlay film to the seed furrow bottom surface, two sides by plastic mulching at high furrow, the film limit is pressed under the vertical dark 3-5cm in furrow base, the sowing of ditch bottom surface with in front 1<2 > described method do not repeating.<3 > furrow side overlay film in the bow film is advisable with black film, be conducive to weed eradication, need take in time the bow film off when rasputitsa temperature recovery to 18 ℃, the ridge phase is closely sealed in the bottom of trench plant growth, ditch ridge face has plastic mulching to reduce the open country water evaporates, again rainwater and evaporation moisture content is all combined in to moist plant growth in ditch simultaneously.Be well suited for the plantation application of semiarid zone dense planting crops.
4, the above is three kinds of modes of Planting Crops in high ridge bow film ditch, characteristics are respectively arranged: in the first high ridge bow film ditch not overlay film directly plant, dropping into the overlay film cost does not increase, simple, rare crop beet, the pigment chrysanthemum, the sowing time of cotton, comparable traditional flat planting mode was done sth. in advance the first quarter moon left and right, in bow film ditch, the field emergence of plantation reaches more than 98%, seedling process of growing under the protection of bow film is obviously accelerated, particularly the bow such as dense planting crop wheat upland rice film cover time less than is one month, effectively promoted the process of growing of seedling, extended ear differentiation period, lay good basic condition in strong sprout for achieving higher output.Also recycling after the bow film reclaims, effectively reduced production cost.In the second high ridge bow film, overlay film is worn the film type of seeding of emerging voluntarily, to sowing row table soil, require plain, mulch film requires degradable mems thin film (thickness is at 0.002-0.005mm), plant earthing on the row film and want broken carefully abundant, cause is to wear voluntarily film to emerge, little to the overlay film damage, the insulation soil moisture conservation is effective, strengthened the drought-resistant ability of seedling, be applicable to insemination and emergence phase arid without rain or northern area short of rain, large tracts of land mechanization, apply automation plantation agricultural region, the mulch film dense planting crop such as the wheat upland rice application under-film drip irrigation implantation methods of emerging voluntarily particularly, it is economized and plants, the saving of labor, the water-saving and yield-increasing effect is more remarkable.Bunch plating method for planting on coverlay in the third bow film ditch, this method is less demanding to mulch film, and the conventional plastic mulching of available tradition, for the fenestra that improves program request on conventional film and the phenomenon of planting the bud Influence of Displacement and emerging.The inventive method proposes when plastic film mulch, after punching by corresponding trench sowing overlay film distance between rows and hills requirement on film, available water imbibition adhesive sticker paper tape, by distance between rows and hills, want the refinement amount to cement in fenestra central authorities in seed, together with dropper, together cement under bottom of trench central authorities overlay film, guaranteed that like this seed no longer is subjected to displacement phenomenon, by the hack envelope, press tight, after dripping under film, under the protection of bow film, the very fast moisture absorption rudiment of seed in the fenestra growth of automatically emerging, for wearing voluntarily the weak beet of film Emerging ability, the pigment chrysanthemum, onions etc. adopt this method film-covering planting, can obtain the automatic emergence rate in field preferably.For the dense planting crop that is not suitable with punching program request on film; adopt Gou Long side overlay film, the plantation of bottom of trench direct-seeding; early spring is under the protection of bow film; the growth of emerging after the crop-planting groove face drips is also fine; after Gou Long covers black film in side; have good weed eradication and collection rain irrigation effect, be applicable to In The Semi-drought Region of Northern and plant early spring such as wheat, upland rice, vegetables etc.The advantages such as the interior Planting Crops of bow film ditch has emerges, and growth of seedling is fast.
5, in high ridge bow film ditch, plantation is erected high ridge because of trench digging, in ditch, fertile table soil has been got and has been built on high ridge, to focus at seeding time sowing in ditch using of deep placement compoiste fertilizer in the ranks for this reason, when repeating the high ridge trench planting, consider the crop rotation of ditch ridge, the first crop crops straw is combined in ditch, coordinate and apply base manure, on the Yuan Long ridge, trench digging is tight by stubble envelope pressure in primitive groove, can greatly reduce so traditional farming level, has realized the crop rotation in local soil.Particularly continuous cropping crop growing spots for many years, accomplish that the local crop rotation in ditch ridge is conducive to reduce the harm of disease worm, improves the crop yield level.
6, the problem of the common attention of three kinds of modes of plantation in the high ridge of crops bow film ditch:<1 > trench digging ridging must reach maximum height, and the ridge side surface is plain, sowing forms obvious arc film behind overlay film press mold limit, to be conducive to keep the crop seedling growing space of emerging in bow film ditch.<2 > windproof solid film waistband must fasten admittedly, and it is the basic assurance of bow film.<3 > position in the roof leaking water hole of bow on film and aperture, pitch-row must be suitable, in order to avoid collection rain is pressed, falls into the bow film, affect seedling and grows.<4 > prevent from bending high temperature in film and scald seedling, the same day, the temperature degree went up 18 ℃-20 ℃ the time, must be noted that to open the cooling of part film limit, or took off in time film and put seedling and reclaim the bow film.<5 > the deep placement seed manure of ditch bottom surface is capable will avoid overlapping with the sowing row, and fertilization depth is below 10cm, and the seed-fertilizer applying amount is unsuitable excessive, in order to avoid the excessive seed sprouting that affects of seed manure.<6 > the water imbibition adhesive sticker paper tape of cementation seed, require water imbibition, cementation to be eager to excel, and can fully seed and mulch film be cemented admittedly, after water suction, do not come unstuck, and makes seed and mulch film cementation for whole, after seed moisture absorption rudiment, at first penetrates mulch film, then pushes up soil and emerge.The automatic emergence rate in field that so fully assurance is emerged voluntarily and sowed.
