G () clears up residual film: after clover results, and the residual film of clearing and retrieving of doing everything possible, reduces " white pollution ".
On the basis of such scheme, adopt the field management pattern consistent with traditional establishment of alfalfa grassland.
Below vocabulary of terms is made an explanation:
Clover: for being the common name that grass family clover belongs to (Medicago) plant, a kind of perennial herbaceous plant that blooms.Wherein foremost is alfalfa (Medicago sativa) as herbage.China cultivation clover mainly with haying, silage fodder or be used as the herding with grass of native pasture.
Clover field (alfalfa land) is by the sown pasture of perennial alfalfa planting, season of growth on this meadow from annual mid-March-by the end of October, be the production period of Alfalfa product; November to Second Year early March is the winter dormancy phase, and this time is idling period.
Fertilizer (manure) is for natural organic matter is through a class fertilizer of microbial decomposition or fermentation, and also claim farmyard manure, Soil building is effective, could must be absorbed after microbial decomposition transforms by plant.Conventional natural manure kind has green manure, night soil, barnyard manure, compost, makes compost, biogas manure and sludge and refuse etc.The present invention's fertilizer used is barnyard manure.
Wheat grown along film sides (film skirting furrow trench planting) is a kind of technology of Furrow sowing between two mulch film sides, and wheat grown along film sides has and improves ground temperature, prevents from hardening, retains and conserve soil moisture, favourablely to topdress, easily takes off film, obtains the advantages such as high yield.The present invention's mulch film used is that 40cm is wide, 0.25mm is thick.
The present invention improves on the basis of existing implantation methods, and main improvement is:
(1) planting patterns is improved.Planting patterns is in the past naked broadcasting, and namely directly sows on soil, this seeding method problems faced be must before broadcasting to soil weed killer herbicide carry out closing prevent from broadcasting after weedy.And wheat grown along film sides technology does not need to broadcast front weed killer herbicide closes the effect that namely soil can play weed control, the use of weed killer herbicide can be reduced again.
(2) in planting technology, more meet the technology of nuisanceless alfalfa cultivation.The advantage of wheat grown along film sides technology is a lot, is first after clover results, directly can uncover mulch film from the ridge back of the body, avoid film as film-covering planting technology and be blended in grass product; Next is that wheat grown along film sides decreases the pollution of area source brought because repeatedly using weed killer herbicide and soil, is beneficial to and produces organic Alfalfa product, ensure herbvore livestock product safety; 3rd, wheat grown along film sides is conducive to the soil moisture conservation in clover field, decreases the irrigation frequency in clover field, and then reduces production cost, improves the productivity effect of clover.
The present invention not only effectively controls the weed growth in clover field, and finds through research, and the clover seedling rate of wheat grown along film sides and output are all higher than general planting.
The ridge back of the body exposed between each row of clover can be covered by wheat grown along film sides, keep the sprouting that low temperature facilitates alfalfa seed, prevent moisture to evaporate and serve good soil moisture conservation effect, the ecological niche occupying weed growth makes weeds lose the space of growth, what decrease weed killer herbicide uses the pollution reducing soil in ALFALFA PRODUCTION, decrease irrigation frequency and reduce ALFALFA PRODUCTION cost, and owing to being the wheat grown along film sides using thick film to carry out, can not film strips be entered in alfalfa products during clover results, and can directly the film that ridge is carried on the back directly be uncovered after clover results, can not bring " white pollution ".
Why the present invention uses wheat grown along film sides instead of film-covering planting, is because clover is the non-bunch planting of drilling, and overlay film is unfavorable for that clover emerges management, and film strips easily enters among alfalfa products by film-covering planting.Select the thick film of 0.25mm, be in order to prevent film broken be difficult to pick up in ground cause " white pollution ".
Adopt the inventive method compared with traditional clover general planting, traditional clover field is huge on alfalfa growing impact in seedling stage in plantation weeds then, and generally need to spray 2-3 weed killer herbicide, namely soil closed by pre-plant herbicide, broadcasts and sprays blade face weed killer herbicide rear seedling stage.This is to the pollution increased the weight of clover field, and adds the seedling rate of clover.Compared with prior art, wheat grown along film sides improves 31.7% than general planting clover seedling rate.And in clover annual production, improve 19.8%-152.6% than general planting.Wheat grown along film sides clover technology provided by the invention achieves the object controlling clover field weed, achieves clover field high yield and non-polluted planting unification mutually, achieves the target of environmentally friendly ALFALFA PRODUCTION.
