Abstract
The invention provides a cold-bed double-film low-density discharge low-tunnel sweet potato seedling raising method. The cold-bed double-film low-density discharge low-tunnel sweet potato seedling raising method includes steps of 1), deeply plowing lands for raising sweet potato seedlings in autumn and winter and naturally weathering the lands through the winter; 2), leveling the lands in the next spring and making ridged fields on the lands; 3), planting sweet potato seeds, in other words, transversely planting the sweet potato seeds in soil in the ridged fields, and covering the ridged fields with mulching films; 4), covering the ridged fields with arched top films. The sweet potato seedlings can be uniformly distributed and grow on bodies of the sweet potato seeds, the quantity of sweet potato seedlings with transplanting value can be increased, and accordingly the sweet potato seed utilization degree can be increased. Besides, nutrition can be uniformly absorbed by the sweet potato seedlings, the seedlings are strong, the seedling recovery speed is high after the sweet potato seedlings are trimmed and transplanted, and the survival rate of the strong seedlings is high. The cold-bed double-film low-density discharge low-tunnel sweet potato seedling raising method has the advantages of scientific design, high seedling emergence quality, uniformity in seedling emergence and high post-transplanting seedling recovery speed.
Description
Technical field
The present invention relates to a kind of Ipomoea batatas seedling-cultivating method, specifically, related to and be a kind ofly applied to the two film thin plantings of Ipomoea batatas cold bed that outdoor large area cultivates and discharge little shed seedling-cultivating method.
Background technology
In conventional red planting potato method, all adopt hotbed plantation, on the soil that imposes the hot things of moisture in the soil such as farmyard manure or accumulation wheat straw, plant Ipomoea batatas kind.The defect that the seedling raising manners of hotbed plantation potato kind exists is that the too high Ipomoea batatas kind that easily burns out of soil temperature, easily causes potato kind infection process besides.
Moreover, in existing Ipomoea batatas seedling raising manners, conventionally by Ipomoea batatas kind top upward root plant in soil down, and Ipomoea batatas kind and ground level are 30 ° to 45 ° inclination angles.Because Ipomoea batatas kind apical growth gesture is strong, emerged in top overstocked, cause seedling matter thin and weak, make to have and transplant the Ipomoea batatas seedling being worth and reduce, and Ipomoea batatas seedling after transplanting, to return seedling slow, survival rate is low, causes the waste of potato kind.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, thereby provide a kind of design science, the quality of emerging is good, return the two film thin plantings of the fast Ipomoea batatas cold bed of seedling after emerging evenly, transplanting discharges little shed seedling-cultivating method.
To achieve these goals, the technical solution adopted in the present invention is: the two film thin plantings of a kind of Ipomoea batatas cold bed discharge little shed seedling-cultivating method, comprise the following steps: 1) by the soil of growing seedlings for Ipomoea batatas, at the autumn and winter season processing of deep ploughing, the weathering of surviving the winter; 2) coming year, the spring leveled land, furrow processed; 3) plantation Ipomoea batatas kind: in the furrow of field, Ipomoea batatas kind is laterally planted in soil, then covering with plastic film on the furrow of field; 4) in field furrow upper cover, establish arch sky film.
Based on above-mentioned, adopt the mode of thin planting horizontally-arranged, the line space of described Ipomoea batatas kind plantation is 30cm to 35cm, plants Ipomoea batatas kind described in 3～5 row in each field furrow.
Based on above-mentioned, described field furrow are not established furrow rib, and described Ipomoea batatas kind is planted in plane soil, and every furrow length is 20m to 25m.
The relative prior art of the present invention has outstanding substantive distinguishing features and significant progressive, specifically, and the utilization of the present invention weathering of surviving the winter, soil aggregate is improved, chesson, and effectively reduce germ and the insect in soil, guaranteed the quality of emerging of Ipomoea batatas seedling.Laterally the benefit of plantation is: Ipomoea batatas seedling is uniformly distributed growth with it Ipomoea batatas is all, makes to have to transplant the Ipomoea batatas seedling being worth and increase, and makes Ipomoea batatas kind utilize degree to increase, and it is even that Ipomoea batatas seedling absorbs nutrient, seedling matter is strong, and to return seedling speed fast after the cutting of Ipomoea batatas seedling is transplanted, and strong sprout, survival rate was high.It is effective that mulch film sky film coordinates soil moisture conservation to heat, and can meet Ipomoea batatas kind root required moisture and temperature condition.The two film thin plantings of this Ipomoea batatas cold bed discharge little shed seedling-cultivating method and have advantages of design science, the quality of emerging is good, it is fast to return seedling after emerging evenly, transplanting.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
The two film thin plantings of a kind of Ipomoea batatas cold bed discharge little shed seedling-cultivating method, comprise the following steps:
1) by the soil of growing seedlings for Ipomoea batatas, at the autumn and winter season processing of deep ploughing, the weathering of surviving the winter; Winter temperature is low, soil aggregate is improved, chesson.Be chosen in that to carry out weathering processing winter be also in order effectively to reduce germ and the insect in soil, guaranteed the quality of emerging of Ipomoea batatas seedling.
2) coming year, the spring leveled land, furrow processed;
3) plantation Ipomoea batatas kind: in the furrow of field, Ipomoea batatas kind is laterally planted in soil, then covering with plastic film on the furrow of field; Laterally the benefit of plantation is: Ipomoea batatas seedling is uniformly distributed growth with it Ipomoea batatas is all, makes to have to transplant the Ipomoea batatas seedling being worth and increase, and makes Ipomoea batatas kind utilize degree to increase.And Ipomoea batatas seedling absorbs that nutrient is even, and seedling matter is strong, to return seedling speed fast after the cutting of Ipomoea batatas seedling is transplanted, and strong sprout, survival rate was high.
4) in field furrow upper cover, establish arch sky film.It is effective that mulch film sky film coordinates soil moisture conservation to heat, and can meet Ipomoea batatas kind root required moisture and temperature condition.
Adopt the mode of thin planting horizontally-arranged, the line space of described Ipomoea batatas kind plantation is 30cm to 35cm, plants Ipomoea batatas kind described in 3～5 row in each field furrow.The benefit of such thin planting is compared with traditional dense planting: the adjacent Ipomoea batatas kind of having avoided transmission dense planting to bring causing makes the hypogenetic situation of Ipomoea batatas seedling because grabbing nutrient, make Ipomoea batatas kind can fully absorb the nutrient in soil, guaranteed growing up strong and sturdy of Ipomoea batatas seedling, also reduced the planting number of Ipomoea batatas kind simultaneously, reduce the artificial planting time, saved cost.
Described field furrow are not established furrow rib, and described Ipomoea batatas kind is planted in plane soil, and every furrow length is 20m to 25m.Like this design simplification to plough processing, have the effect of saving of work and time.
Finally should be noted that: above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit; Although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement the specific embodiment of the present invention; And not departing from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope of request protection of the present invention.
