The invention provides the high-yield planting method for winter corn which is high in germination rate, strong in frost-resistance and strong in water and fertilizer absorption. The high-yield planting method for winter corn is characterized by comprising the following steps of: I, a seeding stage: a frostless region must be selected for planting winter corn; II, seeding specification and density: for high-yield culture of winter corn, the seeding specification is specified cultivation with wide and narrow row spacing, and a wide and narrow row spacing compound region is determined due to monoculture or intercropping; III, selection of a parcel of field suitable for planting winter corn: a parcel of field which has irrigation and drainage conditions and is loose in soil are selected to plant winter corn, the soil is maintained moist frequently, and robust growth of plants is promoted; and VI, film coverage: as the air temperature is relatively low for winter corn, the field capacity of the soil is reduced as a result of ending of rainy seasons, less rainfall and much wind.
Description
Technical field
the invention belongs to planting technology field, particularly relate to the culture technique of Winter Corn.
Background technology
winter Corn belongs to anti-season crop, and root system development is poor, and absorb liquid manure ability more weak, grow be not as vigorous as Summer Maize, same kind, winter sowing is shorter and smaller than summer sowing plant, and breeding time extends.In addition, Winter Corn is afraid of frost, as vegetative period meets frost, and the gently then underproduction, heavy then No kernels or seeds are gathered, as in a year of scarcity.
winter Corn reason for low yield is analyzed; Low temperature disaster is the principal element corn affecting Winter Corn output is the warm crop of a kind of happiness, and the time of infertility all needs higher temperature, and its biology lower limit temperature is 6 DEG C, and freeze injury temperature is-2 DEG C ~ 3 DEG C.Dehong all the year round the sunshine time long, temperature is high, four seasons fuzzy, and temperature still can present regular change along with the change in the four seasons.But existing Winter Corn implantation methods also imperfection, the problem that the germination rate being easy to occur for Winter Corn is low, fearness frost, water suction fertilizer sucting ability are weak does not also solve completely.
Summary of the invention
the present invention is exactly for the problems referred to above, provides the high-yield planting method of a kind of Winter Corn that a kind of germination rate is high, Freezing hardiness strong, water suction fertilizer sucting ability is strong.
to achieve these goals, the present invention adopts following technical scheme.
the high-yield planting method of Winter Corn, is characterized in that: comprise the following steps.
one, seedtime; Plantation Winter Corn must select frostless area, understands the local minimum air temperature simultaneously and occurs period, arrange sowing time properly.Be subject to less for making Winter Corn or not by freeze injury, sow the climate and other natural phenomena of a season and be generally late October to November.
two, specification and density is sowed; Winter Corn high-yield culturing, sowing specification is the cultivation of wide-and narrow-row specification, and wide-and narrow-row composite band is determined depending on nonoculture or intercropping.Nonoculture, narrow row is 50 centimetres, narrow row is planted 2 row corns, and line-spacing is 40 centimetres, spacing in the rows 13 ~ 17 centimetres, wide behavior 90 ~ 93 centimetres, every mu of nursery 5580 ~ 7140 strain; Intercropping, narrow row 42 centimetres, plants 2 row corns, line-spacing 33 centimetres, spacing in the rows 13 ~ 17 centimetres, wide row 133 centimetres, widely plants 3 row soybean or 2 row potatos in the ranks, and corn every mu seedling has 5700 strains.
three, the field of suitable planting Winter Corn is selected; Select have the field of irrigation condition, loosing soil to plant, and often keep ground moistening, promote robust plant growth.But can not select that physical features indentation, subterranean water level are high, the plantation of the plot of impeded drainage, otherwise root system development can be made bad, plant slight of stature, leaf turns to be yellow, and makes female tassel depauperation and can not pollinate, and causes empty not plump, low yield or without receipts.
four, epiphragma; Winter Corn because of temperature lower, water-retaining quantity among field of soil along with Withdrawal, rainfall is few, wind is many and reduce.For this reason, heat moisturizing by epiphragma and seem extremely important.Related tests data shows, more than Winter Corn epiphragma and not epiphragma output great disparity twice.The field of epiphragma requires that soil block wants thin, and field will flatten, and during epiphragma, film will collapse tightly, and the blinding of film surrounding will compress but should not cover too much.Seeding method has two kinds: one to be after planting epiphragma, and this formula of broadcasting can be directed, and can seed is pressed onto on the immature soil, emergence rate be high, and orientation ratio can reach more than 90%.But notice that broadcasting latter about 5 days carries out rupture of membranes, otherwise burning seedling can be caused.Two is first ditching-fertilizing blindings, then epiphragma, to burrow sowing, broadcast rear fine earth and hole is built after epiphragma with pointed stake rupture of membranes, and this formula of broadcasting can reduce rupture of membranes man-hour, can avoid burning seedling, can guarantee full stand, but orientation ratio be lower.
further, to fill the gaps with seedlings thinning.When maize seedling grows to 3 ~ 4 leaves, close filling a vacancy be moved, transplantation with soil, water sufficient normal root water; Thinning will go weakly to stay strong, and size is even, and strain in strong sprout 1 is stayed in every cave.
again further, method of keeping a full stand of seedings is, the work of keeping a full stand of seedings in seedling stage comprises insect protected, take precautions against drought, prevent waterlogging and birds and beasts harm etc.
again further, seed manure is executed.To weeds be uprooted after Qi Miao, promote that root system is pricked deeply.Execute seedling fertilizer to carry out in conjunction with intertillage, execute urea 5-10kg for every mu, weak seedling is mended and executes 1 quick-acting liquid nitrogenous fertilizer.Now as soil drought should in conjunction with pouring water, but it is too much unsuitable to pour water, and seedling stage avoids ponding, ground moistening.
beneficial effect of the present invention.
the present invention in order to reach the object of Winter Corn high yield, the every technical measures of integrated use.First, kind is the key factor realizing Winter Corn high yield; Secondly, the sowing climate and other natural phenomena of a season, soil fertility, fertilizer practice, moisture condition, quality of the workforce, farming level etc. all have a significant impact Winter Corn output, form rational cultivation mode.Make that the plantation germination rate of Winter Corn is high, Freezing hardiness is strong, water suction fertilizer sucting ability is strong.Thus improve household economy income.
