Description
Technical field
The present invention relates to proportion of crop planting field, particularly a kind of booth spring Carrot method.
Background technology
Carrot another name carrot, red, cloves radish, Jin Sun etc.Belong to the mutation of Umbelliferae Daucus cicely kind carrot, 2 years raw herbaceous plant.Carrot likes nice and cool environmental condition, and damage by disease and insect is few, adaptability and wide, can cultivate throughout the country.Edible part is loose fleshy root, and fleshy root is rich in sucrose, glucose, starch, carotin and potassium, calcium, phosphorus etc.Every 100 grams of fresh weights are containing 1.67-12.1 milligram carotin, and content higher than tomato 5-7 doubly, resolves into vitamin A through gastrointestinal disturbances after edible, can prevent nyctotyphlosis and respiratory disease.Can stir-fry and eat, cook, saucing, to pickle.Storage tolerance.Be distributed in all over the world, all there is cultivation in the South China north, and output accounts for root vegetables second.
Carrot conventional method is autumn culture, produces supply half a year a season, is fed to 3 ~ April of Second Year from October always.On market, after April, carrot supply is fewer, and the market price is higher.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of booth spring Carrot method, and technology is simple, small investment, saving of labor, save trouble, and not having disease, insect pest, is a spring greenhouse cultivation pattern be worthy to be popularized.
For achieving the above object, a kind of booth spring Carrot method that the present invention proposes, it comprises the steps:
One, soil conditioner is prepared: soil conditioner is prepared by the component raw material of following weight portion and obtains: sugarcane stalk 10-15, wheat stalk 25-40, pond sludge 35-48, straw 22-26, cottonseed cake 6-8, mushroom slag 6-8, weathered coal 10-12, chrysanthemum cinesariaefolium 13-16, zinc sulphate 0.2-0.3, manganese sulphate 0.02-0.03, matrine 1-2, ammonium molybdate 0.2-0.3, frutus cnidii 3-4, peppermint oil 2-3, urea 3-4, sodium carboxymethylcellulose 3-5;
Two, Fruit variety: spring cultivation should select that cold resistance is strong, vegetative period is short, the kind of resistance to bolting.Select the kind that the red skin of suitable market comsupton, red meat and newel are entirely red.As improved the kinds such as five cun, black field, red ginseng king.
Three, base fertilizer is used sufficient, Potassium: often produce 5000kg carrot and need absorbed nitrogen 16kg, phosphorus pentoxide 6.5kg, potassium oxide 25kg.If nitrogenous fertilizer is too much or potassium deficiency can cause leaf growth excessively prosperous, affects fleshy root and expand, thus reduce output, tip of a root cripetura or afterbody can be made simultaneously to send out point, reduce commodity value, execute the fertile 2500kg that becomes thoroughly decomposed, soil conditioner 300kg, ash 100kg for every mu.
Four, optimum period meticulous sowing, guarantee to broadcast full stand:
Carrot seed seed is little and have the protection of keratin film, difficulty of not only germinateing and to push up native power weak.If sowed dark, easily " vexed bud "; If sowed shallow, between sowing time, Evaporating capacity was strong, and easily rained in torrents, and was easy to " returning bud " or " bat seedling ".Broadcast full stand if want, must accomplish before broadcasting, the seta on seed to be rubbed with the hands only, after broadcasting, carry out covering cooling moisture-retaining.Being advisable to early August sowing by the end of July in East Platform area, must not be later than August 22.Late sowing output obviously declines.General drill spacing 20 ~ 25cm, every 667m2 broadcast clean seed 350g, and blinding 1.5cm is thick, water vola water.Every 667m2 Pendimethalin 100mL or prometryn 100g, to water 40kg, evenly sprays furrow face, management of weeds.After planting cover broken straw grass or sunshade net along broadcasting row, keep soil moisture, anti-heavy rain is washed away, and falls ground temperature simultaneously, is beneficial to out full stand.
Five, enhance field management
1, seedling thinning and final singling: timely seedling thinning after carrot emerges, prevents seedling from altering height.Seedling 2 leaf phase seedling thinning 1 time; Seedling 1 time during 3 ~ 4 leaves, spacing 4 ~ 5cm; 5 ~ 6 leaf phase final singlings, spacing 9 ~ 12cm.
2, Reasonable Regulation And Control moisture: keep ground moistening before emerging, be beneficial to germination and emergence.Seedling Stage keeps soil to see dryly seeing wet, promote radicula normal growth.Soil overdrying, root is pricked not go down, excessively wet, the easy rotten tip of a root.Must irrigate, to improve output when fleshy root expanding stage meets arid.Keep common dry rare wet, moisture supply is relatively stable, must guard against large doing and waters greatly.Excessively wet after first overdrying, carrot is easy to crack; First cross wet rear overdrying, carrot rough coat meat is aging.Peasant household with good conditionsi can lay flexible pipe drip irrigation on furrow, the wide 2m of furrow, lays flexible pipe 2, each drip irrigation 7 ~ 9m along furrow direction
3.
3, topdress short long, appropriatenessization is controlled: fleshy root expanding stage sees that seedling topdresses 1 ~ 2 time, and each every 667m2 executes urea 5 ~ 10kg, potassium sulfate 7.5 ~ 10kg, and helps strong plain 30mL to the sprinkling of 30kg water with 25%, and promotion fleshy root expands.
4, earth up: for improving carrot quality, must earth up when fleshy root expands, light turns green to prevent carrot fleshy root from seeing, occurs " blue or green head " and affects commodity in good time.
5, diseases and pests controlling is done well: note seedling stage selecting 70% thiophanate methyl, 800 times of liquid+75% tpns, 600 times of liquid to prevent and treat leaf blight, black spot.Soft rot harm fleshy root, killed part is softening rots, and juice is excessive, foul smelling, should remove diseased plant in time; And at the initial stage of a disease with 72% agricultural streptomycin sulphate 3000 ~ 4000 times of dilutions or new phytomycin 4000 times dilution liquid irrigating root or basal part of stem is sprayed.Select pymetrozine, cyhalothrin anti-to eliminate aphis in time, nocturnal moth class insect.
Six, prevention and control physiological disturbance
1, discrimination root, namely fleshy root branching, is commonly called as wooden fork root.To be destroyed due to main root growing point or its growth is suppressed, and caused caused by lateral root growth expands.The lopsided root that lateral root growth expands and formed, has one or more to branch.Induction morbidity factor, one is use the fertilizer fully do not become thoroughly decomposed, or it is too concentrated to impose chemical fertilizer, or from root too close to, cause main root " burn "; Main root is bitten by soil insect, or the farming operation such as to be hoed the fields is accidentally injured, and can not continued growth, side root all can be caused to expand and form discrimination root.Two is that plow layer is shallow, or soil property too sticky heavy, to harden and stone, tile etc. in soil makes main root not prick normally down, and rear side root grows gradually to expand and forms wooden fork root.Prevention and controls, one be after front stubble results with large tractor deep ploughing soil 25 ~ 30cm, implement high bedding cultivation, pick up except the stone in soil, tile etc. affect main root under the barrier pricked.Two is use the fertilizer fully become thoroughly decomposed, and fertilising should rationally and execute even; Timely with chlopyrifos, isazofos control soil insect, main root is escaped injury.
2, root is split: Carrot middle and later periods fleshy root cracking, interior tissue exposes, and is called and splits root.Breach length and the degree of depth differ, and time serious, lobe length almost can pass through fleshy root.The generation of this disease, except reduction output and commodity, also makes fleshy root not storage tolerance, and easily causes soft rot to occur.The cause of disease is that soil moisture supply inequality causes.Meet high temperature and drought weather early stage at Carrot, if soil moisture is not enough, then the cortical tissue of fleshy root is aging, when the middle and late growth stage temperature, moisture are suitable for, the parenchyma cell of fleshy root expands once again, and cortical tissue can not correspondingly grow, and causes fleshy root to ftracture.Preventing and treating key is expand the stage at fleshy root, and soil should keep moistening, accomplishes that neither overdrying wets only.In addition, carrot young leaves growth retardation during calcium deficiency, the bent browning of leaf roll is withered, general available ca treasured 800 ~ 1000 times or 0.3% ~ 0.5% calcium chloride solution carry out foliage-spray, every 667m2 consumption 40 ~ 50kg.During carrot boron deficiency, young leaves is light green, and leaf top is outwards rolled up, deformity, and lobus cardiacus is withered, often can spray 0.2% borax or BAS 40 ~ 50kg by 667m2.Spray leaf fertilizer should be selected in the cloudy day or fine day carries out in calm afternoon.
Seven, gather: 5, June, carrot is gathered in batches, cleans, classification, 10 ~ 15kg quantitative package go on the market, early stage by peasant cooperative society take the lead supply market, big and medium-sized cities, middle and later periods supply dewatering vegetable factory or sauce factory, discrimination root, splits the substandard products supply dairy farms such as root.Every 667m2 can produce carrot 5000kg, the output value 3000 ~ 5000 yuan.
