Abstract

The invention discloses a method for planting spring carrots. By reasonably fertilizing base fertilizer, antibacterial and disease-resistant performance of carrot plants is improved greatly; by seed treatment, resistance of the plants is further improved, environmental adaptability is improved, and disease incidence is lowered.

Description

A kind of spring carrot implantation methods

Technical field

The present invention relates generally to agriculture field, relates in particular to the implantation methods of a kind of spring carrot.

Background technology

The growth cycle of carrot must be through 2 years from being seeded into seed maturity, and the 1st year is vegetative growth phase, grows up to meat taproot.In south, can survive the winter by open country, the north is preserved and is survived the winter; Under low temperature, pass through vernalization stage in the winter time.Field planting in spring in the 2nd year, bolting, bloom, knot, complete reproductive stage.The phasic development of carrot belongs to green body vernalization type, and seedling is just accepted low temperature to the qualitative change impact of growing after reaching a certain size.Therefore summer, autumn and late spring all can cultivate, too early, seedling age reaches after a certain size for spring sowing, can be because accepting compared with long low temperature bolting in advance.

Vegetative growth stage 80～140 days, germination period approximately 10～15 days, Seedling Stage approximately 25 days, leaf peak of growing season (also crying the rosette stage) approximately 30 days, is thereafter fleshy root vegetative period, 30～70 days.Seed can be sprouted at 4～6 ℃, and the suitableeest germination temperature is 20～25 ℃, and the growth of leaf portion has stronger adaptability, and taproot expanding stage requires 13～23 ℃, and night, temperature was 13～18 ℃.Can be arranged in the month that temperature is higher or lower seedling stage, makes the month in optimum temperature product vegetative period.Carrot requires the deep sandy soil of soil layer, and pH5～8 are the most suitable, and requiring soil moisture is 60～80% of water-retaining quantity among field of soil.Antecedent moisture too much affects taproot and expands growth, later stage water deficient, and taproot also can not fully expand.Sticky heavy soil, the base manure fully not becoming thoroughly decomposed and plough deeply carefullyless, all can hinder taproot growth, produces fork root.

Summary of the invention

The object of the invention is exactly in order to improve in the planting process of tradition spring carrot, and the phenomenon that various damage by disease and insect are serious to the destruction of plant provides the implantation methods of a kind of spring carrot.

The present invention is achieved by the following technical solutions:

Spring carrot an implantation methods, comprise the following steps:

(1) land management: to select that soil layer is deep, the soil is porous fertile, on the sunny side, be rich in humus and well-drained sand loam, mu is executed 2500-3000 kilogram of base manure, it is characterized in that the mass percent of each component is: animal wastes 70-80%, quicklime 6-8%, weathered coal 5-6%, rock phosphate 2-4%, rice hull ash 6-8%, garlic powder 1-2%; Animal wastes are stacked, and stacking is highly 1.6-2m, and digging pit in centre, inserts quicklime and garlic powder, adds water to spill-over, stacks 30-40 days, with weathered coal, rock phosphate, rice hull ash mix and blend;

(2) vernalization sowing: 50% methamidophos wetting powder is mixed with the cassia oil of its quality 2-4%, seed dressing after stirring, under stirring and adjusting, dropping temperature is the water of 30-35 ℃, the consumption of water is 4-6 times of 50% methamidophos wetting powder, dropwise and with clear water, rinse well afterwards, wet towel parcel, be placed at 25-30 ℃ of temperature vernalization 3 to 4 days, with clear water, rinse 1 time every day therebetween, after showing money or valuables one carries unintentionally, 80%-90% seed can sow, sowing time is that late March is to early April, the line-spacing of sowing is 20-30 centimetre, broadcast the rear thin fine earth of one deck that evenly covers, covering with plastic film, water sufficient water,

(3) field management: after seedling all sprouts, mulch film is taken off, in seedling stage, should carry out 2 thinnings, the 1st thinning carried out when 1-3 sheet true leaf, the 2nd thinning carried out when 3-5 sheet true leaf, after thinning, get final product final singling, spacing is generally at 12-14cm, during thinning, to note weeding with a hoe, within 5-7 days after final singling, water water for the first time, mu is executed urea 4-7kg, potassium dihydrogen phosphate 3-4kg, ammonium nitrate 1-2kg, at fleshy root, expands the initial stage, water for the second time, mu is executed ammonium sulfate 6-8 kilogram, uremic 3-4 kilogram, calcium dihydrogen phosphate 2-3 kilogram;

(4) gather in the crops: when ripe, show as not regrowth of blade, lose young leaves, lower blade flavescence by stages in good time.

Advantage of the present invention is:

Implantation methods of the present invention, by reasonably using base manure, has improved the antibacterial disease resistance of carrot plant greatly, by seed treatment, has also further improved the resistance of plant, has strengthened the adaptability to environment, reduces the incidence of disease.

Embodiment

Embodiment 1

Spring carrot an implantation methods, comprise the following steps:

(1) land management: to select that soil layer is deep, the soil is porous fertile, on the sunny side, be rich in humus and well-drained sand loam, mu is executed 2500-3000 kilogram of base manure, it is characterized in that the mass percent of each component is: animal wastes 70-80%, quicklime 6-8%, weathered coal 5-6%, rock phosphate 2-4%, rice hull ash 6-8%, garlic powder 1-2%; Animal wastes are stacked, and digging pit in centre, inserts quicklime and garlic powder, adds water to spill-over, stacks 30 days, with weathered coal, rock phosphate, rice hull ash mix and blend;

(4) gather in the crops: when ripe, show as not regrowth of blade, lose young leaves, lower blade flavescence by stages in good time.Empirical tests, is used method damage by disease and insect incidence of the present invention lower than 1.6%.
