(2) autumn stubble stay foster.Asparagus late August of gathering stops to gather, and enters autumn and stays foster management phase.

4, fertilising: execute fertilizer every year twice.For the first time be spring tender stem take out before death vernalization fertilizer, be for the second time that the autumn of early September is sent out rejuvenation fertilizer.After entering picking time, topdressing, is principle repeatedly gently to execute, and adopts bamboo shoot in earlier stage every 15-20 days, and fertilising is 1 time about 10 days later stages.

5, the extermination of disease and insect pest:

(1) do a good job of it the field health, reduce bacterium source base, remove the field old and feeble withered old female stem and the residual leaf of deadwood, weeds, concentrate and burn, then with the sterilization that carries out disinfection of 600 times of liquid of asparagus green grass or young crops pulvis of 40%.

(2) female stem grows to 5cm when high, luckyly wins+80% than the 500 times of liquid spray medicines of getting profit with 50% pair, and spray in general 5-7 days once will fill spray behind the chance rain.

(3) pest control.Based on biological control, take black old lamp trapping etc.

The invention has the beneficial effects as follows: Zai Pei green asparagus output height in this way, quality is good, remarkable in economical benefits.

Embodiment

1, grows seedlings.In February, the last ten-days period ground temperature adopt little shed to grow seedlings in time more than 15 ℃.Presoaking and germinating at first.300 times of liquid of carbendazim with 50% soaked 12 hours, later on 30 ℃-35 ℃ emerge in worm water 48 hours, after treating the abundant imbibition of seed, seed is leached, put into basin, the wet cloth of lid places 25-28 ℃ environment to carry out vernalization, can sow when seed has radicle about 10% to show money or valuables one carries unintentionally.Secondly, seedbed management and sowing, the selection draining is good, loose, fertile sandy soil is done the seedbed, and use the nitrogenous fertilizer 2000kg that becomes thoroughly decomposed, phosphate fertilizer 30kg, potash fertilizer 15kg, mixed the spreading fertilizer over the fields of the red 2kg of furans, turn over and bury, and carry out nursery bed disinfection for every mu into bed surface, leveling, the seedbed is poured water, is drawn piece and carries out cave point seed, broadcasts back earthing 1cm, and builds little shed.Cultivate strong sprout once more.Can emerge in after planting 5-7 days, temperature is 25 ℃-30 ℃ in the control seedbed, in good time intertill and clean tillage, and every 10-15 days with 600 times of liquid sprays of the blue or green pulvis of 40% asparagus once.

2, field planting: when treating that 3 of seedling terrestrial stem are above, generally get final product field planting in late May.The field planting field is most important to growing of asparagus.Therefore, must select that soil property is fertile, soil layer is deep, treat the plot that rich water is strong.At first plough deeply whole ground, dig the field fertilising, execute the become thoroughly decomposed high-quality fertilizer of getting well and nitrogen, phosphorus, potassium (45%) composite fertilizer of 50kg of 5-6 sides for every mu and be spread in the planting furrow, then, select seedling classification field planting to adopt the M-N-W cultivation, suitably strengthen plantation density during field planting, plant about 1900 strains for general every mu, line-spacing is pressed 1.4 meters, 25 centimetres of spacing in the rows, strengthen management diligent spraying fertilizer, the ridging of weeding in time after the field planting, prevention waterlogging is preserved moisture, clear shaped branch is strengthened the extermination of disease and insect pest, for material base is laid in exploitation in the coming year.

3, field management.The asparagus field planting enters picking time in 1 year spring 4, May, and its management mainly is to strengthen the rich water quality management and the extermination of disease and insect pest.Water, soil moisture content can not be hanged down 16% and be stayed female footpath in good time: stay the method in female footpath to take to stay in 1 year foster twice female stem, after the beginning of spring, asparagus begins to take out living tender stem, can gather as green asparagus this moment to taking out living tender stem, and gathering begins to stay foster spring stubble to mid-May, and 2 years bamboo shoot fields can be stayed and support 3-4.It is foster to pay attention to staying of autumn stubble.Asparagus is gathered late August, owing to gather for a long time through aestivate, the stored nutrient of its root exhausts substantially, the tender stem that grows attenuates, and quality and yield obviously descends, the acrial part flavescence, should in time stop to gather this moment, does garden clearly well, enters autumn and stay foster management phase.

4, fertilising: twice fertilizer of annual heavy dressing.For the first time be spring tender stem take out before death vernalization fertilizer.The autumn that for the second time is early September is sent out rejuvenation fertilizer, and general each mu is executed barnyard manure 2000-3000kg, composite fertilizer 50kg.After entering picking time, in time topdress, topdressing repeatedly gently to execute is principle, topdresses for the first time when tender stem begins to extract out, adopts bamboo shoot early stages every 15-20 days, and fertilising is 1 time about 10 days later stages, every mu of sealing fertilizer 50kg or corresponding urea and phosphate fertilizer.5, the extermination of disease and insect pest: 1, do a good job of it the field health, reduce bacterium source base.The main disease of harm asparagus is a stem wilt, and insect pest is prodenia litura, blue or green worm etc.1 year twice clear garden thoroughly remove the field old and feeble withered old female stem and the residual leaf of deadwood, weeds, concentrate and burn, then with the sterilization that carries out disinfection of 600 times of liquid of asparagus green grass or young crops pulvis of 40%.2, spray method in the employing is strictly on guard against that disease takes place.When the spring autumn stubble stays and supports, when female stem grows to 5cm when high, luckyly win+80% with 50% pair, sprayed once in general 5-7 days, will fill spray behind the chance rain than the 500 times of liquid spray medicines of getting profit.3, pest control.Should get with agricultural measures for the bamboo shoot parasitosis and to prevent and treat.Based on biological control, take black old lamp trapping etc., spray chemical pesticide less as far as possible.
