Description

Method for growing outdoor asparagus seedlings in summer

One, technical field:

The present invention relates to a kind of asparagus seedling-cultivating method, particularly a kind of method for growing outdoor asparagus seedlings in summer.

Two, background technology:

Good and bad its cultivation and the output of directly influencing of asparagus kind, therefore, the plantation asparagus must remove to select for use the improved seeds that output height, quality are good, adapt to local condition according to development plan (white bamboo shoot or green bamboo shoot), the improved seeds of relatively more suitable coastal saline-alkali area plantation have: the development white asparagus can be selected Mary Washington 500W, Shandong asparagus for use No. one, and green asparagus is selected UC800, Shandong asparagus for use No. one.But, except the asparagus breed selection, also needing correct seedling-cultivating method, existing seedling-cultivating method is grown seedlings summer, and arid is hindered bud, waterlogging caused by excessive rain decreases seedling, causes the not high problem of survival rate.

Three, summary of the invention:

Purpose of the present invention is exactly the above-mentioned defective that exists at prior art, and a kind of method for growing outdoor asparagus seedlings in summer that improves the asparagus survival rate is provided.

Its technical scheme is: be made up of following steps:

(1) choosing ground: will select fertile soil (about the content of organic matter 1%), the soil is porous with growing seedlings, and air capacity of soils is strong, the loam or the sandy loam of saline and alkaline light (total salt content is below 0.15%); Require physical features higher with growing seedlings, unsuitable ponding, irrigation and drainage are convenient, and pumping equipment will be improved in the large tracts of land field of growing seedlings;

(2) wholely: after the plot was chosen, it was clean with hoes such as weeds, wheat stubbles to move ahead, and cleaned out extraterrestrially, executed high-quality farmyard manure 3500-5000 kilogram for every mu, 10 kilograms of composite fertilizers deep plough 30-40 centimetre, and furrow, furrow 1.2-1.5 rice are done in leveling then, reserve an amount of overburden soil, leveling furrow face is prepared sowing;

(3) presoaking and germinating: at first seed is immersed in the clear water, float not plump kind, broken cur and foreign material etc., the seed of coated processing is directly with the emerge in worm water of 35-45 degree 12 hours; Without the seed of Cotton seeds, then soaked 6 hours with 300 times of liquid of 50% carbendazim, after the sterilization, use 40 ℃ of emerge in worm water 12 hours again; After the abundant imbibition of seed, leach, be placed in square position or the dish, the wet cloth of loam cake carries out vernalization, during every day eluriate once with clear water, and change wet drop cloth, when seed has radicle about 10-15% to show money or valuables one carries unintentionally, can sow.

The invention has the beneficial effects as follows: overcome the arid of growing seedlings summer and hindered the difficulty that bud, waterlogging caused by excessive rain decrease seedling, realized growing seedlings summer and cultivated anosis survival rate in the strong sprout target more than 95%.

Four, embodiment:

May further comprise the steps:

(1) preferred kind: good and bad its cultivation and the output of directly influencing of asparagus kind.Therefore, the plantation asparagus must remove to select for use the improved seeds that output height, quality are good, adapt to local condition according to development plan (white bamboo shoot or green bamboo shoot).The improved seeds of relatively more suitable coastal saline-alkali area plantation have: the development white asparagus can be selected Mary Washington 500W, Shandong asparagus for use No. one, and green asparagus is selected UC800, Shandong asparagus for use No. one.

(2) put in order to choosing ground: 1. select ground: will select fertile soil (about the content of organic matter 1%), the soil is porous with growing seedlings, and air capacity of soils is strong, the loam or the sandy loam of saline and alkaline light (total salt content is below 0.15%); Require physical features higher with growing seedlings, unsuitable ponding, irrigation and drainage are convenient, and pumping equipment will be improved in the large tracts of land field of growing seedlings; In addition, to select from the village with growing seedlings nearer, or from field planting ground nearer plot so that management and balled transplanting.Preceding stubble grows seedlings ground for plot such as orchard, trees, shallot, garlic should not be elected to be.2. whole ground: after the plot was chosen, it was clean with hoes such as weeds, wheat stubbles to move ahead, and cleaned out extraterrestrially, executed high-quality farmyard manure 3500-5000 kilogram for every mu, 10 kilograms of composite fertilizers deep plough 30-40 centimetre, and furrow, furrow 1.2-1.5 rice are done in leveling then, reserve an amount of overburden soil, leveling furrow face is prepared sowing.

(3) presoaking and germinating: 1. seed soaking: at first seed is immersed in the clear water, float not plump kind, broken cur and foreign material etc., the seed of coated processing is directly used 40 ℃ of left and right sides emerge in worm water 12 hours; Without the seed of Cotton seeds, then soaked 6 hours with 300 times of liquid of 50% carbendazim, after the sterilization, use 40 ℃ of emerge in worm water 12 hours again, interchangeable water of seed soaking phase 1 time.2. after the abundant imbibition of seed, leach, be placed in square position or the dish, the wet cloth of loam cake carries out vernalization, during every day eluriate once with clear water, and change wet drop cloth, when seed has radicle about 10-15% to show money or valuables one carries unintentionally, can sow.

(4) meticulous sowing: 1. time: this advanced to arrive as yet rainy season or just began, and temperature is suitable, when temperature surpasses 32 ℃, influences the germination and emergence rate to early July late June.Therefore, to race against time after the wheat harvest, promptly seeding and seedling raising.2. soil moisture content: if soil moisture content is better behind the rain, the sowing of can losing no time in sowing while there is sufficient moisture in the soil if soil moisture content is bad, sowing the previous day is irritated vola water in the furrow that can put in order, requires to water foot and irrigates, and water quality is Huanghe water or fresh groundwater.3. sowing and transplant clever mixture and use is made the simple ditch instrument of drawing by line-spacing 10-20cm, and instrument is drawn good tool, drawn seed furrow with this instrument, ditch depth 1-2cm sprays seed furrow with transplanting clever mixture 300-400 times of liquid, 0.5 kilogram of mu dosage, to urge the seed simple grain program request of bud in ditch by spacing in the rows 5-10cm then, even again earthing, it is thin that earthing will be clapped broken sieve, and thickness is even, thickness 1-2cm, unsuitable blocked up.4. summer temperature is higher, the easy dehydration drying in seedbed, if before the bamboo shoot seedling was unearthed, bed surface high temperature and drought seriously overslaugh came up, influence emergence rate and strong sprout rate.Therefore, when arid appearred in bed surface, available sprayer evenly sprayed clear water, both can lower the temperature, again can humidification, or after finishing earthing, cover wheat bran, wheat flesh, leaf etc. and shade.5. insect protected: for preventing the harm of soil insect, behind the sowing earthing, mix 7.5 kilograms of thin dry ground, or 100 restrain that 0.1 kilogram of parathion-methyls or 80% ddvp emulsion is mixed 3 kilograms of not plump paddy or careless chaff is made poison bait, spread fertilizer over the fields on the furrow face with 0.5 kilogram of carbofuran Granules.

(5) seedling management: grow seedlings summer, and temperature height, high humidity, careless seedling are with giving birth to, grow rapidly, and weeds harm is serious, and therefore, in time weed out the rank grass prevents that striving water with asparagus strives fertilizer, and after seedling all sprouted, as finding aphid, available dimethoate emulsion was prevented and treated.The second terrestrial stem can impose 10-15 kilogram composite fertilizer after extracting out, waters immediately after the fertilising, to improve fertilizer efficiency.

(6) full range sterilizing: in seedling raising process, each link that may cause disease is all sprayed the medicine sterilizing, guarantees the healthy and strong growth of seedling.1. broadcast preceding soil disinfection: before the sowing, evenly spray 600 times of liquid of 75% tpn, carry out soil disinfection at whole good furrow face.2. seed disinfection: after seed soaking finished, with 300 times of liquid even spraying sterilizations of 40% carbendazim, it was susceptible to stop seed-borne fungi.3. sterilization in seedling stage: before coming up, evenly spray face with 600 times of liquid of 50% fenaminosulf.4. diseases prevention in seedling stage: emerge back spray in every 7-9 days medicine once, connect and spray 4-6, begin to reduce up to temperature, medication mainly contains the special 800 times of liquid of benzene Lay, 600 times of liquid of 1: 1 carbendazim+mancozeb, and 800 times of liquid of tpn, various medicines are used alternatingly, to strengthen drug effect.
