Embodiment
Following embodiment is convenient to understand the present invention better, but does not limit the present invention.Experimental technique in following embodiment, if no special instructions, is conventional method.If no special instructions, " % " representation quality percentage.
Pleurotus ferulae soil covering culture method in winter concrete steps of the present invention are as follows: the requirement to booth in Pleurotus ferulae wall-in winter soil covering culture: in Edible Fungi booth, booth sits in the north facing the south, behind north, wall is thickness 120 centimetres, highly for 180-220 centimetre building cob wall or brickly to form, end face is steel frame construction, needs to cover horticultural covering film, straw screen or mat or cotton curtain so that Winter protection.Just Pleurotus ferulae wall-soil covering culture can be carried out when temperature is down to 6-15 DEG C when annual autumn.
1, the choosing and process of cover soil material: first select to fetch earth, requires to cut out sandy loam soil layer top layer, gets the soil on less than 20 centimetres, below top layer.Prepare Nutrition Soil, for Pleurotus ferulae bacterium bag earthing.Applied nutrition earth culture educates Pleurotus ferulae, can improve Pleurotus ferulae output, and each bacterium bag output reaches 400-600g; And directly apply sandy loam cultivation Pleurotus ferulae, each bacterium bag output is 200-300g.
In Nutrition Soil, the mass percentage of each component is as follows: sandy loam: 70%; The aqueous solution 30%.Sandy loam and aqueous solution is even, obtained Nutrition Soil.
Each component proportion in the aqueous solution: quicklime 2 kilograms, edible 0.5 kilogram, brown sugar, potassium dihydrogen phosphate 0.2 kilogram, 97.3 kilograms, clear water, Cobastab 10, its weight can be ignored.
2, the choosing and process of Pleurotus ferulae bacterium bag: Pleurotus ferulae bacterium bag is generally about 20-23 centimetre, require to choose Pleurotus ferulae bacterium bag cell age at about 4 months, mycelia is pure white dense strong, not have the bacterium bag of pollution.By the plastics girdling of bacterium bag by middle 4 centimetres, remove plastics, then sterilize in gram mould chloroazotic acid bacterium bag being soaked in 0.2%, within 10 minutes, pull that to dry surface water for subsequent use out.
3, earthing: according to the width of Pleurotus ferulae cultivation booth, determine bacterium wall length, bacterium wall is south-north direction, and general cut to lengthen is about 5-5.5 rice, and between bacterium wall, width is at 80 centimetres-100 centimetres.Long 5.5 meters of making ridge, wide 20 centimetres, high 5 centimetres on the ground, pounds into below ground 20 centimetres so that fixing bacterium wall at ridge two ends with the waddy of 80 centimeter length or reinforcing bar.Nutrition Soil is laid on ridge, the bacterium bag handled well one deck Nutrition Soil one deck bacterium bag code as the masonry walls of base is become bacterium wall, every layer of Nutrition Soil 2 centimetres, when code is to 5 floor height, extract two thin wires to be tightly connected on the fixed leg at bacterium wall two ends, be pressed in above bacterium wall, prevent bacterium wall from collapsing.Continuation code bacterium bag, best when floor height is 8 layers of Pleurotus ferulae, this height can prevent bacterium wall from collapsing, and is better beneficial to ventilation.Bacterium bag code is complete is covered with 4 centimetres of Nutrition Soils above again, is covered with 20 centimetres of broadly film or plastics moisturizings.
4, manage: after bacterium wall earthing, ceiling builds straw screen or mat, every day, booth ventilated twice, was no less than 30 minutes at every turn, controlled greenhouse temperature 8-12 DEG C, faint light scattered light 200lx-500lx, humid control, at 65%-75%, is regulated by these four kinds of physics, impels Pleurotus ferulae mycelia slowly to grow in Nutrition Soil, send out bacterium 20 days, treat that Pleurotus ferulae mycelia crawls into Nutrition Soil 2 cm and can carry out management of producing mushroom.Now regulate the booth temperature temperature difference by lifting ceiling straw screen or mat every day, daytime temperature controls at 18 DEG C, night 6 DEG C, humidity remains on 85%, strengthens light to 1000lx-1500lx, diligent ventilation, improve oxygen content, every day, each ventilation once, at every turn must not lower than 40 minutes sooner or later.Stimulated by the temperature difference, light, impel mycelia to twist together, because Pleurotus ferulae is aerobic mushroom, stronger ventilation, avoids misshapen mushroom.By the physical stimulation of about a week, the mycelia at bacterium bag two ends started kink, forms small mushroom bud, when small mushroom bud rises to thumb size, remove the more weak mushroom flower bud of figure with pocket knife, leave large, medium and small each healthy and strong mushroom flower bud, when Pleurotus ferulae grows to maturation, gradation is selected.When the Pleurotus ferulae of all maturations of booth is selected complete, cleaning bacterium bag two ends residue mushroom root, reduces booth humidity to 60%, reduces and ventilate, once a day, each half an hour, build straw screen or mat, and keep dark, temperature controls at 6 DEG C, carries out the 2nd management of producing mushroom after one month.Doubled than conventional fruiting output by Pleurotus ferulae soil covering culture.
