Specific embodiment
Embodiment 1
1. seed collection and preservation
When month last year 11-12, fruit was fully ripe, collecting fruit.Now, part capsule natural cracking, seed is in light
Yellow, dust-like.After collecting fruit, fruit one end is cut off with scissors, seed is scattered, room ventilation is collected and be stored in newspaper
Place, it is standby.
2. the preparation in place is bred
The natural environmental condition of the suitable Growth of Dendrobium candidum of selection, height above sea level 600-1000 meters, more than 0 DEG C of annual minimum temperature,
Humidity more than 60%, light application time is long, and water resource is enriched in region, can meet irrigation needs.
Greenhouse construction is circular arc vault stalk formula, and canopy wide 8 meters rises 4.8 meters, and it is bone that greenhouse uses light-duty galvanizing section bar
Frame, gravity-flow ventilation form.Set with sprinkling irrigation, every greenhouse hogging top lee face in sunshade net, greenhouse inside and outside plastic foil, 75%
Wound membrane opens a window, 1 road of side wall wound membrane windowing.
Liftoff 50-70 centimetres is built built on stilts seedbed, and bedside 1-1.4 meters, bed length is less than 40 meters, with plastics plain net, plank
Deng poromeric material as base plate.
3. matrix prepares
Fresh wood shavings and sawdust are collected in first 2 months i.e. January December to next year of sowing, wood shavings are laid on 5-7 lis of lower floor
Rice is thick, and sawdust is laid on 2-3 centimetres of upper strata, is then irrigated with water.Meanwhile, it is watered 30 jin of water by 1 jin of cow dung and dilutes, the ox that will be diluted
Liquid manure body is uniformly spread on bed surface.After a dry tack free once after, then pour permeable, afterwards, spray the nutrient solution of MS desaccharification formulas
Once, bed surface moistening and is unanimously kept.Through watering after a while, matrix has certain hardened degree, and seed is big when can prevent from sowing
Amount is lost in.
4. sow
