Abstract
The invention discloses a propagation method of dendrobium candidum seeds. The method comprises the following steps: in winter, firstly mature dendrobium candidum seeds are harvested and dried so as to be subjected to safe hibernation; a shade net covers a sowing greenhouse, so that the sowed seeds are free from the influence of rain wash and wind, and normal air circulation can be kept; the disinfection and germicidal treatment is performed to sawdust and peanut shells as the cultivation base; after cold weather of the spring is over, the seeds are sowed in a sowing bed; 85-90 percent of humidity of the sawdust is kept; and after a large proportion of sowed seeds are germinated, the temperature is strictly controlled not to exceed 35 DEG C, and meanwhile organic fertilizer is applied. The method can improve germination percentage of dendrobium candidum breeding and planting livability of transplanting; through adopting the method, the lowest germination percentage of the dendrobium candidum seeds is about 40 percent, and the highest germination percentage is about 60 percent, and the average germination percentage is about 45 percent; and transplanting livability reaches over 98 percent. The method of the invention is simple in operation, is low in cost, and is environment-friendly.
Description
Technical field
The present invention relates to a kind of seed propagation method, be specifically related to a kind of propagation method of dendrobium candidum seed.
Background technology
Dendrobium candidum is listed in " first of the Chinese nine immortal grass ", since the Tang and Song Dynasty, has been listed in royal tribute always.Li Shizhen (1518-1593 A.D.) is estimated dendrobium candidum " reinforcing yin essence benefit is smart, and thick stomach is never sufficient in the benefit, flat stomach Qi, longue meat, intelligence development is made light of one's life by commiting suicide and prolonged life except frightened " in Compendium of Material Medica; Among the people being called " the celestial grass of help ".In addition, the stem of dendrobium candidum can clearing heat and promoting fluid, anti-inflammatory analgetic, and clear and rich throat has a better curative effect to the treatment voice is hoarse.
Dendrobium candidum generally is grown between the height above sea level 100-3000 rice height, often grows nonparasitically upon another plant in setting upward or on the rock, liking warm, moistening and half cloudy environment, and is cold-resistant.18～30 ℃ of growth thermophilics, vegetative period is more suitable with 16～21 ℃, and 16～18 ℃ of resting stages, evening temperature is 10～13 ℃, and the temperature difference remains on 10～15 ℃ of the bests.Day temperature is little to stem of noble dendrobium growth effect above 30 ℃, and winter temperature is not less than 10 ℃.Seedling is being endured cold below 10 ℃ easily, and is harsh to the environmental condition requirement of growth.Low, the poor growth of natural propagation ability of wild dendrobium candidum.And at present in dendrobium candidum biological engineering process, the seed germination rate is less than 20% often, and the survival rate after the transplanting is also less than 60%.This has greatly limited the cultivation of dendrobium candidum.
Summary of the invention
The objective of the invention is to solve above-mentioned the deficiencies in the prior art, a kind of propagation method that can improve dendrobium candidum breeding germination rate and transplant the dendrobium candidum seed of plantation survival rate is provided, the seed germination rate minimum about 40% when using this method, Gao Yueda 60%, about average out to 45%, and the transplanting survival rate has increased substantially economic benefit up to more than 98%.
For achieving the above object, the present invention is by the following technical solutions:
A kind of propagation method of dendrobium candidum seed may further comprise the steps:
1, in the winter time, earlier the dendrobium candidum seed collection after the maturation and dry, be put in the cool place, dry ventilation is preserved, prevent moldy metamorphism and can safe hibernation.
2, cover the nylon matter shade net that screening sunshade degree reaches 75-90% on the sowing booth, isolate with film all around, the seed bed height overhead can not make it after planting avoid rain drop erosion and windage less than 30cm, can keep air normally to circulate again.
3, cultivate the sill chaff, peanut shell is handled with sterilization drugs, preferably carries out high-temperature sterilization, service property (quality) concentration is that 0.1% potassium permanganate boiling water sprays during sterilization, reaches more than 80 ℃ till back 5 minutes to cultivating Ji Wendu.
4, the peanut shell of handling well is layered on to do on the seed bed of backing with linoleum cloth does the plantation bottom, thick about 5cm, particle diameter 0.5～0.8cm; Repave wooden chaff (be preferably weedtree, as Qinggang wood, black rice wood, escape army provisions, Door frame etc.) and cover and do the plantation top layer, thick about 1～2cm, particle diameter 0.1～0.2cm, and it is flattened.
5, be selected in Clear and Bright after the severe cold to season in grain rains in spring, earlier the seed bed of completing sprayed water with atomizer, make it fully drenched, again seed is sowed on the seed bed.
6, after seed was broadcast, key was to control moisture content and humidity, made wooden chaff should keep certain humidity, but moisture content again can not be too many, and humidity is with 85-90% the best.And because the seed of dendrobium candidum is very little, required moisture content will prevent from seed is washed out through spray again after the atomizing.
7, through a wheat harvesting period, after the most of germination of seed, strict temperature control, can not surpass 35 ℃, be preferably between 20-28 ℃, spray thin fertilizer (organic fertile) simultaneously, its mass concentration can not surpass thousand/3-5, avoids burning seedling, sprays frequency and sprays once with about ten days and get final product.
8, because the seed of dendrobium candidum is very responsive to medicine, and ordinary circumstance is not wanted random dispenser, bactericide is used methyl Tobe zinc, fenaminosulf always; Insecticide is commonly used auspiciously attacks, sharp Qiong Te, its mass concentration can not surpass 5/1000ths, and this concentration can't be killed some insect, so also want frequent indirect labor to catch and kill, insecticide sprayed with about 30 days and once gets final product, and bactericide then sprayed with about 15 days once is advisable.
Advantage of the present invention is: the seed germination rate is minimum about 40%, Gao Yueda 60%, and average out to about 45%, and the transplanting survival rate has increased substantially economic benefit up to more than 98%.
