Step 2: seedling replanting:Taken out when the growth of seedling in blake bottle is to 4~5cm, first clean seedling root with clear water The culture medium in portion, then diluted immersion root with 0.1% potassium permanganate and sterilized, is transplanted to greenhouse with 3 plants one clump, with the cm of 20cm × 20 Distance between rows and hills be colonized, greenhouse has the matrix in fly net cladding, greenhouse by bark sawdust into bits, and is poured by boiling water and boil 60 ~90min, is dried and forms, and ventilation unit and heating plant are provided with greenhouse;
Step 3: moisture and moisture management:Seedling after to just transplanting carries out spraying and watered, and the pH value of water is controlled 5.5 ~7.0, the water content for controlling matrix is 60~70%, and hand, which grabs matrix, to be had wet sense but do not drip, after transplanting in 7 days, the sky in greenhouse Air humidity degree is maintained at 90% or so, and after transplanting 7 days, 70~80% are maintained at when seedling grows the air humidity in new root, greenhouse;
Step 4: temperature and illumination management:It is 20~25 DEG C to control the temperature in greenhouse, during summer high temperature, on greenhouse It is 70~75% sunshade nets to cover individual layer black sunshade degree, and strengthens ventilation and heat, and spraying dissipates temperature, during winter low temperature, and greenhouse is used Sunshade degree be 30~50% Shading net covering, and with double-plastic close be incubated, it is ensured that effective accumulated temperature 5000 DEG C with On;
Step 5: fertilizing management:Seedling replanting sprays solution after 2 weeks, spray once within every 2 weeks, and disleaf is gone in watering after spraying Solution on face, every year respectively in March, September organic fertilizer 1 time;
Step 6: the prevention and control of plant diseases, pest control:Monthly sprayed with 800~1000 times of liquid of equivalent formula Bordeaux mixture and carry out foliar control, Insect prevention uses fly net.
Preferably, 25 DEG C~28 DEG C of the cultivation temperature, daily illumination 9~10 hours, intensity of illumination is 160~180 μ mol.m-2.s-1
Preferably, the stromal thickness in the step 2 in greenhouse is 8~12cm.
Preferably, the raw material of solution is made up of Zn-ef ficiency in the step 5, using when Zn-ef ficiency:Pure water is with 1: 1000 dilution proportion is simultaneously sprayed after stirring.
Beneficial effects of the present invention:Compared with prior art, a kind of raising dendrobium candidum Zn-ef ficiency that the present invention is provided The factor such as the content of Zn-ef ficiency and effective accumulated temperature, illumination is related in cultural method, simple and reasonable steps, dendrobium candidum, with having Increase, the illumination for imitating accumulated temperature are sufficient, and Zn-ef ficiency content increases therewith in dendrobium candidum, and moisture is carried out to greenhouse by Various Seasonal With humidity, temperature and the management of illumination, the temperature control in greenhouse in control greenhouse at 20~25 DEG C, the temperature difference within 5 DEG C, There is provided good growing environment, while ensuring effective accumulated temperature more than 5000 DEG C, it is ensured that effective accumulated temperature is sufficient, is conducive to nutrition Material is transported and accumulated to cane, is improved the generation of Zn-ef ficiency in dendrobium candidum, is promoted the medical value of dendrobium candidum.
The feature and advantage of the present invention will be described in detail by embodiment.
Embodiment
To make the object, technical solutions and advantages of the present invention of greater clarity, below by embodiment, the present invention is entered Row is further described.However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention, and without In limitation the scope of the present invention.In addition, in the following description, eliminate the description to known features and technology, so that avoid need not Obscure idea of the invention in strategic point.
The embodiment of the present invention provides a kind of cultural method for improving dendrobium candidum Zn-ef ficiency, comprises the following steps:
Step 1: seedling breeds:The dendrobium candidum seedling of wild growth is chosen, explant culture is carried out, turns out flower After bud or leaf bud, culture medium is prepared, and bud or leaf bud are put into progress sterile propagation culture in culture medium, when growth of seedling is arrived During 1~2cm, it is dispensed into blake bottle and is cultivated, 30~45 plants of seedling is cultivated in each blake bottle;
Step 2: seedling replanting:Taken out when the growth of seedling in blake bottle is to 4~5cm, first clean seedling root with clear water The culture medium in portion, then diluted immersion root with 0.1% potassium permanganate and sterilized, is transplanted to greenhouse with 3 plants one clump, with the cm of 20cm × 20 Distance between rows and hills be colonized, greenhouse has the matrix in fly net cladding, greenhouse by bark sawdust into bits, and is poured by boiling water and boil 60 ~90min, is dried and forms, and ventilation unit and heating plant are provided with greenhouse;
Step 3: moisture and moisture management:Seedling after to just transplanting carries out spraying and watered, and the pH value of water is controlled 5.5 ~7.0, the water content for controlling matrix is 60~70%, and hand, which grabs matrix, to be had wet sense but do not drip, after transplanting in 7 days, the sky in greenhouse Air humidity degree is maintained at 90% or so, and after transplanting 7 days, 70~80% are maintained at when seedling grows the air humidity in new root, greenhouse;
Step 4: temperature and illumination management:It is 20~25 DEG C to control the temperature in greenhouse, during summer high temperature, on greenhouse It is 70~75% sunshade nets to cover individual layer black sunshade degree, and strengthens ventilation and heat, and spraying dissipates temperature, during winter low temperature, and greenhouse is used Sunshade degree be 30~50% Shading net covering, and with double-plastic close be incubated, it is ensured that effective accumulated temperature 5000 DEG C with On;
Step 5: fertilizing management:Seedling replanting sprays solution after 2 weeks, spray once within every 2 weeks, and disleaf is gone in watering after spraying Solution on face, every year respectively in March, September organic fertilizer 1 time;
