Description
Technical field
The present invention relates to plant cultivation technologies in gardening, and in particular to paulownia bury root container seedling culture method.
Background technique
Paulownia (Latin literary fame: Paulownia.), alias: fortune paulownia, big fruit paulownia, Kongtong wood etc..Bark grey, ash
Brown or grey black, smooth when young, lobe when old.False two wooden fork branches.Dan Ye, to life, Ye great is oval, and full edge or have shallowly is split, and has
Long handle, villous on handle.Light, it is more shade tolerant, temperature climate is liked, cold resistance is not strong.The tree species of Paulownia are all native to China
, it is introduced a fine variety very early to Vietnam, Japan and Asia various regions.It has been distributed to the whole world at present.
The country buries that root nursery research report is less, and existing paulownia bury root seedling raise period generally at spring 2 months to 3 about paulownia
Month, nursery lot making ridge, after kind of root is carried out in certain distance on ridge uprightly to bury root, water drenching moisturizing, to height of seedling 10cm into
The nursery stock of seedling in the ranks, top dressing, the afforestation that is out of the garden is bare-root seeding, easily causes to damage to root system when being out of the garden, influences the surrival rate of afforestation, is afforested
Growth recovery is slow afterwards.When carrying out nursery by this technology, Seedling bag is transplanted to after cultivating root, budding with nursery support, cultivation is arrived
Proper height can be out of the garden.The less of container nursery appears in the newspapers, and buries root nursery, the selection of the type of rearing of root and matrix is to bubble
The influences such as the quality of the survival rate for burying root container nursery of paulownia, nursery stock rate and nursery stock are very big.
Summary of the invention
The purpose of the present invention is overcoming the deficiencies of the prior art and provide paulownia to bury root container seedling culture method, including paulownia are buried
Seedling medium used in root nursery, container for plant growth, method for culturing seedlings etc..
Paulownia bury root container seedling culture method, include the following steps:
1) the kind root of paulownia being cut into the segment that length is 5-6cm, be embedded in nursery support, 45 degree of Zhong Gencheng are neatly put,
Divide good pole up and down, filled with matrix, retains 1cm and expose matrix, water of drenching after burying keeps the humidity of matrix；
2) take root after budding, the kind root for choosing the high 3cm of bud is transplanted, and when transplanting, carefully digs out kind of a root, avoid root system by
Wound retains advantage bud when kind and erases other budlets, and plant is educated in bag in plastics, root water of drenching after transplanting；
3) shaded with 75% sunshade net, shading opens black net and carries out full photonursery stock growing after 7 days, daily water drenching is protected
It is wet, it applies fertilizer based on phosphorus potash fertilizer, after cultivating 2 months, height of seedling reaches 30cm, that is, be out of the garden afforestation.
The kind root of paulownia is preferably cut into the segment that length is 5-6cm, is embedded in nursery support by step 1) of the present invention
In, kind of root 70 are often propped up, 45 degree of Zhong Gencheng are neatly put, and divide good pole up and down, is filled with matrix, matrix is peat soil: coco bran:
Carbonized rice husks=3:3:4 (volume ratio) retain 1cm and expose matrix, and water of drenching after burying keeps the humidity of matrix.
The step 2), when referring to 25 DEG C of temperature degree, 1 week starts root out, begins with bud within 15 days and grows, 20 days kind roots
Go out root rate up to bud ratio after 90%, 30 day up to 80%, the kind root for choosing the high 3cm of bud is transplanted, and when transplanting, carefully uses bamboo pole
Kind of a root is dug out, avoids root system injured, when kind retains advantage bud and erases other budlets, and the plastics planted in 12 × 15cm are educated in bag, educated
Seedling matrix is peat soil: coco bran: carbonized rice husks=3:3:4 (volume ratio), root water of drenching after transplanting.
The step 3) refers to and is shaded with 75% sunshade net that shading is opened black net progress full exposure and educated after 7 days
Seedling, daily water drenching moisturizing, paulownia growth is very fast, and fertilizer requirement is less, applies fertilizer based on phosphorus potash fertilizer, at 10 centimetres of height of seedling, applies 0.3%
Phosphorus potash fertilizer, apply and impose 0.3% compound fertilizer after phosphorus potash fertilizer twice again, fertilising in every 10 days is primary, after cultivating 2 months, height of seedling
Up to 30cm, that is, be out of the garden afforestation.
Compared to the prior art, the present invention has the advantage that
1, the time of nursery is short, only needs 2 months.
2, survival rate of seedling is high, and up to 98%, seedling quality is good.
3, nursery place is saved, method for culturing seedlings is simple and practical.
4, the present invention is had found by a large amount of comparative experiments, and kind of root is cut into the segment that length is 5-6cm,
Such kind of root utilization rate is high, and high survival rate, kind root is too short, and survival rate reduces, and kind root is too long, is unfavorable for planting, and
Waste kind root.
5, fertilization mode during cultivating seedlings, the degree of lignification of nursery stock can be enhanced and increase the anti-of nursery stock by applying phosphorus potash fertilizer
Characteristic of disease makes the survival rate of wood conducive to nursery stock.
6, container nursery, when being out of the garden, seedling root saves complete, high survival rate after afforestation.
Specific embodiment:
With embodiment, the invention will be further described below, but the invention is not limited to these embodiments.
Embodiment:
Paulownia bury root container seedling culture method, include the following steps:
1) the kind root of paulownia is cut into the segment that length is 5-6cm, be embedded in nursery support, often prop up kind of root 70, plant root
It is neatly put in 45 degree, divides good pole up and down, filled with matrix, matrix is peat soil: coco bran: carbonized rice husks=3:3:4 (volume
Than), retain 1cm and expose matrix, water of drenching after burying keeps the humidity of matrix；
2) 25 DEG C of temperature degree when, 1 week starts root out, begins with bud within 15 days and grows, and 20 days kind roots go out root rate up to 90%,
Bud ratio up to 80%, transplanted by the kind root for choosing the high 3cm of bud after 30 days, when transplanting, is carefully dug out kind of a root with bamboo pole, is avoided root
System is injured, and when kind retains advantage bud and erases other budlets, and the plastics planted in 12 × 15cm are educated in bag, and seedling medium is peat soil:
Coco bran: carbonized rice husks=3:3:4 (volume ratio), root water of drenching after transplanting；
3) shaded with 75% sunshade net, shading opens black net and carries out full photonursery stock growing after 7 days, daily water drenching is protected
Wet, paulownia growth is very fast, and fertilizer requirement is less, applies fertilizer based on phosphorus potash fertilizer, at 10 centimetres of height of seedling, applies 0.3% phosphorus potash fertilizer, applies two
0.3% compound fertilizer is imposed after secondary phosphorus potash fertilizer again, fertilising in every 10 days is primary, and after cultivating 2 months, height of seedling reaches 30cm, that is, is out of the garden
Afforestation.
Seedling raise period: April in January-, 23 DEG C of samming of day, illuminance 2000LUX.
The paulownia kind root nursery carried out is compareed with currently available technology using above-described embodiment, it can from the result of following table
Out, the invention has the advantages that
