Description

A kind of implantation methods of camellia
Technical field
The present invention relates to a kind of method for cultivating seedlings, belongs to camellia field of planting, more particularly, it relates to a kind of The implantation methods of camellia.
Background technology
Camellia also known as camellia, it is the common name of Theaceae, Camellia various plants and garden-variety.Petal is bowl-type, point Single-lobe or polyphyll, single-lobe camellia are mostly original seed, and the petal of polyphyll camellia can up to 60.Camellia have it is different degrees of it is red, Purple, white, the yellow assorted seeds of flowering plants, or even chromatic colour speckle camellia is gone back, and spray highest can reach 4 meters.Property happiness it is warm, moistening ring Border.Florescence is longer, has opening from May in October to next year, full-bloom stage is generally in 1-3 months.
Because its plant shape appearance is graceful, leaf to be dark green green and gloss, flower-shape are gorgeous in riotous profusion, and by the treasure of world's gardening circle Depending on.The kind of camellia is extremely more, is the ornamental flower of Chinese tradition, ranking the 8th in " ten big famous flowers ", is also world's famous flower and tree One of.
And the Cultivating techniques of camellia are mainly two methods of grafting and cuttage in the prior art, such Cultivating techniques by The influence of the environmental factors such as certain season, temperature, camellia survival rate is low, can not meet the needs of camellia plantation;Therefore, we Need to propose the type of rearing that a kind of camellia survival rate is high, improve and cultivate efficiency, meet the needs of camellia plantation.
The content of the invention
Based on above technical problem, the invention provides a kind of implantation methods of camellia, so as to solve conventional camellia into The low technical problem of motility rate.
To solve above technical problem, the technical solution adopted by the present invention is as follows:
A kind of implantation methods of camellia, comprise the following steps:
1) nursery lot selects:Selection is had abundant water resources, and physical features is flat open, and the soil is porous, and drainage condition is good, and P in soil H is in 5- 6.5 hillside fields;
2) nursery lot arranges:The soil in hillside fields is deep ploughed, applied fertilizer in bottom, earthing treats soil-ripening for 3 days, then table soil is buried Go down, flatten, management in idle time 10-15 days;
3) whole furrow:Soil after would sit idle for carries out whole furrow, the wide 40-60cm of furrow, is digged pit on furrow, cheats deep 15-25cm;
4) camellia seedling selects:Choose well developed root system, robust growth, the healthy camellia seedling of no disease and pests harm;
5) transplant:The camellia seedling chosen is put into hole, makes in order and unfolds root system, nursery stock is gently carried upwards after inserting fine earth, Banket and be compacted again, field planting of being watered after the completion of banketing;
6) prune:
A, treelet:A small amount of trimming, the extension branch in center and each major branch, accessory branch are extended branch and carry out moderate or severe cutting back;
B, bearing tree:Branch group, decline branch group are truncated, and wipes out the branch that is in the light, deadwood, sick branch;
7) apply fertilizer:Using the fertilizing method of bar ditch spread;
A, treelet:The hair phase is taken out in spring, summer, autumn treetop to apply fertilizer 3-4 times;
B, bearing tree:Apply rudiment fertilizer in four times;
On the basis of above technical scheme:Mainly based on nitrogenous fertilizer, compounding application phosphate fertilizer, potash fertilizer are single for the treelet fertilising Strain seedling nitrogen fertilizer application 0.2-0.5kg;The dose of bearing tree:Rudiment fertilizer adds a load liquid dung for 3-4 jin chemical fertilizer.
On the basis of above technical scheme:The camellia implantation time is annual late fall.
On the basis of above technical scheme:A digging fertilizers into fields is carried out to soil where camellia tree at interval of 1 year.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows:Camellia plants skill in the present invention Art is simple, and the survival rate of camellia is high.
