Abstract

The invention discloses a fir cuttage method of dendrobium candidum. The fir cuttage method comprises the following steps: building three fir logs by using a special dendrobium candidum planting support; fixedly planting a tissue culture seedling between two firs, and keeping roots of the seedling exposed; culturing the dendrobium candidum tissue culture seedling on the support. The seedling can be watered at any time by spraying, and excessive water can be drained at any time, so that root rotting and seedling death caused by too much water are avoided, ventilation and free breath of a root system can be ensured, and thus the transplanting survival rate is greatly improved and can be above 95%; plant diseases and insect pests are effectively controlled, the seedling is strong, the root system is developed, and the quality is good.

Description

A kind of dendrobium candidum China fir cottage breeding method

Technical field

The present invention relates to agriculture cottage breeding technology, particularly relate to a kind of dendrobium candidum China fir cottage breeding method.

Background technology

The place of dendrobium candidum plantation or carrier, can select level land, hillside, body of wall, crag, trunk, balcony, flowerpot, requires not ponding, easily drainage.During cultivating and growing, can the cultivation matrix of 3 ~ 5 centimetres on first place mat, then as seedling of planting trees, the seedling cleaned is planted in matrix and go.

The seedling that the multiplex plantlet in vitro of the stem of noble dendrobium and biennial stem section bring out is planted.The seedling of firm plantation will shelter from heat or light, high humidity, but can not waterflooding.Plantlet in vitro will first carry out seedling transition can move into field production, and transition matrix can select humus or perlite, sprays foliage fertilizer one to twice weekly.The plantlet in vitro refined or the cuttage seeding of taking root can be planted in Yushan Hill on large tree, and on the tree of some thicker barks, longitudinal furrow place plants seedling, just tie up can, and seedling is by the moisture content in absorption bark and nourish and grow, and also can add humus soil with rubble and add liver moss again, cloudy canopy on tower.

The propagation method of conventional dendrobe tissue culture seedling, the weak point of existence is: plantlet in vitro survival rate is low, and rhizome is thin, and general survival rate is 50-60%, and damage by disease and insect is many, management inconvenience.

A kind of dendrobium candidum China fir of the present invention cottage breeding method, utilize dendrobe cultivation special stand, set up three China fir logs, by plantlet in vitro fixation in the middle of two China firs, keep the root of seedling exposed, no pesticide grown in cultivation, at cultured on scaffolds candidum tissue culturing seedling, can spray at any time and water, drain excessive moisture at any time, can not cause rotten dead seedling because moisture is too many, and can ensure that root system is ventilated, thus transplanting survival rate improves greatly, can more than 95% be reached, Miao Zhuan, well developed root system, superior in quality.

The invention provides a kind of dendrobium candidum China fir cottage breeding method, improve the yield and quality of the stem of noble dendrobium, shorten stem of noble dendrobium growth cycle, key effect is got to the improvement of stem of noble dendrobium new varieties.

Summary of the invention

A kind of dendrobium candidum China fir cottage breeding method, is characterized in that: adopt nursery special stand, cottage breeding technology, described dendrobium candidum China fir cottage breeding method comprises the following steps:

Select attached master: set up stem of noble dendrobium training seedling special stand, comprise support column, tail trimmer, long beam, curb girder.It is characterized in that: two support column racking seizings are fixed, vertical colligation two crossbeams on brace summer, the angle of two support columns is 40--60 °, and the interval of two support column crosspoints and two crossbeams is respectively 50cm.Support and support parallel laid, stacking three curb girders in crossing of the support column of two supports, the two ends of tail trimmer are stacking three curb girders respectively, two ends stacking three curb girders respectively of long beam, and three curb girder two ends respectively colligation are fixed;

Size according to place lays support successively;

Two China fir logs that support column is 2 meters by length intersect and form;

Support as above high 1.5 meters, the angle of two brace summers is 40--60 °;

The interval of support crosspoint as above and two crossbeams is respectively 50cm;

Support as above, China fir log bore 5-10cm.

Breed:

Employing plant division is bred.Select life in 1 year or life in 2 years, color and luster is light green, sprouting is many, well developed root system, do kind of a strain without the plant of damage by disease and insect, cut off long fibrous root, cut by strain clump, be divided into little Cong, every clump has 5 ~ 7 to be with base of leaf strain;

The band base of leaf strain chosen inserted in the middle of two stacking China firs, at curb girder both sides spacing 3cm interdigitation, the root of stem strain is in atmosphere exposed, no pesticide grown in cultivation.

Field management:

(1), prune: when annual spring germinates or the time of gathering, cut off the old branch of part or deadwood, and grow overstocked stem branch, promote that sprouting grows;

(2) turn over pocket: carry out turning over pocket according to growing state, remove withered, old root, carry out plant division, cultivate separately, promote plantation growth.

The extermination of disease and insect pest:

Common insect pests is snail, and it endangers young stem, tender leaf, bud and young fruit, adopts manual catching and killing, period poison bait or the control that limes.
