Abstract

A cuttage and breeding method for sabina vulgalis comprises the steps of renovating a cuttage bed, picking branches, processing shoot for cutting, performing cuttage and the like; deeply ploughing a seedling tray, clearing off impurities, applying cottage, leveling, widening to make a lower bed, and paving clean river sand on the seedling bed; sterilizing the sand bed which is 5-10cm thick with 800-1000 times of carbendazol liquid medicine; picking 1-2 years old healthy and strong branches without diseases or pests at dawn, putting the branches cut down in a plastic cask constraining water timely to prevent drying-up due to water loss; processing shoot for cutting by adopting different medicines and plant growing hormone with concentration being 50-150ppm for dipping for 2-6h, so that breeding coefficient is higher. Facts prove that the cuttage and breeding survival rate of sabina vulgalis bred by using the invention can reach up to 75-89%, thus realizing the aim of enhancing breeding coefficient.

Description

Cuttage and breeding method for sabina vulgalis

Technical field

The present invention relates to a kind of seedling-cultivating method, relate in particular to a kind of taking root property of difficulty coniferous tree, i.e. cuttage and breeding method for sabina vulgalis.

Background technology

Sabina vulgaris (Sabina vulgaris Ant.), another name savin juniper, savin belong to the evergreen shrub that crawls of Cupressaceae garden cypressCypressus.Originate in Xinjiang of China Tianshan Mountains to Altai Mountains, Ningxia, the Inner Mongol, northeast, Qinghai, the Qilian mountains, Gansu north slope, Yulin, on many tors ground, height above sea level 1100-3200m area and the sand dune.Introduce a fine variety on ground such as Beijing, Xi'an.The shrub that crawls, high not as good as 1m; Branch is close, tiltedly goes up exhibition, and sprig is thin, the about 1mm in footpath, subcircular.Scale leaf intersects to be close to mutually to looks, and tip is blunt or sharp slightly, and there is tangible oval body of gland at middle part, the back side; Thorn shape leaf often is born on the earsh dioecism; Be dun purple when cone is ripe, by white powder: seed 1-4 grain.Happiness light, the nice and cool dry weather of happiness, its drought resisting, cold-resistant, anti-soil depletion, adaptability is strong, can grow on calcareous soil, little sour soil earth; Contamination resistance is strong, and dust suction, deflate noise can adsorb pernicious gases such as carbon monoxide effectively, and Qi Baixiang is strong, useful health.Adaptability is strong, on the spot conditional request is not tight, and the transplanting survival rate height, diseases and insect pests resistance is strong, fast growth, its well developed root system, rudiment power is strong, can stand wind candle sand for a long time and bury, adapt to drought environment, be the fine tree species of a kind of comparatively ideal afforestation seeds and water and soil conservation.Sabina vulgaris can be taked tall mode of irritating combination in urban afforestation, plant in the isolated planting tree down, can play vertical planting effect preferably.At present, common lawn is replaced with Sabina vulgaris gradually in the part city, and prospect is very wide.

In the existing seedling growing process, Sabina vulgaris mainly adopts sowing, cottage propagation and propagation by layering.

In above-mentioned technology was used, exist at least: the seed seedling-raising cycle was long, the cuttage and seedling culture difficulty of taking root, and survival rate is not high, only be that seedling cost is big about 40-50%, and reproduction coefficient is smaller, is difficult to satisfy that the modern times afforest and the needs of urban landscaping.

Summary of the invention

At the limitation of prior art, the invention provides the high cuttage and breeding method for sabina vulgalis of a kind of reproduction coefficient.

A kind of cuttage and breeding method for sabina vulgalis, this method comprises the steps: 1. to rebuild cutting bed: after at first seedling-cultivating tray being ploughed deeply clearly assorted, basal dressing, leveling, be wide 1.8m, long 1.5m, the sunken bed of 20cm deeply; Clean river sand is laid on the seedbed the thick 5～10cm of husky bed; With 800～1000 times of carbendazim soup sterilizations;

2. adopt bar: select 1～2 year branch of robust growth, no damage by disease and insect during collection, the branch of cutting is put into the Plastic Drum that fills clear water, prevents that dehydration is withered; Adopting bar should carry out in the morning;

3. plugged ear is handled:

A: with the branch of gathering, be cut into the plugged ear of 15～20cm, needle keeps, and the clip shape of a hoof requires smooth bright and cleanly, must not tear;

B: before the cuttage, be that the auxin of 50～150ppm soaked 2～6 hours with plugged ear concentration;

4. cuttage:

A: adopt the hard rod to draw the hole oblique cutting on cutting bed, angle is advisable with 35 °～45 °, and the cuttage degree of depth is 7-9cm, and jack is wanted compacting after the cuttage, and sand is fully contacted with plugged ear; The cutting bed top is built plastic tunnel and is made the greenhouse;

B: the humidity in the plastic tunnel is controlled at 80%～90%, and temperature is controlled at 20～28 ℃, prevents seedbed ponding;

C: with concentration is 800-1000 carbendazim spraying control doubly, and every first quarter moon 1 time prevents the generation of Sabina vulgaris root rot.

Sabina vulgaris cottage propagation survival rate after utilizing the present invention to breed has realized improving the purpose of reproduction coefficient up to 75%～89%.

Embodiment

The preferable embodiment of the present invention is as follows:

A kind of cuttage and breeding method for sabina vulgalis, this method comprises the steps

1. rebuild cutting bed: after at first seedling-cultivating tray being ploughed deeply clearly assorted, basal dressing, leveling, be wide 1.8m, long 1.5m, the sunken bed of 20cm deeply; Clean river sand is laid on the seedbed the thick 5～10cm of husky bed; With 800～1000 times of carbendazim soup sterilizations;

2. adopt bar: select 1～2 year branch of robust growth, no damage by disease and insect during collection, the long 20～30cm of bar, the branch of cutting is put into the Plastic Drum that fills clear water, prevents that dehydration is withered; Adopting bar should carry out in the morning;

3. plugged ear is handled:

A: with the branch of gathering, be cut into the plugged ear of 15～20cm, needle keeps, and the clip shape of a hoof requires smooth bright and cleanly, must not tear;

B: before the cuttage, be that the auxin of 50～150ppm soaked 2～6 hours with plugged ear concentration;

4. cuttage:

A: adopt the hard rod to draw the hole oblique cutting on cutting bed, angle is advisable with 35 °～45 °, and the cuttage degree of depth is that jack is wanted compacting after the cuttage about 8cm, and sand is fully contacted with plugged ear; The cutting bed top is built plastic tunnel and is made the greenhouse; The hard rod is glass bar or smooth wooden stick;

B: the humidity in the plastic tunnel is controlled at 80%～90%, and temperature is controlled at 20～28 ℃, prevents seedbed ponding; One week began to produce the root original hase, and 40 days begin to take root.

C: with concentration is 800-1000 carbendazim spraying control doubly, and every first quarter moon 1 time prevents the generation of Sabina vulgaris root rot.

Auxin of the present invention preferentially adopts ABT series, is specially:

Adopt the ABT of 100ppm ₁, when soak time reached 2 hours, the cottage propagation survival rate reached 75%

Adopt the ABT of 150ppm ₆, when soak time reached 6 hours, the cottage propagation survival rate reached 80%

Adopt the ABT of 100ppm ₇, when soak time reached 2 hours, the cottage propagation survival rate reached 89%

The above; only adopt 50～150ppm for the present invention; dip under 2～6 hours time treatment conditions; the highest better embodiment of Sabina vulgaris cottage propagation coefficient that the ABT best of breed is handled; but protection scope of the present invention and not only be confined to this anyly is familiar with those skilled in the art, in the technical scope that the present invention discloses; variation of expecting easily and replacement all should be encompassed in protection scope of the present invention.
