Background technology

Emblic (phyllansthusemblica) is Euphorbiaceae Leafflower dungarunga, and popular name olive, Yunnan olive etc., originate from the torrid areas of the southeast, Asia.Emblic distribution covers 70 ° of-122 ° of E, the vast region of 1 ° of-29 ° of N, and from the Himalayas to Sri Lanka, the Strait of Malacca, and there is distribution the tropical and subtropical region of SOUTHERN CHINA.Yunnan Province's wild emblic resource is very abundant, other grow compared with area with the whole nation, there is distribution height above sea level relatively high, the features such as distribution area is large, mainly be distributed in the dry-hot valley region, part section of the five large water systems such as Jinsha jiang River inside the province, the Lancang River, Nujiang, Yuanjiang River, Nanpanjiang River, be in Subtropical Evergreen Broad-leaf Forest and the torrid zone uncommon tree grassland ecological of (on the south 27 ° of 40 ' N) on the south Hengduan mountain range.Due to unique geographical climate environment of Hengduan mountain range, have accumulated the genetic diversity that emblic is abundant, wild resource is quite abundant.Dry-hot valley light, thermal resource are abundant, and in recent years, this region has become the focus of Land Resources Exploitation and investment, and due to large-scale land development, wild emblic resource is subject to serious destruction, even becomes extinct.Therefore, the collection of emblic resource, protection work seem quite important.

But emblic fruit tree is as other many fruit trees, large with seminal propagation variation, cannot keep the merits such as the large fruit fine quality production of former elite stand, therefore elite stand cannot expand utilization over nearly 200 years always.Therefore a kind of asexual reproduction method of the practicable for large beautiful Phyllanthus embical fruit is provided just to seem particularly necessary.At present, summer due to temperature high, the easily problem such as corrupt, the survival rate of summer grafting Yunnan olive is very low.

Summary of the invention

For the problem that the survival rate solving the olive summer grafting existence of existing Yunnan is low, the present invention proposes a kind of Yunnan olive grafting method, this grafting method by summer Yunnan olive grafting time select become a fine day after the rain after, not only be conducive to problem when reducing grafting, and not easily go mouldy, and wild Yunnan olive is selected to improve Yunnan olive grafting survival rate as stock.

Technical scheme of the present invention is achieved in that

A kind of Yunnan olive grafting method, comprises the steps:

Step a: select wild Yunnan olive as stock;

Step b: obtain scion;

Step c: in summer and be after the sun shines again after the rain, gets described stock and carries out engaging with described scion and tie up film.

Further, the method obtaining stock described in step a is specially apart from the sawed-off stock trunk in 60-70cm place, ground, and otch tilts, and in low side along between skin zone with xylem or be slightly with the vertical lower partial application of xylem in the incision of stock central vertical, obtains otch.

Further, the notch depth of described stock is 4cm-5cm.

Further, obtaining scion is the high and stable yield prime of life Yunnan olive choosing result, to adopt on tree crown the branch that the 1-2 at middle part is raw, the bud getting its stage casing as scion, with adopting with connecing; Choose the scion similar to stock size, the smooth kerf of 2-3 centimetre below eye.

Further, the notch depth of described scion is 3cm-4cm.

Further, engaging with tying up film described in step c is that the formation layer of the otch of described stock engages with the formation layer of the otch of described scion, then from bottom to up anvil fringe is hindered bread with plastic strip and tightens.

Further, described step c also comprises and prevents composition surface from soaking, and keep illumination, after grafting, inspections in about 10 days survives situation, and instant benefit connects; As the long 17-20 centimetre of scion rudiment, during branch semi-lignified, remove film strip, grafting success.

The present invention adopts grafting vegetative manner, is at utmost preserving the characteristic of Yunnan olive female parent, realizes scale, industrialization production development.The restraining factors survived are affected more for summer grafting, mainly temperature is on surviving the impact caused, after grafting time of the present invention is selected to become a fine day after the rain, not only be conducive to problem when reducing grafting, and not easily go mouldy, and wild Yunnan olive is selected to improve Yunnan olive grafting survival rate as stock.

Embodiment

Embodiment 1

Experimental field natural conditions

Experimental field be positioned at hot-zone, academy of agricultural sciences of Yunnan Province, Yuanmou County Yuan Ma town, dry-hot valley of Jinshajiang River ecological agriculture research institute emblic, tamarind Germplasm Resources, belong to typical xeothermic monsoon climate, height above sea level 1100m, dry hot short of rain, average temperature of the whole year 21.9 DEG C, thermal extremes 42 DEG C, extreme low temperature-0.1 DEG C; Year sunshine duration 2670.4h; Average annual rainfall 616.7mm, year evaporation discharge be 6.4 times of rainfall, annual relative moisture 53.0%; It is experimental field tableland, gentle slope.The wild emblic distribution of this region is wide, area is large, genetic diversity enriches, one of best region be the collection of emblic resource, preserve, studied.

1.2 Root-stock selection

In emblic, tamarind Germplasm Resources, selective light is according to sufficient, the plot of ventilation and penetrating light, the wild emblic of life in 2 years as stock, growth selection gesture by force, be stock without the plant of growing directly from seeds of damage by disease and insect, stock seeding row spacing is 3 × 3m.

Stock process before 1.3 graftings

Wipe out all branches before grafting, trunk height 60-70cm place truncation, every strain stock stays the grafting of 1-2 head, and grafting is a few days ago poured water 1 time, thoroughly removes the weeds around stock.

Scion is selected
