Background technology
Six lobe Tutcherias (Tutcheria hexalocularia) are Theaceae Tutcheria aiphyllium, and high 12 meters, spray is thick, without hair; Leaf keratin, ellipse, alternate, there is sawtooth at edge; Flower both sexes, white or faint yellow, be singly born in a top armpit 5~June of florescence; Capsule oblate spheroid, wide 5~6 centimetres, high 3~3.7 centimetres, Room 6,6 slit bamboo or chopped woods are split, by brown hair.Six lobe Tutcherias are mainly distributed in the ground such as Guangxi and Guangdong, Yunnan.Six lobe Tutcheria trunks are perfectly straight, tree-like attractive in appearance; Leaf look BG; Summer-flowering, flower amount is large, white color or yellowish; Can be used for garden, park or street planting; Its timber is hard, material is good, is the ideal material of furniture making, engraving and building materials.Therefore, six lobe Tutcherias are a kind of fine tree species of viewing and admiring and using material that integrate.
The existing Wild plant of six lobe Tutcherias seldom, is a kind of rare plant, has been listed in Guangxi and has laid special stress on protecting wild plant.Tutcheria plant adopts seminal propagation more, less about the grow seedlings document of aspect of Tutcheria plant cuttage.2004, the employing seedbed cuttage raise seedling techniques such as Xiao Fuming were bred the different plant species of this genus---Tutcheria (Tutcheria champion) (Xiao Fuming, Wang Wei, Du Qiang etc. Tutcheria cuttage raise seedling technique [J]. forestry practical technique, 2004,11:44), cuttage survival rate reaches more than 90%.But so far there are no reports relevant for the container cutting plant culture of six lobe Tutcherias.In recent years, inventor adopts seedbed cuttage raise seedling technique to breed six lobe Tutcherias, cuttage survival rate reaches 61%, but transplanting survival rate when annual six lobe Tutcherias shift out field planting to nursery from seedbed is only 20~30%, show that cuttage raise seedling technique using value in the breeding of six lobe Tutcherias in seedbed is lower.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method of simple, six lobe Tutcheria container cutting plant cultures that survival rate is high.
For solving the problems of the technologies described above, the present invention by the following technical solutions: the method for six lobe Tutcheria container cutting plant cultures, comprises the following steps:
(1) garden ground is selected: select near water source, leeward on the sunny side, draining is good, landform is smooth, chad is few plot is ground, garden;
(2) wholely: the foreign material that weed a garden, break up the clods, the landform depending on ground, garden, plays furrow by the specification level land of wide 1m, long 10m~20m, retains the pavement of width 0.5m between two furrow;
(3) matrix is prepared: seedling medium packs , Zhuan Full compacting in container for plant growth into, by row, neatly puts on seedbed, finishes rear around container ridging, and ridging is highly 8cm~10cm;
(4) matrix sterilization: in cuttage first 1 day, use 1000 times of liquid of 80% carbendazol wettable powder or 600~800 times of solution of 70% tpn wetting powder matrix of drenching;
(5) cutting collection: early September, select six lobe Tutcheria fine individual plants, peripheral at its tree crown, the lignification branch of clip life in 1~2 year, robust growth;
(6) cuttings is cut system: with sharp blade, cutting is cut into the cuttings with 2 leaf 3 buds, blade is stayed in cuttings upper end, and cuttings lower end is whittled into horse ear shape;
(7) cuttings is processed: before cuttage with No. GGR6 3~5 seconds of (two gill-No. 6 root-inducing powder, Chinese forest-science academy produces) quickly dipped processing cuttings;
(8) cuttage: water drenches matrix before cuttage, is used the bamboo let that is slightly coarser than cuttings to punch in matrix, and hole depth is cutting length 1/2, in the patchhole of cuttings lower end, compresses matrix the water of drenching;
(9) moisturizing: put up the little shed moisturizing of plastic film of sagitta 40cm~45cm, suitable trickle when the globule reduces inside plastic film;
(10) shelter from heat or light: above plastic canopy, put up black shade net and shelter from heat or light;
(11) take root after management: 7~8 months cuttage rootings after cuttage, the plastic film of raising shed two ends is ventilated, raises film after 1 week completely; After taking root, depending on the dry wet degree of matrix, suitably water, interval is used 0.2% potassium dihydrogen phosphate aqueous solution to spray blade face once for 8~10 days.
Six lobe Tutcheria fine individual plants are the one-tenth trees in age of life in 15~20 years, and plant strain growth is vigorous, without damage by disease and insect, and the amount of blooming is large, and flower is large, and color is more yellow.
Seedling medium is peat soil, and pH value is 5.16~5.22; Container for plant growth is black plastic nutritious bag, and specification is 12cm * 14cm.
No. GGR6 quickly dipped processing undertaken by following operation: first by No. GGR6, be mixed with the aqueous solution that concentration is 300mg/L~500mg/L, in 100ml solution, add the talcous ratio of 150g to add talcum powder, stir, make GGR6 solution and talcous mixture can be attached in cuttings; The part of cuttings lower end 1.5cm~2cm is dipped in said mixture.
Six lobe Tutcherias adopt seminal propagation to be easier to, but sexual propagation offspring individual difference is remarkable, and pattern is white or yellowish, and the cycle that plant maturation is bloomed is very long.For a large amount of, obtain the six lobe Tutcheria plant that botany proterties neat and consistent, pattern are more yellow, bloom early, and guarantee that it has higher reproduction coefficient and transplanting survival rate, inventor selects six lobe Tutcheria fine individual plants (the one-tenth trees in age of life in 15~20 years, plant strain growth is vigorous, without damage by disease and insect, the amount of blooming is large, and flower is large, and color is more yellow) as adopting fringe maternal plant, carry out the technical research of container cutting plant culture, thereby set up the method for the present invention's six lobe Tutcheria container cutting plant cultures.This method is simple to operate, production cost is low, be applicable to the vegetative propagation of six lobe Tutcheria fine individual plants, the offspring plant container seedling obtaining and the genetic character of fine individual plant are consistent, bloom and do sth. in advance compared with tree seedling, cuttage survival rate can reach 88%, and the transplanting survival rate of annual container cutting propagation seedling field planting during to nursery reaches more than 95%.Application the present invention can effectively solve the breeding of six lobe Tutcheria fine individual plants and transplant a difficult problem; the batch that can be used for rare plant and good ornamental tree species six lobe Tutcherias is grown seedlings; can crack Guangxi and lay special stress on protecting the difficult problem of growing seedlings of wild plant six lobe Tutcherias, be conducive to the protection of rare plant six lobe Tutcheria resources and the application in afforestation thereof.
