Abstract
The invention discloses a Camellia crapnelliana cutting propagation method. The method includes the steps of cutting a one-year-old branch of Camellia crapnelliana into cuttings as required, soaking the cut cuttings into an ABT aqueous solution, transplanting the cuttings to a nutrition bag after the cuttings are inserted into a sand bed for 75 days, routinely managing the cuttings according to the requirements for nursery fields, and conducting fertilization and insect and disease prevention according to the growth conditions of nursery stocks, wherein the cuttings can be transplanted out of the nursery fields and planted in fields about 180 days later. According to the method, not only can the seedling source guarantee be provided for large-scale plantation of Camellia crapnelliana, but also the propagation method is provided for the seed selection of the high-yield and high-quality single plant of Camellia crapnelliana, and therefore the progenies can well keep the excellent characteristics of the female parent. The method is high in success rate, convenient to operate and easy to popularize and apply, and has good market application prospects.
Description
Technical field:
The invention belongs to field of plant growing technology, be specifically related to the asexual reproduction method of oil plants C. crapnelliana, particularly a kind of cuttage breeding method of C. crapnelliana.
Background technology:
C. crapnelliana (Camellia crapnelliana Tutch.) dungarunga, high 5-7 rice, bark is red, and spray is without hair.Leaf hard leather matter, the shape of falling ovum is oval to oval, long 8-12 centimetre, wide 4-5 centimetre, the short point of tip, and tip is blunt, base portion wedge shape, above bottle green, below celadon, without hair, lateral vein about 6 is right, not obvious above, obvious projection below, there is thin cognate at edge, and the long 6-10 millimeter of petiole, without hair.Hua Dingsheng, Dan Hua, diameter 7-10 centimetre, nearly stockless; Bract 3, is close to sepal; Sepal 5, obovate, long 1-1.7 centimetre, wide 2 centimetres, there is fine hair in outside, comes off; Corolla white, long 4-4.5 centimetre, petal 6-8 sheet, obovate, long 3-4 centimetre, wide 1-2.2 centimetre, base portion adhesion is about 4-5 millimeter, and outermost 1-2 sheet is closely from life, and base portion is slightly thick, keratin, back side hairiness; Long 1.2 centimetres of stamen, takes turns more, without hair, and foreign steamer filigree and petal adhesion about 5 millimeters; Ovary hairiness, style 3, long 1.5 centimetres, hairiness.The every room 4-6 of ovule.Capsule is spherical, diameter 6-10 centimetre, the thick 1-2 centimetre of pericarp, loose porous gap after dry, Room 3, and every room has seed 3-5.
C. crapnelliana plant type is attractive in appearance, and Hua great, fruit greatly, can be used as excellent view seeds and the use of deserted mountain stand improvement.
Grease is one of necessary nutrient component of human physiological metabolism and origin of heat, and C. crapnelliana fat content reaches 47.5%, and saturated fatty acid and unsaturated fatty acid, close to oil tea, are good edible oils.In addition, the grease of C. crapnelliana, the predicted value of the main performance index of its iodine number, fatty acid composition and the Cetane number of corresponding biodiesel, dynamic viscosity and cold filter plugging point reaches associated biomolecule diesel oil index request, from the adaptability of grease, C. crapnelliana grease is also applicable to production biodiesel.Therefore, the grease of C. crapnelliana is edible or industrial all has very large economic worth.The forest products of plantation C. crapnelliana every mu can reach 3000 yuan, and economic worth is higher, the exploitation of industrialized development C. crapnelliana artificial planting and products thereof, significant to the income of promotion local economic development, raising peasant.C. crapnelliana single plant yield is higher, and fat content is high, but C. crapnelliana in the wild plant is rare, in distribution of being scattered about like the stars, produces Hong Kong, south Guangxi, Fujian, Jiangxi and Southern Zhejiang.Therefore, want to develop and utilize as industry, only obtain a large amount of seedling from sexual propagation and seed propagation, need to gather a large amount of seed seedling-raisings, have certain difficulty, therefore, need to solve seedling source problem from other approach.
Summary of the invention:
The object of this invention is to provide a kind of easy and simple to handle, with low cost, a large amount of seedlings can be provided, can also early flowering result, keep the cuttage breeding method of the C. crapnelliana of maternal good characteristic.
The cuttage breeding method of C. crapnelliana of the present invention, is characterized in that, comprises the following steps:
A, select draughty plot to surround furrow, dose clean river sand and superphosphate mixture in furrow as cutting medium, the amount of application of superphosphate is 15g/m
2, build frame above seedbed, and add a cover the shading screen that shade rate is 80-90%;
B, collection cutting: in annual 3-5 month, gather C. crapnelliana 1 year raw branch as cutting;
C, in the cool, with secateurs, branch is cut into the cutting of long 8-12 centimetre, upper end-grain cutting is put down, and lower end base portion is cut into inclined-plane, and cut surface requires smooth, smooth;
D, cutting base portion 2-3 centimetre sheared is built in 50% naphthalene second Yin second soluble powder 0.1g/L solution and soaks 4 hours, to be inserted after taking out;
E, by the cutting after Step d process by spacing in the rows 4-6 centimetre, line-spacing 10-15 centimetre, degree of depth 4-6 cm vertical inserts in the cutting medium in seedbed;
F, seedbed management: water permeable after cuttage immediately, then water once with 50% carbendazol wettable powder 500-600 times liquid, keeps husky bed moistening later;
G, transplanting pack: after cuttage 75-90 days, the seedling taken root is extracted in the Nutrition Soil migrated in nutritious bag from seedbed, add a cover the cool canopy of shade rate 80-90%;
H, nursery bed management: after seedling replanting, press nursery lot Routine Management, being separated by, within one week, combining waters to water with 50% carbendazol wettable powder 500-600 times liquid executes once, according to the growing state of nursery stock, impose with thin night soil or nitrogen, phosphorus, K composite fertilizer, or use liquid level nutrient solution to make foliage fertilization, obtain the seedling of the C. crapnelliana that can plant thus.
In step a, described furrow are wide is preferably 100-120 centimetre, and furrow are long not to be limit, the high 15-20 centimetre of surrounding's block of furrow.
In step g, the Nutrition Soil composition in described nutritious bag is made up of according to mass ratio 6:3:1 red soil, peat soil, coconut palm chaff, after mixing, is loaded in nutritious bag by Nutrition Soil.
The present invention can not only provide seedling guarantee for the large-scale planting of C. crapnelliana; and the seed selection that can be C. crapnelliana high yield fine individual plant provides propagation method; offspring is made to maintain maternal good characteristic preferably; the method has advantage easy and simple to handle, with low cost, has good market application foreground.
