Description
Technical field
The invention belongs to plant cuttage propagation field, relate to the cottage propagation of screw oil expeller wood, be specifically related to a kind of screw oil expeller wood Water culture propagation method.
Background technology
Screw oil expeller wood, (SyzyglumhanceiMerr.EtPerry) calls: red squama Portugal, screw oil expeller.Evergreen dungarunga, Gao Keda 6 meters, one of rare red-leaf plants shown unique characteristics in current south.Tree-shaped is compact, and branches and leaves are dense, easily prunes shaping.Happiness light, high temperature resistant, not moisture-proof, requires loose, well-drained soil.Screw oil expeller wood is introduced from the ground such as Australia, Southeast Asia, and high temperature resistant, the young leaves four seasons are scarlet, and in its process of growth, red, orange, bottle green presents successively, and color is lasting; Tree-like grace, branches and leaves are dense, easily prune shaping, can be used as hedgerow, hedge and shaping shrub etc., the ground plantation such as to be suitable in China Hong Kong, Macao, Guangdong, Guangxi, Hainan, Fujian, Kunming.This plant is planted experimentally especially by many enterprise's plantation families, afforestation project company now,
guangzhou College Citylandscape design,
two sand islands's
overall planningdeng, all using the emphasis of the screw oil expeller of fragrant for China gardening as its design planning.In Singapore, screw oil expeller wood is a kind of very general
ornamental foliage plant, be mainly used in view landscape architecture and large-scale
landscape engineeringon, plant in trade with the moulding such as spherical, layer shape, turriform, natural shape, cylindrical, taper, garden, also may be used on Lv Qiang, green Li, tree Li, mass-planting, by the colored view of plate and large-scale mangrove forest, view and admire the effect of its four seasons multicolour change.In the country such as the U.S., Canada
afforestationin, the cultivated area of colored tree is very large, can reach 50% to 60% of trees total amount.At present, China's Urban Greening also beautifies from the simple green coloured silkization that changes into of building.Predictably, the ratio regular meeting of colored tree in China city progressively improves, and is expected to reach 15% to 20% of trees total amount.Screw oil expeller wood conventional seedbed system method is graft seedling growth, but the grafting method cycle is long, and efficiency is low, and fructufy has certain variability.Prior art also has and adopts the method for cuttage and seedling culture, but screw oil expeller wood Cutting conditions and environment wayward, thus cause the instability of survival rate.
Summary of the invention
The present invention, in order to overcome the deficiencies in the prior art, provides a kind of cultivation period short, the screw oil expeller wood Water culture propagation method of taking root fast, environment controllability is good, condition of culture is stablized, survival rate is high.
In order to realize foregoing invention object, the technical solution used in the present invention is as follows:
A kind of screw oil expeller wood Water culture propagation method, comprise cuttings sampling and processing, the preparation of nutrient solution, the preparation of cuttage vessel, water planting cultivated, the operation of management and acclimatization and transplants after cuttage, the raw then semi-lignified that growth selection is healthy and strong, bud is good, disease-free or lignified screw oil expeller wood young sprout, insert to be equipped with in the cuttage vessel of nutrient solution after pruning modes and carry out water planting cultivation, control condition of culture, carry out acclimatization and transplants after obtaining growing up to the cuttings of young root, obtain screw oil expeller wood nursery stock; Its concrete operation step is as follows:
(1) cuttings sampling and processing: the raw then semi-lignified that growth selection is healthy and strong, bud is good, disease-free or lignified screw oil expeller wood young sprout, be trimmed to the branch of the two bud of double leaf of 8-10cm as cuttings, cuttings bottom is cut into inclined-plane, cuttings base portion 2-4cm is submerged to take out after soaking 60-90min in 60mg/kgABT2 rooting powder solution and dry, for subsequent use;
(2) preparation of nutrient solution: its material content of nutrient solution is: 1/2MS+NAA0.4-1.5mg/L+GGR1.0-2.0mg/L+PG30-50mg/L+ sucrose 10g/L+ agar 2.0-5.0g/L+ active carbon 1.0-2.5g/L, adds sodium hydroxide solution and nutrient solution pH value is adjusted to 5.8-6.2;
(3) preparation of cuttage vessel: the casing selecting glass to make in cuttage indoor is as cuttage vessel, and pour nutrient solution in cuttage vessel, Depth Nutrient Solution is 3-5cm; And be cut into cuttage vessel size with flexible plastic cave dish, and punch, as cuttings fixed head at cavities place card punch;
(4) water planting is cultivated: cuttings step (1) obtained is inserted in the aperture of cuttings fixed head, and makes cuttings inclination 30-45 °, is then placed in cuttage vessel;
(5) manage after cuttage: room temperature controls as 20-30 DEG C, indoor humidity controls as 80-100%, and solution temperature controls as 15-20 DEG C, and nutrient solution is changed in timing; With oxygen pump and heating rod to the nutrient solution oxygenation in cuttage vessel, heat;
(6) acclimatization and transplants: when the cuttings young root of water planting grow to 1-2cm long time, implanting in seedling medium and to be colonizated in furrow, the degree of depth implanting matrix is 4cm; After transplanting, every day waters 1 water, successively decreases, avoid direct sunlight after 10 days, obtains screw oil expeller wood nursery stock.
Preferably, in above step (5), the frequency of oxygenation is every 7h ventilation 1h; Every 10d changes one time of nutrition liquid, and the degree of depth keeping nutrient solution is 3-5cm, supplements in time when liquid level declines with distilled water.
Preferably, the wide 20-30cm of casing described in above step (3), long 50-60cm, dark 20-25cm; Aperture 1.0cm on described cuttings fixed head.
Preferably, the seedling medium described in above step (6) is formed by peat soil and yellow sand mud Homogeneous phase mixing.
Relative to prior art, the advantage that the present invention has and beneficial effect as follows:
1, the present invention prepares excellent nutrient solution, have adjusted the pH value benefiting screw oil expeller wood and take root, and by the impact on screw oil expeller wood cuttage root-taking such as nutritive element, plant growth regulator, improves cutting plantation; Meanwhile, in cottage propagation process, the condition such as temperature, humidity, ventilation is completely controlled, and nutrient component absorbing capacity is strong, and well developed root system, cutting plantation is high and stable.
2, the present invention utilizes homemade casing to carry out Water culture cultivation as cuttage vessel; overcome the problem that cuttage is subject to time restriction season; all cottage propagation can be carried out throughout the year; cuttings survival rate more than 93%; be applicable to large-scale production; can widely popularize, there are good economic benefit, social benefit and ecological benefits.
