Description
Technical field
The present invention relates to a kind of cuttage and seedling culture method of southern enqlish yew, belong to plantation seedling growing process field.
Background technology
Chinese yew is also called yew, has 11 kinds in the world, and there are taxusyunnanensis, Xizang Taxus chinensis, taxus chinensis in northeast, Chinese Chinese yew, southern enqlish yew five kinds in China.Southern enqlish yew adopts Sexual breed usually, but because it is dioecism not easily solid seed, and the resting stage of seed reaches more than 1 year, even if pass through technical finesse, its germination rate, emergence rate are still lower, this brings certain difficulty to sexual propagation, and the seedling growth of sexual propagation is simultaneously slow, brings many adverse influences to the development and utilization of southern enqlish yew resource.
Summary of the invention
The object of the invention is the shortcoming in order to solve the low breeding difficulty of southern enqlish yew survival rate, providing a kind of method simple, the cuttage and seedling culture method of the southern enqlish yew of strong operability.
The present invention adopts following technical scheme: a kind of cuttage and seedling culture method of southern enqlish yew, and the method for cuttage and seedling culture adopts following steps to realize:
(1) early-stage preparations of cuttage: 1. set up cuttage seedbed, be built into height about 25-30cm with brick, the seedbed of wide 0.8-1.2m, then flattens, and matrix is evenly laid on seedbed, and thickness is 20-25cm, puts down; 2. equipment is installed, and adopts the method for greenhouse cuttage and seedling culture on seedbed, to install automatic spraying system, at canopy face covered with sunshade net;
(2) the choosing and processing of cuttings: 1. cuttings adopts the branch that annual or biennial base portion is newly sprouted, be cut into the segment that 12-15cm is long, 2 ~ 3 winglike compound leaves are stayed on segment top, and the blade of bottom is all extractd, and the age of tree of cuttings should not be longer than 15 years; 2. the process of cuttings, the cuttings that clip gets off, putting into concentration is that the indolebutyric acid solution of 90-100ppm soaks 2-3h, hestening rooting rate and the quality of taking root;
(3) cottage method: cutting time elects 15-October 15 annual September as, should cuttage immediately through the cuttings handled well, and seeding row spacing is 5-7 cm × 5-7cm, and the degree of depth of insertion is 5-8cm, should water permeable after being plugged immediately;
(4) manage after cuttage: routine observation canopy humidity, relative moisture is made to remain 70-80%, keep blade moistening, prevent leaves water loss from here withering, in order to photosynthesis, accelerate the differentiation of root system and growth, temperature is set to 25-28 DEG C, the every 30-40 days spray solutions with the urea of 0.15-0.25% and the potassium dihydrogen phosphate of 0.2-0.3% after taking root; Southern enqlish yew happiness is shady and cool, and canopy face adopts 50-70% Shading net covering.
Further, the matrix in described step (1) adopts perlite and peat composed of rotten mosses ash to combine, and perlite and peat composed of rotten mosses ash are 5:2-3 Homogeneous phase mixing in mass ratio, and be exposed to the sun after mixing 2-3 days.
The inventive method is simple, and strong operability, adopts this kind of method to make the rooting rate of southern enqlish yew high, and root system is healthy and strong, and transplanting survival rate is high, and the breeding efficiency of southern enqlish yew significantly improves, and contributes to the popularizing planting of southern enqlish yew.
