Chinese tamarisk generally adopts the method for seed propagation.Along with Chinese tamarisk is in recent years subject to more and more higher attention as afforestation trees, also there is the cuttage breeding method of Chinese tamarisk now.The main points of this method are: 1. the time is in the majority in spring; 2. complete lignified Chinese tamarisk branch of cuttage strip adoption; 3. in cultivating process, use Nutrition Soil.Make can realize in spring in this way the breeding of Chinese tamarisk.
But, find not have at present a kind of method that can realize in summer Chinese tamarisk Fast-propagation through retrieval.Trace it to its cause, mainly contain: 1. the branch in summer mostly is incomplete lignified branch; 2. temperature is very high, is very easy to occur listless seedling; 3. ground temperature is very high, easily occurs butt rot.This just need to design a kind of more reasonable and practical Chinese tamarisk seedling method for quickly breeding in summer.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Chinese tamarisk seedling method for quickly breeding in summer, and it is applicable to 6-9 month Chinese tamarisk be carried out to Fast-propagation, thereby eliminates defect in above-mentioned background technology.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of Chinese tamarisk seedling method for quickly breeding in summer, comprises the steps:
The incomplete lignified Chinese tamarisk branch that step 1. is chosen is then cut into cuttage bar.
In this step, what first choose is incomplete lignified Chinese tamarisk branch, is different from traditional complete lignified Chinese tamarisk branch of selecting; Secondly, inventor finds in a large amount of exploration practice, in the time selecting incomplete lignified Chinese tamarisk branch to carry out breeding summer, the length of cuttage bar should be 5～8cm, preferred length is 7cm, preferably retain 1～2 blade, under this length and blade reservation amount, incomplete lignified Chinese tamarisk branch is the most easily taken root and is survived.
In addition, in order to promote cuttage bar Rapid Rooting, described cuttage bar is before cuttage, and root first utilizes rooting powder solution to soak, soak time 2～5 minutes.Root-inducing powder is commercially available ABT6 root-inducing powder, and solution concentration is 200～300ppm.
Step 2. enters to be loaded with in the nutritive cube of sandy soil by the cuttage of cuttage bar, puts in booth nursery, and in booth nursery, temperature is controlled at 20～30 DEG C.
In this step, booth nursery arranges sunshade net, in order to lower the temperature, to prevent that daylight directly shines.And, sandy soil are special sandy soil, be different from traditional Nutrition Soil, it is the mixture of fine sand and common soil, the part by weight of fine sand and common soil is 2.5:1～1.5:1, the part by weight of fine sand and common soil is preferably 2:1, does not contain any fertilizer or inorganic fertilizer in described sandy soil, and permeability is good; The common soil at this place, refers to the soil of taking from booth nursery, can be saline-alkali soil.
The cuttage degree of depth of cuttage bar is 3/4～2/3 of cuttage bar height, and under this cuttage degree of depth, incomplete lignified Chinese tamarisk branch is the most easily taken root and survived, and crosses shallow easy listless seedling, crosses deeply easily butt rot.
The density of putting of cuttage bar is 80～100/square metre.
Cuttage bar is carried out trickle processing by step 3., keeps blade moistening.
In this step, adopt the spray equipment arranging in booth nursery or manually cuttage bar carried out to trickle, trickle has following effect: prevent the dehydration of cuttage bar 1.; 2. reduce the temperature in booth nursery; 3. reduce the temperature of sandy soil in nutritive cube.Inventor draws best trickle scheme in a large amount of experiments repeatedly: before sprouting, in the time that trickle is processed, every 15～20 minutes sprays 2 minutes, preferably spray 2 minutes in every 20 minutes; Can sprout in about cuttage bar two weeks, go out after sprouting, and trickle frequency reduces half left and right, every 30～40 minutes sprays 2 minutes, and preferably when every 30 minutes sprays 2 minutes, trickle speed can control on demand, is advisable to irrigate sandy soil.In the time adopting above-mentioned trickle scheme, cultivation effect is best, and incomplete lignified Chinese tamarisk branch also the most easily survives; Go out after sprouting, preferably executed one time foliage fertilizer every 7～10 days.Foliage fertilizer can promote blade growth, carry out photosynthesis, to promote taking root of cuttage bar.
In this step, booth is provided with sunshade net on nursery, and the ventilating system that the temperature in booth nursery relies on sunshade net, trickle and booth nursery to carry is controlled.
