Abstract
A method of culturing Chinese yew seedlings comprises the following steps: (1) the construction of a seedling bed: the seedling bed is 0.9 to 0.1m wide, and the length of the seedling bed is determined according to requirement; (2) the selection and the processing of cutting woods: a one-year branch is chosen, the tender part at the top of the branch is cut off, the branch is cut into the cutting woods which are 9 to 15 cm long respectively, (3) the cuttage of the cutting woods: holes are arranged on the seedling bed according to the density of 4cm multiplied by 5cm; (4) the final-period management of the cutting woods: within seven days after the cuttage, the humidity of a plastic greenhouse is kept at more than 90 percent, seven days after the cuttage, the humidity of the plastic greenhouse is kept at between 75 percent and 85 percent, after the cuttage, foliage dressing is carried out on the cutting woods at intervals of 7 to 10 days, (5) the transplant of the cutting woods: a ditch which is 10m multiplied by 1.2m multiplied by 0.3m is arranged in the north-south direction, 50kg/mu of calcium magnesium phosphate and 250kg/mu of organic fertilizer are spread on the ditch, so that the seedling bed is formed, after 200 to 250 days of culture in the plastic greenhouse, the cutting woods are transplanted in the seedling bed 50 cm deep according to the row spacing of 10cm multiplied by 20cm, after the transplant, the cutting woods are watered for one time until water flows out of the seedling bed; and (6 ) the management after the transplant of the cutting woods: one month after the transplant of the cutting woods, nitrogen fertilizer can be applied, and the nitrogen fertilizer is applied once every two months afterwards, so that the survival rate of the Chinese yew seedlings is improved.
Description
One, technical field
The present invention relates to a kind of method of cultivating the Chinese yew seedling, especially a kind of method that is applicable to the cultivation Chinese yew seedling in large-scale nursery.
Two, background technology
From Chinese yew, can refine taxol, taxol is the cancer-resisting medicament of generally acknowledging in the world, Chinese yew is again national class protection seeds simultaneously, because it is the red bean of Chinese yew, just like the jequirity in the southern part of the country, outer gorgeous in red, can entrust to the care of people's yearning between lovers, so liked widely in China, so Chinese yew is a kind of important forest tree species that Chinese yew can be used as medicinal kind, can also be used as the greening kind, because it is high that the Chinese yew biological property requires ecotope, its main root is not obvious, the lateral root prosperity, branches and leaves are luxuriant, sprouting power is strong, and is anti-low cold, the low temperature of ability-25 ℃; Suit to reach more than 800 meters in sea level on the average, day and night temperature reaches 7 ℃, annual mean temperature and has only 17 ℃, the bigger area growth of weather humidity spring and summer, requires P in soil H value 5.5～7.0, showing does not also have a kind of method of cultivating the Chinese yew seedling
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this invention is to provide a kind of method of cultivating the Chinese yew seedling, improved the survival rate of Chinese yew seedling.
For achieving the above object, the technical scheme that the present invention takes is: the steps include:
1, grow seedlings the bed foundation: in plastic tunnel, build the seedbed, the seedbed requires to determine on demand for wide 0.9-1.1m, length, the granularity of laying 18-22cm thickness in the bottom in seedbed is that the sand of 10-20mm is a matrix, is 800 times of carbendazim that 1: 100 and 0.5% potassium permanganate liquid 1: 200 by volume are mixed into soup with water by volume, uses soup that seedbed and plastic tunnel inside are carried out disinfection.
That 2, transplants a cutting chooses and handle: choose the branch of life in 1 year, cut the tender portion on top, segmentation is cut into the plugged ear about 9-15cm, and removing every section about 1/3 blade of plugged ear base portion is root, the root of plugged ear is put in the hestening rooting solution soaked 1-1.5 hour.
3, the cuttage of plugged ear: on the seedbed, arrange out the hole, cave, then plugged ear is put into 1/3 place of hole, cave, use the matrix compacting on every side of handgrip plugged ear again to plugged ear by 4cm * 5cm density.
4, plugged ear final-period management:
Water of spray after cuttage finishes makes till the outside flowing water of matrix energy, uses the method for spraying to keep humidity, in seven days, the humidity of plastic tunnel is remained on more than 90% after the cuttage, after seven days, makes the humidity of plastic tunnel remain on 75-85% after the cuttage;
After cuttage finishes, be 7～10 days by the cycle, plugged ear is sprayed foliage fertilizer.
5, plugged ear is transplanted:
By the north-south, be made into the trench digging of 10m * 1.2m * 0.3m, by the fused calcium magnesium phosphate of every mu of 50gk and the fertilizer of every mu of 250kg, be laid on the trench digging, thereby the formation inoculating bed, 200-250 days cultivation of process in plastic tunnel is when the root system of plugged ear becomes brown by white, with little spades matrix and plugged ear are scooped up simultaneously, matrix is dropped, press seeding row spacing 10cm * 20cm,, plugged ear is planted in the inoculating bed deeply for 50cm, water of spray after transplanting finishes makes till the outside flowing water of inoculating bed energy.
6, the management after plugged ear is transplanted:, on inoculating bed, set up shading shed when sunlight is strong excessively; Plugged ear was transplanted back one month, can append nitrogen liquid manure, appended one time nitrogen liquid manure later in per two months, append N: P: K=15 to annual October: 15: 15 1% composite fertilizer or use are that the liquid that 0.2% potassium dihydrogen phosphate and water are made at 1: 1000 sprays by weight, use diffusing white mosquito and kill mosquito spirit to carry out prevention from suffering from the diseases in the 4～June in every year, can become the Chinese yew seedling in 1～2 year.
Owing to used plastic tunnel and granularity to be matrix as the sand of 10-20mm, kept the humidity in the plastic tunnel, used rooting powder solution and foliage fertilizer, simulated the growing environment of Chinese yew seedling, therefore improved the survival rate of Chinese yew seedling.
The present invention has designed, and hestening rooting solution is set to the 5000ppm rooting powder solution.
The present invention has designed, and is mixed into foliage fertilizer at 1: 20 by weight 0.2% urea and water, is mixed into foliage fertilizer at 1: 25 by weight 0.2 potassium dihydrogen phosphate water liquid fertilizer and water, and these two kinds of foliage fertilizers are used alternatingly.
The present invention has designed, and it is 0.5% solution that nitrogen liquid manure is set to contain the N46% urea concentration.
