The method comprises the following steps: (1) cutting a semi-lignified twig from a seed tree of a broussonetia papyrifera seedling, taking the cut twig as a cutting wood, sterilizing the cutting wood and then using 0.1g to 0.2g/L auxin to treat the cutting wood; (2) inserting the cutting wood treated through the step (1) into a nutrition bag and cultivating to acquire alive cutting seedlings under the conditions that the temperature in a phytotron is 28 DEG C to 30 DEG C, the air temperature is 25 DEG C to 32 DEG C, the relative humidity of the nutrition bag is 50 percent to 70 percent, the relative air humidity is 75 percent to 80 percent, the lighting time is 5 to 7 hours per day, and the lighting intensity is 5000LUX to 6000LUX. The invention can not be influenced by the external environment. The rootage rate is more than 85 percent, and the sprouting rate is more than 85 percent.
Description
Technical field
The present invention relates to the method for a kind of cottage propagation paper mulberry.
Background technology
Paper mulberry (Broussonetia papyrifera (L.) Vent.), for the Moraceae structure belongs to deciduous tree, happiness light, speed are given birth to, suitable natural disposition is strong, the dry and cold and southern warm in the ability north; Drought-resistant barren, also can grow on the water's edge; The happiness calcium soil also can be grown on acidity, neutral soil.Paper mulberry is thick with leaves and many advantages such as resistance, growth is fast, breeding is easy is arranged, and is still the important species of township afforestation, especially is suitable as the greening of industrial and mining area and hillside fields, deserted mountain, also can be elected to be shade tree and shelter forest and use.Bark is high-quality papermaking and textile raw material; Wood structure is medium, and texture is oblique, and matter is soft, can supply utensil, furniture and fuel wood to use; The bark juice can be controlled tinea and neurodermatitis, and fruit is a tonic; The root skin is a diuretic, and leaf can be made pig feed, also can be used as medicine.
Paper mulberry is adopted to nourish and generate and can have a mind to avoid female plant, can select to have the merit staminiferous plant and bury method breedings such as root, cuttage, plant division, press strip.Early spring, in embryo the cuttage survival rate was very low, and root is inserted into motility rate and can reaches more than 70%, can reach about 80-90% with the epicormic branch cuttage survival rate; Epicormic branch cuttage is to utilize season of growth semi-lignified band Ye Lvzhi, generally is to carry out cuttage in August.
Summary of the invention
The method that the purpose of this invention is to provide a kind of north cottage propagation paper mulberry in June to August.
The method of cottage propagation paper mulberry provided by the present invention may further comprise the steps:
1) cuts the semi-lignified spray on the paper mulberry elite stand age the children and do plugged ear, after the plugged ear sterilization, handle with the growth hormone of 0.1-0.2g/L;
2) the plugged ear cuttage that will handle through step 1) is in nutritious bag, the indoor temperature of growing seedlings be 28 ℃-30 ℃, air themperature be 25-32 ℃, nutritious bag relative moisture be 50-70%, relative air humidity be 75-80%, every day light application time be that 5-7 hour, intensity of illumination are under the condition of 5000LUX-6000LUX, cultivated 20-30 days, and promptly got the cuttage seeding that survives.
Temperature is preferably 28 ℃ in the described greenhouse.
In the step 1), described plugged ear sterilization institute with medicament can be 70% the thiophanate methyl solution, 600 times of solution of 40% carbendazim of 500 times of dilute with waters etc.; Be preferably 70% thiophanate methyl solution of 500 times of dilute with waters.
Described air themperature can be by sunshade net, lid straw screen or mat, indoorly set up the control of method such as hair-dryer.
Described air themperature is preferably 30 ℃.
Described nutritious bag relative moisture is preferably 70%, and described relative air humidity is preferably 75%.
The concentration that described growth hormone is handled is preferably 0.2g/L.
Preferred 25 days of described incubation time.
In the described method, every day, light application time was 5-7 hour.
The length of described plugged ear is 8-10cm, and lower cut is cut into the inclined-plane, and upper cut is apart from bud 1.5cm.
In order to make the stalwartness of cuttage fringe growth, described plugged ear cultivating process also can spray foliage fertilizer weekly once, and the urea liquid that described foliage fertilizer can be concentration 0.1% mixes 0.2% potassium dihydrogen phosphate.
Described plugged ear cultivating process also can alternately spray the processing of killing virus of thiophanate methyl, carbendazim or a streptomycin in per 4 days.
Method of the present invention can be awfully hot at summer weather, under the situation outdoor, that indoor temperature is very high, utilize small arched shed, cold canopy in addition measures such as sunshade net, straw screen or mat, hair-dryer reduce temperature, the characteristic of paper mulberry in addition, two bud double leaf cuttages generate plant.Method of the present invention is accelerated reproduction speed, shortens the cottage propagation cycle, improves paper mulberry survival rate of seedling in summer.Show that by experiment method of the present invention is not subjected to the influence of external environment, rooting rate is more than 85%, and germination rate is more than 85%.
Embodiment
Method among the following embodiment is conventional method if no special instructions.
