Description
Technical Field
The invention belongs to the field of agricultural planting, and particularly relates to a rapid propagation method of bellflower.
Background
The flower of the bellflower looks like a bell hung upside down, has peculiar appearance and high ornamental value. The bellflower produced in the south of China is a good product for spring decoration in Guangzhou and hong Kong before and after the flowering time is positive. However, researches on artificial propagation of the aleppos comatus and related data are few at present, and experiments show that the survival rate of the aleppos comatus cuttings is low and false survival is more caused by using a conventional woody plant cutting propagation method and management after cutting. Even if the long roots survive, the cutting seedlings of the bellflower grow very slowly and have poor growth conditions.
The conventional cutting propagation technology is that one part of the plant's nutritive organ is inserted into loose and wet soil or fine sand and the regenerated plant is rooted and branched to become new plant. Generally, the cutting slips are one-to-two-year-old thick and strong branches, most cutting beds which are leveled by manpower are used for cutting, and sandy or good-drainage substrates are used for cutting. Multiple experiments show that the method is not suitable for cutting propagation of the bellflower. The first cutting test is carried out on half-shaded open land (the open land can be sunned for several hours in noon), the cutting survival rate is only 3%, the survival rate is 2-3 years of thick branches, the growth vigor is weak, the growth length of the young shoots of the cutting slips is 8.7cm averagely in 2 years, and the length of the new roots is 5.2cm averagely. The survival rate of the second cuttage test is obviously improved to 56% at the shaded position under the bamboo forest, but the growth vigor is weak, the growth length of the young shoots of the cutting shoots is averagely 11.8cm within 1 year, and the length of the new roots is averagely 8.5 cm. Although the rooting rate is greatly improved compared with the first test, the growth potential is still weak, the plants grow slowly, and a plurality of plants are still not rooted after sampling inspection.
Therefore, the search for a cutting rapid propagation method suitable for the plumbago virgata becomes a technical problem to be solved urgently by the technical personnel in the field.
Disclosure of Invention
The invention provides a rapid propagation method of the bellflower to solve the problems, which can effectively improve the survival rate and the rooting rate of the cutting of the bellflower and enhance the growth potential of the cutting slips.
The invention adopts the following technical scheme to realize the purpose of the invention:
a rapid propagation method of bellflower comprises the following steps:
the method comprises the following steps: selecting a semi-hillside crop cuttage site in a valley, performing cuttage on a slope with the slope of 50-60 degrees, and before cuttage, turning soil and loosening soil for a cuttage bed with the depth of 40 cm.
Step two: in the middle and late 11 months; the cutting temperature is lower than 25 ℃.
Step three: selecting the time before ten points in the morning or four points in the afternoon of the previous day on the cuttage day, and avoiding the time of increasing the intermediate temperature;
step four: cutting branches: selecting mature annual branches, cutting the branches into cuttings with the length of about 25-30 cm and attached with 3-4 nodes, cutting off the lower end of the cuttings at the position close to the nodes, cutting off the cuts without roughness, removing leaves except for the top leaves, cutting off half leaves of the top leaves, and keeping the cut wet.
Step five: the iron pick opens a small ditch with the depth of about 25cm on the cutting bed, leans the cutting into the ditch, then covers soil and slightly compacts, and strictly inserts the cutting into the soil.
Step six: watering thoroughly once immediately after cuttage is finished, and watering once according to the weather condition for 2-5 days, preferably wetting the cuttage bed.
According to the rapid propagation method of the bellflower, provided by the invention, the survival rate and the rooting rate of the bellflower cuttage can be effectively improved by selecting cuttage on the slope with a certain inclination angle, and the growth vigor of the cuttings is enhanced.
Preferably, the first step further comprises selecting an under-forest shade or setting up a shade net, and the optimum ambient humidity is 75-90%.
Preferably, the canopy density of the erected shade net is 0.7-0.8.
Preferably, the fifth step further comprises soaking the cutting slips in clear water for 30min before cutting.
The invention has the beneficial effects that:
(1) the survival rate of the first year of the aleurites fordii cutting is 84%, the average length of the young shoots of the cutting is 20.4cm, and the average length of the newly born root system is 12.6 cm; the survival rate in the second year is 79%, the average length of the young shoot of the cutting is 41.8cm, and the average length of the new root system is 18.3 cm. Compared with cutting on flat ground, the survival rate is greatly improved, the growth potential is obviously improved, and the false survival phenomenon of the cutting slips is reduced.
(2) The cuttage of the invention adopts annual tender branches of the bellflower, minimizes the damage to the original plant, promotes the reproductive growth and branching of the original plant, and ensures the sustainability of the next year of branch picking and cuttage
(3) The method can fully utilize the slope land to produce the clockwork nursery stock, does not occupy the flat land and saves the land.
