Description
Technical Field
The invention relates to a method for cultivating miniature Chinese roses, belonging to the technical field of vegetative propagation and cultivation of potted horticultural plants.
Background
The miniature Chinese rose is a plant of Rosaceae and Rosa. Short and small upright shrubs with strange flower colors can be opened all the year round in the flowering phase, and the method is suitable for pot culture. Mainly used as potted plants for appreciation, lawn decoration and pattern arrangement. The miniature Chinese rose has an indispensable value in landscaping, and the Chinese rose is a flower with the largest use frequency in garden forests in south and north. The Chinese rose is a main ornamental flower in spring and has a long flowering phase. It is suitable for balcony and windowsill, desk and table, park and street green land, greening environment, and its petal can also be used for extracting perfume. Therefore, the Chinese rose has wide market prospect no matter used as a fresh cut flower or a pot plant or used for arrangement of a flower bed and a green land.
At present, the traditional cultivation mode of miniature Chinese roses adopts cutting propagation, cutting slips with 1 bud point on a lateral branch with leaves are used and are cut in a pot and cultivated until the cutting slips take roots for about 15 to 20 days; then moving the seeds into a greenhouse for cultivation until the seeds reach the pinching standard for about 30-40 days; then, pinching treatment is carried out, namely, the branches at the top end of the plant are cut off, 2-3 bud points are reserved on each branch, and sufficient nutrient solution is supplied to promote the growth of lateral branches; finally, entering a maintenance stage, cultivating in a greenhouse until flowering, and spraying a dwarfing agent according to the requirements of plant types for about 40-60 days. The total time from cuttage to finished product sale is 85-120 days. The cultivation period is long, the pinching is still carried out for 1-2 times when the plant reaches a certain length, the stem height of the plant is difficult to control due to improper pinching treatment, the bottom leaves fall off to form a bare foot phenomenon, and the ornamental value and the profit margin of the product are influenced.
In view of the above, the present invention is particularly proposed.
Disclosure of Invention
In order to achieve the above purpose of the present invention, the following technical solutions are adopted:
the invention provides a miniature Chinese rose cultivation method, which comprises the following steps:
selecting cutting shoots, culturing and rooting, and removing all visible bud points of the cutting shoots within 3 days after film uncovering to realize pinching;
the cut shoots after pinching enter a seedling reviving period of 1-2 days, and then are moved into a greenhouse for maintenance;
and maintaining at least 2-5 buds exposed to the color of the cuttings moved into the greenhouse.
Preferably, the caliber of the cuttage container is 10-12 cm, the height is 10-11 cm, and the cuttage quantity is 6-7 plants. The space and the growth vigor of the plants are reasonably utilized, 12-14 branches can germinate, no less than 10 flowers can be developed, the plants are plump, and the ornamental value is greatly improved.
Preferably, in the cultivation process, the cultivation environment humidity is 100%, the illumination intensity is not less than 10000lux in 24 hours all day, and the temperature is kept at 24-26 ℃. The survival rate of the cuttings can be improved and the rooting can be accelerated by meeting the environmental conditions.

Different growth stages have different requirements on illumination, temperature, humidity and ventilation conditions, the growth stage of plants with square areas is changed, and meanwhile, the disease probability is reduced.
Preferably, when the cutting slips are maintained in a greenhouse, the first nutrient solution and the second nutrient solution are mixed and fertilized in a bottom flood irrigation mode, and the mixing volume ratio of the first nutrient solution to the second nutrient solution is 1: 1. The nutrient solution formula belongs to a high-potassium formula, contains a large amount of potassium elements, and can improve the photosynthesis efficiency of plants, thereby improving the growth speed of crops and increasing the generation and transportation of nutrients in the crops.

The fertilizer supply frequency of the nutrient solution is changed according to different periods, and the growth of plants can be effectively promoted.
Compared with the prior art, the invention has the beneficial effects and innovation points that:
1. the traditional pinching process is improved, once pinching is carried out within 3 days of film uncovering of the cutting slips, then the cutting slips can be moved into a greenhouse to enter a maintenance stage only in a seedling revival period of 1 day at the fastest speed, only 50-70 days are needed from cutting to finished products, and the production period is greatly shortened.
2. Different from the traditional pinching standard of only cutting off the top, the pinching standard of the invention is as follows: no visible bud points are left. In 7-10 days after pinching, tender shoots can be clearly seen from two sides of the leaf stalk, and more than 90 percent of single cuttings have double-shoot expression; after 30 days of pinching, 6 to 8 new leaves can grow out from the plant.
3. Double-bud germination is easy to occur at the leaf stalks after pinching and trimming, each plant can germinate 2 branches, and the problem that leaves at the bottom of the miniature Chinese rose fall off to form a big pain point of bare feet can be effectively solved, so that the ornamental value of the product is improved.
4. Because the pinching time is early, the growth of the main stem is inhibited, the problem of high and difficult point control of the miniature Chinese rose can be solved, the using times of dwarfing agents are reduced, lateral branches can be better germinated, and the flowering uniformity of the miniature Chinese rose is improved.
