Advantages of efficient and rapid propagation technology of plants without test tubes.

1, tiny explants with the length of 0.3- 1.0 cm are used as propagation unit materials, which greatly saves germplasm materials, and the amount of explant propagation unit materials is 3-8 times less than that of conventional seedling raising; The inoculation speed is extremely fast, which is 3-5 times that of tissue culture. Directly inoculated in sand beds or nutrient bags in the field, the seedlings are molded once until they are supplied for production, without any movement, and the survival rate is high. In the absence of all the conditions of tissue culture and rapid propagation in vitro, the simple seedling raising facilities are several times lower than those of tissue culture and rapid propagation, and also lower than those of conventional seedling raising.

2. Under the original simple conditions, this method can continuously and rapidly propagate in four seasons (including extreme temperatures: low temperature -35 degrees and high temperature -42 degrees) regardless of the north and south, different latitudes, different soils and different climates, and most varieties can reach 6- 12 generations. This technology is less affected by seasons, and it can be inoculated and propagated 365 days a year. On the basis of the original plant, the efficient reproduction of each generation is realized according to geometric progression. This rapid propagation technique can start production on any day of the year. Greatly expanded the time and space of technology application.

3. High permeability. Ordinary people can inoculate 3000-5000 units of materials every day (8 hours). A production technician who has been trained for four months can successfully cultivate 30,000-100,000 pure seedlings of a single plant variety every month. The adaptability to the requirements of talent quality is extremely wide, and the production technology is easy to popularize; Second, the speed of personal operation is much faster than that of tissue culture rapid propagation and conventional seedling raising. When reaching a certain seedling scale, the ratio of production investment benefit can reach more than 1:5- 1: 10. It is very economical in plant germplasm materials, and it can inoculate hundreds of thousands to millions of plants a day (which is unimaginable in tissue culture all over the world), and it is easy to propagate various seedlings quickly in a large area. It is easy to raise seedlings on a large scale, and quickly industrialize and propagate all kinds of seedlings.

4, few operation steps, simple production technology and process, easy to master after special training, and can be widely used in production. And is suitable for large-scale industrialized seedling raising. Ordinary people can participate in all the production operations of rapid propagation, and the speed is extremely fast and the seedling formation time is short, which greatly saves the comprehensive production cost and improves the production efficiency of personnel. Less one-time investment, low cost, high labor efficiency, greatly saving labor costs and improving seedling production efficiency.

5. Strong technical operability and easy industrialization. Every trained and qualified production technical backbone can manage 300,000-200,000 seedlings for different plants every month, and every ordinary person who has been trained for more than 4 months can produce 3,000-6,543.8+0,000 qualified seedlings every year. The economic benefit is extremely high. At present, there have been many project bases with an annual output of10 million plants in the industrialization development.

6, the speed of obtaining complete regenerated plants is fast, and the propagation speed is fast. The survival rate of seedlings is as high as 85%- 100%. The root system is developed, generally 3-6, and more than 30-40. Rooting time is short, most plants. From the first day of inoculation, after 15-60 days of rooting and germination, complete regenerated plants can be obtained, and seedlings can be tempered to get out of the nursery. Really achieved efficient and rapid reproduction. Each regenerated plant reproduces one generation every 15-60 days, and the multiplication coefficient of each generation is 2- 15 times. Its remarkable feature is that it can reproduce efficiently according to geometric progression on the basis of the number of original plants. This is the same as the advantage of rapid propagation of plant tissue culture in test tubes.

7. Using a set of original and effective technical system and management experience, combined with more than 200 original single or compound formulas of clonal rehydration for different plants, the technical indicators of TERNPC are formed.

8. Regenerated seedlings are robust, plants have no variation, blossom and bear fruit early, and yield is high. That year, many plants blossomed in the nursery. Some flowers bloom 20-70 days after inoculation. The flowers are large and bright, and the flowering period is longer than that cultivated by other technical methods.

9, mature seedlings, high purity, no pests and diseases, well-developed and complete roots, root length of more than 25 cm, root number of 3-6, mature and full buds, stem height of 20-60 cm, field survival rate of over 90%.

10. The green seedlings directly inoculated in nutrient bags (or plug plates) have high purity, no diseases and pests, more than 3-5 leaves, full axillary buds, strong branching ability, developed root system and high quality of hardening seedlings. The survival rate of field planting production is over 95%, and the growth rate is faster than that of conventional cutting seedlings.
