Briefly talk about the advantages of non-test tube efficient and rapid plant propagation technology.

Compared with plant tissue culture, in vitro rapid propagation and traditional seedling breeding technology, the non-test tube high-efficiency and rapid plant propagation technology has the following advancements:

1. Use one leaf and one bud plant explants for The propagation unit materials are directly inoculated in the field sand bed or nutrient bags, and the seedlings are grown until supplied for production without any movement, and the survival rate is high.

2. Regardless of the south or the north, different latitudes, different soils, and different climates, this method can be used for continuous and rapid propagation all year round. From the second generation onwards, most varieties can reach 6-12 generations. This rapid propagation technology can be used to start production at any time, 365 days a year, expanding the time and space for technology application.

3. Technical operations have been quickly promoted. After a period of training, ordinary laborers who are qualified can inoculate 3,000--5,000 units of materials every day (8 hours). Long-term promotion practice has proved that: first, the requirements for the quality of production technicians are not high, the technical training period is short, the adaptability is extremely wide, and it is easy to promote; second, the individual operation speed is faster than tissue culture rapid propagation and conventional seedling breeding. If the organization is managed properly, When other conditions are met, each base can quickly inoculate 200,000 to 1 million units of propagation materials every day. The technology is easy to promote on a large scale, which is incomparable to in vitro rapid propagation technology.

4. Ordinary personnel who have undergone planned training can participate in rapid propagation operations, and the inoculation speed is extremely fast (several times faster than the rapid propagation inoculation speed of tissue culture test tubes. From the second generation onwards, most plants exceed It exceeds the speed of conventional seedling breeding operations and the speed of rapid in vitro propagation, which greatly saves labor expenses and improves labor efficiency).

5. Under the guidance of the technical inventor or the inventor’s technical assistant, each qualified technical worker who has undergone a period of training can produce and manage 20,000 to 100,000 seedlings per month, and each backbone plus a certain number of auxiliary workers At least 300,000 seedlings can be produced every six months, creating extremely high economic benefits. After four months of intensive training, new employees can carry out large-scale production and seedling cultivation of a single plant variety under the guidance of technical assistants.

6. After most plants are cultivated to the second generation using plant non-test tube high-efficiency and fast propagation technology, complete regenerated plants can be obtained in 4-11 days, with a regenerated plant rate of more than 90%, truly realizing high-efficiency and fast propagation. . Some plants have special rooting and reproduction conditions, such as pine, spruce, yew, camphor, rock osmanthus, Chinese orchid, peony, etc., and their rooting lasts for a long time. But it is still faster than test tube rapid propagation and regular seedling breeding, and the overall rapid propagation efficiency is higher.

7. After the second generation of most plants, each regenerated plant reproduces one generation every 30-60 days, and the multiplication coefficient of each generation is 2-15 times (it is highly efficient based on the geometric series based on the number of original plants) proliferation). This is more prominent than the advantage of rapid propagation in tissue culture test tubes. The later generations, the more germplasm materials are reproduced, and the faster the reproduction speed.

8. There are few technical steps and short time, which greatly saves the comprehensive production cost and improves the production efficiency of personnel. Starting from micro-materials, plants that grow under natural conditions can be directly cultivated. Most plants only need 15-60 days of cultivation without any transplanting before they can be used for production cultivation, and the plants all show early flowering and fruiting, and good yield.

9. Mature seedlings cultivated by this method , high purity, free of pests and diseases, well-developed and complete root system, root length of more than 25 cm, root number of 3-6, mature buds full, stem height of 20-60 cm, and field survival rate of planting and production of more than 90%. Coniferous tree species are 5 cm to 15 cm long, and the survival rate for colonization in mountains is generally as high as 95% or more.

10. Green seedlings directly inoculated and cultured in nutrient bags during the plant growth season are of high purity, free of diseases and pests, grow more than 3-5 leaves, have full axillary buds, strong branching ability, and developed root systems. The quality of hardened seedlings is high, and the field survival rate for field planting is over 95%.

11. For many plants, the first generation is normal. Large-scale rapid propagation production can be carried out immediately. However, some plants that are difficult to propagate can only meet the technical requirements from the second generation. The main goal of the first generation of these seedlings is to obtain as many original basic seedlings as possible to lay a good foundation for normal production after the second generation.
