Description
Technical Field
The invention belongs to the technical field of agriculture, and particularly relates to a dwarfing method of aquatic canna.
Background
The dwarfing technology of plants is very commonly applied to terrestrial plants, and particularly, the dwarfing technology of plants is used as a main variety for landscape cultivation, such as fruit tree bonsais, stump bonsais, flowers (such as cockscomb flowers) and the like. The rice, the staple food of the vast majority of people in China, is a very typical example of successful dwarfing. The rice straws of the rice in the fifth and sixty years of the last century are very long and high, almost more than fifty rice plants are laid down every year, the rice ears are as long as possible and are easy to fall off when the rice ears are heavier, and the rice straws are laid down and the rice seeds are mildewed and germinate in the ground, so that the yield and the quality of the rice seeds are seriously influenced. The height of the rice pole is almost 50-60% of the old rice pole, and almost no lodging occurs. Although not belonging to aquatic plants, rice grows in water for a lifetime very similar to that of aquatic plants.
At present, the dwarfing of terrestrial plants generally adopts the following methods: A. removing terminal buds, removing main branches and carrying out purposeful pruning; B. asexual propagation such as layering, cuttage, grafting and the like is used; C. manual intervention such as Qugan, girdling, button, needling, carving (such as daffodil), etc.; D. radiation treatment such as gamma ray treatment of narcissus bulb, cobalt 60 treatment of terrestrial canna; E. spraying, soaking root, mixing with soil, etc. with plant growth regulator, such as PP333, ethylene, chlormequat chloride, shapen, paclobutrazol, mepiquat chloride, B9; F. combines gene genetic technology and tissue culture technology.
Generally, terrestrial plants can adopt relatively more methods and are simpler to operate. The land plants grow on the ground, so that the operation is convenient, and the individual plant quantity is small; and the manual operation of the aquatic plants growing in water is very difficult. Therefore, the method A, B, C is not suitable for aquatic plants. Method F is the most advanced technique, but requires a high demand for a series of complete talent teams, laboratories and specialties. Usually done by institutional universities and research institutes. For example, the university of the Chinese sowthistle in seawater has developed the Chinese sowthistle strain with excellent performance in the whole seven years.
The dwarfing of the tape grass of the university of seawater is realized by combining the gene technology and the tissue culture technology. Is the only practical example of the successful dwarfing of aquatic plants.
To date, the aquatic plant dwarfing technology has not had a second successful example other than tape grass. Little research and attention has been directed to this work. As the application of aquatic plants is increased, the exposure problems are increased, such as lodging, breakage of plants on the floating island and even turning over or scattering of the whole floating island; the secondary pollution of large amount of plants, the overgrowth of submerged plants to the surface of water body seriously affects the water body landscape, the plants wither and die in winter every year, the too high pole is not beneficial to the production of pot seedlings and the like, so the call and the requirement for the energy improvement of the aquatic plants are stronger and stronger.
As for the potted seedling production of aquatic plants, China is in a very original state at present, and the aquatic plants are usually only moved from the ground to the culture pots for planting without any technical content and technical processing. With the improvement of living standard of people, the requirements on the quality, style and cleanliness of flowers are higher and higher, the original soil-culture flowers cannot meet the market demands, and the water-culture flowers are produced at the right moment. Hydroponic flowers are a model of scientific agriculture and high-efficiency agriculture in the world, and the development of hydroponic flowers is not well developed in some developed countries. The water culture flower production in China is in the beginning and rising period, and is one of the directions of flower development. At present, terrestrial plants have a plurality of varieties and types of water culture flowers. Has a certain market size and capacity. But the hydroponic flowers of aquatic plants are completely a blank. However, the water culture flower production of the aquatic plants also needs to adopt dwarfed varieties, otherwise, the products with beautiful shapes cannot be produced.

And the four series of paclobutrazol, mepiquat chloride, uniconazole and a reference meter are respectively sprayed and soaked in roots according to the concentration of the table, the total amount is 80 groups, and each group of ten pot seedlings is obtained.
Planting amount of seedlings in each pot: the amount of canna seedlings in each pot is 4 buds.
The requirements of seedling supply are as follows: the seedlings to be tested must be robust and disease-free, and the plant height and the thickness of stems and leaves among pots are consistent.
The requirements of the potting soil are as follows: the planting soil must be mixed evenly, and the soil consumption of each pot is equal.
Root soaking time: the control group was simultaneously soaked in water for 12 hours.
Spraying: spraying for the first time on the next day after planting; spraying for the second time 3 days after the first spraying; the third spraying is carried out 3 days after the second spraying.
② ground cultivation test
The concentration of the dwarfing agent used is the same as that of the potting test, and the root soaking method is also the same.
Preparing land cultivation land: selecting plots with the same conditions of illumination, soil quality and water quality, loosening and thinning soil on the surface of the land leveling layer, wherein the selected land requires a certain distance from other aquatic plants, and mutual interference is avoided.
Land area: approximately two square meters per test group were planted with 10 clusters per square meter with 4 shoots of canna plants per cluster. The plant selection criteria were the same as for the pot. The plants in each test group were substantially similar.
