Stratification and germination acceleration method of red fruit holly

Abstract

The invention discloses a stratification and germination acceleration method of a red fruit holly, belonging to a plant production technology. The germination acceleration method comprises the following steps of: (1) from October to December, picking red fruit holly fruits which have russet peels, are completely ripe and have the capability of sprouting, taking out seeds from the fruits and drying the seeds at a shade place; (2) uniformly mixing the seeds with wet sand in a volume ratio of 1:3-5 and adding the mixture into a cloth bag; (3) deeply digging a pit with the depth of 60-70 cm at an outdoor shade and dry place, putting the cloth bag into the pit and covering sand for 20-30 cm, and then covering a layer of straws above the sand; and (4) sawing the seeds on a hotbed from October to December of the next year, namely enabling a part of seeds to expose white sprouts and germinate. According to the method provided by the invention, the germination percentage of the red fruit holly fruits is improved to 35% from nearly 0% in the condition of cultivating under a common seedling growing model and the germination acceleration effect is obvious. The method breaks through the difficulty of artificially cultivating the red fruit holly fruits and can better utilize the resource to garden beautification, ecological construction and medicinal materials; and the operation method is simple and practical and is easy to popularize.

Description

technical field [0001] The invention relates to a plant production technology, in particular to a method for accelerating germination of holly. Background technique [0002] Red holly ( Ilex corallina Franch) is an evergreen tree belonging to the holly family and the genus Ilex. It is an excellent garden beautification and garden ornamental tree species. Its tree shape is tall and can reach 20m. Buluo, which integrates appearance, leaves and fruits, is of great ornamental value and has always enjoyed a high reputation in the garden industry. However, due to the long dormancy of holly seeds, artificial propagation is difficult, which restricts the development of this fine variety. At present, the main body of use is to dig wild seedlings in the market (the natural germination rate of seeds is also very low under field conditions); rare artificial The holly holly seedlings of cultivation, therefore solving the holly holly seed germination problem is the practical difficulty...

Among them, the Chinese patent "Seed Biological Treatment Method" (application number: CN03152802) discloses a method of using biological methods to treat dormant seeds, but using natural organisms for treatment is too random and the procedure is complicated. It is difficult to use in practice, and large-scale seedling production cannot be carried out

In the prior art, in order to break the dormancy of seeds, the stratification method is often used, but the application of this method is very different in different plants, especially in the seeds that are almost in a completely dormant state, such as holly, which cannot be obtained by general stratification methods. higher germination rate
