A kind of root cutting seedling raising method of fish tree

Abstract

The invention provides a method for growing seedlings by root cuttings of fish trees, comprising the following steps: (1) selecting seed roots according to the germination ability and the abundance of seed roots; (2) intercepting and disinfecting the seed roots; (3) illuminating the root cuttings, Water, temperature control and substrate ratio; (4) type, concentration and time of hormone treatment; (5) cutting method and water management after cutting; (6) root division and seedling formation. The present invention selects the root segment with fibrous roots on the edge of the root crown of the fish tree as the seed root of the root cutting, which does not affect the crown shape of the mother tree, is easy to operate, and has a large reproduction coefficient; the thickness of the seed root suitable for the root cutting, the cutting method, the ratio of the root cutting matrix, and Hormone type, hormone concentration and hormone treatment time shorten the bud germination time, effectively increase the rate of bud germination, rooting rate and seedling rate, realize the rapid seedling growth of Yumu in a short period of time, and provide resources for the development and protection of Yumu. Foundation.

Description

technical field [0001] The invention relates to a method for growing seedlings of fish trees, in particular to a method for raising seedlings of fish trees by root cuttings. Background technique [0002] Cratevareligiosa G. Forster is a small perennial deciduous tree of the genus Crateva in the Capparidaceae family. It is distributed in Taiwan, Guangdong, Guangxi, and Sichuan in my country. It is an excellent native flowering tree. Its wood can be used for musical instruments and detailed crafts. The material is light but hard. Fishermen in Taiwan and Ryukyu use it to carve small fish into bait, and it is poisonous to fish, so it is called "fish wood". The euclid extracted from the skin has anti-inflammatory, antibacterial, anti-tumor, diuretic, blood pressure-lowering and cholesterol-lowering effects, and the peel has certain anti-fungal effects; the fruit contains alkaloids, which can be used as adhesives, and the peel can be used as dyes. It can be seen that Yumu is an e...

Problems solved by technology

Studies have shown that the in vitro culture of plants is faster than other propagation methods with a reproduction cycle of more than one year. However, it is time-consuming to establish a sterile system in the early stage of in vitro culture. Breeding speed is not dominant

We found in the preliminary research in the early stage that the stem cuttings of Yumu have a low survival rate, and only one seedling can be cultivated at each segment, while the root cuttings are prone to adventitious buds, with a high survival rate, and each segment can produce many buds for reproduction. It is an ideal propagation material, and it is expected to improve the problem of low speed in the short-term in vitro propagation of fish wood
