Embodiment 1

[0006] Embodiment 1: A kind of efficient seedling raising method of eucalyptus, first adopt 600 times of liquid carbendazim to soak and sterilize for 10 minutes, wash the sterilized seeds with clear water, and then soak them in germination agent for 30 minutes; soak the soaked seeds Put the seeds in the sun to dry for 30 minutes; mix the magnetized seeds with wet sand and put them into the pit. The volume ratio of seeds and sand is 1:3, and the thickness of each layer is 5cm±0.5cm. The humidity of the sand can be held into a ball by hand. , out of the water, it is advisable to disperse as soon as you let go of your hands. Install it until it is about 20cm above the ground, cover it with 5cm river sand and 10cm thick straw, dig drainage ditches around it, and take out the seeds in March of the next year and sow directly.

[0007] In the above steps, the germination agent includes the following components in parts by weight: 55 parts of gibberellin, 50 parts of naphthaleneacetic ...

Abstract

The invention discloses an efficient seedling breeding method of Koelreuteria paniculata. Sterilizing is conducted through a 200-400-fold solution of carbendazim, sterilized seeds are cleaned with clean water and then placed in a germination accelerating agent to be soaked, the soaked seeds are placed in the sun to be aired for 20-30 min, and wet sand laminating and germination accelerating are conducted. The method has the advantages that the problem that Koelreuteria paniculata seeds are hard in peel and not prone to germination can be solved, the germination rate can be increased to 70% orabove from the original 30%, the seedling emergent time can be shortened to 10 days or shorter from the original 20 days, and the after-planting survival rate is high.

Description

technical field [0001] The invention relates to a seedling raising method, in particular to a method for raising eucalyptus seedlings with high efficiency. Background technique [0002] Luan tree is a kind of tree, up to 10 meters high, it grows in the calcium-based soil produced by weathering of limestone, it is not cold-resistant, it is only distributed in the lower reaches of the Yellow River Basin and Yangtze River Basin in China, it is rare in the north of the Hai River Basin, and it cannot grow In siliceous acidic laterite areas. The eucalyptus germinates late in spring and leaves early in autumn. Therefore, the annual growth period is short and the growth is slow. The shape of the tree is distorted and beautiful, and it is not very fruitful. However, the eucalyptus tree is dignified and neat, and its leaves, flowers, and fruits are all available for viewing. It is especially suitable for greening of tree-lined roads and sidewalks. The eucalyptus is mainly propagated...
