Problems solved by technology

Harvest when the fruit is ripe in autumn, dry and remove the shell in time, but the seed coat is hard and difficult to permeate, if it is not treated, it will often not germinate in the second spring sowing; because the emergence rate of eucalyptus seeds is low, the amount of seeds used is large, and the sowing amount reaches 30. -40kg / mu

Embodiment 1

[0020] A seedling cultivation method of eucalyptus, comprising the following steps:

[0021] Step 1, harvesting of seeds: the fruit of the eucalyptus tree matures from September to October. Select an excellent single plant that grows well, has a straight trunk, a wide crown, and is in the prime of life as the mother tree for seed collection. When the fruit is reddish brown or orange and yellow The capsules are collected when they have not cracked, otherwise they will fall off by themselves. But it should not be picked too early, otherwise the seed germination rate will be low.

[0022] Step 2, processing and storage of seeds: After collecting the fruits, remove the pericarp and fruit stalks, dry them in the sun or spread them out in the shade, and after the capsules are cracked, beat and thresh, and use the screening method to clean the seeds. Soak the obtained black seeds in 17% hydrogen peroxide solution for 1 min for disinfection, take them out, clean them, soak them in 40...

Abstract

The invention discloses a Koelreuteria paniculata seedling culture method. The method includes: selecting excellent single Koelreuteria paniculata which is good in growth, straight in trunk, wide in crown and in a robust stage as the seed collecting mother tree, and collecting fruits when the fruits are red brown or orange and capsules do not crack; removing the pericarps and stems of the collected fruits, beating for threshing after capsule cracking, screening clean seeds, sterilizing the obtained seeds, placing the sterilized seeds in a germination accelerating agent, taking out, and storingin wet sand; taking out the stored seeds, subjecting the seeds to germination accelerating treatment, sowing the seeds in a prepared seed bed, and performing water and fertilizer management, diseaseand pest control and thinning pruning in the later period. The method has the advantages that the Koelreuteria paniculata seeds are preprocessed, emergence rate can be increased greatly, and seed useamount can be lowered greatly.

Description

technical field [0001] The invention belongs to the technical field of forestry planting, and in particular relates to a method for raising seedlings of eucalyptus. Background technique [0002] The eucalyptus is a tree species of the genus Euania in the family Sapindaceae, with dense branches and leaves and a beautiful tree shape.
