Embodiment 1

[0035] 1. Seed collection and seed treatment: The seed collection time was at the end of March 2014. The seed collection objects were: Hainan Fengchuinan (now known as Dayefengchuinan) seeds. It is collected from the Tropical Forestry Experimental Center of the Chinese Academy of Forestry in Pingxiang, Guangxi, and the mother tree is artificially planted. The seeds are all collected from a single plant. The fruit is yellow-green but not cracked when harvested. After being brought back, it is spread out and placed in a ventilated place. After 7 days, the skin becomes soft and cracks.

[0036] 2. Seed germination

[0037] Remove the weeds in the sand bed on April 10, level the bed surface after loosening the soil, compact it slightly, and disinfect it with a potassium permanganate solution with a mass concentration of 0.5%. On the afternoon of April 11, drench the sand bed with clear water. The sowing treatment was set to remove the pericarp and aril for the seeds of Clamwood ...

Embodiment 2

[0049] 1. Seed collection and seed treatment: The time for seed collection was mid-April 2015. The seeds of Fengchuinan and Dayefengchuinan were collected from Yunnan Xishuangbanna Botanical Garden. The mother tree was artificially planted, and the seed collection method was single plant. The fruits have been cracked when harvested, and after being brought back, they are spread out and placed in a ventilated place for immediate sowing.

[0050] 2. Seed germination

[0051] Remove the weeds in the sand bed on April 21, level the bed surface after loosening the soil, compact it slightly, and disinfect it with a potassium permanganate solution with a mass concentration of 0.5%. After 4 pm on April 22, drench the sand bed with clean water. After the sand bed is ready, the seeds are treated. First, remove the peel and aril, wash with water, soak the seeds in 500 mg / L potassium permanganate solution for 10 minutes, and remove them. When sowing, open a small ditch along the width o...

Abstract

The invention discloses a method for sowing and raising seedlings of plants of the genus Phoebe without root damage, comprising the following steps: (1) collecting seeds: collecting ripe fruits on trees of the genus Phoebe or picking up the fallen fruit of the year when the seeds are still intact; (2) the seeds Treatment: The fruit should be processed immediately after harvesting and sowed as it is harvested; (3) Sowing germination: ①Sand bed preparation, ②Sowing germination, ③Management during germination; (4) Sprout transplanting: ①Bag with soil, ②Lifting, ③Transplanting; (5) Container seedling management. The method of the invention mainly adopts technical measures such as germination acceleration in a sand bed, full-root transplantation of sprouts, salt separation treatment in planting holes, seedling cultivation in a large container with light substrates, etc., so as to finally achieve the purpose of not damaging roots and promoting growth of seedlings. By applying the method of the present invention to cultivate Phoebe nannuum and Phoebe big-leaf Phoebe seedlings, the seeding germination rate can reach 94.8%, and the survival rate after transplanting is 100%. The success of this seedling raising technology is of great significance to the resource protection, scientific research and development and utilization of Phoebe species.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and relates to a sowing and propagation technology of nationally protected plants and special oil tree species, specifically a method for sowing and raising seedlings of plants of the genus Phoebe without damaging roots. Background technique [0002] The genus Horsfieldia Willd. is a Myristicaceae plant of the family Myristicaceae. There are three species distributed in China, namely Horsfieldia amygdalina (Wall.) Warb., Horsfieldiakingii (Hook.f.) Warb. and Horsfieldia prainii (King) Warburg, among them, Dayefengnan is a species combined from Hainan Fengzhui, Nannan Fengzhui and Dayefengnan, and Yunnan Fengzhuinia is composed of Qinyefeng Chui Nan changed his name. Existing studies have shown that the seeds of the genus Phoebe have a very high oil content (about 34.06-56.18%), and the total fatty acid content of less than 20 carbons in the total fatty acids is more than 90%, and...
