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 sowing and seedling raising method of horsfieldia plants without injuring roots. The sowing and seedling raising method comprises the following steps of: (1) collecting seeds: collecting mature fruits on horsfieldia plant trees, or picking up fruits dropping in the same year of which the seeds are still intact; (2) treating the seeds: immediately treating the fruits after the fruits are harvested, and sowing the fruits during harvesting the fruits; (3) sowing the fruits and accelerating germination: A, preparing sand beds; B, sowing the fruits and accelerating germination; and C, performing management in the period of accelerating germination; (4) transplanting bud seedlings: A, compounding soil, and loading the compounded soil into sacks; B, digging up seedlings; and C, transplanting the seedlings; and (5) managing the seedlings in containers. According to the method disclosed by the invention, the purpose of promoting the growth of the nursery stocks without injuring roots is finally achieved mainly through the technical measures of accelerating germination on the sand beds, transplanting the bud seedlings with full roots, performing salt separation treatment on planting holes, raising the seedlings in large containers with light mediums, and the like. The method disclosed by the invention is used for cultivating horsfieldia nursery stocks and grandifoliate horsfieldia nursery stocks, the sowing germination rate can reach 94.8%, the transplanted survival rate is 100%, the nursery stocks are strong, the growing trend is uniform, and the nursery stocks can be transplanted from seedling nurseries within half a year. The success of the seedling raising technique has important significance on the resource protection, the scientific research, the development and the utilization of horsfieldia 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 HorsfieldiaWilld. is a Myristicaceae plant of the family Myristicaceae. There are three species distributed in China, namely Horsfieldiaamygdalina (Wall.) Warb., Horsfieldiakingii (Hook.f.) Warb. and Yunnan Fengnan. Horsfieldia prainii (King) Warburg, among them, Dayefengzhuinan is a species combined from Hainan Fengzhuinan, Diannan Fengzhuinii and Dayefengnan. come. 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 the content of 14-carbon fatty acids is ver...
