Embodiment Construction

[0018] In the Jinzhong area of ​​Shanxi, from late July to early August, mature fruits are harvested from a single plant of Xanthos sorbifolium, which has strong tree vigor, high yields year after year, full seed kernels, and strong resistance to diseases and insect pests. After drying, put it in a bag and store it in a dry and cool place.

[0019] Sieve and classify the seeds with sieves of 10mm, 8mm, and 6mm respectively. Seeds with a diameter greater than 10mm are classified as first-grade seeds, those with a diameter of 8-10mm are classified as second-grade seeds, and those with a diameter of 6-8mm are classified as third-grade seeds, and those with a diameter of less than 6mm are eliminated. seed.

[0020] Choose sandy loam or light clay loam plots with flat terrain, sheltered from the wind and sunny, deep soil, fertile soil, sufficient water, convenient transportation, and a pH value between 7 and 8 as the nursery. Before sowing, plow the nursery ground 30cm deep, apply...

Abstract

The present invention provides a seedling cultivation method of autumn sowing fruitage of shiny-leaved yellowhorn. The mature fruit is collected at an appropriate period and the seed is graded. An appropriate plot is selected as a plant nursery and is processed. The seed is sowed in autumn and the corresponding management is excellently executed in each period. The seedling cultivation method of autumn sowing fruitage of shiny-leaved yellowhorn according to the invention more accords with the natural course of seed growth and facilitates the healthy growth of seedling. The seedling generating time of autumn sowing of shiny-leaved yellowhorn is early for about 10 days than the seedling generating time of spring sowing. The plant height of autumn sowing of shiny-leaved yellowhorn is higher for 10cm than the height of seedling of spring sowing averagely. The diameter of principal root of autumn sowing of shiny-leaved yellowhorn is longer for 1.5mm than the diameter of principal root of spring sowing averagely. The survival rate of annual seedling is increased for 32% compared with the seedling which is germinated in natural condition. The plant height is higher for 6.3cm averagely, and the diameter of principal root is longer for 1.8mm averagely.

Description

technical field [0001] The invention belongs to the technical field of growing seedlings of fruit trees, and relates to a method for growing seedlings of sorbifolium sorbifolium, in particular to a method for growing seedlings of radix sorbifolium in autumn. Background technique [0002] Xinguo is an excellent woody oil tree species unique to northern my country, mainly distributed in Shanxi, Henan, Hebei, Inner Mongolia, Gansu and Ningxia, etc., known as "Northern Camellia oleifera". The oil content of the seeds of X. sorbifolium is 35-40%, and the oil content of the kernel is 72-75%, which is almost twice that of rapeseed. The content of unsaturated fatty acids in Xanthania sorbifolium oil reaches 94%, of which oleic acid accounts for about 57%, and linoleic acid accounts for about 37%, which has excellent health care functions. In addition, Xantho sorbifolium seeds can also be used to extract high-quality biodiesel, with a conversion rate of up to 95%. It has been listed...
