Embodiment 1

[0030] Before breeding, it is first necessary to prepare a softening agent for breaking shells, and prepare 10 g of dimethyl sulfoxide, 200 g of 0.2 wt % sodium hydroxide solution, and 3 g of raw materials of nano-titanium dioxide. The particle size of nano-titanium dioxide is about 200 nanometers. The preparation method is as follows:

[0031] Mix dimethyl sulfoxide and sodium hydroxide solution, stir evenly, add nano-titanium dioxide, and ultrasonically disperse for 10 minutes until the nano-titanium dioxide is evenly distributed in the solvent to obtain a shell-breaking softener.

[0032] The steps of sowing seedlings of beak walnut are as follows:

[0033] Seed collection: Select beak walnut fruits with full grains, fully mature, and no pests. Harvest when the exocarp is cracked or about to crack. Remove the exocarp from the harvested fruit. After cleaning the seeds, put them in a ventilated place indoors to dry in the shade. 120 worm eye seeds, about 1kg;

Embodiment 2

[0040] Before breeding, it is first necessary to prepare a softening agent for breaking shells, and prepare 20 g of dimethyl sulfoxide, 250 g of 0.1 wt % sodium hydroxide solution, and 5 g of raw materials of nano-titanium dioxide. The particle size of nano-titanium dioxide is about 200 nanometers. Its preparation method is identical with embodiment 1.

[0041] The step of beak walnut sowing seedling raising is identical with embodiment 1.

Embodiment 3

[0043] The preparation method of the shell softening agent is the same as in Example 1.

[0044] The steps of sowing seedlings of beak walnut are as follows:

[0045] Seed collection: Select beak walnut fruits with full grains, fully mature, and no pests. Harvest when the exocarp is cracked or about to crack. Remove the exocarp from the harvested fruit. After cleaning the seeds, put them in a ventilated place indoors to dry in the shade. 120 worm eye seeds, 1kg;

[0046] Enzyme treatment: add 0.6g laccase into 3L distilled water, stir well, add acetic acid to adjust pH=5.0 to make enzyme solution, then add dried seeds, at temperature 25-26℃, relative humidity 60-80 After soaking for 3 days in the environment of %, add 0.2g of soybean flour and stir evenly, continue soaking for 4 days, take out the seeds, and dry them in the shade for later use;

[0047] The remaining steps of softening the husk, soaking seeds, storing in sand, sowing, and seedling management are the same as ...

Abstract

The invention discloses an annamocarya sinensis seeding and seedling-raising method, and belongs to the technical field of forest cultivation. The method comprises the following steps of seed collection, namely selecting full and fully mature fruits, harvesting the fruits when epicarp cracks or is about to crack, removing the epicarp of the harvested fruits, cleaning seeds, and drying the seeds inthe shade in an indoor ventilated place; shell softening, namely soaking the cleaned seeds into an aqueous solution prepared from a shell breaking softener, irradiating for 5-6 hours by adopting ultraviolet rays of 280nm, cleaning, and drying in the shade for later use; seed soaking, namely placing the seeds after shell softening in clean water at the temperature of 25-30 DEG C to be soaked for 5-10 d, and changing water once every two days; sand storage, namely mixing the soaked seeds with wet sand, piling up a mixture to 50-90cm, inserting a hole in each pile every 0.5 m, placing in a ventilated and temperature-stable room or basement, and storing the seeds in sand for one month after film mulching; sowing; and seedling management. The problems of hard seed shells, difficulty in water absorption and low germination rate in seeding and seedling raising of annamocarya sinensis are solved, so that the purpose of protecting the annamocarya sinensis is achieved.

Description

technical field [0001] The invention relates to the technical field of tree cultivation, in particular to a method for sowing and raising seedlings of beaked walnuts. Background technique [0002] Beaked walnut (Annamocarya sinensis (Dode) Leroy) is a single species of Juglandaceae, a relict plant of the Tertiary ancient tropical zone, a deciduous tree, and a national second-class protected plant. The distribution area is narrow, mainly distributed in Guangxi, Guizhou, and Yunnan. Born in broad-leaved forests in valleys at an altitude of 200-1800m, it is also distributed in northern Vietnam. [0003] The beak walnut wood is light brown, with a glossy appearance, exquisite and beautiful patterns, uniform overall structure, and excellent wood material. The beak walnut seeds can be used to extract oil, the bark and exocarp can be used to extract tannins, and the shell can be used to make activated carbon. Therefore, the beak walnut It has high economic value and use value. Be...
