Problems solved by technology

[0003] Mongolian almond seedlings have poor root anti-oxidation ability, low vigor when transplanted directly, and slow seedlings when transplanted into adult plants; plants bloom early, are prone to flowering and fruit drop in late spring, and the number of mature seeds is small; mature seeds are vulnerable to rodents after rain falls. , Rabbits and other rodents eat and lose their vitality; Mongolian almond seeds have shallow after-ripening dormancy and firmness, and the germinated Mongolian almond seeds have poor drought resistance, cold resistance, and salt tolerance, and the mortality of seedlings under high temperature conditions is high. Obstacles to breeding of seedlings, all of which lead to the endangerment of the species and obstacles to reproduction

Embodiment 1

[0027] A container seedling raising method of rare woody oil crop Mongolian almond, carried out in the teaching and experiment base of Hexi University in mid-August, including the following steps:

[0028] S1. Seed collection: From mid-July to early September, in the seed collection nursery or wild Mongolian almond distribution area, select the mother plant with strong tree vigor, dense fruit, and no pests and diseases as the seed collection plant, and pick it up by picking or tapping , collect uniform, plump, pest-free fruits, and complete the seed collection process;

[0029] S2. Seed cleaning and selection: Remove the mesocarp and impurities from the collected Mongolian almond seeds, dry them in the shade indoors, and remove empty, dull, diseased, and weak seeds from the seed batch by liquid specific gravity method, leaving them plump and neat , robust, high-viability seeds as sowing materials;

[0030] S3, post-ripening treatment of seeds: Treat the seeds treated in S2 at...

Embodiment 2

[0042] A container seedling raising method of mongolic almond seeds, a rare woody oil crop, was carried out in mid-August at the seedling raising base of Hongshawo Forest Farm, Ganzhou District Forestry Bureau, Zhangye City, Gansu Province, including the following steps:

[0043] S1. Seed collection: From mid-July to early September, in the seed collection nursery or wild Mongolian almond distribution area, select the mother plant with strong tree vigor, dense fruit, and no pests and diseases as the seed collection plant, and pick it up by picking or tapping , collect uniform, plump, pest-free fruits, and complete the seed collection process;

[0044] S2. Seed cleaning and selection: Remove the mesocarp and impurities from the collected Mongolian almond seeds, and select plump, neat, robust, and high-viability seeds as sowing materials;

[0045] S3, post-ripening treatment of seeds: Expose the seeds treated by S2 on a drying mat for 5-7 days in summer, so as to complete post-r...

Embodiment 3

[0055] A seedling raising method of mongolian almond seeds, a rare woody oil crop, is carried out in the seedling greenhouse of the state-owned Wuquan Forest Farm in Linze County, Zhangye City, Gansu Province in the middle and early November, and the steps are the same as those in Example 1.

[0056] However, in the embodiment, step S3 is to treat the seeds treated in S2 at 35° C. for 96 hours, so that the seeds are ripened and the vigor is improved;

[0057] In the embodiment, step S5 is to uniformly mix the river sand treated in S4 with the post-cooked seeds in S3 at a ratio of 5:1 (v / v), put it into a ziplock bag and punch holes, and put it in a low-temperature refrigerator at 2-5°C Moisturizing treatment for 8 days, and then placed indoors (20°C) for 2-3 days, so that the husks of the seeds are cracked or germinated "white", and the endocarp of the seeds with uncracked husks is mechanically removed;

[0058] Substrate preparation in step S7: crush farmland Changshu farmlan...

Abstract

The invention discloses a seed container seedling raising method of rare woody oil crop Mongolia almonds. The method comprises the steps of seed collection, seed selection, after-ripening treatment onseeds, stratification, endocarp removal and the like. By means of the method, the emergence speed is high, the emergence rate is high, the seeds are saved, the method is simple and convenient, materials are obtained locally, the quality of cultured seedlings is good, the seedling raising cost is low, the field planting survival rate is high, and the method is a good method for saving and expanding propagation of Mongolian almonds.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a method for growing seedlings of mongolian almond seeds in containers of rare woody oil crops. Background technique [0002] Prunus mongolica Maxim is a perennial deciduous shrub of the genus Prunus L. in the Rosaceae family. It is a landscape plant and soil and water conservation plant in the cold, dry and desert areas of Northwest China with high ecological value. At the same time, seed kernels can be used as medicine instead of "Yu Liren", which can moisten the intestines and relieve constipation, relieve phlegm and cough, diuresis, and mainly treat symptoms such as dry stool, edema, beriberi, etc. It is a traditional Chinese medicinal material with important economic and medicinal value. Mongolian almond kernels and kernel oil are both edible, and the oil content is about 40%. However, long-term human disturbance and livestock grazing activities have caused a sharp decline ...
