Problems solved by technology

Live broadcasting on land, with many weeds in the field, poor moisture retention capacity, high field management costs, and low seedling rate
If the seeding is too deep, the emergence rate is low, and if the seeding is too shallow, the germinated seeds are prone to drought or seedling death

Embodiment 1

[0013] A kind of Mongolian almond seed low-temperature stratification accelerating germination method for raising seedlings of the present embodiment is carried out at Hexi University Teaching and Experimental Base, comprising the following steps:

[0014] 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 by picking or knocking. , collect uniform, plump, pest-free fruits, and complete the seed collection process;

[0015] S2. Seed cleaning and selection: Remove the mesocarp and impurities from the collected Mongolian almond seeds, dry them indoors in the shade, 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 material.

[0016] S3, post-ripening tre...

Embodiment 2

[0028] A kind of Mongolian almond seed low-temperature stratification accelerating germination seedling raising method of present embodiment is carried out in Gansu Province Zhangye City Ganzhou District Forestry Bureau Hongshawo Forest Farm Seedling Base, comprising the following steps:

[0029] 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 by picking or knocking. , collect uniform, plump, pest-free fruits, and complete the seed collection process;

[0030] 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;

[0031] S3, post-ripening treatment of seeds: treat the seeds treated with S2 at 35° C. for 96 hours to complete post-ripenin...

Embodiment 3

[0041] In the present embodiment, a kind of Mongolian almond seed low-temperature stratification accelerating germination seedling raising method is carried out at the state-run Wuquan forest farm seedling raising base in Linze County, Zhangye City, Gansu Province, and the steps are the same as example 1.

[0042] However, in the embodiment, step S5 is to uniformly mix S4 with the seed S3 after ripening treatment at a rate of 5:1 (v / v), put it into a woven bag, and put it into a 2-5°C low-temperature refrigerator for moisturizing treatment for 15 days. Place it indoors (15°C) for 2-3 days to make the shell of the seeds crack or germinate "lubai";

[0043] In step S7, combined with deep plowing in autumn, apply 3 tons of decomposed sheep manure, superphosphate 25Kg / mu, winter irrigation after winter, combined with seed fertilizer application in spring, spray "trifluralin" herbicide on the soil, and use "carbofuran" The configured bran poison bait 5Kg is sprinkled on the soil to...

Abstract

The invention discloses a low-temperature stacking, germination-accelerating and seedling-growing method for Prunus mongolica Maxim seeds. The method comprises the following steps: seed collection, cleaning and careful selection of the seeds, after-ripening treatment of the seeds, and stacking and germination-accelerating treatment. The seeds treated by the method have the advantages of fast seedling emergence speed and high emergence rate; and the method has the advantages of simplicity, good seedling quality, low cost of seedling growth, high outplanting rate of the seedlings, and effectiveness in control of nursery field weeds.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a method for accelerating germination and raising seedlings of Mongolian almond seeds by low-temperature stratification. Background technique [0002] Mongolian almond (Prunus mongolica Maxim) is a perennial deciduous shrub of the genus Prunus L. in the Rosaceae family. Mountains, Jiufeng Mountains and western Yinshan Mountains, Helan Mountains in Ningxia, Tengger Desert and Altai in Xinjiang, distributed in Longshou Mountain, central Hexi Corridor and northern edge of Qilian Mountains in Gansu; also distributed in Mongolia and Kazakhstan. As a unique xeric deciduous shrub in the Gobi Desert in central Asia, it is also a good tree species for saline-alkali land management and prevention of soil erosion. It is a landscape plant and soil and water conservation plant with high ecological value in the cold, arid and desert areas of Northwest China. At the same time, seed kernels...
