Problems solved by technology

[0002] Acer palmatum, also known as maple palmatum, has an umbrella-shaped crown and elegant posture. It can be planted as a sidewalk and ornamental tree. After the monthly seeds are harvested, they need to be stratified in wet sand until February to March of the following year before they can be sown. During the stratification process, the seeds must be checked and cleaned regularly. The process is cumbersome and can only be unearthed 25 to 30 days after sowing. About 85%, the seedling cycle is too long, so that the seedling efficiency of Acer palmatum is significantly reduced

Embodiment 1

[0019] A method for raising seedlings in spring of Acer palmatum seeds, comprising the following steps:

[0020] (1) Soaking: Before sowing in spring, soak the dried seeds in sodium hydroxide solution for 4 hours, with a mass concentration of 1.1%, to speed up the destruction of the seed coat structure, promote the immersion of nutrients and water from the outside, inhibit the activity of dormant substances, and accelerate the growth of seeds. Germinate, wash, soak the seeds;

[0021] (2) Fermentation: Put the soaked seeds in the lactic acid bacteria fermentation broth, ferment at 41°C for 25 hours, adjust the pH of the seeds, promote the immersion of a large number of metabolites produced by fermentation into the seed coat, break the dormancy of the seeds, promote the growth of the germ, and shorten the germination and aging of the seeds. Germinate and unearth time after sowing, filter to obtain fermented seeds and fermentation liquid; for the lactic acid bacteria fermentatio...

Embodiment 2

[0027] A method for raising seedlings in spring of Acer palmatum seeds, comprising the following steps:

[0028] (1) Soaking: Before sowing in spring, soak the dried seeds in sodium hydroxide solution for 4 hours, with a mass concentration of 1.2%, to speed up the destruction of the seed coat structure, promote the immersion of nutrients and water from the outside, inhibit the activity of dormant substances, and accelerate the growth of seeds. Germinate, wash, soak the seeds;

[0029] (2) Fermentation: Put the soaked seeds in the lactic acid bacteria fermentation liquid, ferment at 42°C for 28 hours, adjust the pH of the seeds, promote the infiltration of a large number of metabolites produced by fermentation into the seed coat, break the dormancy of the seeds, promote the growth of the germ, and shorten the germination and Germinate and unearth time after sowing, filter to obtain fermented seeds and fermentation liquid; for the lactic acid bacteria fermentation liquid, insert...

Embodiment 3

[0035] A method for raising seedlings in spring of Acer palmatum seeds, comprising the following steps:

[0036] (1) Soaking: Before sowing in spring, soak the dried seeds in sodium hydroxide solution for 5 hours, with a mass concentration of 1.3%, to speed up the destruction of the seed coat structure, promote the immersion of nutrients and water from the outside, inhibit the activity of dormant substances, and accelerate the growth of seeds. Germinate, wash, soak the seeds;

[0037] (2) Fermentation: Put the soaked seeds in the lactic acid bacteria fermentation broth, ferment at 43°C for 30 hours, adjust the pH of the seeds, promote the immersion of a large number of metabolites produced by fermentation into the seed coat, break the dormancy of the seeds, promote the growth of the germ, and shorten the germination and germination of the seeds. Germinate and unearth time after sowing, filter to obtain fermented seeds and fermentation liquid; for the lactic acid bacteria ferme...

Abstract

The invention mainly relates to the technical field of planting and discloses a spring seedling cultivation method for acer palmatum seeds. The method includes soaking, fermenting, freezing, germination accelerating, sowing and managing. The method is simple and convenient to operate, traditional long-term accumulation of wet sand is avoided, germination accelerating time is shortened to 4-5 days, germination is realized 7-9 days after sowing, the germination rate reaches 94.7%, and spring seedling cultivation efficiency of acer palmatum is evidently improved. Dry seeds are soaked in sodium hydroxide solution before sowing so as to accelerate damaging of seed coat structures, promote infiltration of external nutrients and moisture, inhibit dormant substance activity and accelerate seed germination. The soaked seeds are added into lactobacillus fermentation liquid to realize seed pH adjustment through long-time fermentation of lactobacillus, infiltration of a great quantity of metabolites generated by fermentation into seed coats is promoted, seed dormancy is broken, germ growth is promoted, and seed germination accelerating and after-sowing germination time can be shortened.

Description

technical field [0001] The invention mainly relates to the technical field of planting, in particular to a method for raising seedlings of Acer palmatum seeds in spring. Background technique [0002] Acer palmatum, also known as maple palmatum, has an umbrella-shaped crown and elegant posture. It can be planted as a sidewalk and ornamental tree. After the monthly seeds are harvested, they need to be stratified in wet sand until February to March of the following year before they can be sown. During the stratification process, the seeds must be checked and cleaned regularly. The process is cumbersome and can only be unearthed 25 to 30 days after sowing. About 85%, the seedling raising period is too long, so that the seedling raising efficiency of Acer palmatum is obviously reduced. Contents of the invention [0003] In order to make up for the defects of the prior art, the purpose of the present invention is to provide a method for raising seedlings of Acer palmatum seeds ...
