Problems solved by technology

[0003] The original seed propagation of Acer palmatum usually adopts the method of sowing and raising seedlings. After the seeds are harvested in October, they need to be stratified in wet sand until February to March of the following year before sowing. During the stratification process, regular inspection and cleaning of the seeds are required. The process is cumbersome , and it can only be unearthed 25-30 days after sowing, the germination rate can only reach 80%, and the seedling cycle is too long, so that the seedling efficiency of Acer palmatum is low

Embodiment 1

[0019] A method for sowing and raising seedlings of Acer palmatum includes the following steps:

[0020] Step 1. Choose a 15-20 year old, robust, well-grown mother tree with a neat crown and no pests and diseases. Pick the mature fruits from September to October, remove the seed wings, and get clean seeds. Store in a sealed room at a temperature of 15 -20℃ and full of CO 2 atmosphere.

[0021] Step 2. Before spring sowing, take out the stored seeds, soak them in an oxalic acid solution, the concentration of the oxalic acid solution is 20%, and the soaking conditions are 45°C for 6 hours, and then wash them after removal.

[0022] Step 3. Dry the washed seeds at a low temperature of 50°C and then soak them in a soaking solution. The soaking solution is made by adding 3 mg of indole acetic acid, 4 mg of 6-BA, and 40 mg of citric acid to 1L of the moso bamboo soil extract. The moso bamboo soil extract is obtained by immersing the moso bamboo garden soil at 100g / L in distilled water for...

[0028] A method for sowing and raising seedlings of Acer palmatum includes the following steps:

[0029] Step 1. Choose a 15-20 year old, robust, well-grown mother tree with a neat crown and no pests and diseases. Pick the mature fruits from September to October, remove the seed wings, and get clean seeds. Store in a sealed room at a temperature of 15 -20℃ and full of CO 2 atmosphere.

[0030] Step 2. Before spring sowing, take out the stored seeds, soak them in an oxalic acid solution, the concentration of the oxalic acid solution is 25%, and the soaking conditions are 45°C for 4 hours, and then wash them after taking them out.

[0031] Step 3. Dry the washed seeds at a low temperature at 50°C and soak them in a soaking solution, which is made by adding 4 mg of indole acetic acid, 3 mg of 6-BA, and 30 mg of citric acid to 1L of the moso bamboo soil extract. The moso bamboo soil extract is obtained by immersing the moso bamboo garden soil at 100g / L in distilled water for 48 hours an...

[0037] A method for sowing and raising seedlings of Acer palmatum includes the following steps:

[0038] Step 1. Choose a 15-20 year old, robust, well-grown mother tree with a neat crown and no pests and diseases. Pick the mature fruits from September to October, remove the seed wings, and get clean seeds. Store in a sealed room at a temperature of 15 -20℃ and full of CO 2 atmosphere.

[0039] Step 2. Before spring sowing, take out the stored seeds, soak them in an oxalic acid solution, the concentration of the oxalic acid solution is 23%, and the soaking conditions are 45°C for 6 hours, and then wash them after taking them out.

[0040] Step 3: Dry the washed seeds at a low temperature of 50°C and soak them in a soaking solution, which is made by adding 6 mg of indole acetic acid, 3 mg of 6-BA, and 20 mg of citric acid to 1L of the moso bamboo soil extract. The moso bamboo soil extract is obtained by immersing the moso bamboo garden soil at 100g / L in distilled water for 48 hours an...

Abstract

The invention discloses a sowing and seedling raising method of acer palmatum. The method comprises the following steps: selecting mother trees of 15-20 years old, collecting mature fruits as seeds from September to October, removing seed wings, and carrying out indoor sealing storage on the seeds; before spring sowing, placing the stored seeds in an oxalic acid solution for soaking, taking out the seeds and carrying out cleaning, carrying out low-temperature drying at a temperature of 50 DEG C, then soaking the seeds in a soaking solution, and carrying out freezing-microwave circulation germination treatment on the treated seeds to obtain germination accelerated seeds; carrying out deep ploughing on sandy loam, applying a decomposed rapeseed cake fertilizer mixed with yellow soil, diggingseeding ditches in a leveled seedling bed, carrying out bottom water irrigation, then uniformly sowing the germination accelerated seeds into the ditches, and covering the seeds with sandy soil; andcarrying out coverage with a sunshade net after bud seedlings come up, and carrying out water and fertilizer management. According to the method disclosed by the invention, ultrasonic soaking is combined with the freezing-microwave circulation treatment, damage to structure of seed coats is accelerated, dormancy of the seeds is broken, the time for seed germination acceleration and the time for sprouting and coming up after seed sowing are shortened, conventional long-time accumulation of wet sand is avoided, and seedling raising efficiency of acer palmatum in spring is obviously improved.

Description

Technical field [0001] The invention belongs to the technical field of plant cultivation, and specifically relates to a method for sowing and raising seedlings of Acer palmatum. Background technique [0002] Acer palmatum ( Acer Palmatum ), alias Bu Yafeng, is a genus of Aceraceae. It is native to the Yangtze River basin of China, and is also distributed in Japan and the Korean Peninsula. Small deciduous tree, about 8m high, with dark gray bark and blue-green young branches. Leaves opposite, palmately deeply divided, 5-7 lobes, base truncated, lobes oval or lanceolate, apex or tail sharp, irregularly serrated, tender leaves densely pilose . The leaves are red first and then green in spring and turn red in autumn. Corymbs inflorescences grow at the top, bloom after the leaves, and the flowers are purple-red. The samara is purplish red at first and brownish-yellow when mature, with two wings spreading out into obtuse angles. Flowering in May, fruit ripening period from Septe...
