Embodiment 1

[0029] The present embodiment improves the method for caragana seed germination and seedling rapid growth, comprises the following steps:

[0030] 1. Seed treatment

[0031] Disinfection treatment: the caragana seeds were washed 3 times with an alcohol solution with a volume concentration of 50%, for 6 minutes each time, then washed 4 times with a sodium hypochlorite solution with a mass concentration of 6%, for 4 minutes each time, and then rinsed with distilled water for 4 times , wash 3min each time.

[0032] Soaking in germanium-containing solution: soak the sterilized caragana seeds in a germanium-containing solution with a concentration of 10 μmol / L at 25° C. for 24 hours. In this embodiment, the germanium-containing solution is an organic germanium solution Ge-123.

[0033] 2. Seed Germination

[0034] The soaked Caragana seeds were cultured in an incubator under the conditions of 50% humidity, 1000lx light and 25°C temperature. The light time was 8 hours a day, and ...

Embodiment 2

[0037] The difference between the method of improving Caragana seed germination and seedling growth in this example and Example 1 is that the concentration of the organic germanium solution Ge-123 in this example is 20 μmol / L, and other conditions are the same.

Embodiment 3

[0039] The difference between the method for improving the germination of Caragana seeds and the rapid growth of seedlings in this example and Example 1 is that the concentration of the organic germanium solution Ge-123 in this example is 30 μmol / L, and other conditions are the same.

Abstract

The invention discloses a method for improving seed germinating and seedling quick growth of caragana microphylla. The method comprises the following steps of seed treatment: soaking disinfected seeds of caragana microphylla into a germanium-containing solution with concentration of 10 to 30mumol / L at the temperature of 22 to 28 DEG C for 20 to 25h; seed germinating: culturing the soaked seeds of caragana microphylla in a culture box at the humidity of 45 to 55%, illumination of 500 to 2000lx, and temperature of 23 to 26 DEG C, wherein the lighting time is 7.5 to 8.5h each day, and dark culture is performed in the other time. The method for improving seed germinating and seedling quick growth of caragana microphylla has the advantages that the method is simple, the implementing is easy, the cost is low, and the operation is simple; the germinating rate of the treated seeds is obviously improved, and the growth of seedlings is accelerated.

Description

technical field [0001] The invention relates to the technical field of plant seed cultivation, in particular to a method for improving the germination of caragana seeds and the rapid growth of seedlings. Background technique [0002] Caragana Korshinskii Kom (Caragana Korshinskii Kom) is a large perennial deciduous shrub of the family Caragana genus, mainly distributed in Inner Mongolia, Shaanxi, Ningxia, Gansu and other places in Northwest China. The roots have root nodules, are resistant to drought and barrenness, and are the main native species for afforestation and vegetation restoration in Northwest China. Lime branches, leaves, flowers, fruits, and seeds are rich in nutrients and are good forage. The branches contain oil, so they can be burnt dry and wet, so they are good firewood materials. However, there are some difficulties in the seed germination and seedling growth period of Caragana japonica, such as low germination rate, irregular germination, slow growth of ...
