Embodiment 1

[0014] Example 1: Air-dried after seed picking in October 2008, mixed evenly in wet sand volume 1:3 in mid-November, placed under the condition of daily variable temperature 25 (± 7) ℃ to mid-January 2009, then transferred to daily variable temperature 0 (±7)°C to mid-February, and to mid-March at a daily temperature change of 10(±5)°C. In mid-March 2009, the CaCl 2 Seed soaking treatment with GA, a total of 11 treatments, soaking seeds for 24 hours. There were 5 pots for each treatment, and 20 seeds were sown in each pot. After the emergence rate was investigated in early April, 10 seedlings were established in each pot, and drought treatment and physiological index measurements were carried out in mid-May. Drought treatment: After pouring sufficient water, stop watering, gradually dry, and take samples for measurement on the 3rd, 6th, and 9th day respectively.

[0015] Using MINITAB statistical analysis software to adopt GA and CaCl 2 Two-factor five-level regression ort...

Abstract

The invention relates to technology for treating cultivation seeds of fraxinus mandshurica drought-resisting nursery stocks, and relates to seed treatment technology. Treatment solution, namely mixed aqueous solution, of fraxinus mandshurica seed is prepared by dissolving analytically pure gibberellin into a small amount of 95 percent alcohol, mixing the dissolved analytically pure gibberellin and anhydrous CaCl2. The concentration of GA is 300mg / L, the concentration of CaCl2 is 1.4 percent. After being treated by the treatment solution of the fraxinus mandshurica seed, fraxinus mandshurica seeds sprout and germinate normally; and fraxinus mandshurica seedlings are little damaged and grow better under the drought condition; therefore, the drought resistance capacity of the fraxinus mandshurica seedlings can be improved by immersing the seeds in the treatment solution of the fraxinus mandshurica seed before seeding.

Description

technical field [0001] The invention relates to a seed treatment technology, in particular to a seed treatment technology for cultivating drought-resistant seedlings of Mandshurica mandshurica. Background technique [0002] Mandshurica mandshurica is one of the three precious hard broad-leaved tree species in Northeast China, one of the important companion tree species of broad-leaved Korean pine forests in the eastern mountainous areas of Northeast China, and one of the main tree species in secondary forest areas. High elasticity, straight texture, is a precious material. At present, foreign researches on Fraxinus mandshurica are mostly concentrated in Japan and South Korea, and the research content involves physiology, ecology, pathology, wood science, etc.; domestic reports on it can be summarized into five categories, including site afforestation, physiological ecology, and seed gardens Construction and cloning, material properties, embryology, etc. At present, the res...
