Introduction and cultivation method of acrocarpus fraxinifolius plant

Abstract

The invention discloses an introduction and cultivation method of an acrocarpus fraxinifolius plant. The introduction and cultivation method comprises the steps of: placing picked mature seeds of the acrocarpus fraxinifolius plant at the temperature of 0-10 DEG C and storing for 30-150 days or placing the picked mature seeds of the acrocarpus fraxinifolius plant at a natural temperature of an acrocarpus fraxinifolius plant growing mountain for 30-150 days, or storing the picked mature seeds of the acrocarpus fraxinifolius plant at room temperature in a drying manner, and soaking the mature seeds with a gibberellin solution with a concentration of 800-1000mg / L for 24-48h before sowing to obtain preprocessed seeds; and carrying out direct seeding on the processed seeds or sowing in a pot, carrying out sprout stock transplanting when the seeds germinate and sprout stocks grow to 1-3cm and generate main leaves, placing the transplanted seedlings in a sunshade frame, covering the sunshade frame by using a sunshade net, wherein soil for direct seeding and transplanting is wet, fertile and well-drained soil, the growing environment is a cool and wet environment in summer, and water and fertilizer supply are met through watering and fertilizing. The mature seeds are processed according to the introduction and cultivation method disclosed by the invention, the germination rate of the seeds of the acrocarpus fraxinifolius plant reach above 90 percent, the seedlings emerge orderly, and the quality of the sprouts of the acrocarpus fraxinifolius plant is effectively ensured.

Description

Technical field: [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for introducing and cultivating acrocarp plants.

Problems solved by technology

Under natural conditions, when the seeds mature, it is in autumn when there is little rain, and it is easy to lose water and fail to complete the post-ripening process and lose vitality. This is an important reason for the difficulty in natural regeneration of this species and the difficulty in introducing and cultivating it.
