Problems solved by technology

Sandalwood is mainly propagated by seeds, but the seeds of the sandalwood tree have a certain dormant period. The harvested seeds are stored for 1 to 2 months. About one month after sowing, only a few sporadic seeds germinate, and the germination period can last up to one year. More than, germinate one after another, this brings great difficulty to management work, simultaneously, because the seed shell of sandalwood tree seed is hard, the permeability of moisture is poor, and causes certain mechanical stress, influences the germination of seed, and the germination of sandalwood tree seed The germination rate is very low, and if the seeds are not treated, the germination rate is less than 30%. In order to solve the problems of long germination time, irregular germination and low germination rate of sandalwood seeds, the reported methods for processing seeds have the following: 1. machinery Removing the seed husk can germinate early after sowing, but the germination period is as long as 270 days or more, so the method of dehulling cannot break the dormancy of sandalwood seeds, and manual dehulling is time-consuming, labor-intensive, costly, and difficult to operate. The damage rate is high, and the rotten seeds are as high as 28-38%.
In addition, after the seeds are shelled, they are vulnerable to diseases and insect pests, and are not suitable for use in production practices

Abstract

A rapid breeding method for sandalwood seedling relates to the plant cultivation method, in particular to a rapid breeding method for sandalwood seedling. Sandalwood seeds are immerged in the potassium permanganate solution of 0.3-0.5% to disinfect for 5-10 minutes; then the seeds are immerged in 100mg/L aqueous solution of gibberellin, then treated by ultrasound for 3-15 minutes, and continually immerged for 24 hours; the seeds are immerged in warm water at 40 DEG C for 10-15 minutes and then washed by sterile water; and the treated seeds are seeded into cultivating soil for culturing on the conditions that the temperature is 25 DEG C and the humidity is 60%. the invention has the advantages that the breeding time is shortened; the germination rate is high, the germination is started after the sowing ends for 20-30 days, and the germination rate can reach 60% in 50 days and 80% in 60 days; the sprouts grow rapidly, the seedling rate is high and can be up to more than 80% in 120-150 days from germination to growth into 25-30cm seedling; the seedling germination is tidy; the mass production and operation are convenient; and the cost is low.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a rapid breeding method for sandalwood seedlings. Background technique [0002] Sandalwood (Santalum album L.) is an evergreen tree of the family Sandalaceae, native to India, Indonesia and Malaysia, and has high medicinal and economic value. Its trunk heartwood is rich in volatile oil and is a valuable Chinese herbal medicine. It mainly has the effects of warming the stomach, relieving pain and stopping bleeding, and is widely used in the pharmaceutical industry. Sandalwood is also a valuable raw material in the production of daily chemicals. Sandalwood is an evergreen plant and is also used as a green tree species in subtropical regions. Therefore, vigorously promoting sandalwood planting has great significance for solving the shortage of sandalwood resources. [0003] Promoting the cultivation of sandalwood first needs to solve the problem of seedlings. Sandalwood is mainly pro...
