[0003] Dalbergia Dalbergia blooms from March to April, and a large number of pods mature in October of that year. The spring sowing time of seeds is February to March, so Dalbergia seeds need to be stored for 4-5 months before sowing. After 4-5 months of sand storage by conventional methods, The germination rate of the seeds is significan...

Embodiment 1

[0022] A method for treating seeds of Dalbergia sowing seedlings, comprising the following steps:

[0023] S1. Seed collection: in October, when the peel changes from yellow-green to yellow-brown, pick the pods; fully dry the pods, rub them, and remove the pods.

[0024] S2. Seed cleaning: remove empty seeds, diseased seeds, damaged seeds and inclusions.

[0025] S3. Plant extract treatment: soak the seeds in 5g / L ginger extract for 12 hours; the ginger extract is extracted using microwave-assisted extraction, distilled water is used as a polar solvent, and the ratio of solid to liquid is 1:6. The power is 550W, and the microwave treatment time is 60s. After the extraction is completed, add water to dilute to a concentration of 5g / L.

[0026] S4. Hormone treatment: first prepare a hormone treatment solution, which includes 0.4g / L auxin and 0.6g / L gibberellin, the auxin is indole acetic acid, and the seeds are placed in hormone treatment Soak in the liquid for 24 hours; durin...

Abstract

The invention relates to a seed treatment method for sowing and seedling raising of Dalbergia hupeana Hance. The method mainly includes the steps of seed collecting, seed purifying, plant extract treatment, hormone treatment, ultra-drying treatment, storage, ultrasonic treatment and rewetting treatment. In the step of hormone treatment, seeds are soaked with gibberellin and auxin mixed liquor for 24 h; in the step of ultra-drying treatment, a silica gel drying method is adopted, the weight ratio of silica gel to the seeds is 5:1, used silica gel is replaced with fully-cooled dry silica gel every day, and the Dalbergia hupeana Hance seeds with the water content of 3.9-4% are obtained by controlling treatment time; in the step of storage, the seeds are sealed in a double-layer aluminum foil bag to be stored at the room temperature; in the step of ultrasonic treatment, the seeds at different grades are treated under different ultrasonic conditions; in the step of rewetting treatment, a step-by-step resetting method is adopted. By means of the method, the Dalbergia hupeana Hance seeds can show high vitality and resistance after being stored for a long term; compared with a conventional seed treatment method, the germination rate, germination potential, germination index and vitality index of the Dalbergia hupeana Hance seeds can be significantly increased.

Description

technical field [0001] The invention relates to the field of Dalbergia seedlings, in particular to a method for treating Dalbergia seedlings. Background technique [0002] Dalbergia (scientific name: Dalbergia hupeana Hance), alias: I don't know spring, Wangshui sandalwood, sandalwood, sandalwood, white sandalwood; Papilionaceae, Dalbergia hupeana arbor plant, is a high-quality tree species for garden applications; the wood structure is fine and dense , It is a material for making appliances and equipment with high-quality load-bearing and strong pulling force. The root bark can be used medicinally, and has the effects of clearing heat and detoxifying, stopping bleeding and reducing swelling. Widely distributed throughout China. [0003] Dalbergia Dalbergia blooms from March to April, and a large number of pods mature in October of that year. The spring sowing time of seeds is February to March, so Dalbergia seeds need to be stored for 4-5 months before sowing. After 4-5 m...
