Embodiment 1

[0017] A method for breaking pine grass seed dormancy, characterized in that the method comprises the following steps:

[0018] (1) Seed collection: select robust plants without damage by diseases and insect pests, cut off the whole inflorescence with scissors and dry it in the sun when the seeds are fully mature, and screen out plump and fully mature seeds for subsequent use;

[0019] (2) Soak the pine grass seeds with a temperature concentration of 30g / L potassium dihydrogen phosphate solution for 13 hours, then soak them in thiophanate-methyl 600 times solution for 2 hours, and finally wash the seeds with warm water at about 30°C;

[0020] (3) Preparation of plant extract: select well-developed plants, collect roots, stems, and leaves of vetiver, cut them into pieces with scissors after drying in the shade, weigh 2, 10, and 4 g of roots, stems, and leaves respectively, and add 100 times Distilled water, soaked at 25°C for 48 hours, filtered through 4 layers of gauze to obta...

Abstract

The present invention discloses a method for breaking thalictrum aquilegifolium seed dormancy. The method mainly comprises seed selecting, seed soaking treatment, soaking with a plant leaching solution, and stacked volume treatment. According to the present invention, the soaking, the stacked volume treatment and other technologies for breaking seed dormancy are comprehensively utilized so as to substantially shorten the thalictrum aquilegifolium seed germination time, and the thalictrum aquilegifolium seed obtained in the present invention has the following characteristics that: the tree seedling root system is developed, the growth is good, the speed is fast, and the survival rate.

Description

technical field [0001] The invention relates to a method for breaking the dormancy of pine grass seeds. Background technique [0002] Tang pine grass, Ranunculaceae, Tang pine grass genus, perennial herb, glabrous, up to 70 cm, with branches. The leaves are 2-3 times and 3 compound leaves; the leaflets are obovate to nearly round, 1-2.5 cm long, 0.8-3 cm wide, not obvious 3-lobed, the top of the lobes has notched cognate teeth, the base is cuneate, round to nearly round Heart-shaped. Monokyme cymes; flowers about 1 cm in diameter; sepals greenish-white, obovate; stamen filaments swollen into rods; carpels usually 3-6, glabrous, flowers curled. The flowering period is April, and the fruiting period is July-August. Produced in Nanjing, Jurong, Yixing, Suzhou, Shanghai and other places, growing in damp places under hillsides or ravine forests; distributed in northern Jiangxi, southern Anhui, and eastern Zhejiang. The root is used as medicine, which has the effects of detoxi...
