The invention discloses a method for promoting seed germination of straw fruits, which comprises the following steps: collecting fresh and ripe straw fruits without pests and diseases, stacking straw fruits at room temperature in breathable plastic woven bags for 2 to 3 days, peeling the outer pericarp, and obtaining seed masses; stacking seed masses in clean containers for 12 to 18 hours, and then rubbing and washing the seed masses in clean water to remove the pulp and fruit mass. The seeds were soaked in sterile water for 2 to 4 days at 5 C and in dark conditions. The treated seeds were disinfected and placed in indoor ventilation, dried and dried, and the straw seeds were stratified. The method provided by the invention for promoting the germination of grass and fruit seeds has a germination rate of more than 80%, effectively promotes the germination rate of grass and fruit seeds, has important significance for the cultivation and popularization of grass and fruit, is easy to be operated manually, and has high practical application value for seedling raising and large-scale planting of grass and fruit seeds.

一种促进草果种子萌发的方法
本专利技术涉及植物栽培
,具体为一种促进草果种子萌发的方法。
技术介绍
草果(AmomumtsaokoCrevostetLemarie)隶属于姜科(Zingiberaceae)豆蔻属(Amomum),产于云南、广西、贵州等省区。以干燥成熟果实入药,具有燥湿温中,截疟除痰之效,用于寒湿内阻,脘腹胀痛,痞满呕吐,疟疾寒热和瘟疫发热。此外,草果还可作调味香料,全株可提取芳香油。在生产上,草果以种子繁殖为主,但草果种子采收后不能干燥贮藏,晒干后容易失去活力,且刚采收的草果种子处于休眠状态,直接播种发芽缓慢,萌发率低,出苗不整齐。现有研究表明,GA3、H2SO4、NaOH或湿沙藏等处理均能促进草果种子的萌发,但效果不佳,最高萌发率仅50%左右。
