Study on Water Absorption Characteristics and Hard Breaking Technology of Sophora moorcroftiana Seeds %A 张文莲 %A 张锦梅 %A 马光花 %J World Journal of Forestry %P 260-267 %@ 2169-2440 %D 2025 %I Hans Publishing %R 10.12677/wjf.2025.142031 %X 用西藏山南地区雅鲁藏布江流域采收的砂生槐种进行吸胀实验,筛选出硬实种子和非硬实种子,开展硬实种子硬实破除方法筛选实验。结果表明:采用吸胀法测定砂生槐种子的硬实率,测得干藏3年的砂生槐种子平均硬实率为56.41%;砂生槐因其硬实率高,播种前采取初始水温70℃浸种24 h,或种子机械摩擦后放置于湿润环境中缓慢吸水的措施,可破除硬实、节省时间、节约成本,提高同一条件成本下单位面积产苗量。
The hard seeds and non-hard seeds were screened out by the imbibition experiment of Sophora moorcroftiana collected from the Yarlung Zangbo River Basin in Shannan area of Tibet, and the screening experiment of hard seed breaking method was carried out. The results showed that the average hard seed rate of Sophora moorcroftiana seeds stored for 3 years was 56.41 %. Because of its high rate of hard fruit, it can break the hard fruit, save time, save cost and improve the seedling yield per unit area under the same condition cost by soaking the seeds in the initial water temperature of 70˚C for 24 h before sowing, or placing the seeds in a humid environment after mechanical friction to absorb water slowly. %K 砂生槐, %K 硬实休眠, %K 破除技术
