上海地区苎麻种子育苗技术研究

本文针对上海地区的生态特点,在苎麻种子育苗技术中,提出了一些关键性的措施。即播种期以3月20日至4月20日这一时期比较合适,其中以4月初为最佳播种时间;播种量每亩秧田以0.75公斤左右为宜。在苗床前期管理中,二叶期以前,以控制温度为主,防止高温烧苗;二叶期至四叶期,以保持土壤适宜水分为主,避免因土壤水分不足,导致麻苗失水死亡。如果在保证苎麻种子县有一定纯度的情况下,上海地区可以自行留种。

The Technical Research for Seedling from seed of Ramie in Shanghai Area

According to the ecological characteristics of Shanghsi area,a few key measures for growing seedlings of Ramie are provided in this paper.The suitable seedling time is between the last ten days of March and second ten days of April. The suitable seedling rate is about 0.75 kg per mUo In early stage management of seedting bad,the temperature control should be considered as a main measure to prevent the seedling from the injury of high temperature.Between two leaves stage and four leaves stage,the bad should be kept at appropriate moisture to avoid the shortage of moisture in soil,which may course seedling dying of water losing.If the fairy pure degree of seeds is sustained,the area may have the seed stoch for itself.
