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。
In this paper, according to the ecological characteristics in Shanghai, some key measures are put forward in ramie seed breeding technology. That sowing period to March 20 to April 20 this period more appropriate, of which the best sowing time in early April; seeding per acre of seedling to 0.75 kg is appropriate. In the pre-bed management, two-leaf period before to control the temperature-based, to prevent high-temperature seedlings; two leaf stage to four leaf stage, in order to maintain the soil suitable for water-based, to avoid lack of soil moisture, . If the ramie seed count in ensuring a certain degree of purity of the case, the Shanghai area can be their own species.
