摘    要:2007—2008年,多项室内外试验研究表明,旱地莜麦适期晚播时必须考虑适期范围内土壤水分、气温、地温和降水等变化趋势,确定最佳播期;干土层厚度超过5 cm,5~10 cm耕层土壤有效含水量低于8%情况下,不能保证全苗,甚至无苗;仅采用氯化钙(CaCl2)、黄腐酸(FA)、黄腐酸(FA)+水杨酸(SA)及清水浸种处理并不能有效提高出苗率。

关 键 词:晚播莜麦  土壤墒情  种子处理  出苗率

Abstract:lots indoor experiments from 2007 to 2008 indicated that, in buckwheat optimum period sowing, changing tendency of soil moisture, air temperature, soil temperature and precipitation during the optimum period must be considered to identify the optimum period. No full stand was ensured when dry soil layer is more than 5 cm and the avaiable moisture in 5 -10 cm arable layer was less than 8% and even that stand free was possible. Besiders, seed soaking treatments with CaCL2, FA, FA+SA or clean water couldn' t do anything to improve seedlings emergence rate.
Keywords:Late-sowing buckwheat  Soil moisture content  Seed treatment  Seedling emergence rate
