2种莜麦在河南的生长特点与生产水平的分析

Analysis on growth characters and production levels of two species of naked oat (Avena nuda) in Henan Province

把来自内蒙古的2个莜麦Avena nuda优良品种内农大莜1号和内农大莜2号,引种到河南省黄河滩区来种植,研究其生长特点以及生产水平,目的是通过与原产地生产水平的比较,来探索这2个莜麦品种在河南推广的可能性和必要性。结果表明:莜麦能很好地适应河南省黄河滩区土壤和气候条件,表现出生长速度快和生产水平高的特点,内农大莜1号和内农大莜2号的饲草干物质产量分别为1608.1和1472.8g/m2,果实产量分别为457.6和481.7g/m2,均显著地高于原产地的生产水平。

To found a possibility and necessity of introduce naked oat （Arena nuda） into Hennan Province, growth characters and production levels of 2 species, Neinongda Oats-1 and Neinongda Oats-2, from Inner Mongolia were studied at yellow river beach in Henan Province. Grain yields were 457.6 g/m^2 and 481.7 g/m^2, and forage yields （DM） Were 1 608. 1 g/m^2 and 1 472.8 g/m^2. These were higher than thai in Inner Mongolia. This imply that the two species are adapted to the soil and the climate of the area.
