旱地大豆品种资源依其来源不同划分为3种类型:一、晋西黄土丘陵区旱地品种(以下简称西山旱地品种);二、晋东土石山丘陵区旱地品种(以下简称东山旱地品种);三、平川旱地品1种(包括我所及省内外科研单位育成的旱地品种)。为探讨不同类型旱地品种资源的生态型特点,选取西山基点品种资源试验的50份旱地品种材料分别代表上述3种品种类型,对其农艺生态性状进行对比分析。抗旱性 1982年于结荚、鼓粒期遇到严重干旱时观察上述3类旱地大豆品种的抗旱性。该年严重干旱,0—30公分土层土壤含水量为10.3％。不同类型旱地大豆品种在西山种植表现出不同
The dryland soybean resources are divided into three types according to their sources: a. Dryland cultivated land in western Shanxi Loess Hilly Region (hereinafter referred to as dry land cultivated in the Xishan Mountains); Second, dryland cultivated in a mountainous area in the mountainous area of Eastern Shanxi (hereinafter referred to as Dongshan dry land cultivars); , 1 species of Hirakawa dryland products (including dryland varieties bred by research institutes both inside and outside our province and outside). In order to explore the ecological characteristics of different types of dryland resources, fifty dryland cultivars selected from the Xishuanganyuan variety resources were used to represent the above three types of cultivars, respectively, and their agronomic traits were compared. Drought resistance In 1982, during the podding and drumming stages, drought resistance was observed in three types of dryland soybean cultivars. Severe drought that year, 0-30 cm soil moisture content of 10.3%. Different types of dry land soybean varieties show different planting in Xishan
