莜麦是我国华北北部的内蒙、山西、河北坝上地区主要的粮食和饲草作物。这些地区,多属农牧过渡地带。气候寒冷,干旱多风,年降雨量300—350毫米左右。土地贫瘠,地上、地下水贫泛。绝大多数莜麦种植在旱坡地上,生产水平很低。为了明确适宜在旱、坡地生态条件下种植的优良品种应具有的形态特征,提高莜麦育种质量和栽培技术水平,我们对旱坡地莜麦产量相关的主要农艺性状的通径系数进行了初步探讨。
Barley is a major grain and forage crop in Inner Mongolia, Shanxi and Hebei Bashang in North China and North China. These areas mostly belong to the transitional areas of agriculture and animal husbandry. Cold climate, dry and windy, annual rainfall of about 300-350 mm. Barren land, the ground, groundwater impoverished. The vast majority of oats planted in dry slopes, the production level is very low. In order to clarify the morphological traits suitable for elite cultivated under the ecological conditions of dry and sloping fields and improve the breeding quality and cultivation techniques of barley, we conducted a preliminary study on the path coefficient of major agronomic traits related to the yield of barley on the sloping sloping land .
