按照土壤肥力、气候特点,管理水平把冀北莜麦种植区分成三种生态型。根据不同生态型的特点,试拟了莜麦选育模式,以此为模板在同一时期选育出小日期高肥水品冲“冀张莜2号”。中日期中肥水品种“品六号”,大日期低水肥品种“品十四号”。形成了大中小日期、高中低肥水不同生态型系列化新品种配套,使本地区莜麦的产量比过去提高了15～30％。通过对新育品种丰产性。稳产性的分析,表明新育品种是多种优异性状的结合,是各项自身调节能力和潜在生产力的重组。也说明按照不同生态型选育莜麦新品种,是一种行之有效的方法。将在最短的时间内,最大限度地满足生产需要,取得最大的经济效益。
In accordance with soil fertility, climate characteristics, management level of northern oat cultivation is divided into three types of ecological. According to the characteristics of different ecotypes, we tried to simulate the breeding mode of oat barley and used it as a template to breed “Hebei Zhangjian No.2” in the same period. In the date of fertilizer varieties “product number six”, a large date low water and fertilizer varieties “product number fourteen.” The formation of the Dazhong Xiao date, high school low fat different series of ecological series of new varieties, so that the yield of barley in the region than in the past increased by 15 to 30%. Through the breeding of new varieties of high yield. Analysis of the stability of the new breed shows that the new breed is a combination of many excellent traits and is a reorganization of various self-regulatory capacity and potential productivity. Also shows that in accordance with different ecological breeding oat barley new varieties, is an effective method. In the shortest possible time, to maximize the production needs, and obtain the greatest economic benefits.
