为了探索棉花水、旱生态型存在的可能性,发掘棉花耐旱新类型,我们进行了棉花品种对水旱生态条件反应的研究。一、材料和方法本研究于1988年在山西省农业科学院棉花所(运城)进行。所址地处黄土高原半干旱地区。生态条件分重病水地、轻病旱地和抗旱大棚3种。试验内容分2组:第1组是丰产对照品种对水、旱生态条件反应的比较,引用了耐旱育种水,旱育种程序中5个高级计产试验的产量结果。援引的每个试验均以丰产推广品种中为对照。统计分析项目有霜前花％,霜前皮
In order to explore the possibility of existence of cotton water and drought ecotype, and explore the new types of drought-tolerant cotton, we studied the cotton varieties’ ecological response to drought and drought. I. Materials and Methods This study was conducted in 1988 at the Cotton Institute of Shanxi Academy of Agricultural Sciences (Yuncheng). The site is located in semi-arid area of Loess Plateau. Ecological conditions of severely ill water, light dry land and drought-tolerant greenhouse 3 kinds. The experiment was divided into two groups. The first group was the comparison of the responses of high yielding varieties to water and drought ecology, and the yield results of five high-level yield test in drought and drought breeding programs were cited. Each of the tests quoted was based on a high yielding variety. Statistical analysis of the project before the flower frost% cream front skin
