北方冬小麦品种(系)节水抗旱性研究
Study on drought resistance and water-saving capacity of winter wheat varieties (strains) in northern China
摘要
Abstract
Through the measurement and analysis of yield,harvest index,water use efficiency,drought resistance index,canopy temperature and some agronomic traits of winter wheat varieties (strains) with different ecotypes in northern China,their drought resistance and water-saving capacity was evaluated.With the increase of irrigation amount,the yield of tested varieties was wholly increased.Since the sensitivity of different varieties to water was varied,the increase extend of yield was also different each other.Under the treatments of full irrigation,natural precipitation and drought stress,the yield of Luohan 6 was invariably the highest,being 6 316.20 kg· hm-2,2 538.75 kg· hm-2 and 1 119.75 kg · hm-2,respectively.Under the treatment of full irrigation,Zhoumai 24 was most sensitive to water,whose yield was increased by 44.12％ compared with that under natural precipitation;under the treatment of natural precipitation,Kaimai 20 was most sensitive to water,whose yield was increased by 201.47％ compared with that under drought stress.Through the correlation analysis among yield,drought resistance index and canopy temperature at filling stage,it was found that there was a negative correlation at extremely significant level between yield and canopy temperature at filling stage,and the highest correlation coefficient at middle filling stage was-0.908.Drought resistance index was negatively correlated with canopy temperature at late filling stage at extremely significant level,and the correlation coefficient was -0.453;it was negatively correlated with canopy temperature at early and middle filling stage at significant level,and the correlation coefficient was-0.342 and-0.366,respectively.关键词
