- 摘要:
- 为进一步掌握近年来气候变化对东北春麦区小麦产量的影响，对4个不同类型春小麦品种连续6 a产量、千粒重、穗粒数、容重及株高性状进行分析。结果表明：近年来气候变化主要体现在小麦生育期间降水分布不均，拔节期降水量对产量形成影响较大。同时气候的变化对穗粒数影响较大，可通过提高穗粒数才获得较高产量。
- Abstract:
- The yield,1 000-grain weight,grains per spike,test weight and plant height of 4 different types spring wheat varieties were analyzed in the consecutive 6 years in order to study the effect of the climate change in recent years on spring wheat yield in northeast region.The results showed that in recent years,the climate change was mainly reflected uneven distribution of precipitation during the growth of wheat,and the precipitation in the jointing stage had great effect on the yield formation.At the same time,the change of climate had a great influence on the grains per spike.High yield could be obtained by increasing the grains per spike.
