10个山东省小麦品种节水丰产性鉴定与分析
|
摘要
为了筛选出节水丰产性小麦品种,以灌溉次数为主处理,以10个主要推广品种为副处理,研究各品种在不同灌溉次数下产量、产量构成因素、水分利用效率的表现。结果表明:随着灌溉次数的增加,10个品种的产量、单位面积穗数均呈现上升趋势,水分利用效率呈现下降趋势,而穗粒数和千粒重没有一致性的规律。相关性分析表明,产量与单位面积穗数呈极显著正相关,而与穗粒数和千粒重呈正相关但不显著。通过综合评价,筛选出抗旱、节水、丰产性好的品种鲁原502、山农22和泰农18,这为节水丰产性小麦品种的选用推广提供了依据。
In order to screen the water-saving and high-yield wheat varieties,taking irrigation frequency as the major treatment and 10 wheat varieties as the minor treatment,the yield,yield components and water use efficiency of 10 wheat varieties under different irrigation frequencies were studied. The results showed that both the yield and the number of spikes per hectare increased with the increase of irrigation frequency,while the water use efficiency decreased. There was no coincident regularity between grain number per spike and thousand kernel weight. Correlation analysis showed that the yield was highly significantly correlated with the number of spikes per hectare,while had positive but not significant correlations with the grain number per spike and thousand kernel weight. According to comprehensive evaluation,Luyuan 502,Shannong 22 and Tainong 18 were screened out as better varieties with water-saving and high-yield characteristics,and this study provided references for selecting and popularizing of water-saving and high-yield wheat variety.
