【摘要】 为了探明不同盐碱浓度对燕麦生育性状的影响,本试验研究了大田盐碱胁迫对4个燕麦品种的产量和籽粒品质的影响。结果表明：盐碱胁迫对不同燕麦品种的产量和籽粒品质都有明显的抑制效应,并随着盐碱程度的增加,产量呈递减的趋势；不同燕麦品种对土壤盐碱胁迫的反应不同,其耐盐碱的强弱顺序依次为：白燕1号＞草莜1号＞坝莜1号＞白燕7号；在盐碱地上产量受限制的直接因素是千粒重和穗粒数,另外干旱也是影响燕麦产量形成的主要环境生态因子。更多还原

【Abstract】 In order to verify the effect on oats birth character under different saline-alkali density,the ex- periment were studied the effect of saline-alkali stress on yield and grain quality of 4 oats varieties under three different soil salt concentration.The result showed that the effect of yield and the grain quality of different vari- eties all has the obvious inhibitory action under saline-alkali stress,and along with the salt alkaloid degree in- crease,the yield of oats assumes the degressive tendency;the different variety showed the different reactions. The varieties effected were sorted in an order of Baiyan 1＞Caoyou1＞Bayou 1＞Baiyan 7;The yield was direct- ly restricted by kernels per ear and 1000 grain weight,moreover the drought also is the main environment eco- logical factor which the oats output forms.更多还原
