酸、碱、盐胁迫下4种紫花苜蓿几项生理指标变化的比较研究
Comparison of four alfalfa varieties' several physiological items change in reagents of the acid, alkali and salt
摘要
Abstract
The comparison test was set up to know the four foreign alfalfa varieties'physiology response under adversity conditions and confer their anti-intimidating traits according to their sensitivity to the adversity factors,and convenient for adjusting measures to local conditions and exerting its most productivity. Using vitriol and sodium hydroxide and lixivium from soil with different pH value reagents,the pH values were from 3 to 12,and there were ten steps altogether; when the pH value was 7 with different thickness of salt reagents, they were respectively 0. 1% ,0. 2%, 0. 3% ,0. 4%,0. 5% and 0. 6% ;once more,when the pH values were 8,9,10,11,12 respectively,with 0. 2% ,0. 3%, 0. 4% ,0. 5% and 0. 6% salt thickness accordingly. Then four alfalfa varieties were planted,their physiology items were measured and to their sensitivity was analysed. The results showed that the character of acid-resistant: Gonden Empress>Grangeur> Algonquin>Victoria; the character of alkali-resistant: Grangeur>Algonquin>Gonden Empress>Victoria;the character of salt-resistant:Grangeur>Gonden Empress>Algonquin> Victoria; the character of salt and alkali-resistant: Grangeur=Algonquin>Gonden Empress>Victoria. Therefore,four alfalfa varieties should be plant them in different soil, according to their character of the anti-intimidating.关键词
