摘要:
为了解4种进口紫花苜蓿在逆境条件下幼苗生理响应特点,并比较其对逆境因子的敏感程度以推测其抗逆性,便于指导在我国的因地制宜种植,发挥最大生产性能,特进行比较试验研究。用H2SO4、NaOH、土壤浸出液分别配制pH为3、4、5、6、7、8、9、10、11、12的试剂;当pH为7时,用土壤浸出液配制NaCl浓度分别为0.1%、0.2%、0.3%、0.4%、0.5%、0.6%的试剂;再配制pH分别为8、9、10、11、12,NaCl浓度分别相应为0.2%、0.3%、0.4%、0.5%、0.6%的试剂。分别种植4种苜蓿,检测生理指标,分析敏感性。结果:耐酸能力表现为:金皇后>飞马>阿尔冈金>维多利亚;耐碱能力表现为:飞马>阿尔冈金>金皇后>维多利亚;耐盐能力表现为:飞马>金皇后>阿尔冈金>维多利亚;耐盐碱能力表现为:飞马=阿尔冈金>金皇后>维多利亚。结论:根据4种紫花苜蓿的抗逆特点,分别选择合适的土壤种植。
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.
