中文摘要	采用盆栽方法,研究了镍毒害条件下外源钙对大豆镍毒害的缓解效应以及对其叶片组织中超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、过氧化物酶(POD)和抗坏血酸过氧化物酶(APX)活性的影响,以探讨钙缓解植物镍毒性的生理机制。研究结果表明:Ni~(2+)60 mg/kg添加量对大豆幼苗生长表现出明显的抑制作用,但是当加入不同钙量后,大豆的镍毒害症状得到不同程度的缓解,Ca~(2+)200 mg/kg处理的缓解作用好于Ca~(2+)100 mg/kg。与不施镍处理相比,单施Ni~(2+)60 mg/kg处理的大豆叶片组织SOD、CAT和APX活性明显下降,而POD活性明显上升。当配施Ca~(2+)以后,大豆叶片组织中SOD、CAT、POD和APX活性明显提高,且Ca~(2+)200 mg/kg处理的上升程度比Ca~(2+)100 mg/kg处理的大。因此,Ca~(2+)是通过提高叶片组织抗氧化酶活性,增强活性氧清除能力,而使大豆的镍中毒症状得到缓解,这是Ca~(2+)减轻大豆镍毒害的生理机制之一。
英文摘要	The main objective of this study was to reveal the growth and yield of waxy corn in different nitrogen fertilizer and density in seasonal arid region. Field experiments were conducted at jinxian country,Jiangxi province. Yield and yield components were determined and air temperature and rainfall were monitored. The results showed that drought was occurred in September,October and November in 2011. Fresh fruit spike production was increased gradually with increasing amount of density and nitrogen. Fresh fruit in 225 kg /hm~2 nitrogen fertilizer and 60 000 plants /ha was highest in all treatments. It was increased by 32. 29% than none nitrogen treatment. Nitrogen agriculture efficiency of 175 kg /hm~2 nitrogen with 52 500 plants /ha and 175 kg /ha nitrogen with 60 000 plants /ha were 10. 57 kg /kg and 11. 79 kg /kg,respectively. They were higher significantly than others. Nitrogen agriculture efficiency of 275 kg /hm~2 nitrogen with 4 500 plants /ha was 3. 76 kg / kg,and it was the lowest.
