通过盆栽试验比较了20种作物的耐氯力.结果表明,临界浓度大于600μgg~(-1)者为强耐氯作物,300～600μgg~(-1)为中等耐氯作物,小于300μgg~(-1)为弱耐氯作物.在土壤含氯本底值7～50μgg(-1)的条件下,施入的氯离子浓度小于200μgg~(-1),时,对作物生长、产量和品质一般无不良影响.而对一些作物还有增产作用.200～400μgg~(-1)时,对中、强耐氯作物无影响,对弱耐氯作物略显不利.400～800μgg~(-1)时,对强耐氯作物有较小影响,对中、弱耐氯作物影响较大.大于800μgg~(-1),对多数作物产生毒害作用.
Chlorine tolerance of 20 crops was compared by pot experiment.The results showed that the chlororescents with high critical concentration of more than 600 μg / (-1) were highly resistant to chlorine, 300-600 μg (-1) moderately resistant to chlorine and less than 300 μg ~ (-1) -1) were weaker and less resistant to chlorine.Under the condition of 7 ~ 50 μg / (-1) of soil background, the concentration of chloride ion was less than 200 μg / (-1), the effect on crop growth, yield and quality Generally no adverse effects, while some crops have increased production .200 ~ 400μgg ~ (-1), the medium and strong resistance to chlorine no impact on the weak resistance to chlorine crops slightly negative .400 ~ 800μgg ~ (-1 ) Had less impact on strong chlorine tolerant crops and had a greater impact on medium and weak resistance to chlorine crops and greater than 800 μg / (-1) toxic effects on most crops.
