摘要
近年来,我国诸多省市区的农业环境不断恶化,农产品的重金属污染事件经常见诸报刊,重金属污染现象应该引起我们足够的重视。故了解清楚某些常见的重金属对土壤、农作物生长的影响有重要现实意义。本文通过对胡萝卜在添加了锌溶液的土壤中的生长情况实验分析,分析了土壤中不同浓度的锌对胡萝卜生长的影响特点;在不同的锌浓度梯度下,胡萝卜生物量明显不同。结果表明,在试供的浓度范围之内,土壤中锌的浓度越高,胡萝卜生物量越大。
Currently, the deterioration of the environment and agricultural regional agricultural contamination by heavy metals is also very serious. Survey of heavy metals impact in the soil and crops has great practical significance. Based on the bitter zinc concentration in the growth of different tests, illustrates the impact of characteristics of different zinc concentrations in soil on plant growth; Zinc and at different concentration gradients, the size of biomass significantly different, Tests showed that in the concentration range of the test for, the higher the concentration of zinc in the soil, the greater the bitter biomass.
