| 摘 要： | 在锌污染蔬菜基地进行有机肥、钙镁磷肥、石灰等农化措施修复土壤生产能力的田间小区试验研究,结果表明:3种农化措施处理锌污染土壤后,能明显提高土壤上种植的冬春季、秋冬季蔬菜作物的产量,适当的农化措施联合处理可达到当地常规产量水平,与对照相比,生姜季增产15 38%～23 08%,莴苣季增产35 9%～82 5%;农化措施对夏秋高温季节种植的花生等对锌极敏感作物有延缓死亡、提高存活率的作用,但还不能达到作物正常生长、收获产量的目标。农化措施处理锌污染土壤,明显降低作物中锌含量,锌含量与作物产量呈反相关趋势。研究中发现,钙镁磷肥、石灰处理土壤后明显降低土壤有效锌含量,但有机肥施用后并不降低土壤有效锌含量,而作物锌含量却明显降低。

| Abstract: | The observations from the field plot-experiments conducted on the vegetable base of Shengzhou county of Zhejiang province to explore the effects of organic manure, fused calcium magnesium phosphate and lime on the remediation of productivity in zinc-contaminated soil showed that: all the three kinds of agro-chemical measures evidently increased yields of vegetables grown in winter-spring and autumn-winter seasons on zinc-contaminated soils. Normal local yield level of ginger and lettuce could be gained by using the optimum combination of agro-chemical measures. Yields of ginger and lettuce increased 15.38% to 23.08% and 35.9% to 82.5% as compared with CK, respectively. These agro-chemical measures could leave death and increase the livability of peanut plant (highly susceptive to zinc poison) grown in summer-autumn high-temperature seasons, although it can't get the normal growth and expected yielding levels of peanut. Zinc content in plant could be decreased evidently by using agro-chemical measures and there is a opposite relationship between the yield and zinc content of the plants. Also, we found that the available zinc content in the polluted soils could be decreased by using the treatments of fused calcium magnesium phosphate and lime in polluted soils; however, to apply organic manure may be valid to the decrease in the zinc content of plant rather than in the zinc contents of polluted soils. |
