不同浓度铬对黄瓜氮磷钾吸收分配的影响

Effect of different concentrations chromium to cucumber N,P,K absorption distribution

采用神鲁青瓜王子杂交一号黄瓜为试验材料,在光照培养箱中培养,利用霍格兰营养液施肥。用流动分析仪、钼锑抗比色法、火焰光度法测定氮、磷、钾的含量。研究不同浓度铬胁迫下黄瓜幼苗根、茎、叶对营养元素的吸收,可为黄瓜养分吸收与利用提供理论依据。

Using Prince Shen Lu Cucumber Hybrid 1 cucumber seeds as the test material,in the light of the culture box,using hoagland nutrient solution cultivate hydroponic cucumber. The flow analyzer,Molybdenum antimony colorimetric method and flame photometry to determined the content of nitrogen,phosphorus and potassium. To study the effects of different concentrations chromium force on cucumber seedling roots,stems,leaves absorption nutrients,which can provides new theoretical support for this kind of research about cucumber nutrient absorb and use.
