摘  要:
本文在三个施肥水平条件下比较了施用含NO3- 、SO42 - 和Cl- 离子的化肥对黄瓜生长、营养元素吸收及对土壤化学性状的影响。结果表明 :三种阴离子处理与CK相比较都表现出对黄瓜生长有一定的抑制作用 ,施肥水平越高 ,抑制作用越大。从黄瓜营养元素的吸收可以看出S、N和Cl之间存在竞争性抑制 ,且在叶含量中表现更明显。三种阴离子处理都使黄瓜根、茎、叶中Mn的含量增加 ,可能是由于三种阴离子处理均使土壤EC值上升、pH下降 ,增加了Mn的可溶性 ,植物易于吸收所致。

摘  要:
The effects of fertilizers with different anions(NO 3 -?SO 4 2- andCl -)were tested on the growth and mineral absorption of cucumber. The results showed that all the three kinds of anions had inhibition effect to the growth of cucumber to some degree,the higher the fertilizer level was the stronger the inhibition effect as compared with CK.The results of the three kinds of anions on mineral elemnts absorption indicated that that there was some kind of competitive inhibition relationship among S,N and C1.All of the three kinds of anions treatments could increase the content of Mn in roots,stems and leaves of cucumber.All treatments by the three kinds of anions could make the EC value increase and the PH value decrease and then resulted in the increase of absorption of Mn and made Mn element easily absorbed.
