| 摘 要： | 试验采用 3种含不同阴离子的化肥 ,设 3个施肥水平 ,研究了它们对黄瓜生长、根系活力及对土壤EC、pH的影响。研究结果表明 :在 3个施肥水平下 ,化肥的不同阴离子对黄瓜生长的抑制作用是Cl->SO42 ->NO3 -,土壤中浓度越大 ,抑制作用越明显。土壤中随 3种离子浓度增高 ,EC值明显增大 ,pH值明显下降 ,其影响是Cl->SO42 ->NO3 -。 |

Effects of fertilizers with different anions on the growth of cucumber and EC and pH of soil |
|
| Abstract: | The effects of three kinds of fertilizers with different anions, and three levels of fertilization amounts on the growth and succinic dehydrogenase activity of cucumber and EC and pH of soil were tested The results showed that at three levels of fertilization, the effect of fertilizers with different anions on the growth of cucumber is Cl ->SO 4 2- >NO 3 -,the higher anion amount in soil is, the clearer its restrain is The EC of soil solution increases and pH decreases clearly with increase of anion amount in soil, the effect of anions on soil is Cl ->SO 4 2- >NO 3 - |
| Keywords: | Anions fertilizer cucumber soil |
