摘要
通过氰氨化钙CaCN2预处理土壤,研究了施用CaCN2对盆栽黄瓜土壤pH值、EC值及对黄瓜生长以及相关生理指标的影响。结果表明:施用CaCN2可以使土壤pH值上升,并且随着用量的增大pH值逐渐增大,但增长幅度逐渐减小;施用后对EC值的影响不大;施用10 g/盆CaCN2可以明显增加黄瓜叶绿素含量,增强根系活力,促进黄瓜生长,但施用30和60 g/盆则不同程度影响了黄瓜的生长。
The results showed that the soil pH value was increased when CaCN2 was used, but its effects on soil EC value was not very clear. The chlorophyll and root activity was increased and the cucumber seedlings were greatly enhanced after 10 g CaCN2 application in every pot. The cucumber seedlings with 30 g and 60 g CaCN2 treatment were differently decreased.
