伴生小麦对黄瓜生长及生理指标的影响

Effect of Associated Wheat on Cucumber Growth and Physiological Index

采用田间试验,研究了伴生小麦对黄瓜生长及生理指标的影响。结果表明:伴生小麦栽培模式与黄瓜单作相比,在一定程度上能够促进黄瓜生长,延缓黄瓜叶绿素和可溶性蛋白含量的下降,提高黄瓜光合作用的强度,增强黄瓜SOD、POD的活性,同时抑制黄瓜MDA含量的持续上升。伴生小麦栽培模式可以降低黄瓜叶绿素和蛋白质的降解速度,提高黄瓜抗氧化酶的活性,通过阻止氧自由基的积累,从而减缓黄瓜叶片的衰老。

Field experiment was carried out to study the effects of associated wheat on cucumber growth and physiological index. The result indicated that comparing with cucumber monoculture, associated wheat cultivation model could to certain extent accelerate cucumber growth, delay the decline of chlorophyll and soluble protein contents, improve photosynthesis intensity, enhance SOD, POD activities, and at the same time inhibite the rising of MDA content. The associated wheat cultivation model could reduce the degradation rate of chlorophyll and soluble proteins, improve the activity of antioxidant enzymes, and prevent the accumulation of oxygen free radicals, so as to slow down the senescence rate of cucumber leaf.
