设施条件下不同轮套作对黄瓜产量及品质的影响

Effects of Different Rotations and Interplantings on Cucumber Yields and Qualities under Protected Cultivation

研究了不同轮套作栽培方式对黄瓜产量及品质影响。结果表明:小麦及大豆轮作处理的产量极显著高于其它处理(P<0.01),其它处理显著高于对照(P<0.05)。轮套作处理的可溶性固形物及维生素C含量均高于对照;硝酸盐含量以小麦、大豆、显著低于对照(P<0.05),其它处理与对照差异不显著;亚硝酸盐含量除毛苕子外其它处理显著低于对照,表明轮套作对黄瓜营养品质的改善有一定作用。设施栽培条件下,合理的轮套作有利于作物增产和品质的提高。对于黄瓜栽培中,小麦及大豆轮作处理最有利于提高黄瓜产量及品质。

This experiment investigated effects of different ways of rotations and interplantings on cucumber yields and qualities. The results showed that yields of wheat treatment and soybean treatment in rotation system were extremely significantly higher than other treatments （P〈0.01）, and other treatments were significantly higher than contrast （P〈 0. 05）. Contents of soluble matters and vitamin C of rotation and interplanting treatments were higher than contrast. Contents of nitrate of wheat and soybean treatments were significantly lower than contrast （P〈0.05）, but there were not significant differences between other treatments and contrast. Contents of nitrite of different treatments were significantly lower than contrast except Vicut vllosa L treatment. All of these indicated that rotation and interplanting had some effects on the improvement of cucumber＇s nutrition and qualities. Reasonable rotation and interplanting could increase crops＇ yields and improve their qualities under protected cultivation. Rotation of wheat or soybean treatments had more effects on the raise of cucumber yields and qualities.
