文章摘要：以連作營養(yǎng)基質（10茬）添加質量比為3%和5%生物炭為處理,以不添加生物炭為對照,采用日光溫室黃瓜桶栽試驗,研究連作營養(yǎng)基質添加生物炭對其理化性質及黃瓜生長的影響。結果表明,添加生物炭的處理,顯著提高營養(yǎng)基質pH、有機質和速效鉀含量,促進黃瓜葉片光合作用,提高產量,降低果實硝酸鹽含量,其中以添加5%生物炭處理效果最為明顯。相關分析表明,黃瓜產量與速效鉀含量和pH呈正相關,與有機質呈極顯著正相關（P〈0.01）。本研究為利用添加生物炭改良連作營養(yǎng)基質提供理論依據(jù)。

Abstr：A pot experiment was conducted to study the effects of biochar on physicochemical properties of nutrition medium and cucumber growth under continuous cropping in a greenhouse. The results showed that pH, organic matter and available K content of nutrition medium are improved by biochar treatments significantly, as well as the photosynthesis of cucumber leaf and cucumberyield are increased, but the nitrate content in fruit is reduced. Moreover, the effects result from application of 5% biochar are more obvious than that of 3% biochar. Correlation analysis showed that there is positive correlationship between the cucumber yield and available K concent and pH at the level of P 〈 0.05, and significantly positive correlationship between cucumber yield and organic matter at P 〈 0.01. It was suggested that biochar could be used as the effective measures to improve nutrition medium under vegetable continuous cropping.
