摘要
为确定日光温室秋冬茬黄瓜生产的合理施钾量,以宁夏银川郊县二代日光温室秋冬茬黄瓜为材料,进行了不同钾肥施用量对其产量的影响研究。结果表明：在低钾水平下（0~51.4 kg/667m2）,增产作用较明显,超过最高产量施钾量（51.4 kg/667m2）时,继续加大施钾量,其产量呈下降趋势。
Effect of application amount of potassium fertilizer on cucumber yield was studied taking autumn-winter cucumbers in the second generation heliogreenhouse in Yinchuan suburban county of Ningxia Hui Autonomous Region to confirm the rational application amount of potassium fertilizer for autumn-winter cucumber production in heliogreenhouse.The results showed that the yield of cucumber significantly increased with the increase of potassium fertilizer and reached the highest when the application amount of potassium fertilizer was up to 51.4kg/667m2,but the increase rate decreased when the application amount of potassium fertilizer was more than 51.4kg/667m2.
