Abstract
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.
