【 摘 要 】

Weeds are difficult to control in processing cucumber (Cucumis sativus)production because of the growth habit of cucumber and its sensitivity to herbicides. Onealternative method is utilizing short-cycle summer cover crops, such as commonbuckwheat (Fagopyrum esculentum) prior to planting cucumber. However, this needs tobe tested to assess any potentially negative influences of buckwheat on cucumber yields.To examine the effects of buckwheat on cucumber growth, four field experiments wereconducted in 2008 and 2009 in northern and central Illinois and two greenhouseexperiments were conducted in Urbana, IL in 2010.Using buckwheat as a cover crop prior to direct-seeding cucumber had negativeeffects on overall cucumber growth and yield in both field and greenhouse experiments. .In the field experiments, buckwheat reduced weed growth during the buckwheat stand,but did not provide long-term weed suppression during the cucumber growth period, andcaused inhibition of cucumber growth and reduction of cucumber yield, making itunsuitable to be used as cover crop prior to cucumber if there is only a seven-day periodbetween incorporation and seeding processing cucumbers. In the greenhouseexperiments, cucumber plants grown in soil that had previously grown buckwheat sevendays earlier were smaller and less vigorous than those grown in soil with no buckwheatresidues or containing only buckwheat shoots. Direct-seeding cucumber into buckwheatresidues only one week after killing the buckwheat is not advisable as cucumber growthand yield will be reduced as a result.
