| Abstract: Aimed at solving the issues of yield decrease, poor growth vigour for greenhouse spinachcausing by unreasonable irrigation modes, the experiment focusing on the influence of micro-jet and floodingon yield, growth vigour, and chlorophyll of spinach was taken. The results showed that compared withflooding mode spinach height increased 10% and the ratio of leaf and stem increased 17.67% at the microjetirrigation mode. The micro-jet irrigation mode effectively improved the yield and chlorophyll content ofspinach for nearly 10% and 5.5%, respectively, conserved water for 30.56% and increased farmers' incomeby 20.60%. Above all, the micro-jet irrigation mode was more suitable for the growth of greenhouse spinach. |
