| Abstract: In order to study the effect of complex enzyme glycoside (CEG) on rooting and yield of cucumber, cucumber 'Haiyang' was used as experimental material, and five concentration gradients (1, 5, 10, 20, 50 mg/kg) of CEG were set to study their effect on rooting and yield of cucumber. At the same time, the effects of different plant regulators (CEG, diethyl aminoethyl hexanoate, butyl butyrate and synergistic amine) on root growth, fresh weight, plant height and yield of cucumber were also studied. The results showed that when the concentration of CEG was 5 mg/kg, the root system of cucumber was significantly promoted, the total root length, root surface area, root average diameter, root branch number and root tip number of cucumber were significantly larger than that of the control, and the promotion effect became more obvious with the increase of CEG concentration. Compared with other plant regulators and control, the CEG could significantly increase root activity, fresh foot weight, plant height and yield per 667 m2 of cucumber, and promote the growth of total root length and root surface area. It was concluded that 10 mg/kg CEG was suitable for flushing after sowing of cucumber. |
