Abstract:
Eggplant variety of ‘Hangqie 2010’ was used as experimental materials，and the water and fertilizer integration technology was used for the experiment.Four treatments were applied,conventional compound fertilizer (control)，high potassium type water soluble fertilizer and high potassium fertilizer with ameizi or fulvic acid，and the plant height，leaf area，leaf dry and fresh weight，chlorophyll content，fruit color，size，dry and fresh weight，soluble sugar and soluble solids content of eggplant were analyzed.The effects of high potassium water soluble fertilizer and different biostimulants (ameizi and fulvic acid) on the growth and fruit quality of eggplant plants were studied，in order to provide reference for the cultivation of high quality mountain eggplant.The results showed that the leaf area of eggplant was significantly increased by 112.54%，117.41% and 120.95% for both potassium fertilizer alone or with Ameizi and fulvic acid，respectively，compared with the control.Leaf dry and fresh weights were also significantly increased under each treatment compared to the control.Eggplant plant height was mostly affected by potassium fertilization with Ameizi，with an increase of 10.86%，while eggplant chlorophyll content was most affected by potassium fertilization with fulvic acid，with an increase of 28.90%.Eggplant fruit color a* values increased by 21.71%，17.57% and 2159% with potassium fertilizer alone or with amethyst and xanthic acid，respectively，compared to the control.The increase in fruit length，diameter，dry and fresh weight，and hardness treated by potassium fertilizer with Ameizi or fulvic acid were greater than that of potassium fertilizer alone.The nitrate content of eggplant fruits treated with potassium fertilizer alone or with fulvic acid was reduced by 59.74% and 53.74%，respectively，compared with the control.The application of high potassium type water soluble fertilizer alone improved the leaf area，dry and fresh weight of leaves and fruit color of eggplant，while the indicators of plant height，fruit size and soluble sugar content could be further improved by potassium fertilizer with ameizi or fulvic，indicated that the improvement effect of biostimulants on eggplant was more obvious than that of potassium fertilizer alone.
