Abstract:
Taking ‘Lyufeng No.1’ eggplant as the test material,four treatments were set up with a reduction of 15%,25%,35%,and 45% of chemical fertilizer as a substitute for biological bacterial fertilizer.The conventional chemical fertilizer (nitrogen phosphorus potassium compound fertilizer,N∶P∶K=5∶20∶20) applied throughout the year at a rate of 2 250 kg·hm-2 was used as a control to study the effects of chemical fertilizer reduction combined with biological bacterial fertilizer on the growth,yield,fruit quality,and photosynthesis of facility overwintering eggplants,in order to provide reference for future planting and production.The results showed that reducing chemical fertilizer by 35% and replacing it with an equal amount of biological bacterial fertilizer,applying a ternary compound fertilizer of 1 462.5 kg·hm-2+biological bacterial fertilizer of 787.5 kg·hm-2,could effectively enhance the photosynthesis of plants during flowering and fruiting periods,increase the growth and yield of overwintering eggplants,and achieve the optimal input-output ratio.
