Effects of Biogas Manure Application on Growing Development of Eggplant

[Objective] To study the effect of biogas manure application on the eggplant cultivated in open field,so as to encourage farmers to build biogas pools and use biogas.[Method] The humic pig manure and the homogeneous pig manure fermented in biogas pool over 3 months were applied to the eggplant planted in open field.[Result] The plant height,stem diameter,fruit diameter,fruit size and yield of eggplants fertilized by biogas manure were better than that fertilized by humic manure.[Conclusion] The organic fertilizer fermented in biogas tank was better than the raw organic fertilizer to the yield of agricultural crops.
