Study on Screening of Eggplant Cultivation Substrate Formula in Solar Greenhouse Based on Agricultural Waste
Through the composting of corn stover and cow dung in the Hexi region,the optimal cultivation substrate formulations suitable for local sunlight greenhouse eggplant cultivation were screened to provide a scientific basis for the recycling of agricultural wastes.The growth and yield benefits of eggplant cultivated under different formulations of substrates were studied in pot planting experiments with Changqie 1 as an indicator variety.The results showed that with the formulation of rotted corn stover:river sand:vermiculite:rotted cow dung:aconite powder:perlite compounded into the cultivation substrate according to the volume ratio of 6∶1∶1∶1∶0.5∶0.5,the eggplant yield was the highest and benefit was ideal,which were 1.29 kg/plant,1.39 Yuan/plant,respectively,and the eggplant plant height,stem thickness,chlorophyll content,biomass,and number of fruits per single plant were all the best.This formula is suitable for the application and promotion of eggplant substrate cultivation in solar greenhouse in the Hexi region.
