Abstract:
Biochar plays an important role in soil improvement and crop production，it is an important strategy to realize the sustainable development of facilities vegetables to explore the influence of biochar on physical and chemical properties of soil and yield of vegetable crop.This study explored the influence of the biochar on soil pH，capillary water holding capacity，growth characteristics at different development stages，root characteristics and yield of the eggplant by adding different proportions of biochar in soil （1 kg?m-2，2 kg?m-2，3 kg?m-2，4 kg?m-2).The results showed that，soil pH，soil capillary water holding capacity and content of soil organic matter increased gradually with the increase of biochar content，the average soil pH，soil capillary moisture capacity，soil organic matter content was 1.27，1.15，1.58 times of control′s，respectively;applying biochar in soil could effectively promote the root growth and yield of eggplant，the eggplant taproot length，root diameter，total root fresh mass and root surface area of C3 treatment were 1.15,1.32，1.28 times and 1.38 times of control′s，respectively.Plant height and stem diameter increased by 32% and 44% than control，respectively，yield increased by 37%.Plant height and stem diameter than the contrast increased 1.32 times and 1.44 times respectively，the yield increased 1.37 times.The phase relationship analysis results showed that the eggplant yield had the highest correlation with the total root surface area and the correlation coefficient was 0.979.Biochar could optimize soil physical and chemical properties and had a certain role in promoting root morphological characteristics and production of the eggplant.This research laid a good foundation for the application of biochar to increase greenhouse eggplant production.
