This data comes from a two-stage plant-soil feedback greenhouse control experiment, including soil regulation stage, feedback stage and soil microbial diversity inoculation experiment. The experiment used 4 species of gramineae and 4 species of leguminous plants, setting 1, 2, 4 and 8 species richness and different gramineae: leguminous compositions. The conditioned soil was collected from the corn field of Nanjing Baima Experimental Base (31°37′N, 119°11′E). After removing roots, it was mixed with sterilized sand 1:1. Each pot was filled with 0.5 kg of dry soil. The plants were cultured for 4 months. In the feedback stage, 20 plant combinations and 20 regulated soils were cross-configured, with 4 replicates per combination, totaling 1600 pots; after 4 months of cultivation, the aboveground and underground parts were separated, dried at 65 ℃ for 48 hours, and then weighed.

The experiment adopted unified greenhouse conditions, with a light-dark period of 16/8 h, a day and night temperature of 20/15 ℃, and a soil water content of about 65%. During the feedback phase, 4 replicates were set for each plant-soil combination. After harvest, the plants were dried at 65 ℃ for 48 hours and the dry weight was weighed. After data entry, check the original records, processing numbers, measurement units and missing values, and check the consistency of the total biomass and the sum of above-ground and underground biomass; return suspected abnormal values to the original records for review to ensure the comparability and traceability of the data.", "ds_ref_way": "", "ds_abstract": "
This dataset records the above-ground biomass, underground biomass and total biomass of leguminous and non-leguminous plants during the soil conditioning stage, plant-soil feedback stage, and under different microbial diversity treatments. Based on four gramineae species: bromus glabrous, perennial ryegrass, arrowhead and reed fescue, and four leguminous species: alfalfa, white clover, red clover and sainfoin, the experiment constructed plant communities with species richness of 1, 2, 4 and 8, and set different proportions of gramineae to legumes. The data set includes 3 worksheets: 640 pieces of biomass data for individual species in the regulation stage; 1600 pieces of data for the plant-soil feedback stage, consisting of 20 types of regulated soils, 20 types of planted plants or communities and 4 repeats; Microbial diversity processing data 480 pieces, consisting of 2 types of regulated soils, 20 types of planted plants or communities, 3 microbial diversity levels and 4 repeats. This dataset can be used to analyze the impact of plant species richness, plant functional group composition, soil carryover effects and microbial diversity on plant productivity and biomass allocation.\r\n
The \"Feedback Phase\" worksheet contains 1600 records, with the main fields including adjusted soil, soil type, planted plants or communities, species diversity, plant functional groups, homologous or heterologous soil types, aboveground biomass, underground biomass, and total biomass.
