【 摘 要 】

A study was conducted toassess the effects of a bio-fertilizer and aninorganic fertilizer on growth, yield ofspinach vegetable, on four cultivated soils,representing different agro-ecological zonesof Chengdu, Hunan, Xiaotangshan andShaanxi. Three replicates soil samplesmixed with bio-fertilizer 100 g per pot andnutrient solution (MgSO4, Ca(NO)2, KNO3)633 ml based on container volume. Spinachseeded directly ten per pot, thinned to fivewatered to plant water requirement untilmaturity. RCBD of three replication used,data for growth, yield and other agronomiccharacters and soil physicochemicalproperties evaluated. Soil results showedsubstantial differences in physicochemicalproperties from the four agro-ecologicalzones (Ferrod Arenosol, Entisol, Aridisoland Vertisol). Plant emergence percent wereXiaotangshan (74.8%), Chengdu (74.5%),Hunan (72.4%) and Shaanxi (70.7%), plantheight at six week, Xiaotangshan (17.8 cm),Hunan (17.1 cm), Shaanxi (16.8 cm) andChengdu (16.1 cm) the least, number ofleaves at six weeks were Xiaotangshan (21),Hunan (19) and (16) Shaanxi, leaf areaHunan (89.5 cm²), Shaanxi (83.7 cm²),Chengdu (79.4 cm²) and Xiaotangshan (78.1cm²), dry biomass of 4.88, 4.35, 3.83 and3.03 g obtained for Hunan, Chengdu,Shaanxi and Xiaotangshan, respectively.Percentage plant emergence based on soillayers were 0-25 cm (75.8%), 25-50 cm(75.3%), 50-75 cm (71.6%) and 75-100 cm(69.6%), respectively; highest plantemergence percentage were obtained fromtop soil layer of Hunan, treated with biofertilizer. Substantial differences wereobserved for plant height, biomass and otheragronomic characters in all the soils. Theresults show that Hunan soil is the mostsuitable for cultivation of spinach under biofertilizer treatment, compared to other types.The study underpins the importance soil types and fertilizer evaluation for asustainable vegetable production in China.
