Experiment on Reducing and Enhancing the Efficiency of Chemical Fertilizers through the Incorporation of Fresh Green Manure in August Melon Orchard,Dejiang County
This study explores the impact of incorporating fresh green manure into the soil on orchard yield,income,and soil quality at the August melon orchard in Dejiang County.The experiment utilized jack bean as the green manure crop.Four fertilization treatments were implemented:optimized fertilization without green manure incorporation,and reduced fertilization with crushed green manure incorporation at reductions of 5%,10%,and 15%.Each treatment was replicated three times,maintaining consistent other cultivation practices across all treatments.Results indicated no significant differences in yield among the repetitions;however,there were significant differences between treatments,with yields showing significant increases over time:Treatment 2 progressed from no significant increase to a highly significant increase,Treatment 3 from a decrease to a significant increase,and Treatment 4 from a decrease to a non-significant increase.The incorporation of crushed green manure into the soil has enhanced the soil quality of the August melon orchard.Additionally,the use of green manure enabled a 15%reduction in chemical fertilizer input,and after two years,all treatments involving green manure incorporation achieved increased income.
