Effect of different treatments of Zizania latifolia sheath leaves on the yield and quality of Zizania latifolia
In order to clarify the application methods and actual application effects of Zizania latifolia sheath leaf compost,research and demonstration on the resource utilization modes of Zizania latifolia sheath leaf,such as direct returning to the field and composting application,were carried out from 2021 to 2023.From the experimental results,it can be seen that returning the sheath leaves of Zizania latifolia to the field has a significant effect on improving the yield of Zizania latifolia.Directly returning the fresh sheath leaves of Zizania latifolia to the field can increase the average yield of Zizania latifolia by 9.09%,while returning the composted sheath leaves of Zizania latifolia to the field can increase the average yield of Zizania latifolia by 13.41%-18.94%,and the effect of high amount returning is better than that of low amount returning;Returning the composted sheath leaves of Zizania latifolia to the field can accelerate the tillering process of Zizania latifolia,increase the number of peak and effective seedlings,and enhance plant growth.During the harvest period,the shell weight and net weight of Zizania latifolia increased,which to some extent increased the yield of Zizania latifolia.After composting the sheath leaves of Zizania latifolia,double returning to the field(treatment 4)resulted in the highest plant growth,shell weight,and net weight of Zizania latifolia.Returning the composted sheath leaves of Zizania latifolia to the field can also increase soil organic content to a certain extent,but the increase is not significant.The content of alkaline hydrolyzable nitrogen,available potassium,and other nutrients in the soil significantly increased,and the soil pH value increased,which had a certain effect on alleviating soil acidification.Moreover,the effect of returning the composted sheath leaves of Zizania latifolia to the field is better than that of directly returning the fresh sheath leaves of Zizania latifolia to the field.
