Abstract

Abstract:

To clarify the influence mechanism of biochar types and application rates on rice growth and optimize its field application, this study used four distinct biochar (rice hulls, coffee residue, peanut hulls and soybean straw) as materials, and set 0%-5.0% gradient application rate to analyze its effect on the growth and development of rice (Oryza sativa L. ). The findings demonstrated that biochar significantly promoted rice growth. However, the optimal biochar type and biochar application rate were found to vary. In comparison with the control group, the total dry weight of the biochar treatment group exhibited an average increase of 70.3%, with rice husk biochar and coffee grounds biochar demonstrating the highest increases at an application rate of 5.0%. The impact of biochar on the various growth components of rice plants exhibited variability. The leaf mass fraction generally increased, while the stem and root mass fractions were relatively stable, and the root dry matter content was significantly increased ( e.g., the rice husk biochar treatment group increased by 7.8 % ). In addition, all biochar increased leaf mass per unit area, indicating that they may promote yield increase by enhancing photosynthetic efficiency. Studies have shown that the growth-promoting effect of biochar on rice is regulated by both species and application rate. It is necessary to optimize the application scheme in combination with crop demand and soil conditions to fully tap its sustainable application potential in green agriculture.
