Abstract

Abstract:

Straw is the main waste in agricultural production. Due to its large volume, it is difficult to collect and dispose. For a long time, it is often piled up, burned or directly returned to the field, which affects the quality of the surrounding environment. To address the challenges of agricultural straw and improve resource utilization, a straw mixed fertilizer was developed and its effects were evaluated on rice yield and soil fertility through a three-year field experiment. Results demonstrated that application of straw mixed fertilizer increased soil organic matter, available phosphorus, and potassium. Soil pH value and salinity were effectively regulated under straw mixed fertilizer treatments. Compared to other treatments, straw mixed fertilizer application achieved better rice yield. This study confirms that straw mixed fertilizer not only resolves straw disposal issues but also promotes sustainable agriculture by improving soil. Long-term effects of straw mixed fertilizer on soil fertility is still needed to be further investigated.

Key words: straw, straw mixed fertilizer, rice, applications
