摘要
Rice cultivation in Jilin Province, China, encounters challenges associated with straw management and nitrogen fertilizer usage. This study explores the effects of dynamic nitrogen fertilizer application combined with straw incorporation on soil properties, rice yield, and quality. High-quality Japonica rice varieties, "Jihong 9″ and "Jinongda 853," were cultivated in a 3-year trial across different regions. Results showed that dynamic nitrogen fertilizer application under straw incorporation significantly improved soil properties, leading to increased yields. Over the years, the average yield in straw retuning (SR) was 10,566 kg/ha, surpassing conventional practices (CK) at 9939 kg/ha. SR exhibited higher effective tiller rates, spike numbers, and grain numbers per spike, contributing to enhanced yields. Quality analysis revealed that SR rice exhibited lower protein content, resulting in reduced chalkiness and improved taste quality, making it a more desirable option. These findings highlight the effectiveness of sustainable agricultural practices in optimizing rice production in Jilin Province.
