这项秸秆还田新技术可助力实现水稻单产和地力提升

Core Viewpoint - The autumn water cutting and burying straw returning technology significantly enhances rice yield while reducing fertilizer usage, presenting a viable solution for sustainable agriculture in Northeast China [1] Group 1: Technology Overview - The autumn water cutting and burying straw returning technology allows for rice straw to be buried in the soil after harvest, achieving a yield of 670.3 kg per mu (approximately 0.067 hectares) with a 28% reduction in fertilizer usage compared to control fields, resulting in an increase of 67.4 kg per mu [1] - This technology transforms traditional straw returning methods by utilizing the effective accumulated temperature during the 200-day fall, winter, and spring period, and creates a favorable environment for microbial activity through water-based soil preparation [1] Group 2: Development and Implementation - The technology has been developed over several years by the Chinese Academy of Agricultural Sciences, which also created supporting machinery and water-fertilizer management techniques [1] - Experts in the industry recognize that the integration of agricultural machinery and agronomy in this technology addresses significant challenges in straw returning in Northeast China, contributing to the protection of black soil and increasing rice yield on a large scale [1]
