依据土壤养分丰缺指标,对秀洲区1 866个稻田土样有机质、碱解氮、有效磷和速效钾含量等4个养分性状进行归类分析,初步探清全区各镇稻田4个养分性状的区域分布特点及其原因,并根据秀洲区农业生产实际和土壤养分区域分布现状,提出多途径秸秆还田、利用多种有机肥源、加强翻耕和中耕松土、应用测土配方施肥技术等科学施肥和地力培肥措施。
According to the indexes of soil nutrient abundance and deficiency, this paper classified and analyzed 4 nutrient traits of 1 866 paddy soils in Xiuzhou District, including soil organic matter, available nitrogen, available phosphorus and available potassium, According to the actual situation of agricultural production and the distribution of soil nutrient in Xiuzhou district, we put forward the multi-way straw returning, using multiple organic fertilizer sources, strengthening the tillage and cultivating the loose soil, applying the soil testing formula Fertilization technology and other scientific fertilization and fertility fertilization measures.
