一、平衡施肥技术平衡施肥是通过施肥来满足作物各生育时期对养分的需求来确定施肥量。平衡施肥主要考虑作物养分的平衡,土壤自身的平衡,施肥与环境的平衡和作物所必须的养分元素之间的平衡。(一)作物所需求的养分1、有机质:氨基酸、腐殖酸、核酸等。2、无机物质:共十六种营养元素,分为大量元素(N、P、K、C、H、O)、中量元素(Ca、Mg、S)、微量元素(Cu、Fe、Mn、Zn、B、Mo、Cl)。(二)补充植物所需养分的有效途径1、增施有机肥。提高土壤中有机质及氮、磷、钾和中微量元素的贮量。
First, the balanced fertilization technology Balanced fertilization is to fertilize the crop to meet the needs of nutrients during each growing stage to determine the amount of fertilizer. Balanced fertilization mainly considers the balance of crop nutrients, the balance of soil itself, the balance between fertilization and the environment, and the nutrient elements necessary for the crop. (A) the nutrients required for crops 1, organic matter: amino acids, humic acid, nucleic acids and so on. 2, inorganic substances: a total of 16 kinds of nutrients, divided into a large number of elements (N, P, K, C, H, O), in the amount of elements (Ca, Mg, S), trace elements Zn, B, Mo, Cl). (B) an effective way to supplement the nutrients needed by plants 1, the application of organic fertilizer. Increase soil organic matter and nitrogen, phosphorus, potassium and trace elements in the reserves.
