土壤和肥料是作物生长的决定因素,测土配方施肥是促进作物增产增收的有效措施,它是以土壤测试和肥料田间试验为基础,根据作物需肥规律、土壤供肥性能和肥料效应,在合理施用有机肥料的基础上,提出氮、磷、钾及中、微量元素等肥料的施用数量、施肥时期和施用方法。有针对性地补充作物所需的营养元素,实现各种养分平衡供应;合理施肥能提高肥料利用率和减少用量,提高作物产量,有利促进经济合理使用肥料,达到既增加产量又降低成本,对促进
Soil and fertilizer are the determinants of crop growth. Soil testing and formula fertilization is an effective measure to increase crop yield and income. It is based on soil testing and field trials of fertilizers. According to the rule of crop fertility, soil fertility and fertilizer effect, Based on the rational application of organic fertilizers, the application quantity of nitrogen, phosphorus, potassium, medium and trace elements fertilizers, fertilizing time and application method were put forward. Targeted to supplement the nutrients needed for crops to achieve a variety of nutrient balance supply; rational fertilization can increase fertilizer utilization and reduce the amount of increased crop yield, and promote the rational use of fertilizers to achieve both increase production and reduce costs, the promote
