配方施肥是根据作物需肥规律、土壤供肥性能与肥料效应,以必需的肥料投入而获得理想产量和良好经济效益为目标,合理确定氮、磷、钾肥以及微量元素的适宜用量和比例的综合性科学施肥技术。 在世界农业发达国家已广泛应用于农业生产中,我国也注意配方施肥技术的试验、示范、推广。据报道,1986年我国已有1300多个县推广应用配方施肥技术。取得显著成效。1986年兵团在小麦、玉米、水稻、棉花、甜菜、油葵六种作物上进行测土施肥试验、示范初见成效。农八师一四四团场在38950亩棉花、玉米、甜菜作物上合理、经济有效地施肥,每亩节省三料磷肥三公斤,共节省
Formula fertilization is based on the law of crop fertilizer, soil fertility and fertilizer effect, with the necessary input of fertilizers to achieve the desired yield and good economic efficiency as the goal, a reasonable determination of the appropriate amount and proportion of nitrogen, phosphorus, potash and trace elements Sex science fertilization technology. In the developed countries of the world agriculture has been widely used in agricultural production, our country also pay attention to the experiment of formula fertilization technology, demonstration and promotion. According to reports, in 1986 China has more than 1,300 counties to promote the application of fertilizer technology. Achieved remarkable results. In 1986, the Corps conducted soil fertilization experiments on six crops of wheat, corn, rice, cotton, sugar beet and sunflower, demonstrating initial success. Nong Bashi four hundred four field in 38950 acres of cotton, corn, sugar beet crops on a reasonable and cost-effective fertilization, saving three kilograms per mu of phosphate three kilograms, a total of savings
