配方施肥技术是根据土壤有效养分含量状况、作物需肥规律、产量指标以及肥料试验结果,并参照当年的气象预报,提出氮磷钾三要素的适宜用量和配比。适时施用,使作物高产、稳产的施肥技术。该技术近年来,在省内外有较大面积推广。我县从1983年到1985年,三年间全县有7个区(镇)14个单位进行了30多次田间对比试验,并在单、双季稻大田推广2万多亩,累积了大量水稻良种配合配方施肥法而获得增产大、效益高的科学资料。为了配合推广水稻良种(杂交稻),使之高产、稳产的目的,现将这一土壤普查应用成果配方施肥技术的调查和试验资料总结综述如下:
Formula fertilization technology is based on the status of soil available nutrients, fertilizer demand of crops, yield indicators and fertilizer test results, and with reference to the year’s weather forecast, put forward the appropriate amount and ratio of three elements of NPK. Timely application, so that high-yield crops, stable fertilization technology. In recent years, the technology has a large area of promotion both inside and outside the province. From 1983 to 1985 in our county, 14 counties in 7 districts (towns) conducted comparative experiments in more than 30 fields in three years and promoted more than 20,000 mu in single and double cropping paddy fields, accumulating a large amount of rice With the method of fertilizing the seed with formula and yield large, high efficiency of scientific information. To tie in with the promotion of rice varieties (hybrid rice), so that high-yield, stable production purposes, this soil census application results formula fertilizer technology survey and test data are summarized as follows:
