摘要
测土施肥是提高农作物产量、降低农业成本、节约资源、减少污染的重要举措,我国的土壤测试采用的是常规方法,耗时长、费力大、成本高,已经不适合目前我国高投入的农业生产水平,发达国家采用的联合浸提剂一次浸提可以用于十几个甚至几十个元素的测定,大大节省了操作步骤,实现了土壤测试的批量化、快速化。我国必须引进和发展一种速度快、价格低廉,适合我国的测试方法才能广泛应用于农业生产。该研究通过阐述我国化肥工业的现状以及国内外测土施肥的发展,总结了联合浸提剂在我国测土施肥中的应用与发展前景。
Soil testing and fertilizer recommendation is an important measure to raise the crop output,reduce the agricultural costs,conserve resources and reduce pollution.The conventional methods are used in China＇s soil tests.They are time-consuming,laborious and costly,and they do not fit the current agricultural production level with high investment in China.Universal extractant in an extraction used in developed countries can be used for the measurement of more than a dozen or even dozens of elements,which greatly simplified operation steps and implemented the bulk soil testing rapidly.A fast and inexpensive method of testing that can be widely used in agricultural production should be introduced and developed in China.The current status of China＇s chemical fertilizer industry and the development of soil testing and fertilizer recommendation at home and abroad were described.The application and development prospects of universal extractant in Chinese soil testing and fertilizer recommendation were sum up.
