The mass spectrometric detector is adopted for determining the nature, the resolution ratio is high, and the anti-interference capability is high; the pressure solvent extractor is used for extracting soil samples, operation is convenient, and the automation degree is high; soil pollution investigation, risk assessment and repair evaluation can be met.

Slow-release lose-control ammonium phosphate compound fertilizer and preparation method thereof
The invention discloses a slow-release lose-control ammonium phosphate compound fertilizer and a preparation method thereof (sulfenyl diammonium phosphate) which are designed for solving the problem that the traditional fertilizer is low in use ratio. The compound fertilizer provided by the invention comprises the following components by weight percent: 1-30% of nitrogenous fertilizer, 1-50% of phosphatic fertilizer, 1-40% of sulfate fertilizer, 0.1-1.0% of compound sodium nitrophenolate, 0.1-1.0% of AD-6, 1-40% of organic matter, 1-40% of compound amino acid and 1-50% of humic acid. After the fertilizer is used, the fertilizer efficiency in the early stage is quick, the fertilizer efficiency in the medium stage is stable, and the fertilizer efficiency in the later stage is long-term. By only using the fertilizer as a base fertilizer or seed bed fertilizer for one time before ploughing and sowing, fertilizer nutrients are slowly released into the soil and the fertilizer efficiency can last for months which can meet the demand on nutrient of crops in different growth periods. The compound fertilizer is an environment-friendly fertilizer, is harmless to crops, and can be used for reducing the pollution of a chemical fertilizer on soil and underground water, reducing the content of nitrate in vegetable by 80-90%, and simultaneously increasing the contents of sugar and vitamins in vegetables and fruits.
