People's Republic of China Ministry of Agriculture standards: NY1107-2010 macronutrient water-soluble fertilizer (in the amount of the element type) of a solid product, a large number of elements in the main technical indicators in the amount of element content% ≥50.0% ≥1.0 Water insoluble matter% ≤5.0PH (1: : 250-fold dilution) from 3.0 to 9.0% ≤3.0 Water soluble fertilizer large number of elements (in the amount of the element type) liquid products, the sale of a large number of elements soluble fertilizer, the main technical indicators macronutrient content g / L in the amount of element content ≥500 g / L ≥ 10 water insoluble content g / L ≤50PH (1 :: 250-fold dilution) from 3.0 to 9.0 large number of elements soluble fertilizers (trace element type) solid, water-soluble fertilizer Guizhou large number of elements, the main technical indicators macronutrient content% ≥50.0 trace elements Content% ≥0.2 ~ 3 Water insoluble matter% ≤5.0PH (1 :: 250-fold dilution) from 3.0 to 9.0% ≤3.0 Water soluble fertilizer large number of elements (trace element type) liquid products. Water-soluble fertilizer to improve soil macronutrients: Allow the soil to form aggregate structure, get rid of soil compaction, enhanced root respiratory function. Macronutrients soluble fertilizer utilization is high: soluble prompt, thorough, macronutrient soluble fertilizer specifications, with a special affinity Soil, fertilizer is not lost, utilization doubled. Macronutrients soluble fertilizer increase significantly: compared with conventional fertilizers, the same amount of administration may significantly increase. Improve the quality of the water-soluble fertilizer macronutrients: high efficiency multi-element balanced fully absorb, improve quality of agricultural products, a large number of elements soluble fertilizer manufacturers, flavor. A large number of water-soluble fertilizer, pest-resistant elements: promote skin cell wall thickening, improve the germs and sucking insect pests. Water-soluble fertilizer macronutrients strong resistance: to improve crop drought, cold, lodging, saline-alkali capacity. Water-soluble fertilizer and preservation extended macronutrients: improve agricultural anti-bacteria, anti-oxidation ability, extend shelf life and shelf life.
