生物钾肥是一种硅酸细菌。新疆土壤中虽然含有丰富的钾资源，但土壤多属盐碱土且碱化程度偏高，溶重偏大，多被土壤固定，而难以被植物吸收利用。土壤中速效钾的缺乏，已成为限制作物优质高产的一大因素。1995－96年两年在147团13连每亩以1公斤生物钾肥拌种，并在小麦追肥中亩施1公斤生物钾肥，和其它肥料拌匀混施进行对比试验。结果表明每穗粒数增加3．4─1．2粒，千粒重提高1．2－0．8克，单产提高48．3－73．6公斤，土壤中碱解氮提高4．3－5．4％，速效磷提高7－17．5％，速效钾提高5．78－8．27％。
Bio-potash is a silicic acid bacterium. Xinjiang soil, although rich in potassium resources, but most of the soil is alkaline and alkaline alkalinity, dissolved weight is too large, mostly by the soil fixed, and difficult to be absorbed by plants. The lack of available potassium in soils has become a major factor limiting the high yield of crops. In 1995-96 two years in the 147 group 13 even 1 kilogram per acre bio-potash seed dressing, and in the top dressing of wheat fertilizer 1 kg of bio-potash fertilizer, and other fertilizers mix well for comparison tests. The results showed that the number of grains per spike increased 3.4 ─ 1.2 grains, 1000-grain weight increased by 1.2-0.8 grams, yield increased 48.3-73.6 kg, soil nitrogen up 4.3-5. 4%, available phosphorus increased 7-17.5%, available potassium increased 5.78-8.27%.
