本文根据硅酸盐菌剂即生物钾肥具有分解和氧化土壤硅酸盐矿物，破坏矿物晶体构造，转化土壤中无效钾的机能，于１９９２～１９９４年进行了生物钾肥对冬小麦生长发育与产量效应的试验研究。探讨出以播前拌种返青沟施是促使小麦促根、增蘖、抗寒、抗干热风、增穗、增粒、增重，提高缺钾麦田再创高产的重要途径。 According to the fact that bio-potash fertilizer, which is a silicate bactericide, has the functions of decomposing and oxidizing silicate minerals, destroying the crystal structure of minerals and transforming the available potassium in soil, the effects of bio-potash on the growth and yield of winter wheat were studied from 1992 to 1994 Experimental Research. Explore the sowing before sowing ditch is to promote the promotion of wheat root, tillering, cold, dry and hot wind, by ear, grain, weight gain, increase wheat yield an important way to re-create high yield.
