生物钾肥是由河北省科学院从玉米根际土壤中分离筛选出解钾能力很强的“146”、“114”硅酸盐细菌,并综合从中国科学院引进的“152”菌株,以制成可在大田应用的硅酸细菌肥料。为探索生物钾肥在我市自然条件下对农作物的增产作用,在棉花、芝麻、西瓜、番茄等作物上进行了生物钾肥的试验与示范工作,增产效果明显。一、增产效果(一)在棉花上的应用根据马湾镇南阐村棉花施用生物钾肥试验结果:前期施与不施生物钾肥生育差异不太明显,但后期差异显著。8月13
Biological potassium fertilizer is from Hebei Province Academy of Sciences from the corn rhizosphere soil isolated from the strong ability to solve potassium “146”, “114” silicate bacteria, and integrated from the Chinese Academy of Sciences introduced “152” strains to be made of Silicate bacteria fertilizer applied in the field. In order to explore the effect of bio-potash fertilizer on crop yield increase in our city under natural conditions, experiments and demonstration experiments of bio-potash fertilizer on cotton, sesame, watermelon, tomato and other crops were carried out, and the yield increase effect was obvious. First, the effect of increased production (A) the application of cotton According to the Ma Wanzhen Nanxiancun cotton application of bio-potash test results: pre-application and non-application of bio-potash fertility difference is not obvious, but significant differences in the late.
