生物钾肥即硅酸盐细菌肥料,它具有解钾、解磷,固氮多种作用,能有效地缓和钾肥的供需矛盾。根据我县近两年大区试验示范,采用拌种,基施或追施等方法,亩施0.75公斤的生物钾肥与亩施7.5公斤的氯化钾,具有相仿的增产效应。用生物钾肥比对照不施钾增产幅度为水稻6％左右,棉花10％左右,西瓜15％左右。1、水稻施用生物钾肥后,叶色深绿,分蘖速度快,早发苗多,成穗率高,熟相好,根据统计汇总,早稻坐物钾肥区亩产452.8公斤,氯化钾区亩产443.75公
Potassium bio-fertilizer that is silicate bacterial fertilizer, which has potassium, phosphorus, nitrogen fixation a variety of roles, can effectively ease the contradiction between supply and demand of potash. According to our county in the past two years, large-scale experimental demonstration, the use of seed dressing, basal or topdressing and other methods, 0.75 kg of potassium fertilizer and potassium Kushu 7.5 kg of potassium chloride, with a similar yield-increasing effect. Compared with the control, the biological potassium fertilizer did not apply potassium, the yield was about 6% of rice, about 10% of cotton and about 15% of watermelon. 1, rice after application of bio-potash, the dark green leaves, tiller speed, early seedling more, into a high rate of spike, cooked phase, according to statistical summary, early rice crop potash area per mu 452.8 kg, potassium chloride area mu 443.75 male
