江汉棉区棉田集中分布在汉江两岸,土壤质地偏砂,速效钾含量低。为了解决棉田缺钾问题,对棉田施用生物钾肥,取得明显效果,每0.5～1kg生物钾肥的增产效应相当于10～15kg氯化钾肥。每公顷施7.5～15kg生物钾肥,皮棉产量比对照田增产
Jianghan cotton area concentrated in the cotton fields across the Han River, the soil texture of sand, low available potassium. In order to solve the problem of potassium deficiency in cotton fields, bio-potash fertilizer was applied to the cotton fields and the obvious effect was achieved. The yield-increasing effect of bio-potash fertilizer of 0.5-1kg was equivalent to 10-15kg of potassium chloride fertilizer. Applied 7.5 ~ 15kg bio-potash per hectare, lint yield increased compared with the control field
