清徐县是我国四大葡萄产区之一,葡萄主要栽培在洪积扇边的砾质褐土、砂砾质褐土及山区砂质砾石山地褐土上,旱、涝、薄、瘦,再加上有机肥源不足,只注重氦、磷肥的施用,钾素不足已成为限制清徐葡萄生长的主要原因。我们采用钾宝进行叶面喷施,效果不错。 Qingxu County is one of the four major grape producing areas in our country. The grapes are mainly cultivated on gravelly cinnamon, gravelly cinnamon and sandy gravel mountainous cinnamon in the alluvial fan, drought, waterlogging, thin, thin, and then Coupled with the lack of organic fertilizer, only focus on the application of helium, phosphate fertilizer, potassium deficiency has become the main reason for limiting the growth of Qing Xu grapes. We use potassium Po foliar spray, the effect is good.
