草莓是一种喜钾作物。为了充分发挥大棚草莓生长发育期间对钾的需求,2001年无极县农技中心进行了大棚草莓叶面喷施钾肥示范,并收到了很好的效果。具体做法是:在与对照区相同的面积内,将供试验用的草莓分4次喷施1.5～2％的硝酸钾溶液,即从1月10日起每隔10天喷一次,以清水为对照,结果表明:喷施销酸钾后,草莓叶色浓缘、肥厚、光合作用
Strawberry is a hi potassium crop. In order to give full play to the demand for potassium during the growth and development of strawberries in greenhouses, in 2001, Wuji County Agronomy Center conducted demonstration of foliar application of potassium fertilizer in greenhouse and received good results. The specific approach is: in the same area with the control area, for the test strawberries were sprayed 4 times 1.5 to 2% potassium nitrate solution, that is, from January 10, spray once every 10 days, with water as The results showed that: after sprayed potassium potassium nitrate, strawberry leaf color thick edge, hypertrophy, photosynthesis
