鉀肥的功效鉀是农作物所需要的肥料三要素之一。鉀对植物所起的作用,主要是协助植物叶子上糖类和淀粉的形成,使作物的茎杆坚挺,增强作物适应不良的自然环境,抵抗旱灾、銹菌和其他疾病的能力。鉀在自然界中分布很广,在土壤中鉀(氧化鉀)的含量是相当多的,通常都在1—2.5％左右,不过,能为植物所利用的鉀却不多。土壤中鉀的化合物可以分为三种:水溶性鉀、吸收状态的鉀和無水矽酸盐中的鉀。其中水溶性鉀最容易为植物所吸收和利用,吸收状态的鉀也比較容易轉变为水溶性鉀供給植物的需要,而無水矽酸盐中的鉀一般不容易溶解,不容易为植物所吸收和利
Potassium Potassium Potassium is one of the three elements needed for crops. The role of potassium in plants is mainly to assist in the formation of sugars and starch on the leaves of plants, to strengthen the stalks of crops, to enhance the ability of crops to adapt to poor natural conditions, and to resist drought, rust, and other diseases. Potassium is widely distributed in nature. The content of potassium (potassium oxide) in the soil is quite large, usually about 1-2.5%. However, there is not much potassium that can be used for plants. Potassium compounds in the soil can be divided into three types: water-soluble potassium, potassium in the absorption state, and potassium in the anhydrous silicate. Among them, water-soluble potassium is most easily absorbed and utilized by plants, and potassium in the absorption state is also relatively easy to be converted into a water-soluble potassium-supplying plant. Potassium in anhydrous citrate is generally not easily dissolved and is not easily absorbed by plants. Heli
