In agriculture, potassium nitrate is used as a chlorine free water-soluble fertilizer to supplement crops with nitrate nitrogen and potassium. Agricultural potassium nitrate fertilizer is 100% plant nutrient, which is completely soluble in water without residual harmful substances.

它所含硝態氮和鉀均為農作物生長所必需的大量元素，兩者間具有良好的協調作用，可互相促進被作物吸收并促進其它營養元素的吸收；其所含的氮鉀比為1:3(一般作物都以此比例吸收氮、鉀)，可在作物需肥高峰期均衡迅速地被作物吸收利用。

The nitrate nitrogen and potassium contained in it are a large number of elements necessary for crop growth. They have good coordination and can promote each other to be absorbed by crops and promote the absorption of other nutrient elements; The ratio of nitrogen to potassium is 1:3 (generally crops absorb nitrogen and potassium in this ratio), which can be absorbed and utilized by crops in a balanced and rapid manner during the peak period of crop fertilizer demand.

農用酸鉀肥料無氯無鈉，鹽指數低；水溶性好但不吸濕，養份含量高，肥效作用迅速。使用農用酸鉀可提高產量，改善品質，提早成熟，增強抗病力，延長保鮮期。廣泛用于各種糧食作物、經濟作物；作基肥或追肥施用，特別適用于煙草。

Agricultural potassium nitrate fertilizer has no chlorine, no sodium and low salt index; It has good water solubility but no moisture absorption, high nutrient content and rapid fertilizer effect. The use of agricultural potassium nitrate can increase yield, improve quality, mature early, enhance disease resistance and prolong the fresh-keeping period. Widely used in various food crops and cash crops; As base fertilizer or topdressing, it is especially suitable for tobacco.

產品性質：農用酸鉀肥料是一種無色透明晶體或白色粉末，易溶于水，不溶于乙醇與乙醚在空氣中不易潮解。

Product properties: agricultural potassium nitrate fertilizer is a colorless transparent crystal or white powder, which is easily soluble in water, insoluble in ethanol and ether, and difficult to deliquesce in the air.

施用方法及注意事項：

Application method and precautions:

1）農用酸鉀肥料是硝態氮復合肥(煙草肥)的主要原料之一。

1) Agricultural potassium nitrate fertilizer is one of the main raw materials for the production of nitrate nitrogen compound fertilizer (tobacco fertilizer).

2）土壤施用：農用酸鉀肥料可作為基肥或追肥單獨施用；也可用作葉面噴施或與其它肥料一起籬用。

2) Soil application: agricultural potassium nitrate fertilizer can be used as base fertilizer or topdressing separately; It can also be used as foliar spraying or hedgerow with other fertilizers.

3）隨水灌施：該肥料可以與其它全溶性肥料一起隨水灌施或用作葉面噴施。

3) Irrigation with water: the fertilizer can be irrigated with water together with other fully soluble fertilizers or used as foliar spraying.

4）儲藏方法：注意防潮、防雨、防曬。

4) Storage method: pay attention to moisture, rain and sun protection.
