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.

它所含硝态氮和钾均为农作物生长所必需的大量元素，两者间具有良好的协调作用，可互相促进被作物吸收并促进其它营养元素的吸收；其所含的氮钾比为1:3(一般作物都以此比例吸收氮、钾)，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.

农用酸钾肥料无氯无钠，盐指数低；水溶性好但不吸湿，养份含量高，肥效作用迅速。使用农用酸钾可提高产量，改善品质，提早成熟，增强抗病力，延长保鲜期。广泛用于各种粮食作物、经济作物；作基肥或追肥施用，特别适用于烟草。

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.

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.

施用方法及注意事项：

Application method and precautions:

1）农用酸钾肥料是硝态氮复合肥(烟草肥)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：农用酸钾肥料可作为基肥或追肥单独施用；也可用作叶面喷施或与其它肥料一起篱用。

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）随水灌施：该肥料可以与其它全溶性肥料一起随水灌施或用作叶面喷施。

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

4）储藏方法：注意防潮、防雨、防晒。

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