Moderate morning application. The application of potassium chloride should emphasize an "early" word. Partial clay should be used as base fertilizer, and sandy soil and water leakage fields can be applied in several stages to reduce the loss of potassium fertilizer. Chloride ion can inhibit seed germination, reduce germination rate and emergence rate, and is not suitable for seed fertilizer. The base fertilizer is applied 7 to 10 days before sowing or transplanting, so that the soil is adsorbed, chloride ions are leached, and the root layer of the crop is reduced by chlorine.
Appropriate deep application. Most of the roots of the crops are concentrated in the soil layer of 10 to 25 cm. Therefore, the application of the base fertilizer layer, strip application and hole application should be below 8-12 cm, and the top dressing should not be shallower than 8 cm. The paddy field is covered under the water layer and has poor ventilation performance. The potassium absorption of rice needs to be carried out under aerobic conditions. Therefore, the application of potassium chloride in rice fields should not be too deep, and the base fertilizer should be applied in the 8 cm soil layer. The thin water layer should be controlled, and the water should not enter or leave the water after one week. To prevent the loss of potassium and affect fertilizer efficiency.
Nitrogen, phosphorus and potassium are combined. This is a good way to balance fertilization and improve the economic benefits of fertilization.

Applied by soil. The lower the effective potassium content in the soil, the more significant the effect of applying potassium fertilizer to increase production. Experiences from various places have shown that potassium-deficient soils with an effective potassium content of less than 80×10-6, especially those with a potassium deficiency of less than 50×10-6, have low potassium supply capacity, and the effect of applying potassium fertilizer is most significant. Although the organic matter content is high in cold soaked fields and muddy fields, but due to high groundwater level, low water temperature and poor microbial activity, the effective potassium content in organic matter is also small, so the effect of potassium application is better.
