Does the more potassium formate used in foliar fertilizer, the faster the fruit expands?

Nowadays, in order to save the cost of fertilizer, many peasant households simply apply fertilizer from seedling stage to pre-flowering and post-flowering stage. Some even rely on bottom fertilizer to Fruit-setting stage, and then use a large amount of high-potassium fertilizer. The result is often seedling stage, the root system is not developed, the seedling is weak and the growth is poor. It is common to use more potassium fertilizer at fruit-expanding stage. Therefore, the more potassium formate is sprayed on foliar fertilizer, the faster the fruit expands, it must be wrong.
There are many factors and elements involved in fruit expansion. In many cases, fruit growth is not large, not lack of potassium, but excessive application of potassium. As far as high potassium fertilizer is concerned, it is well known that fruit enlargement and coloration are indispensable to increase yield and harvest, but blindly applying more potassium fertilizer after fruit setting does not necessarily lead to high yield and harvest.
Potassium fertilizer that can rank first on the market is KCl<K2SO4<KNO3<K2CO3<KH2PO4<organic potassium<potassium polyphosphate. Potassium formate is one of the organic potassium fertilizers. It belongs to alkaline fertilizer, which can reduce soil acidity and provide a large amount of available carbon fertilizer. There are also many advantages: First of all, the water solubility of potassium formate needn't be said. The solubility of potassium formate increases with the increase of the atomic weight of alkali metals. The saturation concentration of potassium formate can reach 76%, and it dissolves quickly. It can improve the nutrient utilization rate, and the amount of fertilizer is less. It is suitable for the application of micronutrient fertilizer, and the effect of yield increase is remarkable.
Then, the potassium content in potassium formate is high, and the chloride ion content of harmful substances is very low. It is the best choice to produce high-potassium and high-concentration drip irrigation liquid fertilizer. It belongs to high-potassium potassium fertilizer. It can absorb completely without residue and increase the absorption efficiency of other fertilizers (mainly nitrogen fertilizer).
Potassium formate in potassium fertilizer is safe and harmless, and will not cause the deterioration of the ecological environment and improve the environmental quality. The effect of application should be analyzed in combination with the specific problems of water, temperature, crop and soil status. Observation of crop growth, understanding of soil conditions, and precise selection and application are key.
