Fruit growers want to enlarge the fruit, color and sweeten it. In the early stage, the cells need to accumulate solutes to maintain the balance of water potential gradient, thus ensuring cell enlargement. The rapid expansion of cells depends on the high mobility of osmotic agents, where potassium ions play an important role. Can potassium formate, a new water-soluble fertilizer, play a role in expanding fruit? Chongqing Chuandong Chemical Group tells you.

Let's see the important physiological effects of potassium on crops:

1. Promoting Enzyme Activation

Potassium is an activator of many enzymes in plants. Oxyreductase, synthetase, transferase and phosphokinase all need potassium activation. They participate in important physiological metabolism in plants, including sugar metabolism, protein metabolism, nucleic acid metabolism and so on.

Potassium can also increase the activity of endogenous protective enzymes such as peroxidase and enhance the ability of plants to resist environmental stimuli.

2. Improve and regulate photosynthesis

Potassium can improve photosynthesis of plants, mainly in promoting stomatal opening, regulating stomatal conductance, increasing chlorophyll content and the activity of key photosynthetic enzymes.

The regulation of potassium on plant photosynthesis process is mainly embodied in: affecting the size of photosynthetic capacity; affecting the activity of photosynthetic system.

3. Regulation of osmotic potential

By changing the osmotic potential of plants, potassium forms a continuous gradient of water potential in the tree, promotes the absorption of water and the movement of water in the tree, thus creating favorable conditions for plants to synthesize more photosynthates.

Suitable potassium concentration can maintain high swelling pressure, relative water content and low osmotic potential, which is conducive to improving the ability of plants to resist drought.

4. Improving Yield and Fruit Quality

Potassium can improve the transport capacity of cell membrane and promote the transport of assimilation products, and proceed in the direction of fruit.

Therefore, high potassium foliar spraying is very useful for crops. The solid content of potassium formate is 97%, and the liquid content is about 70%.

After applying potassium formate foliar fertilizer, the content of potassium in leaves increased firstly, and then transferred to fruits to promote the growth of pulp cells, thereby promoting fruit enlargement and increasing the yield of fruit trees. It can also increase the activities of sugar metabolism related enzymes, promote the conversion of starch to sugar, and increase the total sugar content in fruits.
