Banana is a fruit tree that loves potassium. Of the nutrients absorbed during its growth and development, potassium is the most abundant. If the potassium supply is insufficient, bananas will grow poorly, showing weak plants that topple easily, small buds, thin fruit, low yield, poor quality, poor tolerance for storage and transport, easy rotting, weak disease resistance, and easy infection by leaf spot disease. Banana plants absorb the most potassium fertilizer before bolting, so attention should be paid to increasing the application before bolting.
From the time banana plants survive after planting and begin to send out the first new leaf until bolting and flowering, potassium fertilizer must be applied once every 15-20 days, with 100-200 grams of potassium chloride or potassium sulfate per plant each time. After broadcasting the potassium fertilizer around the banana plants, scoop a small amount of thin mud from the furrow to cover the potassium fertilizer, or dilute it with 10-15 kg of clean water and drench it around the plants. In addition, a 0.2-0.3% potassium dihydrogen phosphate aqueous solution, or a 500-600 times high-efficiency biological phosphorus-potassium fertilizer aqueous solution, must be sprayed on the leaves once every 10-15 days, evenly wetting all the leaves, to supplement potassium fertilizer from the leaf surface. This is beneficial for the normal growth of banana plants, increases the potassium content in the plants, promotes bolting and flowering, and improves yield and quality.
