How to fertilize loquat to prevent fruit cracking and increase sweetness?
The fruit-swelling and ripening period of loquat coincides with the rainy spring season, making fruit cracking more likely, reducing sugar accumulation, lowering the sugar content of the fruit, making the fruit taste bland and the quality poor. If organic fertilizer, phosphorus and potassium fertilizer and calcium fertilizer are applied additionally during this period, fruit cracking can be effectively prevented, and sugar synthesis and accumulation can be promoted, raising the sugar content of the fruit...

The fruit-swelling and ripening period of loquat coincides with the rainy spring season, making fruit cracking more likely, reducing sugar accumulation, lowering the sugar content of the fruit, making the fruit taste bland and the quality poor. If organic fertilizer, phosphorus and potassium fertilizer and calcium fertilizer are applied additionally during this period, fruit cracking can be effectively prevented, and sugar synthesis and accumulation can be promoted, raising the sugar content of the fruit and making the fruit sweeter. The specific method is as follows:
When the loquat fruit begins to swell, apply fertilizer once: per tree, apply 15-20 kg of rotted and decomposed human, poultry and livestock manure, 1.5-2 kg of superphosphate or calcium magnesium phosphate fertilizer, 0.5-1 kg of potassium chloride or potassium sulfate, and 1-1.5 kg of calcium nitrate. Dig a ring-shaped trench 25-30 cm deep and 25-30 cm wide around the drip line of the canopy, thoroughly stir and mix all the fertilizers evenly, spread them in the ring trench, and cover with soil. In addition, during the fruit-swelling and ripening period of loquat, spray the foliage once every 10-15 days with a mixture of 0.3% monopotassium phosphate, 0.5% calcium nitrate and 800-fold Gaomeishi humic acid active liquid fertilizer, spraying 5-6 times in succession, evenly wetting all branches, leaves and fruits inside and outside the canopy, until water droplets begin to drip down. This supplements organic matter, phosphorus and potassium fertilizer and calcium fertilizer through the leaves, raises the nutritional level of the plant, and is beneficial for fruit swelling, crack prevention and sweetening, increasing yield and improving quality.
