When the swell is in the mature stage, it is prone to cracking in the spring, and it is prone to cracking, reducing the accumulation of sugar, reducing the sugar content of the fruit, making the fruit taste lighter and of poor quality. If organic fertilizer, phosphorus and potassium fertilizer and calcium fertilizer are added during this period, it can effectively prevent cracking, promote sugar synthesis and accumulation, increase the sugar content of the fruit, and make the fruit sweet. The specific practices are as follows:
When the loquat fruit begins to expand, apply a fertilizer, 15 to 20 kg of decomposing human and poultry manure per plant, 1.5 to 2 kg of superphosphate or calcium magnesium phosphate, 0.5 to 1 kg of potassium chloride or potassium sulfate, Calcium nitrate 1 ~ 1.5 kg, around the canopy drip line digging deep, wide 25 ~ 30 cm of the annular groove, all the fertilizer is fully stirred and mixed evenly, spread in the ring groove, cover the soil. In addition, during the expansion and ripening of the loquat fruit, 0.3% potassium dihydrogen phosphate, 0.5% calcium nitrate and 800 times Gaomei humic acid active liquid fertilizer mixture should be sprayed every 10-15 days, and sprayed continuously for 5-6 times. Evenly spray all the branches and fruits inside and outside the canopy, it is advisable to start dropping with water drops, supplement the organic matter, phosphorus and potassium fertilizer and calcium fertilizer from the foliage, improve the nutrient level of the plant, and help the fruit to expand, crack and increase. Sweet, increase yield and improve quality.
