The main reason for the cracking of jackfruit is that the fruit of the jackfruit is large, and the skin becomes thinner during the expansion and maturity, and it encounters high temperature and rainy weather. If you pay attention to the supplement of phosphorus, potassium, calcium and magnesium fertilizer when applying strong fruit fertilizer, you can obviously reduce the cracking fruit. The specific practices are as follows: When the size of the jackfruit fruit is large, the fruit fertilizer is applied, and the high-quality organic fertilizer, biological bacterial fertilizer and NPK fertilizer are mainly used to increase the application of phosphorus, potassium, calcium and magnesium fertilizer. The result tree of 5 years old or more, or more than 25~30 trees of fruit, 15~20 kg of manure and poultry manure per plant, 2.5~3 kg of compound biological fertilizer, NPK (15-15-15) ) 0.75~1 kg of potassium sulfate or sulphur-sulfur or pure sulphur-based compound fertilizer, 0.5~0.75 kg of calcium ammonium nitrate, 1~1.5 kg of superphosphate or calcium magnesium phosphate, 0.25~0.5 kg of magnesium sulfate, 0.5~0.75 of potassium sulfate kg. After thoroughly mixing and mixing all the fertilizers, dig 6~8 radioactive ditch 80~100cm long, 25~30cm wide and 15~20cm deep under the canopy, spread the fertilizer in the radiation ditch, cover the soil Just fine. If the weather is dry after the jackfruit is fertilized, it is necessary to apply 50~60 kg of clear water or biogas slurry or decomposed manure and manure water to each tree, and evenly apply it to the soil covering the radiation ditch, so that the water completely penetrates into the soil. The outflow is suitable to promote the dissolution and transformation of fertilizer, accelerate the absorption and utilization of roots, and improve the application effect of strong fruit fertilizer. In addition, the leaf surface should be sprayed with 800~1000 times Xingpeng Phosphorus Potassium No.1, 800~1000 times Xingpeng Calcium and Magnesium No.1, 600~800 times amino acid active liquid fertilizer mixed solution, or 0.1% magnesium sulfate, 0.3% dihydrogen phosphate Potassium, 800 times humic acid active liquid fertilizer, 1000 times chelated calcium mixture, spray once every 10~15 days, spray 2~3 times continuously.
