1 Fertilization period Linyi Fertilizer Network Copyright
   The base fertilizer is generally made of high-quality organic fertilizer, preferably the autumn application, combined with the deep application of the soil. Topdressing is carried out in the following four periods: pre-emergence and post-flowering topdressing, mainly compound fertilizer; in the expansion period, topdressing, promoting new shoot growth and flower bud differentiation, applying appropriate amount of nitrogen fertilizer, applying more phosphorus and potassium fertilizer, mainly ternary compound fertilizer; Pre-harvest topdressing, mainly available potassium fertilizer, can promote fruit expansion and improve fruit quality, generally applied 15 days before mining; post-harvest topdressing, mainly for varieties that consume more nutrients or trees with weak trees.

2 Fertilizer amount Linyi Fertilizer Network Copyright
   Organic fertilizer as the basic fertilizer for pollution-free pomegranate, the amount of 667 square meters should be 4000~5000kg, organic fertilizer can improve soil, reduce environmental pollution, and significantly improve yield and quality. Soil testing and fertilization has a great effect on increasing fruit set rate and maintaining sustained and stable yield increase. According to the measurement, 667 square meters of 2300kg of pomegranate garden, the appropriate amount of nitrogen, phosphorus, potassium is: pure nitrogen 21.2kg, pure phosphorus 18.4kg, pure potassium 9.6kg.

3 fertilization method Linyi Fertilizer Network Copyright
   According to the characteristics of pomegranate fertilizer and the characteristics of various chemical fertilizers, it is scientifically fertilized. The saplings are applied in a circular ditch and are located at the outer edge of the canopy. Radial ditch is applied during the fruiting period. According to the distribution of the root system, the ditch should be dug into shallow (10-20 cm) and deep (30-40 cm). form. The clay soil is hard and strong, and it can be applied deep enough to guide the root system to expand deep; the sand nutrient is easy to be lost, and it should be applied shallowly. The radiation ditch should be replaced every year to achieve the purpose of land reform. Linyi Fertilizer Network Copyright
4 scientific fertilizer fertilizer fertilizer Linyi Copyright
   With the continuous improvement of pomegranate production and the repeated use of the old pomegranate garden, it is necessary to apply appropriate amounts of trace elements such as zinc and boron. Linyi Fertilizer Network Copyright
4.1 Zinc deficiency Linyi Fertilizer Network Copyright
   When the pomegranate is deficient in zinc, the spring germination is later, the leaves are small, the fruit is small, the crown is sparse, and the yield is very low. Preventive measures: 1) Soil application. Combined with fertilization strain application of 0.1 kg of zinc sulfate, this method has a long effective period. 2) Foliar application. Spray zinc sulfate solution (zinc sulfate lkg, quicklime 0.7 kg, water 200 kg) 1-2 times before flowering for 2-3 weeks. Linyi Fertilizer Network Copyright
4.2 Boron Boron Linfen Fertilizer Network Copyright
When the pomegranate is deficient in boron, the top tip has irregular gangrene, the leaves are yellow, and the top tip is withered. Precautions: Spray 0.2% borax or 0.1% boric acid 2-3 times before and after the initial flowering period, or apply 20 g of borax to the fertilization plant. Micro-fertilizer root application should generally be combined with spring fertilizer or autumn fertilizer, and pay attention to the amount can not be too much, so as not to cause fat damage.
