Yangmei is one of the earliest and most fruitful trees in spring. It is beginning to take off flower buds when it is cold in early spring, and it will bloom after harvesting. It will mature in late spring and early summer, from flowering to fruit ripening. Only 2 to 3 months. The flowers are full of trees, and the results are very heavy. Therefore, the nutrient requirements are particularly strict. It is not possible to meet the nutrient requirements by applying some pre-flowering fertilizer and strong fruit fertilizer. It is best to apply the fertilizer to be applied in the winter in advance to make the bayberry tree. There is sufficient nutrients accumulated in the body to have sufficient nutrient supply during the flowering period, ensuring more fruit, large fruit and excellent quality.
specific methods:
In the winter, under the canopy, the drip line around the canopy is dug deep and wide, 30-40 cm wide, and then each tree of five years or more is used to make 30-40 kg of decomposed human and poultry manure, NPK (15 -15-15) 2 to 3 kg of compound fertilizer, 3 to 4 kg of superphosphate or calcium magnesium phosphate, 0.5 to 1 kg of potassium chloride or potassium sulfate, 1 to 1.5 kg of magnesium sulfate, and 8 to 10 kg of biological fertilizer. After thoroughly mixing and mixing all the fertilizers, spread them evenly in the ring groove, and cover the soil to cover the fertilizer. If the weather is dry after fertilization, it is necessary to apply 80-100 kg of decomposed human and animal manure or biogas slurry or water to each tree, and evenly spread on the soil covering the ring ditch to promote the dissolution and transformation of the fertilizer and supply the roots for absorption. And use to improve the effect of fertilization.
In addition, spray the 0.1% borax, 0.1% magnesium sulfate, 0.2% urea, 0.3% potassium dihydrogen phosphate, 800 times humic acid active liquid fertilizer mixture every 10 to 15 days in the winter, and spray 3 to 5 times continuously. It evenly sprays all the branches and leaves inside and outside the canopy, and supplements various nutrients from the foliage to improve the nutrient level of the plants.
