Wampee fertilization can refer to the following methods:
1. Around Great Cold, apply about 12 kg of fully decomposed chicken manure with a moisture content of 10~20%. The fertilization method is to dig a ring-shaped trench about 20 cm inside and outside the drip line of the canopy, reaching a depth of 30~40 cm, and proceed by placing one layer of fertilizer and one layer of turf soil, then cover with soil after fertilization. It is also possible to dig several symmetrical holes about 20 cm inside and outside the drip line, then apply the fertilizer and cover with soil.
2. The second fertilization time is around the full bloom stage. Several holes can be dug under the drip line of the canopy, and about 200 g of 15:15:15 compound fertilizer can be applied. If the leaves are still dark green at this time and there is no obvious fading of leaf color, it indicates that the nutrients stored in the tree are relatively sufficient, so there is no need to fertilize, and instead spray foliar fertilizer on the canopy.
3. The third fertilization time is after the second physiological fruit drop. 100 g of 15:15:15 compound fertilizer and 3 kg of decomposed chicken manure with a moisture content of 10~20% can be applied. If the weather is rainless and dry at this time, dilute the decomposed chicken manure with water, add the compound fertilizer, and drench it under the drip line of the canopy.
4. The fourth fertilization time is after fruit harvest, using organic fertilizer and spraying the canopy with foliar fertilizer to continuously support the growth of new shoots.
5. If the new shoots after fruit harvest can fully mature by late September, a fifth fertilization can be applied, with 200 g of 15:15:15 compound fertilizer, to promote the second autumn shoots to sprout before mid-October. After fertilization, pay attention to removing the terminal buds of the first early autumn shoots that sprout, breaking apical dominance, and prompting the second autumn shoots to emerge on schedule.
