Nectarine is more resistant to infertility and requires less fertilizer during saplings. If too much nitrogen is applied, it will easily cause lengthening and delay the result. After entering the fruiting period, as the yield increases and the growth of new shoots, the amount of fertilizer needs to increase.
Nectarine young. 1-2 years after seedling planting, it is the nurturing period of saplings, mainly based on vegetative growth. In fertilization, we must do “fat and diligence, and promote the post-controlâ€. From March to August, a decomposed manure water was applied once a month, about 10 kg per plant, and 50 g of potassium dihydrogen phosphate was added. Three years later, the nectarine entered the fruiting period, and the base fertilizer and topdressing were applied 4-5 times throughout the year. The base fertilizer is applied in September-October every year, and the amount of fertilizer applied accounts for 50%-70% of the total amount of the whole year. At Shishi, digging 1-2 fertilization nests with a length of about 1 meter and a depth of 0.3 meters at the nectarine drip line, 20 kg of high-quality organic fertilizer per plant, or 1-2 kg of decomposed oil cake. Calcium phosphate 0.5-0.8 kg mixed. After fertilization, cover the nest to fill the water. The top dressing is mainly based on the nectarine phenology, the process and the need for growth and robustness. The top dressing is carried out before the germination of the nectarine, after the flowering, during the hard core period, before the harvest and after the harvest. Among them, the hard-core period is the most important, that is, it is applied about 1 month after the full bloom period. Digging and fertilizing, 30-50 kg of water and fertilizer for each person who is rotted, and 0.3 kg of ammonium phosphate are added, and the root dressing is carried out at the same time. In the nectarine growing period from March to August, the leaves are sprayed with 0.1% green Fenwei foliar fertilizer, or 0.2% boron fertilizer, 0.3% potassium dihydrogen phosphate and 0.4% urea mixed fertilizer, sprayed every 20 days.
