How to apply shed nectar

How to Apply Nectar Fertilizer Nectarines are a popular fruit during the winter and spring seasons, and proper fertilization in greenhouse conditions is essential for a successful harvest. Poor management can lead to significant financial losses for farmers, making it crucial to understand and implement effective fertilization techniques. Fertilization should be based on available nitrogen sources, combined with phosphorus and potassium, along with appropriate amounts of biological bacterial fertilizer. Depending on the fruiting stages, fertilization can be divided into three main phases: pre-fruit fertilizer, fruit development fertilizer, and post-harvest recovery fertilizer. 1. **Pre-Fruit Fertilizer (Detoxification Fertilizer):** This stage occurs when the fruit begins to grow rapidly, and the plant enters its active fruiting period. At this time, the stems and leaves also start to develop more vigorously, requiring additional nutrients. The first top-dressing, known as detoxification fertilizer, is critical. A recommended application is 30–40 kg of ammonium sulfate or 15–20 kg of urea per 667 square meters. 2. **Fruit Development Fertilizer (Full Fruit Fertilizer):** During the fruit enlargement phase, which is the peak growth period, the second top-dressing is applied. This fertilizer should mainly consist of quick-release nitrogen, along with phosphorus and potassium. It's also important to apply foliar sprays containing medium and trace elements like calcium, boron, and zinc. Combined with irrigation, you can use 1,000 kg of diluted human urine or 20–30 kg of diammonium phosphate per 667 square meters. 3. **Post-Harvest Recovery Fertilizer (Starry Fertilizer):** From the second top-dressing until 10 days before the final harvest, it’s advisable to apply fertilizer every 10 days, for a total of 5–6 times. Using a combination of liquid fertilizer and diluted urine can help restore the tree’s vitality. 4. **Foliar Fertilizer:** Starting from the early fruiting stage, you can spray solutions such as 0.2%–0.3% urea, 0.2%–0.3% potassium dihydrogen phosphate, and 0.1%–0.2% magnesium sulfate. These sprays should be applied every 7–10 days, usually 2–3 times depending on the plant's condition. 5. **Biological Bacterial Fertilizer:** High-quality biological bacterial fertilizer contains numerous beneficial bacteria that fix nitrogen, solubilize phosphorus, and release potassium, along with organic matter, humic acid, and trace elements. When used alongside other fertilizers, it helps reduce overall fertilizer use, improves soil structure, and increases microbial activity. By following these fertilization methods, most growers can achieve better yields, improved fruit quality, and increased profitability. With proper care and attention, nectarine cultivation can become both efficient and highly rewarding.
