Moisture management : In addition to temperature, moisture is an important factor affecting the germination of ginger lotus bulbs. Sufficient water must be supplied after planting until germination to maintain soil moisture, otherwise it will not only delay germination, but also delay flowering due to slow plant growth, reducing cut flower and bulb yield. In the middle of growth, you must maintain a moist environment, but not water. Because flowers are susceptible to bacteria, plants are best grown in a waterproof and well-drained area.
Fertilizer management : After the germination of ginger lotus, flowering, bulbous hypertrophy and germination of the next generation of sprouts are carried out simultaneously.
Fertilizer demand is high throughout the growing season. The practice of this base is: 15 kg of nitrogen, phosphorus and potassium fertilizers per plant (equivalent to 71.4 kg of ammonium sulfate, 83 kg of national phosphoric acid lime, 25 kg of potassium chloride) as base fertilizer, and every 20 days after planting. Topdressing, each application of 2 kg of nitrogen, phosphorus and potassium fertilizer (equivalent to 9.5 kg of ammonium sulfate, 11.1 kg of superphosphate phosphate, 3.3 kg of potassium chloride), it is best to use drip irrigation and apply 3% trace elements. The flowers opened in this way are thick and keep it for a long time.
Shading treatment : After the germination and the flower stems are extracted, the shade of the shading net with a shading rate of 50-60% can increase the length of the stems and the bracts, reduce the green spots at the end of the bracts, and improve the quality of the cut flowers. However, after the end of August, the plants should be removed from late August to early September due to the dense growth of the plants, mutual shade, and even higher inflorescence, and the peduncle will become thinner.
