Techniques for cultivating peony

1. Selection of seedlings: Select plants that grow robustly, flower buds are full and more than three years old, and each plant should have more than 5 branches. Intensive management during the growing season, remove excess root pods and flower buds to remove residual flowers in time, with emphasis on fertilizer and water.
2. Seedlings and pots: When the seedlings are lifted, try to ensure that the roots of the plants are intact and dry them so that the roots become soft. The upper pots are suitable for 42-56 days before the Spring Festival. Basin diameter 25-30 cm, depth 35-40 cm, pots Loose soil, good permeability, neutral or alkaline. Usually 1/3 of coarse sand, shredded pond mud and humus soil.
3. Management: (1) Slow seedlings: water the seedlings in the first 3 days after planting, then water 6-8 times per day, and the temperature is above 10°C.
(2) Sprouting and budding stage: Remove ineffective buds as soon as possible, still spraying water 6-8 times per day, the temperature should not be too high, this stage is about 4 days.
(3) Alice, bud stage, (about 5 days) buds higher than the tip and continue to elongate, the stalk sequence is obvious. The external influence of this period is the greatest, and it is a dangerous period. It should maintain the relative stability of the environment such as wind protection, heat preservation, and moisture retention. At the same time, remove too many buds, remove the sprouts at the base, remove some of the leaves so that the nutrition is concentrated in the buds. Use 200-600ppm of "900" buds, once every morning and evening. Spray the fertilizer once every three days.
(4) Bud enlargement (about 10-13 days). Try to ensure that the temperature gradually rises and the temperature gradually drops (3 to 4 times a day). Increase the light, the temperature is suitable for 10-18 °C, less than 10 °C will not bloom. Observe the changes in the growth period. If the flowering period is too early, you can deactivate the "920" by slightly reducing the temperature and light. If the flowering period is too late, you can warm up and light up and spray 3000 times "love more to receive" solution and paint "920".
(5) Breakthrough period: The flower buds are bright and lustrous. At this time, it is close to flowering. If it is too early, it can be placed in the cold room. Too late to spray warm water plus light to promote open. After half-opening, it can extend the flowering period if it is placed at a low temperature. If the sticks are cut into the foaming water, the base of the burned red strips will be burned to avoid nutrient release. Then every five sticks are inserted into the moist basin to make a potted flower appreciation.
