(4) seedling stage management: in 9-11 months after sowing, keeping the temperature at 20-25 ℃ in the daytime and 13-16 ℃ at night, spraying water every day in the first 10 days after sowing to ensure that the water content of the matrix is 90% -95%, keeping the matrix moist and the air humidity is 85-95%, and then watering once a week to permeate water to root the seeds;
keeping the average daily temperature at 0-4 deg.C in 12-1 month, watering if the matrix is too dry, keeping the matrix wet but not wet, and keeping the water content of the matrix at 60-75%;
in the second 2 months, keeping the temperature at 18-22 ℃ in the daytime and 8-12 ℃ at night, and taking out the seeds to sprout;
in 2-5 months, keeping the temperature at 20-25 ℃ in the daytime and 10-15 ℃ at night, allowing the substrate to be dry and wet and the air humidity to be 50-60%, applying the nutrient solution once every week, allowing the plants to grow rapidly, and removing weeds in time;
the nutrient solution is cake fertilizer water with the mass concentration of 12%;
shading treatment is carried out in 6-8 months, the shading rate is 50%, ventilation is carried out, plants are enabled to grow robustly, and the bactericide is sprayed once a week;
the bactericide is 800 times of solution of 70% thiophanate methyl wettable powder, or the bactericide is 500 times of solution of 75% chlorothalonil wettable powder and 0.1% potassium dihydrogen phosphate solution in a weight ratio of 1: 1.5;
before transplanting in the middle ten days of 9-10 months, keeping the temperature at 20-25 ℃ in the daytime, and keeping the substrate dry and wet at night along with the external natural temperature, wherein the air humidity is 48-55%.
The growth of oil peonies cultivated in examples 1-6 of the present invention are shown in Table 1 below.
