Example Embodiment
[0026] Example 1
[0027] Step 1. Pave the high dry and sunny sandy soil 60cm in the greenhouse. The sandy soil is loose and breathable, with good drainage, and adjust the pH of the sandy soil to 6.8, the soil is deepened 30cm, 170kg cake fertilizer per mu, 40kg compound Fertilizer is used as a base fertilizer, and 10 kg of phoxim granules and 4 kg of carbendazim are applied simultaneously as a soil insecticide and fungicide;
[0028] Step 2. From mid-September to mid-October, the selected Fengdan peony plants with large seed yield, high oil yield, wide adaptability, and strong growth potential were soaked for 5 minutes with 800 times thiram for effective use of the land. After drying, plant with 30cm×50cm spacing × row spacing;
[0029] Step 3: No top dressing in the first year after planting, and top dressing twice a year in the second year. The first top dressing is applied at 60 kg compound fertilizer per mu before and after the spring equinox, and the second is applying 180 kg ...

[0031] Example 2
[0032] Step 1. Pave 80cm dry and sunny sandy soil in the greenhouse. The sandy soil is loose and breathable, with good drainage, and adjust the pH of the sandy soil to 7.5, the soil is deepened 40cm, and 1200 kg of decomposed manure per acre is applied. One kilogram of compound fertilizer is used as a base fertilizer, while 15 kilograms of phoxim granules and 5 kilograms of carbendazim are used as soil insecticides and fungicides;
[0033] Step 2: From mid-September to mid-October, soak the selected purple-spotted peony plants with large seed yield, high oil yield, wide adaptability, and strong growth potential for 10 minutes with 800 times thiram, in order to effectively use the land and dry After planting, plant spacing × row spacing of 30cm×50cm;
[0034] Step 3: No top dressing in the first year after planting, and top dressing twice a year in the second year. The first top dressing is around the spring equinox with 70 kg compound fertilizer per mu, and the se...

Abstract
The invention relates to the technical field of flower cultivation, in particular to a method for cultivating peonies for oil. The method comprises the steps that sandy soil is laid in a greenhouse, pH is adjusted, and fertilization and sterilization are carried out; selected peony plants for the oil are planted with row spacing*line spacing of 30cm*50cm; hoeing and topdressing are carried out in the growing period of the peonies for the oil, indoor air ventilation and light transmission are kept, insect killing and sterilization are carried out, chlormequat chloride is sprayed, the flower head of each plant is covered with a plastic bag for 2-3 days, and then a plurality of small holes are pricked in each plastic bag with needles; in the florescence, the plastic bags on the flower heads of the plants are removed, gibberellins and daminozide are sprayed on pistils and stamens respectively, pollinating insects are placed in the greenhouse, temperature, illumination time and ventilation time in the greenhouse are controlled, and meanwhile hand pollination is carried out; fallen leaves are swept away in time, and are burned up or buried deeply in a centralized mode. According to the method, the growing conditions of the peonies for the oil are improved, meanwhile, the pollination success rate in the florescence of the peonies for the oil is increased, and therefore the seed setting rate is improved.
Description
technical field [0001] The invention relates to the technical field of flower cultivation, in particular to a method for cultivating peonies for oil. Background technique [0002] Peony is a perennial woody plant. "Purple spot" peony is suitable for semi-arid areas in the north, while "Fengdan" peony is suitable for the Yangtze River Basin. More than 20 provinces and cities in the country are suitable for planting oil peony, with an average of 2 million mu in each province. The planting area can be up to 40 million mu, and the output of peony seeds can reach 10 million tons. my country is a country that relies more than 60% on foreign countries for edible oil crops, and urgently needs to diversify domestic oil crops. Peony edible oil is the best edible oil in the world. Peony seed oil is rich in a large amount of unsaturated fatty acids, and the content of unsaturated fatty acids is as high as 92%. In addition, peony seed oil has functions such as health care, anti-oxidati...
