Embodiment 1
[0027] Step 1. Lay 60cm of high-dry and sunny sandy soil in the greenhouse. The sandy soil is loose, breathable, and well-drained. Adjust the pH of the sandy soil to 6.8. Plow the soil 30cm deep. Apply 170 kg of cake fertilizer per mu and 40 kg of compound fertilizer. Fertilizer is used as base fertilizer, and 10 kg of phoxim granules and 4 kg of carbendazim are applied simultaneously as soil insecticide and fungicide;
[0028] Step 2. From mid-September to mid-October, soak the selected Fengdan peony plants with 800 times of thiram for 5 minutes. In order to effectively use the land, let them dry in the air. After drying, the plant spacing × row spacing is 30cm × 50cm and planted;
[0029] Step 3: No topdressing in the first year after planting, and topdressing twice a year from the second year. The first topdressing is around the vernal equinox, with 60 kg of compound fertilizer per mu, and the second time before winter, 180 kg of cake fertilizer per mu. , 20 kg of compound...
Embodiment 2
[0032] Step 1. Lay 80cm of high dry and sunny sandy soil in the greenhouse. The sandy soil is loose and breathable, well drained, and the pH of the sandy soil is adjusted to 7.5. The soil is deeply plowed by 40cm. One kilogram of compound fertilizer is used as base fertilizer, and 15 kilograms of phoxim granules and 5 kilograms of carbendazim are applied simultaneously as soil insecticide and fungicide;
[0033] Step 2. From mid-September to mid-October, soak the selected purple spot peony plants with large seed setting, high oil yield, wide adaptability and strong growth potential with 800 times thiram for 10 minutes. In order to effectively use the land, dry them in the air Afterwards, the plant spacing × row spacing is 30cm × 50cm for planting;
[0034] Step 3: Do not topdress in the first year after planting, and topdress twice a year from the second year. The first topdressing is around the vernal equinox, and 70 kg of compound fertilizer is applied per mu, and the second...

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...
