Oil peony seeding culture method

Abstract

The invention provides an oil peony seeding culture method and relates to the technical field of oil peony planting. The method comprises the following steps of 1, seedling processing, wherein seeds are soaked with gibberellin of 200 ppm for 12 hours, dormant seed germination is broken, then, after wet river sand and the peony seeds are fixed uniformly, the mixture is stored in the sand, 15-20 days later, the seeds germinate, and the seeds can be sown; 2, seedling land selecting, wherein dry neutral sandy soil exposed to the sun and good in water drainage is selected, base fertilizer is adequately applied before the seeds are sown, 1000 kg of hot and humic farmyard manure or 50 kg of compound fertilizer is selected to be used as the base fertilizer, then, 10-15 kg of phoxim is added to besoil bactericide, and the soil is deeply tilled for 30-40 cm; 3, land preparing and seed sowing, wherein before the seeds are sown, the soil condition is checked, watering quantity is decided according to soil humidity, deep tillage and intensive farming are carried out, thus, the soil is loosened, and strip sowing or drilling are adopted; 4, seedling land field managing, wherein radicles grow 15-30 days later after the seeds are sown, at the end of February or at the beginning of March next year, the earth temperature is increased by 4-5 DEG C, a covering is removed, weeds are pulled up, surface soil is slightly loosened, weed shoots are removed, the land is hoed, and when the land is dry and seedlings are small, the seedlings are irrigated.

Description

technical field [0001] The invention relates to the technical field of oil peony planting, in particular to a method for raising seedlings of oil tree peony. Background technique [0002] Oil peony is a kind of Paeoniaceae plant, which is distributed in the northwest, Taibai Mountain in Shaanxi, Wanhua Mountain in Yan'an and other places. The best time for sowing seedlings is from late August to mid-September. Because the seeds of peony for oil have the characteristic of epicotyl dormancy, which is different from most other plants. This characteristic determines that the oil peony will only produce young roots at room temperature after sowing in late autumn, and the young shoots need to undergo low temperature in winter to complete the physiological changes in the dormant period, and then germinate in the following spring. If the seeds are sown in spring, only young roots can grow in that year. After meeting the low temperature conditions in winter, they can germinate in th...
