Embodiment 1
[0019] The invention provides a technical solution:
[0020] A method for growing seedlings of peony 'Fengdan' seeds for oil, comprising the following steps:
[0021] Step 1: Seed disinfection, soaking, and sand storage. Pick out and discard the seeds with diseases, insect pests and moldy, and disinfect the seeds: first use the disinfectant diluted 1000 times with 50% carbendazim wettable powder and 2000 times with 95% sulfonate wettable powder, and then rinse with water, and remove the seeds , wash with water, so that there is no disinfectant residue on the surface of the seeds. Next, soak the seeds in warm water at 45° (at this time, the seeds are layered and appear to float and sink, which is mainly due to the different water content of the seeds, and there is no need to sort the seeds), soak the seeds for 2 days, and remove all the seeds on the third day , use 200mg / ml gibberellin to treat the seeds of Fengdan peony with water, wash them, and continue to soak the seeds i...
Embodiment 2
[0025] The invention provides a technical solution:
[0026] A method for growing seedlings of peony 'Fengdan' seeds for oil, comprising the following steps:
[0027] Step 1: Process the seeds step by step. After getting the seeds, it is necessary to carry out preliminary disinfection on the seeds. When performing preliminary disinfection on the seeds, first dilute 1000 times with 50% carbendazim and 90% disulfone wettable powder Disinfect the seeds with 2000 times of disinfectant, take out the seeds, wash them with clean water, so that there is no residual disinfectant on the surface of the seeds, and then use warm water to soak the seeds, and place the seeds in 45 ° warm water for soaking (at this time, the seeds will float and sink. This is mainly due to the difference in the water content of the seeds, but there is no need to sort the seeds), soak the seeds for 2 days, remove the seeds on the 3rd day, use 200mg / ml gibberellin seeds to wash, and continue to use clean water S...

Abstract
The invention relates to the technical field of seed seedling raising, in particular to a seedling raising method for paeonia suffruticosa 'paeonia ostii' seeds, which comprises the following steps: step 1, treating seeds step by step, wherein after the seeds are taken, the mildewed seeds and seeds with diseases and insect pests are picked out and discarded, then the seeds are disinfected, then the seeds are soaked with warm water, subjected to water treatment with gibberellin, and stored in sand; 2, the nursery land is treated, wherein weeding, deep ploughing, fertilization, soil improvementand seedbed disinfection are conducted on the nursery land, and it is guaranteed that soil meets the sowing requirement; 3, sowing and seedling raising, wherein the treated seeds are uniformly spreadon the optimized seedbed, buried with sand, and covered with pine leaves. Before sowing, seed dormancy caused by seed coats, endogenous inhibitors, seed embryos and other factors can be broken throughwarm water treatment, medium-low-concentration gibberellin water treatment and sand storage treatment on seeds, especially when the seeds are stored in sand until the seeds crack and radicles grow out, sowing is conducted, epicotyl dormancy breaking is facilitated, and the seed dormancy period can be shortened. More importantly, orderly emergence of the seeds is facilitated, and the emergence rate of the seeds is high. The method is easy to operate and high in operability in fields.
Description
technical field [0001] The invention relates to the technical field of seedling cultivation, in particular to a method for seedling cultivation of peony 'Fengdan' for oil. Background technique [0002] Fengdan peony (referred to as Fengdan for short), as the raw material for the production of traditional Chinese medicine paeonol, its root bark has medicinal functions such as analgesic, antipyretic, anti-allergic, anti-inflammatory, and immune. Fengdan contains paeoniflorin, paeonol, paeonol, paeonol, paeonol polysaccharides and other chemical components, among which paeonol is not only used as the main index to test the quality of paeonol, but also can be processed into paeonol for making Drugs against cardiovascular diseases can also be used as additives in daily chemical products such as toothpaste, toilet soap, toilet water, etc., and have great market potential in food preservation, health care, etc. Fengdan also has strong seed-setting ability, resistance to barrenness...
