Problems solved by technology

In traditional seedling cultivation, 'Fengdan' is mainly propagated by seeds, but there are segregation variations in the sown offspring, and the excellent traits of the female parent cannot be well preserved, and the seed germination time is long in the natural state, and the survival rate is low
Because 'Fengdan' seeds have typical secondary dormancy and physiological post-ripening phenomena, fresh mature seeds need to be post-ripened for a period of time, and the hypocotyl dormancy is released before they can germinate and take root. After rooting, the epicotyl dormancy needs to be released to grow into adult Seedlings, the sowing and seedling cycle is longer
Moreover, there are continuous cropping obstacles in the planting of the 'Fengdan' peony, and repeated cropping is not possible, which seriously affects the seedling growth rate of the 'Fengdan' peony in production.

Embodiment 1

[0081] A planting method for releasing dormancy of 'Fengdan' peony in a natural state, characterized in that: its specific operation steps are:

[0082] Step 1. Choose a cultivation site with flat surface, sufficient sunlight, loose soil, good ventilation and drainage, and the soil type is cinnamon soil; the effective soil depth is 100 cm; the gravel content is about 10%;

[0083] Step 2: Cut off all the vegetation on the surface of the sowing ground, spread it on the spot and burn it; after removing the vegetation, plow the land about 20-40cm deep, and expose it to the sun for 20-30 days to sterilize naturally; To achieve the effect of soft soil powder, no weeds and flat ground without large clods; before planting, every 1 m 2 Sprinkle 20-30 g of 3% carbofuran granules into the soil and 10-15 kg of 50% carbendazim powder in a ratio of 1:1000, and then evenly pour it into the soil to avoid volatilization of the drug effect; after the land is ready, press It is advisable to op...

Abstract

The invention relates to a planting method for relieving dormancy of 'paeonia ostii' in a natural state, and belongs to the field of paeonia suffruticosa andr planting. The planting method comprises the following steps of (1) land selection, (2) seedbed preparation, (3) seed harvesting, selection and disinfection, (4) 'paeonia ostii' seed pretreatment, (5) seeding treatment and the like. In the natural state, the 'paeonia ostii' is seeded, land selection, seed treatment and seeding are all strictly conducted to not affect the ecological environment, not change soil and ensure the survival rateand germination rate of the 'paeonia ostii'. The technology not only can increase the seedling rate of the 'paeonia ostii' seeds, but also can change the current situation of low germination rate ofthe 'paeonia ostii' seeding during the production, and accordingly accelerates the development of industrial production of the 'paeonia ostii'.

Description

technical field [0001] The invention belongs to the technical field of peony planting for oil, and in particular relates to a planting method for releasing the dormancy of the 'Fengdan' peony in a natural state. Background technique [0002] In 2011, the National Health Supervision Bureau approved peony for oil as a new type of woody grain and oil plant resource, and peony seed oil has become an important edible oil in my country. At present, my country's oil peony cultivars are mainly 'Fengdan' ( Paeonia ostii ) mainly. In traditional seedling cultivation, 'Fengdan' is mainly propagated by seeds, but there are segregation variations in the sown offspring, and the excellent traits of the female parent cannot be well preserved, and the germination time of seeds in the natural state is long and the survival rate is low. Because 'Fengdan' seeds have typical secondary dormancy and physiological post-ripening phenomena, fresh mature seeds need to be post-ripened for a period of...
