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 20-40 cm deep, and expose it to the sun for 20-30 days to sterilize naturally; then plow and rake it regularly several times , 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; afte...

Abstract

The invention relates to a planting method for releasing the dormancy of the 'Feng Dan' peony in a natural state, and belongs to the field of planting peonies for oil. The planting method includes the following steps: (1) land selection, (2) seedbed preparation, (3) seed collection, selection, disinfection, (4) 'Fengdan' seed pretreatment, (5) sowing treatment and other steps , Sowing 'Fengdan' peony in the natural state, from land selection, seed treatment to sowing, are strictly to ensure that the ecological environment is not affected, do not change the soil, and ensure the survival rate and germination rate of 'Fengdan' peony. This technology can not only increase the seedling rate of 'Fengdan' in the natural state, but also change the current situation of low germination rate of 'Fengdan' in production, and accelerate the development of industrialized production of 'Fengdan'.

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...
