Seedling growing method for oil peonies

Abstract

The invention discloses a seedling growing method for oil peonies, and relates to the technical field of peony planting. The seedling growing method is characterized by including the following steps that the seeding time of oil peonies is selected to be from early September to early October; before seeding, seed selection is carried out with the water selecting method, seed soaking is carried out for 20 hours to 40 hours with mixed liquid of potassium pyrophosphate with the mass concentration of 1%-5% at the temperature of 40 DEG C to 50 DEG C and lithium diisopropylamide, the mass ratio of the potassium pyrophosphate to the lithium diisopropylamide is (3-4):1, and after seeds fully absorb water, swell and are disinfected, seeds can be used for seeding; seeding is carried out with the seeding method, the field water capacity is 65% to 75%, ditching and seeding are carried out on made high ridges, ditching is carried out according to the row spacing of 15 cm to 20 cm, the ditch depth is 8 cm to 12 cm, the width is 4 cm to 5 cm, seeds are evenly scattered into ditches, the intervals between seeds is 1 cm to 2 cm, and then 3-5-cm earthing is carried out; field management is carried out. The seedling growing method is good in sprouting effect, high in germination rate and survival rate, easy and convenient to operate and low in cost.

Description

Technical field: [0001] The invention relates to the technical field of peony planting, in particular to a method for raising seedlings of peony for oil. Background technique: [0002] Peony for oil refers to the kind that is easy to bear fruit in the peony group of the genus Paeoniae, and the seeds have high oil content (especially the content of unsaturated fatty acids such as α-linolenic acid), and are suitable for cultivation as oil crops. According to the 2013 No. 9 Announcement of the Ministry of Health of the People's Republic of China, the seed oils of Paeonia ostii and Paeonia rockii can be used as new resource food. The seedling raising method of existing almost medium oil peony is relatively simple, has following shortcoming, 1, the seed of oil peony is harder, only the effect of accelerating germination by soaking in common warm water mode of accelerating germination is relatively poor, causes germination rate to be lower; 2, common When raising seedlings, more ...

Problems solved by technology

The seedling raising method of existing almost medium oil peony is relatively simple, has following shortcoming, 1, the seed of oil peony is harder, only the effect of accelerating germination by soaking in common warm water mode of accelerating germination is relatively poor, causes germination rate to be lower; 2, common When raising seedlings, more fertilizers need to be applied, and the cost is high; 3. The peony seedlings that have just germinated do not like strong light, and are easy to wilt under strong sunlight, while the shade net method used for shading is relatively clumsy and expensive. not easy to operate
