Abstract

The invention discloses a breeding method for promoting drought resistance of peony and belongs to the technical field of agricultural planting. According to the invention, the drought-resisting breeding for the peony is realized according to the three steps: 1) ageing treatment, 2) mixing a drought-resisting agent with seeds, and 3) planting. According to the invention, the ageing treatment is combined with the drought-resisting agent, so that the germination rate of the seeds is effectively increased, the drought resistance of the seeds is promoted, and the mu yield of the peony is increased. According to the invention, the average mu yield of the peony is 238-246kg and is 16.7-20.6% higher than the mu yield 204kg of the conventional planting, the emergence rate of the seeds is 94-98%, the germination rate is 95.4-97.9%, the survival rate of the seedlings is 92.8-96.4%, the emerging time is 26-31 days, the determined organic selenium content of the peony seeds reaches up to 0.32-0.37mg / kg, and the economical benefit is remarkable.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a breeding method for improving drought resistance of peony for oil. Background technique [0002] Peony for oil is a shrub plant. Wild peonies are mainly distributed in Gansu Province, Sichuan Province, and northern Yunnan, mainly purple-spotted peonies, and Fengdan peonies in Shaanxi Province, Heze, Luoyang and other places. Currently, there are only two varieties of peony for oil used in production, Fengdan and Ziban, and Ziban is divided into grafted and seeded varieties. Peony for oil is a new kind of woody oil crop, which has the outstanding characteristics of "three highs and one low": high output (the yield per mu can reach 300 kg in five years, and the comprehensive benefit per mu can reach 10,000 yuan), high oil content (seed oil content 22%), high quality (unsaturated fatty acid content 92%), low cost (peony for oil is drought and barren res...
