Oil peony cutting seedling growing method

Abstract

The invention discloses an oil peony cutting seedling growing method and relates to the technical field of peony plantation. The method comprises the following steps: establishing a seedbed, i.e., selecting a plane place to establish the seedbed, laying straw chips with a thickness of 13-16cm at the bottom layer of the seedbed, burned soil with a thickness of 8-11cm at the middle layer and fine river sand with a thickness of 13-16cm at the upper layer, and performing sprinkling disinfection on the seedbed by use of a potassium permanganate liquid with a concentration of 0.2% before cutting; performing cutting acquisition and processing; performing cutting and seedbed management, i.e., vertically inserting cut stems into a matrix by a depth of 5-8cm with only terminal buds being exposed at a distance of 5*5cm, and immediately performing watering after insertion, wherein watering has to be frequently performed afterwards so that soil wettability can be maintained; performing anticorrosion processing, i.e., spraying a 800-time carbendazim solution once every seven days from the day of cutting, performing spraying two to three times together, and spraying ammonium biphosphate with a concentration of 3% on leaves after ten days of the cutting so as to facilitate growth of new roots; and performing transplanting. The management is standard, the cutting seedling growing survival rate is high, and the rooting growth speed is fast.

Description

Technical field: [0001] The invention relates to the technical field of peony planting, in particular to a method for raising seedlings by cuttings of peony for oil. Background technique: [0002] The use of tree peony refers to the species in the peony group of the genus Paeoniae, which are easy to bear fruit and have high seed oil content (especially high unsaturated fatty acid content 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. At present, the production of peonies cultivated in my country is usually based on seeding and propagation methods. The existing seeding and seedling management is not standardized, the germination rate and survival rate of seeding seedlings are low, the rooting speed is slow, and the time span required for planting is long.
