Problems solved by technology

The leaves of peonies for oil cultivated by the prior art will fall off after oversumming, and the peony garden will be covered with dead branches and lack the vitality of green leaves, which will seriously affect the ornamental effect of the peony garden; and the early deciduous stage will cause less nutrient accumulation, insufficient branches, and flower bud differentiation. Few, weak tree vigor, easy to cause secondary flowering, directly affect the output of the next year

Abstract

The invention relates to an oil peony cultivation technique, in particular to a method for delaying oil peony leaf falling. The method mainly comprises the steps that a bactericide and cytokinin combined reagent is sprayed in the five phases including a phase before oil peony planting, a leaf expansion phase, a flowering phase, a fruit nature phase and a phase after fruit harvesting respectively, wherein the bactericide is one or more of carbendazim and chlorothalonil, and the cytokinin is one or two of KT and 6-BA. By the adoption of the method, the leaf retaining period of oil peonies can be prolonged by 15-20 days, and prolonging of an ornamental period of the oil peonies and increase of the oil peony yield in a next year are promoted.

Description

technical field [0001] The invention relates to the propagation and cultivation technology of peony for oil, in particular to a method for delaying the defoliation of peony for oil. Background technique [0002] 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 resistant, suitable for afforestation and forest planting on barren hills; planted for one year and harvested for a hundred years, low cost). [0003] Peony for oil can not only be used as an oil crop, but also has great ornamental value. The leaves of peonies for oil cultivated by the prior art will fall off after oversumming, and the peony garden will be covered with dead branches and lack t...
