A cultivation method for increasing the yield of paeonia ostii through close planting and fertilizing

Abstract

The invention provides a cultivation method for increasing the yield of paeonia ostii through close planting and fertilizing and belongs to the technical field of peony cultivation. The method comprises the steps of: in autumn of the first year, planting seedlings with three planting densities, wherein the seedlings are all subjected to stubbling treatment; in early spring of the second year, applying organic fertilizer; after blooming in spring of the third year, applying organic fertilizer and foliage fertilizer cooperatively; in summer of the third year, applying foliage fertilizer; in autumn of the third year, before winter, applying organic fertilizer. While paeonia suffruticosa for oil is planted, vegetables are interplanted. The method can promote peony branching; after a single-stem peony seedling is subjected to stubbling, 2-5 branches can be increased, so that the yield is increased; the types and the amount of applied organic fertilizer and the number of times of application of organic fertilizer are of great importance for the growth of paeonia ostii, and further the biotic stress resisting capability of plants can be influenced, and the yield can be influenced; through the interplanting of grain and oil crops, land resources are fully utilized.

Description

technical field [0001] The invention relates to a cultivation method for promoting the yield of Fengdan peony through dense planting and fertilization, and belongs to the technical field of peony cultivation. Background technique [0002] Peony is a unique tree species in my country, belonging to Paeoniaceae Paeoniae genus. Peony is a small perennial deciduous shrub. Wild peony grows slowly, has a small plant type, and the plant height is mostly between 0.5 and 2 meters. It takes 3-5 years for seed reproduction to bloom and set seeds. The root is fleshy, thick and long, the center is lignified, and the length is generally 0.5-0.8 meters. On March 22, 2011, according to the provisions of the "Food Safety Law", the Supervision Bureau of the Ministry of Health officially approved peony seed oil as a new resource food after review by the New Resource Food Review Expert Committee. Peony for oil includes two series of peony and purple spot peony; the root of Fengdan has been use...

Problems solved by technology

At present, in the existing technology, Fengdan is all seedlings for sowing and breeding seedlings. Many enterprises produce peony seeds by planting peony seedlings. Generally, the seedlings are dug out from the ground and planted directly. In order to quickly achieve the effect of flowering and setting seeds, no leveling Non-scientific methods such as stubble and large-scale application of compound fertilizers and other chemical fertilizers are used for cultivation, resulting in the phenomenon of single-stalk seedlings of Fengdan. The structure of fertilizer input is unreasonable, and qualitative and quantitative fertilization cannot be rationally applied; Ammonium, etc., the pollution of the environment caused by the application of chemical fertilizers is indeed the same, and it also affects the yield of peony and the quality of peony seeds

In addition, the background technology is simply planting peonies, which cannot make full use of land resources and increase production and income.
