Embodiment Construction

[0005] The cultivation method of side calendula is described further now:

[0006] Lateral marigold can be cultivated in two ways: field direct seeding or seedling transplanting. Before sowing, the seeds do not need to be treated with any medicine, as long as they are full. Choose loose, fertile, well-drained, PH = (7-8), sandy loam soil with organic matter content greater than 2%. The selected land requires low nitrogen, high phosphorus, high potassium, and high calcium. The base fertilizer should be combined with compound fertilizer or potassium sulfate fertilizer and diammonium phosphate according to the soil test results, and more fully decomposed organic fertilizer should be applied. Sexually apply enough base fertilizer. In order to control underground pests, apply 3% Leer granule (1.5-1.7) kg per mu. Spread the fertilizer and medicine evenly, and then plow and harrow to level it out. During the 30-day germination period, the night surface temperature is (6-15) ℃, and...

Abstract

The present invention discloses a cultivation method of adonis amurensis, and is characterized by that its cultivation soil is a sandy loam whose pH value is 7-8 and organic matter content is greaterthan 2%, and its cultivation mode can adopt directly-sowing in field or cultivating seedling and transplantation. The Adonis amurensis cultured by said invention contains high astaxanthin content.

Description

1. Technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for cultivating lateral marigolds. 2. Background technology [0002] Astaxanthin can be extracted from calendula officinalis. Astaxanthin is an animal feed additive that is also used to color human food. Astaxanthin is mainly found in the bright red flowers of Marigold aeruginosa, but the number of petals of the current species of Marigold aeruginosa is small, compared with the number of plants, the content of astaxanthin is too low, so it is not suitable for large-scale planting. Shrimp The cost of obtaining green pigment is high. 3. Contents of the invention [0003] The inventor has obtained a new species of Marigold arvensis through long-term research and experimentation. The cultivated Aeruginosa aeruginosa has many petals and high content of astaxanthin, which is suitable for extensive promotion and purification in commerce. The purpose of the pres...
