Problems solved by technology

The lutein content of the pigmented marigold grown at an altitude of 1700-2200 meters is much higher than that of other provinces. There is still a lack of mature technology in the key link, resulting in the insufficient development and utilization of this important plant resource. Establish and improve the construction of pigment marigold seedling breeding bases and industrial production bases in high-altitude areas, and cultivate high-content, high-yield pigments. Marigold is the main way to realize the sustainable development of pigment marigold in high altitude areas, and it is also the inevitable choice to ensure the sustainable development of lutein industry

Embodiment 1

[0018] Embodiment 1: A kind of introduction and cultivation technique of pigment marigold in high-altitude areas includes the following processes: 1. sun-dry the seeds for 3-4 days before sowing, then soak the seeds in warm water at 35-40°C for 3-4 hours, Take it out, wash it with clean water, and dry it; ②By the middle of March to the end of March, carry out artificial seedling cultivation on the seedbed by sowing, the germination rate of the seeds will reach more than 90%, and the sowing rate will be 0.015-0.020 kg / mu; ③In the Before the end of April (when the stem reaches 10-15cm), transplant to an altitude of 1700-2200 meters, the soil pH value is 6-7, the temperature is 15-28 ℃, and the field is irrigated with sufficient light and water; suitable for dry land , The wasteland should be transplanted before mid-May.

Embodiment 2

[0019] Embodiment 2: A kind of introduction and cultivation technology of pigment marigold in high-altitude areas includes the following processes: 1. sun-dry the seeds for 3-4 days before sowing, then soak the seeds in warm water at 35-40°C for 3-4 hours, Take it out, wash it with clean water, and dry it in the air; ②By the middle of March, carry out artificial seedling cultivation on the floating tray by live broadcasting, the germination rate of the seeds can reach more than 95%, and the seeding rate is 0.010-0.013 kg / mu; ③At the end of April In the past, it was transplanted to an altitude of 1700-2200 meters, the soil pH value was 6-7, the temperature was 15-28°C, and the field was irrigated with sufficient sunlight; suitable dry land and wasteland should be transplanted before mid-May.

Embodiment 3

[0020] Embodiment 3: A kind of introduction and cultivation technique of pigment marigold in high-altitude areas includes the following processes: 1. sun-dry the seeds for 3-4 days before sowing, then soak the seeds in warm water at 20-25°C for 8-12 hours, Take it out, wash it with clean water, and dry it; ②By the end of March to mid-April, carry out artificial seedling cultivation on the seedbed by sowing, the germination rate of the seeds can reach more than 90%, and the sowing rate is 0.015-0.020 kg / mu; ③In the Transplant to an altitude of 1700-2200 meters before the end of April, the soil pH value is 6-7, the temperature is 15-28°C, and the field is irrigated with sufficient sunlight; suitable dry land and wasteland should be transplanted before mid-May. plant.

Abstract

The invention discloses an introduction and cultivation technique of pigment marigold in a high altitude area, in particular an introduction and cultivation technique for an area at an altitude between 1,700 and 2,200 meters. The method comprises the steps of pretreatment of seeds of pigment marigold, seedling raising, transplanting, management and harvesting. The method adopts physical and chemical method to pretreat the seeds to achieve a germination percentage of the seeds of 90 percent and a uniform seedling raising means to provide high quality seedlings for large scale planting. By planting pigment marigold in a high altitude area, the yield of fresh flowers and content of xanthophylls in the fresh flower are greatly improved. The cultivation method, compared with the prior method, contributes to construction of standard pigment marigold plantations, carrying out standard planting demonstration of pigment marigold and improving the technological content of the pigment marigold, enables farmers to learn planting technologies of pigment marigold as quickly as possible and obtain high quality pigment marigold products, and greatly improves economic benefits.

Description

technical field [0001] The invention relates to the introduction and cultivation technology of pigment marigold in areas with relatively high altitude (1700-2200 meters) Background technique [0002] Yunnan Province has unique natural advantages and is the province with the most plant resources in my country. The unique geographical and climatic conditions have bred a variety of plant resources. The special natural environment in the plateau area provides the most superior growth conditions for the growth of pigment marigolds. . The lutein content of the pigmented marigold grown at an altitude of 1700-2200 meters is much higher than that of other provinces. There is still a lack of mature technology in the key link, resulting in the insufficient development and utilization of this important plant resource. Establish and improve the construction of pigment marigold seedling breeding bases and industrial production bases in high-altitude areas, and cultivate high-content, high...
