Embodiment 1

[0030] The cultivation method of improving the biomass of Rhodiola angustifolia of the present embodiment may further comprise the steps:

[0031] (1) Water treatment: Put the transplanted Rhodiola angustifolia seedlings in a glass shed. After the Rhodiola rosea seedlings grow normally, water them until the soil moisture content is 50%, and then dry them naturally. Measure the soil content every day. Water quantity, when the soil moisture content is ≤15%, add water until the soil moisture content is 50%;

[0032] (2) Lighting treatment: After the Rhodiola angustifolia seedlings cultivated in the field start to grow normally, use a shading net for shading treatment, keep the shading rate at 0%, and measure the light intensity;

[0033] (3) Fertilization treatment: In the Hongyuan soil, add the above-mentioned quartz sand with a weight percentage of 10% of the Hongyuan soil to obtain the mixed soil, and transplant the Rhodiola angustifolia seedlings into the above mixed soil, an...

Embodiment 3

[0040] The cultivation method of improving the biomass of Rhodiola angustifolia of the present embodiment may further comprise the steps:

[0041] (1) Water treatment: Put the transplanted Rhodiola angustifolia seedlings in a glass shed. After the Rhodiola rosea seedlings grow normally, water them until the soil moisture content is 70%, and then dry them naturally. Measure the soil content every day. Water quantity, when the soil moisture content is ≤15%, add water until the soil moisture content is 70%;

[0042] (2) Lighting treatment: After the Rhodiola angustifolia seedlings cultivated in the field start to grow normally, use a shading net for shading treatment, keep the shading rate at 10%, and measure the light intensity;

[0043] (3) Fertilization treatment: In the Hongyuan soil, add the above-mentioned quartz sand with a weight percentage of 15% of the Hongyuan soil to obtain the mixed soil, and transplant the Rhodiola angustifolia seedlings into the above mixed soil, a...

Abstract

The invention discloses a cultivation method for improving the biomass of rhodiola kirilowii and belongs to the technical field of rhodiola cultivation. The cultivation method comprises the following steps of (1) moisture treatment, (2) light treatment and (3) fertilization treatment. According to the cultivation method for improving the biomass of the rhodiola kirilowii, the biomass of the rhodiola kirilowii can be effectively improved; the biomass of the rhodiola kirilowii is improved by 38.39% under moisture treatment; the biomass of the rhodiola kirilowii is improved by 23.75% under light treatment; and the biomasses of the rhodiola kirilowii to which nitrogen fertilizers, phosphorus fertilizers and potassium fertilizers are applied are improved by 159.76%, 136.59% and 248.78% correspondingly.

Description

technical field [0001] The invention relates to a cultivation method for increasing the biomass of rhodiola angustifolia, belonging to the technical field of rhodiola cultivation. Background technique [0002] Rhodiola kirilowii (Regel) Maxim is a perennial herbaceous plant of Crassulaceae, which is a precious Tibetan medicine. It grows on the plateau at an altitude of 3000-4500 meters. It mainly contains salidroside, tyrosol, and β-sitosterol. Anti-hypoxia, anti-aging and other effects, due to the many effects of Rhodiola plants, Rhodiola rosea medicines and health products are very popular, making the wild resources of Rhodiola rosea very scarce. In order to protect the wild resources of Rhodiola and avoid the impact of over-harvesting on the ecological environment, it is necessary to carry out research on the artificial cultivation of Rhodiola. [0003] Water, light and fertilization are indispensable control factors in the artificial cultivation process of plants, which...
