A cultivation method for improving yield and quality of Cistanche deserticola

Abstract

The invention relates to a cultivation method for improving the yield and the quality of Cistanche deserticola. Annual Haloxylon ammodendron saplings are selected, and are planted in desertified loess in spring or autumn according to a planting density of 0.15-0.52 plant / m<2>, humus soil is applied according to a ratio of 1000-2000 g / plant, the planted samplings are timely watered to ensure the survival rate, inoculation with a Cistanche deserticola seed mixture is carried out after the Haloxylon ammodendro saplings grow to about 1.5 m, the humus soil is applied again according to a ratio of 500-2000 g / plant, the inoculation time is March to May Or October to December every year, the Cistanche deserticola seed mixture comprises Cistanche deserticola seeds subjected to seed soaking treatment in a seed soaking solution, sucrose, L-tyrosine, L-phenylalanine and mint powder, the seed soaking solution is a 3-5 mg / L fluridone solution, the seed soaking treatment time is 12-36 h, and the Cistanche deserticola seeds subjected to seed soaking treatment are obtained through drying the soaked seeds in the shade. The cultivation method has the following advantages: the inoculation process of the Cistanche deserticola seeds is simple, and can effectively promote the germination of the Cistanche deserticola seeds and effectively improve the yield of the Cistanche deserticola planted in the desertified loess; and the composition of the Cistanche deserticola seed mixture can be screened to obviously improve the content of effective components comprising echinacoside and verbascoside in the artificially planted Cistanche deserticola, improve the quality of the artificially planted Cistanche deserticola and effectively enhance the drug effects and the economic benefits of the artificially planted Cistanche deserticola.

Description

technical field [0001] The invention belongs to the field of horticulture, and in particular relates to a cultivation method for improving the yield and quality of Cistanche deserticola. Background technique [0002] Cistanche (Herba Cistanches), also known as Black Commander, Xinjiang Yun, Dayun, Cistanche, is a perennial parasitic tall herb of Orobanchaceae (Orobanchaceae) Cistanches (Cistanches), 40-160cm high, flowering May-June, fruiting period From June to August, it is a rare and precious medicinal material unique to desert areas such as Xinjiang, Inner Mongolia, Gansu, and Ningxia in my country, depending on the parasitic plants. There are mainly Cistanche deserticola (Cistanche deserticola Y.C.Ma), Cistanche salsa (Cistanche salsa (C.A.Mey.) G.Beck.) and Cistanche salsa (C.A.Mey.) G.Beck.). Cistanche deserticola is a well-known tonic Chinese medicine, which has the effects of nourishing kidney yang, nourishing essence and blood, moistening intestines and laxative, a...

Problems solved by technology

However, due to the parasitic characteristics of Cistanche deserticola, its natural reproductive capacity is very low, coupled with long-term large-scale and unreasonable excavation, the wild resources of Cistanche deserticola are on the verge of exhaustion, and it has also seriously damaged the ecological environment of deserts and desert areas, and the relationship with the global climate environment. Gradual deterioration together exacerbates desertification of the land

[0003] In order to alleviate the contradiction between supply and demand of Cistanche and improve the environment in desertification areas, extensive and effective experimental researches have been carried out on the artificial planting of Cistanche in China. Facing such as low inoculation efficiency, the output and quality of Cistanche are extremely unstable, which greatly affects the efficacy of Cistanche and the economic benefits of artificial planting of Cistanche, making the artificial planting of Cistanche face a dilemma similar to that of artificial planting of ginseng, which is not conducive to maintaining the quality of Cistanche. The efficacy of the medicine is also not conducive to promoting the governance of the environment in desertified areas, and it is not conducive to maintaining consumers' recognition of the artificial cultivation of Cistanche.

[0004] Aiming at the problem of unstable yield and quality of Cistanche artificially planted in the desert, the present invention intends to provide a cultivation method for improving the yield and quality of Cistanche artificially planted
