[0004] Chinese patent document: A method for cultivating Gexianmi, application number: 99120005.5, the invention is a method for cultivating Gexianmi, the disclosed method includes culture solution preparation, algal seed preparation, bioreactor cultivation, and preparation of inoculum , cultivation, real-time monitoring, screening and harvesting, improvement of mechanical strength and drying. The cultivation is carried out in a bioreactor, which requires high labor and energy consumption, and produces a large amount of sewage at the same time, resulting in high production costs.
Chinese patent document: A method for cultivating Gexianmi with a bioreactor, application number: 200310111215.2, the invention is a method for cultivating Gexianmi with a bioreactor, the disclosed method includes culture solution preparation, algae preparation, Bioreactor cultivation, preparation of inoculum, cultivation, monitoring, harvesting, improving the mechanical strength of kudzu spheroids, drying, the cultivation is also carried out in a bioreactor, the construction cost is high, and the production cost is also high
This invention is a method for restoring the growth of wild resources in the paddy fields of Hefeng County, the original place of Gexianmi. The applicable range of rice fields is small, the growing season of Gexianmi is short, the yield is low, and the management is also cumbersome.
To sum up, it can be seen that the existing technology of artificially cultivating Gexianmi has defects such as high production cost and product quality that need to be improved; while the application range of field multiplication technology is small, the growing season is short, and it is difficult to meet the needs of large-scale cultivation of Gexianmi.

Embodiment 1

[0026] In the present embodiment, the method for cultivating Ge Xianmi in farmland specifically comprises the following steps:

[0027] (1) Preparatory work:

[0028] Including farmland selection, sorting and algal seed preparation, among which,

[0029] The selection and arrangement of farmland are specifically as follows: choose cinnamon soil farmland, yellow-brown soil farmland or paddy soil farmland with convenient drainage and irrigation as the cultivation field, wherein paddy soil farmland is the best. In this embodiment, paddy soil farmland is selected, and the area of ​​a single farmland is Can be big or small. After the crops are harvested in autumn and winter, usually from October to November, remove the crop stalks and weeds on the surface, so as to prevent the crop stalks and weeds from floating on the water surface after the irrigation of the farmland, blocking the sunlight and affecting the growth of Ge Xianmi. The removal of the crop stalks and weeds on the su...

Embodiment 2

[0041] In the present embodiment, the method for cultivating Ge Xianmi in farmland specifically comprises the following steps:

[0042] (1) Preparatory work:

[0043] Including farmland selection, sorting and algal seed preparation, among which,

[0044] The selection and arrangement of the farmland are specifically as follows: choose cinnamon soil farmland, yellow-brown soil farmland or paddy soil farmland with convenient drainage and irrigation as the cultivation field, wherein paddy soil farmland is the best. In this embodiment, cinnamon soil farmland is selected, and the area of ​​a single farmland is Can be big or small. After the crops are harvested in autumn and winter, usually from October to November, the crop stalks and weeds on the ground surface are cleaned up to prevent the crop stalks and weeds from floating on the water surface after the irrigation of the farmland, blocking the sunlight and affecting the growth of Ge Xianmi. After completing the above steps, w...

Abstract

The invention provides a method for cultivating common nostoc by using a farmland. The method comprises the following steps: selecting and arranging the farmland, preparing algae, and doing preparatory work; watering and leveling in a cultivated field to seed after a week; adjusting the pH value of water in the cultivated filed before seeding; spreading the algae into the cultivated field when seeding, and exposing on the surface soil in the cultivated field; keeping the depth of the water in the cultivated field at 2-16cm, so that a common nostoc group is completely submerged below the water level; keeping the soil layer and the water layer stable in the cultivated field; adding magnesium chloride, calcium chloride and dipotassium phosphate to the cultivated field every 15-30 days; harvesting the common nostoc group after cultivation is ended. The method for cultivating the common nostoc by using the farmland provided by the invention is simple and feasible to operate, and low in cost, the free farmland is fully utilized in winter, the produced common nostoc product is good in quality, the method can be widely applicable to the requirements of large-scale production of the common nostoc, and the income of local farmers is also increased.

Description

technical field [0001] The invention provides a method for cultivating Gexianmi, in particular to a method for cultivating in farmland, and belongs to the fields of biotechnology and applied phycology. Background technique [0002] Nostocsphaeroids (Nostocsphaeroids pseudosphaeroides), commonly known as field fungus, angelica, loosestrife, scientific name Nostocsphaeroids, is a rare freshwater economic cyanobacteria that mainly grows in the rice fields of Hefeng County, Hubei Province, harvested in spring; mainly is spherical. It is said that 1600 years ago, Ge Hong, a Taoist theorist, medical scientist, and alchemist in the Eastern Jin Dynasty, used Ge Xianmi to cure the stubborn illness of the crown prince of the dynasty. A delicacy for the royal palace and palace. Gexianmi is a famous specialty in Hefeng County, Hubei Province. It is a traditional food and has good medicinal and health effects. Its medicinal value is recorded in "Compendium of Materia Medica" and "Natio...
