Embodiment 1

[0020] 1. Selection and arrangement of planting land: Select a plot in Jinji Town, Litong District, Wuzhong City, Ningxia, with a length of 30 meters, a width of 10 meters, an area of ​​300 square meters, sandy soil, good water permeability, flat land, and a slope of less than 5° . Before planting, rake and level the soil surface to remove large sand and gravel.

[0021] 2. Seed production: Spray an appropriate amount of water on the original plant of Nostococcus hairiformis to make the algae filament fully absorb water, straighten it naturally, cut it into short bundles of 5cm with scissors, arrange it into sheets, each piece weighs 5g, and let it dry in the air Dry.

[0022] 3. Sowing the Nostoc hairiform seed sheets that have been produced, and spread them evenly. The distance between the seed sheets is 30cm. There are 9 seed sheets per square meter, and a total of 15Kg is sown. Spray water while sowing to moisten the seed sheets. , attached to the soil.

Abstract

The invention relates to a method of culturing nostoc flagelliforme in a large scale. The method fully utilizes long sunshine duration, low air humidity, and other natural conditions in arid-semi-arid regions (natural distribution regions of the nostoc flagelliforme), reduces the culture cost and achieves large-scale culture. Seed plates having different sizes and different sowing distances are adopted, and the yield in unit area and culture time can be adjusted freely. After sowing, the seed plates of the nostoc flagelliforme are covered with screens, thus preventing seed plate displacement, breakage, crushing, and other loss caused by strong wind during a culture process, and preventing rain washing. A dry-wet rhythmic irrigation program and spraying of water and fertilizers are adopted, thus preventing autolysis of algal filaments in wet states for long time, and increasing the growth rate in unit area to the utmost. The method is suitable for large-scale culture of the nostoc flagelliforme.

Description

technical field [0001] The invention relates to a method for large-scale cultivation of Nostoc hairlike algae. technical background [0002] Nostoc flagelliforme (Berk. & Curtis) Bornet & Flah, a terrestrial cyanobacteria belonging to the genus Nostoc of the cyanobacteria Nostocaceae, it is dark brown in a dry state, and its shape is similar to hair, commonly known as Nostoc, Nostoc hairiformis is widely distributed in the world, mainly in arid-semi-arid deserts and grasslands. In my country, it is mainly distributed in Ningxia, Inner Mongolia, Gansu, Qinghai and Xinjiang. Hundreds of years ago, there were records of eating Nostoc hairiformis in our country. It is rich in nutrition and expensive. In addition, it has a homonym with "facai", so it is regarded as a rare delicacy and has become a traditional famous dish in my country and Southeast Asian countries. Along with the growing market demand, lead to the excessive collection of Nostoc hairiform, it is reported that ever...
