What is the value of eating laver?


Laver is a unique variety of laver in China. It is mainly widely cultivated in coastal areas such as Fujian Province and Zhejiang Province in China. As an important seaweed for aquaculture, 20g pure laver is not only of high economic value but also nutritious, with high protein and vitamin content and rich dietary fiber content.

Laver has been artificially cultured in seawater, but it is easy to suffer from diseases due to the weather, resulting in reduced or even no harvest. Mastering the law of weather change can effectively reduce and prevent diseases.

Temperature changes have a direct impact on the harvest of laver. For example, picking seedlings before the "White Dew" solar term, when the temperature is too high, the seedlings will fall off and rot, while picking seedlings after the "cold dew", when the temperature becomes low, the growth of laver seedlings will be slow, affecting the yield of laver.

In the breeding process of laver, we should closely monitor the precipitation, because the precipitation will directly affect the proportion of seawater and the content of nitrogen and phosphorus nutrients in the water. If the rainfall is high, it will reduce the proportion of seawater, and at the same time bring nutrients from the land to the sea, increasing the content of nutrients in the sea, and then laver will grow fast and well. If there is no rain for a long time, the content of nitrogen and phosphorus in seawater will be reduced, and the seaweed will suffer from "green change" due to the lack of nutrients.

The tidal range directly affects the drying time of the laver, and the drying time has a great influence on the growth of the laver. Short drying time, not only dialogue breeding fast, and bacteria easy to breed, especially laver rot easy to breed, the growth of pathogenic bacteria directly leads to the production of laver, therefore, artificial culture laver can maximize the use of the middle tide area. In the middle and late periods, the laver table can be appropriately moved to the middle high tide area for cultivation to extend the dry dew time.

In laver farming, we should pay close attention to the changes in solar terms and weather and make effective adjustments in time to avoid losses.
