Problems solved by technology

The growth of green algae affects the attachment of monospores, thereby affecting the amount of monospore shoots and the yield of Porphyra
The harvested laver requires a lot of manpower to remove the mixed green algae. With the rise of domestic labor prices in recent years, the removal of green algae has greatly increased the cost of laver processing.
According to the grade standard of dried laver in the laver trading market, special-grade vegetables are required to be completely free of green algae. With the increase of green algae, the grade will drop, which will directly affect the price of processed laver products.
Therefore, a large amount of growth of green algae has seriously affected the yield and quality of laver, and therefore greatly affected the economic value of laver and the development of laver industry

Embodiment Construction

[0045] The present invention will be further described below in conjunction with accompanying drawing of description and embodiment:

[0046] A method for preventing and controlling green algae epiphytes on laver cultivation rafts, combining Figure 23 Shown, comprise the following steps when making described laver cultivation raft:

[0047] According to the water depth and range of seaweed cultivation waters, select the corresponding fixed base (not shown in the figure), prong cable 11, empty rope 12, floating rope 13, net curtain 2, longitudinal pillar 1, rope, some moso bamboo floating frames 3 ; smear anti-green algae epiphytic paint on the moso bamboo floating frame and dry it; in the seaweed cultivation waters, the fixed bases are relatively fixedly connected to the bottom of the water in groups of two, and the prongs are connected to the fixed bases and pulled. The opposite empty ropes of the fixed base are dragged on the two ends of a pair of parallel floating ropes, ...

Abstract

The invention provides a method for preventing and controlling green alga overgrowth on porphyra cultivation raft frames and relates to the application of coatings such as water tank paint on the prevention and control over green alga overgrowth on the porphyra cultivation raft frames. The method comprises the steps that green alga overgrowth prevention paint is smeared on the porphyra cultivation raft frames, and the green alga overgrowth prevention paint is finishing paint, shipbottom paint, the water tank paint and the like. The method for preventing and controlling the green alga overgrowth on the porphyra cultivation raft frames can be used for preventing and controlling the green alga overgrowth on the cultivation raft frames in the cultivation industries of porphyra yezoensis and porphyra haitanensis.

Description

technical field [0001] The invention relates to a laver cultivation technology, in particular to a technology for preventing and controlling green algae growth on rafts for laver cultivation. Background technique [0002] Laver ( Pyropia ) belongs to the class Rhodophyta (Rhodophyceae), subclass Bangiophycidae, order Bangiales, and family Bangiaceae. Porphyra variegata grows naturally in the northern part of the East China Sea, the Yellow Sea and the Bohai Sea north of the Zhoushan Islands in Zhejiang Province. It is one of the most important artificially cultivated seaweeds in the world. It is the main species of Porphyra artificially cultivated in the north of the Yangtze River in my country. It is cultivated in other provinces, and Jiangsu is the main cultivation area of ​​Porphyra zebra. [0003] Porphyra zebra cultivation is the industry with the most economic value in the artificial cultivation of seaweed, and it currently has an industry scale of more than 2 billion ...
