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 discloses a method for preventing and controlling the epiphysis of green algae on a laver cultivation raft, which relates to the application of coatings such as tank paint in preventing and controlling the epiphysis of green algae on a laver cultivation raft. The method of the invention is to smear the anti-green algae epigenetic varnish on the laver cultivation raft, and the anti-green algae epiphytic varnish used is top paint, boat bottom paint and water tank paint. The method of the invention can be used in the cultivation industry of Porphyra variegata and Laver algae to prevent and control the epiphysis of green algae on the cultivation raft.

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] Pyropia belongs to Rhodophyta, Rhodophyceae, Bangiophycidae, Bangiales, 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 US dollars worldwide. China is a major producer...
