A kind of floating raft hanging net type planting method of Qiongzhi

Abstract

The invention discloses a buoyant raft hanging net type gelatinae planting method. The buoyant raft hanging net type gelatinae planting method comprises the following steps that S1, a planting regionis selected, wherein an offshore sea region of the South China Sea area is selected, the salinity is required to 25-40%., the water depth at a high tide level is 3-7 m, and the water depth at a low tide level is not smaller than 1 m; S2, a buoyant raft hanging net planting device is erected; S3, planting is performed, wherein it is required for offspring seeds that miscellaneous algae with bodiesfree of attached epiphytes and other living creatures are adopted and color is red or red brown, algae blocks of 10-20 cm<2> are torn from the algae bodies during seedling separation, and the weight does not exceed 100 g; S4, final-period management is performed, the firmness and attachment situation of seedlings are checked every day within one week after the seedlings are planted, and timely seedling supplementation and adjustment are performed when dead seedlings or nonuniform seedling distribution is found. The buoyant raft hanging net type gelatinae planting method has the advantages thatthe method is simple and easy to operate, low in cost and high in yield, the dependency on a growth area is small, the problem is effectively solved that gelatinae planting is limited due to dispersecoral reef distribution, resource lack and other causes in our country, and the method can be popularized and applied in a large-scale way.

Description

technical field [0001] The invention belongs to the field of mariculture, and in particular relates to a floating raft-hanging net-type planting method of Qiongzhi. Background technique [0002] Qiongzhi (E. gelatinae, commonly known as "Qiongzhi Eucheuma") is a kind of marine algae plant, belonging to Rhodophyta, Red Lemonaceae, "shade-loving plants", the suitable water temperature is 20-35 ° C, the general condition The lower attachment grows on coral reefs, and is mainly distributed in the coastal areas of Hainan Island, the West and Dongsha Islands, and the Penghu Islands in Taiwan. [0003] Qiongzhi is a tropical and subtropical macroalgae with high economic value. It is rich in polysaccharides and is one of the important raw materials for the carrageenan industry. In addition to being the main raw material for extracting carrageenan from Qiongzhi, the algae body can be used as food, and the whole algae can be used as medicine after drying. Qiongzhi plays an extremely...
