Problems solved by technology

The rhizoid roots of the epiphytic algae go deep into the epidermal cells of the inner layer of the seaweed, and even a strong water flow cannot wash it off, and the outer skin of the host is cleaned with a brush, and some epiphytic algae remain inside the algae. The residual epiphytic algae will grow and continue to cover the surface of sea vegetables, so it is extremely difficult to completely clean up the epiphytic algae

Embodiment 1

[0019] The method for removing epiphytic algae of the present invention is:

[0020] (1) Take different types of herbicide pesticides, including paraquat, acetochlor, benzalkonium chloride, 2,4-D, Nongsita, alachlor, butachlor, acetaminophen, clomazone Pine, oxadiazon, atrazine, simazine, mesotrione, promethazine, propanil, trifluralin, glufosinate, bialaphos, bialaphos sodium, glyphosate, grass Glyphosate ammonium salt or glyphosate isopropylamine salt, etc., to carry out toxicity and weeding effect experiments.

[0021] On the basis of continuous experiments, we will eliminate most of the pesticides that are highly toxic and easily cause skin rot or eye skin irritation. At the same time, we will eliminate some herbicides with low solubility and great damage to Eucheuma. The herbicides that are not suitable for use include: Baicao Citrate, acetochlor, benzalkonium, 2,4-D, Nongsita, alachlor, butachlor, albadan, clomazone, oxadiazone, atrazine, simazine , Trimethoprim, Promatogin...

Embodiment 2

[0027] In mid-November 2009, 100 liters of algae killing agents with a concentration of 3g / l were prepared with seawater. The algae killing agents were plant herbicides glufosinate, bialaphos, bialaphos sodium, and glyphosate , Glyphosate ammonium salt or glyphosate isopropylamine salt, placed in a 200-liter square plastic bucket for later use.

[0028] Take about 250 kilograms of the green long-hearted Kappa that is seriously infected by epiphytic algae cultivated in Li'an Bay (see Figure 2A ), after preliminary cleaning of the surface dirt of sea vegetables with seawater, the sea vegetables are packed in net bags with a diameter of 40cm and a mesh size of 3cm×3cm. The sea vegetables in the net bags should be as loose as possible. Each net bag contains about 10 kg of sea vegetables. After finishing, put the mesh bags into the prepared preparations in turn, put 2 mesh bags each time, take out the mesh bags after 10 minutes, and put them in another square plastic bucket with a vol...

Abstract

The invention belongs to the technical field of marine organisms, and relates to a preparation for removing epiphytic algae from an alga body and an application thereof. The preparation for removing adherent unwanted algae from an alga body is a plant herbicide. The preparation for removing adherent unwanted algae from an alga body is mixed with seawater, and then the alga body is immersed in seawater to remove adherent unwanted algae, wherein 1-5 g of preparations are added into 1 liter of seawater, and the immersion time is 5-10 minutes. The preparation for inhibiting epiphytic algae of theinvention is a plant herbicide; the action mechanism is that primary reactions of photosynthesis of epiphytic unwanted algae is inhibited, and PSII and the shikimic acid cycle at the photosynthetic reaction center, which prevent metabolic disorder due to drug absorption of glue-producing algae, are mainly inhibited; the preparation of the invention has strong specificity, is economical and effective, has simple operation; epiphytic unwanted algae on the alga body are observed to be withered, shrunk, dry and dead within several days; the purposes of inhibiting epiphytic unwanted algae and keeping glue-producing algae alive are reached; and the contaminated glue-producing algae are recovered to have smooth surfaces and can grow healthily again.

Description

Technical field [0001] The invention belongs to the technical field of marine biology and relates to a preparation for removing epiphytic algae from algae and its application. Background technique [0002] A large number of red algae (mainly plants of the genus Viburnum, Kappa genus and Eucheuma genus) are naturally growing and distributed in tropical seas. They are the main biological resources for the production of different types of carrageenan in the world today. At present, only a small part of these red algae raw materials come from sea vegetables in tropical marine natural habitats such as coral reefs, and most of them come from artificially cultivated sea vegetables. In addition to my country’s Hainan, currently the Philippines, Indonesia, Malaysia, Vietnam and other Southeast Asian countries and Fiji and other Pacific islands, as well as Mexico and Brazil in Central and South America, and Africa’s Kenya, Tanzania and other tropical countries and regions have achieved the...
