Embodiment 1

[0016] (1) Preparation for 7 days before ascospore picking seedlings

[0017] In early and mid-September, the altar seaweed shell filaments mature in the later stage of cultivation. At this time, the water temperature in the nursery pond is above 28°C, and the light is around 500Lx. According to the determined time for picking seedlings of conchospores, the water temperature in the seedling pool was lowered to 28°C 7 days before seedling picking, and fresh seawater was replaced every day 3 days before seedling picking, and the water temperature in the seedling pool was lowered to 27°C, and water pumps were used to stimulate it during the day.

[0018] (2) Preparation 1 day before ascospore seedling picking

[0019] The morning of the day before the collection of conchospore seedlings starts, the water pump runs for 24 hours, and the temperature control facility (cooling water) is used to reduce the nursery pond to 25°C, and at night to 23-24°C.

[0020] (3) Ascospore seedling...

Abstract

The invention relates to an indoor conchospore seedling picking method for porphyra haitanensis shell conchocelis. The seedling picking method comprises the following steps: (1) preparing 7 days before conchospore seedling picking; (2) preparing 1 day before conchospore seedling picking; (3) carrying out conchospore seedling picking. The method accords with the biological property of porphyra haitanensis, can meet the productive conchospore seedling picking requirement of porphyra haitanensis, is a technical method for large-scale cultivation and centralized seedling providing of porphyra haitanensis, overcomes the defects that plentiful shells are irritated while being conveyed to a sea area and operation in a far sea area is failed, and has the advantages that conchospore seedling picking and large-scale seedling providing of porphyra haitanensis can fulfilled indoors, thereby providing convenience for cultivation and centralized seedling providing of porphyra haitanensis.

Description

technical field [0001] The invention belongs to the field of seedling cultivation, and in particular relates to a method for picking seedlings of conchospores indoors from shell filaments of algae laver. Background technique [0002] Porphyra is an important economically cultivated seaweed in my country, and Porphyra altar is a cultivated species in the south coast of my country. In the later stage of altar laver seedling cultivation, its filaments mature and have the biological characteristics of concentrated release of conchospores, and the altar laver cultivation sea area is a harbor sea area. Therefore, sea seedlings, especially sea spore-splashing water seedlings, are the most important choice in Fujian, my country. The unique method of harvesting seedlings adopted in Zhejiang Dengtan laver cultivation area. The operation of picking seedlings by splashing spores on the sea surface is simple. On the day before picking conchospores, hang the mature shell filaments into th...
