An outdoor roller-type method for collecting seedlings of Porphyra zebra spores

Abstract

The invention discloses an outdoor roller type porphyra yezoensis conchospore seedling collecting method. In the conchospore seedling collecting season, the water temperature of a porphyra yezoensis seedling growing chamber is controlled to be higher than 24 DEG C, and the indoor light is controlled to be smaller than 200 lux. Conchospore collection can be carried out when the seawater temperature is controlled to be 19+ / -1 DEG C, the outdoor temperature is controlled to be 23+ / -0.5 DEG C and the seedling collecting light strength is higher than 3000 LUX. Flowing of seedling collecting water is controlled through a seedling collecting waterwheel, and the porphyra yezoensis conchospore seedling collecting way is automatized. The conchospore spreading and attachment rate is improved, conchospore waste is reduced, a net curtain can collect seedlings evenly and can enter sea in time, the labor cost is reduced, and the porphyra yezoensis seedling growing cost is lowered.

Description

technical field

[0001] The invention relates to a laver cultivation technology, in particular to an outdoor roller-type method for collecting conchospores of porphyra zebra zebra seedlings. Background technique

[0002] Porphyra is an important economically cultivated species among seaweeds, especially Porphyra variegata is the most beautiful one in Porphyra. Although the proportion of seaweed in the world's aquatic products is relatively small, and the scope of cultivation is not wide, it is popular with consumers for its delicious taste, high nutritional value, and easy portability. Among aquatic products, it is an important product for foreign exchange earning through export.

[0003] Seaweed is one of the most important artificially cultivated seaweeds in the world. It is a natural healthy food with a huge market. It accounts for 2 / 3 of the output value of artificially cultivated seaweed in the world. Japan has the highest production of seaweed, followed by South Kore...

Embodiment Construction

[0033] A kind of outdoor roller type Porphyra zebra spores picking seedling method:

[0034] During the conchospore collection season, control the water temperature in the laver nursery room above 24°C, and control the indoor light below 200lux. Every morning, check the shell filaments at each pond mouth. According to the inspection results, If the maturity of Porphyra zebra spores is not enough, it is necessary to stimulate the maturity of Porphyra zebra spores by means of water stimulation;

[0035] When the seawater temperature is 19±1°C, the outdoor temperature is 23±0.5°C, and when the light intensity for picking seedlings is above 3000LUX, conchospores can be collected;

[0036] Before collecting the ascospores of shell filaments, the preparations before collecting the ascospores must be done first. First, install and debug the collection device for collecting ascospores outdoors:

[0037] The collection device includes a water tank for picking seedlings, a water truck fo...
