The growth environment and local conditions of kelp

Kelp Growth Environment and Conditions

Kelp generally grows on rocks on the seabed in the subtidal zone. It can also be artificially cultivated on ropes or bamboo. It is mostly distributed in the Northern Hemisphere, with a small amount distributed in the Southern Hemisphere. It is a species endemic to the North Pacific, with a small amount distributed in the Atlantic. Its growth is affected by temperature, light, nutrients and plant hormones.

Kelp Growing Conditions

1. The seabed where kelp grows should be flat, preferably a mud bottom or a muddy and sandy bottom, with a harder sandy bottom being second best, and the worst being a soft mud bottom, or a rocky reef bottom.

2. If kelp is artificially maintained, the water depth should be determined according to the cultivation form and the length of the seedling rope. It generally grows in sea areas above 5 meters during winter high tides. The breeding areas with strong currents and small waves are better. As long as a certain safety guarantee is provided, sea areas with deep water, strong currents and big waves are also suitable as breeding areas. The growth will be better in sea areas with cold water masses and upwellings.

Kelp growth temperature

Kelp is suitable for growing at temperatures between 1-13 degrees. The optimum temperature for kelp spore development is between 15-20 degrees, and preferably between 5-10 degrees. The growth of male and female gametophytes is fastest at 15 degrees and slowest at 5 degrees.

Kelp growth process

my country's kelp generally grows naturally in the Bohai Sea and other sea areas. Due to the different latitudes of the sea areas, the maturity period of kelp is also different. However, it is generally harvested from May to July.

Kelp planting time and method

When planting kelp, seedlings are produced through spore germination, but spore germination has very high requirements for seawater temperature. However, if the seawater temperature is artificially controlled, it is also very easy to cultivate. The kelp spores can germinate into seedlings in the nursery room. The kelp seedlings are clamped into the seams of the hemp rope, and the hemp rope is tied to the floating raft of the farm. After cultivation, it becomes a kelp field.
