Shidai Marine has a kelp farming base of 1000 hectares ,and employs thousands of people to cultivate and harvest kelp, more than 200,000 tons of kelp can be harvested every year.

What is Kelp

Laminaria japonica is of kelp genus, kelp family and Phaeophyta kingdom. It’s shaped like a long and flat Gametophytic blade, brown in color. Two longitudinal furrows run across the middle of the leaves, shaping a middle zone. Generally speaking, it is 2 to 6m long, 15 to 45cm wide, a nutritious large edible alga. Laminaria japonica is naturally dispersed in sea area with high altitude, a cold water alga, with the water temperature most suitable for growth being 0 to 13 ℃. It stops growing at over 20 ℃. Living 3 to 5m under water, laminaria japonica has rich nutritional value, containing active substance such as kelp polysaccharide, mannitol, betaine, and vitamin; mineral elements such as organic iodine, calcium, iron and zinc. It has wide application in industries such as agriculture, industry and food.

Characteristic Active Ingredients of Kelp

Linking Function of Kelp

As we all know, seawater is rich in nutrients, and the nutrients leached from the land are still flowing to the sea, and kelp is undoubtedly the beneficiary, it can absorb marine nutrients equivalent to 440,000 times itself, so kelp contains a full spectrum of mineral elements . Not only that, kelp itself is also rich in natural plant hormones, kelp-specific active substances and a variety of amino acids.

It is precisely because kelp fertilizer is rich in material components that it can help plants establish a strong and developed root system, and promote the absorption and utilization of soil nutrients, water and gas by plants; Transport of nutrients and photosynthetic products; can promote plant cell division, delay cell senescence, increase plant chlorophyll content, effectively improve photosynthesis efficiency, increase yield, improve quality, and enhance crop resistance to drought, cold, pests and other stress resistance functions It can also improve soil structure and enhance soil water retention capacity.
