How to grow sea grapes

The earliest producing area of sea grape is in Okinawa, Japan. It is a kind of edible algae growing in sea water. It has very high requirements on the growth environment and water quality. Artificial culture is not very simple. So far, only a small number of areas can be planted. China is one of them. Due to its low yield and rich nutrition, the market can buy 50 to 150 yuan a kilogram. In some places, you can even buy a few hundred yuan per jin, so let's learn how to cultivate grapes in the sea.

1. Site selection

As the life of sea grapes is in that habit and the requirements for all aspects are relatively high, so we will make careful consideration in the choice of breeding land, taking into account the problems of wetness and salinity, we generally give priority to the beach and the location near the coast, and secondly, we can also use the more advanced technology to breed in the coastal zone.

2. Planting

We all know that algae generally grow asexually, so we only need to purchase relatively robust, disease-free, full-grained, high-glossy sea grape plants. finally, the selected seedlings can be planted in the selected planting area.

3. Fertilization

When the sea grape is still in the seedling state, more nutrients are needed. This is because we mainly use organic fertilizer or high-efficiency fertilizer specifically for the growth of algae to fertilize. Generally, we need to apply fertilizer once a month. This can promote the rapid and efficient reproduction of sea grapes. After the sea grape algae grows tall and long, it can be carried out according to its specific fertilizer demand.

4. Temperature control

Sea grape is a tropical plant, although it is a plant living in water, but its ability to resist cold years is not very strong, so we must pay attention to adjust the temperature in the water body in the process of planting, so as not to affect the growth of sea grape. The most suitable temperature for the growth of sea grapes is generally about 22 to 32 degrees, of which the lowest temperature had better not exceed two degrees, otherwise it will freeze to death.

5. Disease prevention

Sea grape is a kind of plant that lives in sea water, and some insect pests and diseases caused by water pollution often occur in the process of its growth, so we should be prepared for prevention. in daily management, insects need to be killed every other month or so, which can enhance the resistance of sea grape plants.

6. Water quality

The water quality of sea grape culture is very important, it is related to the survival of sea grape, so we need to purify and filter the water body many times during culture and the whole process of culture. Clean up the microbes in the water as much as possible, so as to ensure the healthy growth of cultured sea grapes.

7. Lighting

The growth of sea grape needs sufficient light, so we should ensure that there should be light suitable for the growth of sea grape in the farm, so that the sea grape group can comprehensively carry out photosynthesis, and at the same time, it can also be carried out in the way of semi-shading, but the intensity of shading is not too great, so as to avoid lack of light, resulting in poor growth and development of sea grape and other problems.
