Lin Zeng's plan this time is to use mangrove plants to refine a batch of special plants suitable for China's coastal waters.

Ordinary mangrove forests, usually grown in the tidal flat and shoal areas at the junction of land and sea. The distribution of mangrove forests increased with the decrease of latitude, the average daily temperature increased, and the growth situation gradually improved.

These mangrove plants are also known as marine fences and guardians of the sea in a high-salinity environment.

In many natural disasters brought by the sea over the years, the villages protected by mangroves are usually the best preserved and have the lowest loss of life. Whether it's a tsunami or a hurricane, there are mangrove areas that have protected the local population from the hardest attacks, and even in the areas where the wind and waves hit the hardest, they still remain safe.

Lin Zeng's choice of mangrove plants as the first giant plants to be refined by hand was carefully considered.

First of all, the refined giant mangrove plants can form a large area of natural plant archipelago in the coastal waters of China, which can not only provide a rich habitat for a large number of marine creatures and birds, but also become the first protection fence of the Chinese ocean.

These huge plant islands have a more stable structure than ordinary islands and reefs, and with other special plants, humans can live normally on the plant islands, carry out daily activities, establish military bases, small villages and towns, and have no problem at all.

The depth of the ocean in the coastal waters of China is not high.

The average depth of the Bohai Sea is 18 meters, and 95 percent of the area does not exceed 30 meters.

The average depth of the Yellow Sea is 44 meters, and the maximum depth is 140 meters north of Jeju Island.

The depth of the East China Sea is 70-200 meters.

The average water depth in the South China Sea is around 1,212 meters, and the sea depth on the offshore continental shelf is even shallower.

At present, the seeds of the mangrove flora refined by Lin Zeng can grow in the ocean at about two or three hundred meters, which is enough to form a large number of plant islands in the surrounding areas of China.

These plant islands can not only allow China's maritime power to expand externally and improve the utilization rate of offshore waters, but also slow down eutrophication of offshore seawater and protect the living space of marine life.

Lin Zeng planned to plant the first batch of mangrove island plants near the base of Mount Danube to provide a stable island base for the marine farmland near Mount Danube.

This is why Lin Zeng chose to plant the first giant plant on the ocean.

In the cities of China, the space for the growth of giant plants is very limited, and if it is selected in a remote area, the utilization value of giant plants may not be reflected.

Therefore, it is better to plant giant plants near the sea, and through faster ocean transportation, it can help the coastal cities to expand new island space.

The sea is wide, and a paulownia tree covers an area of several thousand square meters, which is inconspicuous, growing in patches, forming large islands, but it is just a small position on the open sea.

Lin Zeng took out half of the eight mangrove island plants and prepared to hand them over to the Danube Mountain Planting Base.

In addition to the paulownia trees that form the skeleton of the plant island, there are other plants, plump mangrove plants and the structure of the island.

For example, the giant white sand vine, which is refined from white bone soil as a native plant, has a huge root system similar to that of the giant tung tree, but the sea surface plant has slender vine branches, fine leaves like white sand, and the sponge grows only three to five meters high, coiled above the roots of the giant paulownia tree, as long as it is slightly flattened, it can form a solid white sand vine ground.

There is also a plant called the round eggplant giant tree, and the native plant is the common autumn eggplant tree. It does not refine the root system of the origin, but attaches itself to the giant paulownia tree to survive.

The root system of the giant tung flower tree can extend to the bottom of the sea for two to three hundred meters, and its branches are between thirty and forty meters high.

The giant eggplant can be planted on the thick branches of the giant paulownia tree, firmly adsorbing the trunk.

And the direction of its giant is its fruit.

Its fruit body is huge, the shell is round and hard, and the diameter of ordinary fruits is between three and seven meters, and some can even grow ten meters in diameter.

The fruit of the round eggplant giant tree is the best plant island dwelling.

The fruit is hollow inside, the fruit wall is about 20 centimeters thick, hard as iron, with a good sound insulation effect, the ripe round eggplant giant tree fruit, the skin presents a beautiful apple red, chiseled doors and windows, release the thick juice in the fruit, a little ventilation, you can live directly.

There is another characteristic of the round eggplant giant tree.

The juice in the fruit is a very popular nutrient for other mangrove island plants, which can promote the growth of other mangrove island plants.

The growth of mangrove forests is greatly affected by temperature.

The mangrove forests in China are not very tall, there are 10-15 meters of mangrove forests in Nanhai Province, and in the world, only mangroves in the equatorial region can reach 20 or 30 meters high.

The batch of mangrove island plants refined by Lin Zeng can adapt to the temperature of minus fifteen to forty degrees Celsius after the refining of runes.

It basically covers the eastern coastal areas of China.

Lin Zeng left the breeding space.

This time, Teton continued to refine eight kinds of plants without a break, which made him feel fatigue that he had not felt in a long time.

He needs to get out of the breeding space and give himself a little room to relax.

When leaving the breeding space, Lin Zeng called Pan Ruoming and asked her to send someone to pick up the seeds of mangrove island plants.

Pan Ruoming was eating the afternoon snack sent by Feng Yanming, processing the documents that had just been delivered, when he saw Lin Zeng's number flashing in his mobile phone, he was slightly surprised, raised his eyebrows, and answered the phone.

"Sister Pan......" Lin Zeng and Pan Ruoming rarely spoke politely, usually, they directly and simply explained the purpose.

It is rare that the boss who has not played a role for a long time has a work task, Pan Ruoming almost word-for-word memorized Lin Zeng's words about mangrove island plants, and the signature pen in her hand used a shorthand method that only she could understand to write down all the contents.

After Lin Zeng finished describing the mangrove island plants, Pan Ruoming's eyes narrowed slightly, and he seemed to have a lot of calculations.

She did not satisfy Lin Zeng's explanation in a few words, but spent a whole hour asking questions, thoroughly understanding the characteristics and attributes of the eight mangrove island plants, and then spoke, so that Lin Zeng could rest assured that she could properly arrange this matter.

When he hung up Sister Pan's phone, cold sweat broke out on Lin Zeng's forehead.

He felt that in the breeding space, refining eight kinds of plants in one go, he had not yet faced the pressure of Sister Pan's impenetrable interrogation.

It's weird.

Having been pregnant for three years seems to have nothing to do with the fierce Sister Pan.

Many of the questions she asked, Lin Zeng didn't take into account many of them, and when she asked, Lin Zeng had to temporarily run to the system to check the system to deal with it.

I don't know what tricks she will use to hand over the mangrove island plants to Sister Pan.
