    The roar of the plane sounded, and Qin Shiou stood on a steep cliff on the coast and looked back. As the sound became louder and louder, the figure of the tractor in the air emerged from behind the woods.

    After this plane appeared, two more agricultural planes appeared. This was what Bill helped him contact. The establishment of a marine ranch is no simpler than a grassland ranch. In such a large area of ??sea, it would be too efficient to rely on just one airplane.  slow.

    Seaweed sowing has officially begun, but it is not seaweed seeds that planes are spraying now.

    Although every time you buy seaweed, you always use "seeds" to measure and call it. In fact, these are not seeds in the traditional sense. Seaweed does not produce seeds, but reproduces by dividing spores, and airplanes drop viable spores.

    Qin Shiou has seen agricultural companies cultivate seaweed spores before. They always use organic glass plates or plastic films as the spore attachment base. After collecting the spores, they are cultivated indoors using the inclined flow method. The embryosporophytes are cultured and then peeled off. Only then can they be released into the sea.  sowing.

    Because he was eager to produce results, the seaweed seeds he purchased this time were not microspores, but micro-mature spores that had been cultivated in farms. This type of seaweed was cultivated indoors using ropes as a substrate. After cultivation, the young sporophytes  It grows to 1 to 2 centimeters.

    An agricultural plane flew over, and Qin Shiguo held up a transparent umbrella and held it diagonally in front of him.  A group of fishermen shouted and looked for something to block them. Those who couldn't find anything turned their backs to the sea.

    After the plane flew to the sea, the injection port opened, and a white curtain appeared immediately. The fluttering white powder sprinkled down with thick smoke. After falling into the water, the sea water became more turbid.

    These things are lime, so they have to avoid them.

    The first batch of seaweed to be released is macroalgae. The sporophytes of this thing are very delicate and delicious. They are one of the favorite foods of sea urchins, starfish, and various benthic shellfish.

    There are two purposes of adding lime. One is to change the pH of seawater and inhibit the activity of organisms that eat macroalgae in the sea. The other is to have a bactericidal effect. There is no living water in the inner bay, and the metabolic rate of seawater is too slow, causing fish, shrimp, and seaweed to die.  After decay, it was not taken away and accumulated in these places to support a large number of bacteria.

    Seaweed is an expert in seawater purification, but their sporophytes are very sensitive. Why is it that the conditions in this bay are very suitable for the growth of seaweed, but not much seaweed grows on the seabed?  The reason is that there are too many bacteria here and many sporophytes cannot survive.

    The spores of macroalgae have strong cold resistance, so they can be released casually in winter and spring.  Now is the best time to put in macroalgae spores. According to time, the time when they grow fastest happens to be summer, when their needs for sunlight and nutrients reach their peak, and summer weather can just meet their growth needs.

    Three planes made two round trips, and the lime powder dropped covered an area of ??about hundreds of square kilometers. This area is the deepest sea. Beyond the continental shelf, macroalgae can grow in waters hundreds of meters deep.

    After lime powder is put in, the cultivated sporophytes must be put in. Of course, this is not like scattering seeds on land, just scattering these sporophytes.

    To a certain extent, macroalgae are a bit like plants such as loofah and grapes. They need to cling to something in order to grow faster. If they are floating in the sea, they will probably drift to nowhere after a few big waves

    Agricultural aircraft dropped pieces of submersible rafts, which are triangular and umbrella-shaped breeding rafts made of plastic frames and plastic ropes. Inside, there is a growth matrix for the rapid growth of macroalgae sporophytes, which can provide the initial stage for the sporophytes.  The energy required for growth can also become a clinging material for mature macroalgae.

    China uses the submersible rope method, which uses a plastic rope as a substrate and macroalgae attached to it. The two ends of the rope are fixed on the seabed to keep a certain distance between the rope and the seabed.  This method is simple and can adjust the cultivation water layer according to the transparency.

    Because macroalgae can be used to extract algin, make colorful plastics and fiberboards, and can also be used as raw materials for the pharmaceutical industry, macroalgae farming has emerged in Canada, the United States and Mexico despite the current poor fish farming environment.  This new ocean economic model.

    China has done a good job in this regard. Marine scientists successfully introduced macroalgae from Mexico as early as 1978. Many farms in the southern coastal areas have been cultivating macroalgae in recent years, and the profits have been considerable.

    Qin Shiou has read the information and found that China's macroalgae farming industry is developing very well. Domestic oceanographers have developed a set of macroalgae submersible raft farming technology.

    In this technology, the floating raft is lowered to the water through a rope connected to the raft to cultivate macroalgae. Now Canada and the United States have?Farms are using this technology.

    But he couldn't use such a technology, although it was a good one, because macroalgae are relatively sensitive to light and the sunlight intensity varies every day. In this way, by frequently extending and retracting the ropes to control the submarine raft, they can always be in the optimal water layer for breeding.  The best absorb sunlight and grow faster.

    This technology requires a large number of workers. Daqin Fishery cannot hire so many workers to adjust the position of the submarine raft. Moreover, it is not a professional seaweed farm. After the environment of this fishery improves, he will still raise fish.

    After the giant algae successfully survives in a sea area, it can change it into a submarine forest, covering the entire sea area, creating a natural high-quality fishing ground, which is very attractive to some precious seafood, such as tuna, sea cucumbers, abalone, etc.

    The type of submarine raft he purchased usually sinks 3 to 7 meters underwater after falling into the water. In early spring, the amount of sunlight in this water layer is more appropriate.

    After a while, as the giant algae grow, they will need more and more sunlight. At this time, there is no need for manual control. There are air sacs in the leaves of the giant algae. When they grow up, they will pull up the raft and slowly float up.  Adjust the water layer to grow.

    As the submarine rafts were launched one after another, Qin Shiou waved his hand, and the fishermen shouted to get on the Harvest, and then drove towards the sea. They were about to work.

    The next thing to do is to provide a climbing frame for the giant algae. As mentioned before, when the giant algae matures, the leaves will float on the water to absorb sunlight, but the buoyancy is ultimately limited, so it is better to provide a climbing frame.

    In addition, the climbing frame has a more important function, which is to collect the landing points of giant algae. In the future, these giant algae will be collected to make fish feed. It is convenient to collect them if they have a landing point.

    Qin Shiou has never done this job before. In the past, there was no need to provide a climbing frame when raising giant algae in the Daqin fishery. Anyway, the algae did not need to be collected. They could grow slowly and survive as they pleased.

    The purpose is different, and it won¡¯t work in Fishing Ground No. 2. The macroalgae have become an economic product, and they must be matured in the shortest possible time.  (Remember the website address: www.hlnovel.com
