The lake in the first crater had dried up completely, and the surrounding ring of moss, which was a kilometer wide, and the moss belt that spread to the sides of the crater, began to turn yellow. The pen "Fun" Pavilion www.biquge.info without enough water, even the tenacious moss will die.

Seeing this, Jiang Yiming canceled the action of continuing to green Mars, but stayed here, artificially selecting extremely drought-tolerant varieties. Only when new varieties are selected can the greening of Mars proceed, otherwise it will be useless.

Because he can only take care of one crater by himself, he gave up the first meteorite, and there is no water here, and it is a waste of time to stay here.

When Jiang Yiming arrived at the second crater, he found that the lake was only more than three meters deep and covered an area of just over 1,000 square kilometers, a 90 percent reduction from its heyday. It was a race to get the crater up to be sorted before the water inside the crater had evaporated.

He unfolded the legendary realm, enveloping the moss around the crater, giving them generation after generation, picking the most drought-tolerant moss to keep in his seeds. When the lake is completely dry, we go to the third crater and once again urge the moss species to grow.

If the United States, which has the most advanced biotechnology on earth, is allowed to do it, even if all the biological scientists are gathered and they start breeding, I am afraid that Jiang Yiming will not even be able to speed one-thousandth.

Because the existing biotechnology on the earth can only shorten the growth period of plants by one-third at most, and the effect is pitifully low. It takes a lot of time to get the next generation of drought-tolerant moss seeds.

Jiang Yiming waited until the water in the thirty craters was all dry, and he already had a kind of moss on hand that was thirty times more drought-tolerant than that of No. 150. Just give a drop of water every day to keep the fist-sized moss alive.

Of course, there is a downside to this, that is, the material of this moss becomes drier and looks wilted. It's just that he doesn't care what the moss looks like, as long as he can survive Mars.

Without Jiang Yiming's order, Qiming only pulled fifteen solid ice asteroids to the orbit of Mars, and did not push them to the surface of Mars.

Jiang Yiming ordered: "Push it down one by one!" ”

Rumble! The bottom of a crater was filled with water, and the splash of water soaked the ground within a radius of twenty miles. The moss seeds that have been sown take advantage of the abundance of water and grow freely, and soon expand to wherever there is moisture.

As the solid ice asteroid slowly fell, the desolate and dead red surface of Mars appeared in discontinuous green areas, which looked fragmented.

If you see such a scene on earth, no one will be excited, only that it is extremely barren and not suitable for human existence at all. But if you change the location to Mars, these green patches are like heaven, a place of hope.

"You've made a preliminary success! With plants, animals can be raised, and then nature's decomposers can be dispersed, and the natural cycle can be realized step by step. "The dragon Orsius was amazed, as if he had seen a junior pro triumph over a master pro.

Jiang Yiming had no pride on his face, it was so difficult to cultivate an improved type of moss, let alone create a complete biosphere. Only by experimenting with oneself can we know how complex the earth, with millions of species of creatures, is, and it is a rare treasure in the universe.

"Where, it's still far away, the more creatures there are, the more likely it is to collapse. Because now there is only a single producer, it is too unsafe. ”

Now is not the time to stock bryophytes, because if mosses become infected with disease and die en masse, the entire food chain will collapse.

"Yes, there has to be a variety of plants as producers to provide different kinds of food for herbivores."

Although Orseus was also very interested, he was eager to try, "I'm going to transform a kind of grass so that it can survive on Mars, it's called Orseus." How about the name? ”

Of course, Jiang Yiming would not refuse the dragon's obligation to help, and he wished that the dragon would have fun and always help. Therefore, he sent a series of good words: "Wow, in the future in the history of Mars, your name and your works will always be left behind, and the people here will be passed down from generation to generation." So how can it be enough just for Orrgrass, there must be Orr ants, Orr fungi and so on. ”

"Haha, I have to say, you said this to the bottom of my heart. Being able to leave a lasting mark in a world sounds great, great! "Orseus asked for the Light Leaf Purple Flower Seed from Jiang Yiming.

This grass is a very drought-tolerant herb on earth, and it is very suitable for being the original female parent. It is an annual or perennial herbaceous plant with a thick taproot, a depth of 1.5 meters into the soil, well-developed lateral roots, strong water retention, many nodules in the root system, and strong nitrogen fixing ability.

Purple flower likes cold and humid climate, cold and drought resistance, can resist low temperatures of minus 10 degrees, stop growing at 3 degrees, growth above 25 degrees is inhibited, and 10 to 21C is the best growth temperature. It can grow normally on all kinds of soils, and is not resistant to flooding, cold and drought during growth.

It is rich in nutrients, soft grass, good palatability, can be used for green fodder, can also be made of green hay or made into silage, is an excellent green fodder and protein supplement for livestock in winter and spring, much more nutritious than moss.

Jiang Yiming did not sit idle, but chose Huangzhu grass as the third plant to start a new round of breeding.

Boom, boom, boom, the three space shuttles spewed a stream of blue ions hundreds of meters long in their tails and entered the orbit of Mars. While investigating the safety of the landing site, it also continuously collects various information about Mars, from atmospheric composition to temperature, and air movement.

The three shuttles are from NASA because the United States has the most advanced space technology and experience. After obtaining the Ark reactor technology, in order to seize the opportunity, the United States did not have time to wait for the new spacecraft to be built, so it directly modified the retired space shuttle, and installed the Ark reactor and headed for Mars.

Probably God willingly, the three antique space shuttles all arrived safely on Mars, which made everyone at the space center in Houston breathe a sigh of relief, and everyone was excited.

"God bless America! We are the second country to land on Mars, and we are bound to have a head start in the space race. The United States will occupy a large part of the equatorial regions where resources are abundant and the temperature is relatively high. ”

"That's right, taking advantage of the fact that China and the European Union, as well as the alliance of Russia and South Korea, will immediately occupy the best territory and let the Americans occupy the essence of Mars."

"Hey, what's that green spot that the shuttle just skimmed, take a closer look!"

The three space shuttles aimed their advanced reconnaissance equipment at the small plain-like green space on the ground. So everyone in Houston saw that the green space was covered with green moss, which was very incongruous with the red Martian ground around it.

"It's hard to believe that in just a few days, New Australia has greened such a large piece of land!" All the American aerospace experts in Houston were shocked, and it was a long time before someone spoke. (To be continued.) )
