Great time travel

1 Chapter Twenty, Wang Qiu's Choice

The roof terrace of this small villa on the Taililia Plain was built by Wang Qiu into a fixed solar panel greenhouse of more than 150 square meters using steel skeleton structure and polymerized transparent plastic panels.The purpose is naturally to create a slightly pleasing green environment for yourself on this barren, arid, and sparsely vegetated Talilia Plain, forming a healthy harmony between man and nature.

——There seems to be an objective law in this world, that is, the more something is lacking in the living environment, the more such things should be emphasized.

For example, the Mongols living on the Mongolian plateau are obviously one of the inland peoples in the world farthest from the ocean. Temujin Jiboerjin, who unified the nomads of the Mongolian plateau, insisted on calling himself Genghis Khan , that is, "Khan as vast and wide as the ocean"; and the Arabs and Persians living in the desert Gobi are obviously the least green in their lives, but in their religion and culture, they are so green. He loves green and regards it as the color of life, and is especially keen on building various beautiful gardens full of greenery.

On the contrary, there were many ancient Chinese who lived in green, and regarded green as a symbol of humbleness. Since the Spring and Autumn and Warring States Periods, green clothes have been considered to be worn only by servants.Since ancient times, according to the theory of "reincarnation of five virtues", Chinese dynasties have favored black, red, white and yellow, but never green.As for the green hat, green camp, green robe, etc., they are not good words.

In the same way, although Chinese people have always been famous for their jade culture, the jade that could be respected as a treasure in ancient times was always respected as "mutton fat white jade", followed by topaz and red jade.However, green jadeite, which is widely admired in modern times, has always been regarded as low-grade and "fake jade" by the ancients, but it cannot be sold at a high price.Until modern times, with the change of customs, green jade had a place in China's jewelry market.

Although they don’t like green very much, on the other hand, Chinese people have the best planting talent in the whole earth. No matter where they go, as long as conditions permit, they are often used to setting up vegetable gardens or flower gardens and trying to find ways to grow them. Something.Even if you stay in a metropolis with reinforced concrete forests, you often feel that the indoor environment is too monotonous, and you like to plant some flowers and plants and put them in the corner of the table—and Wang Qiu is no exception.

——In fact, for Wang Qiu, who lives in the wilderness and has nothing to do, tending these plants is also an important pastime to regulate his body and mind.

At this moment, when he pushed open the fiberglass-steel aisle door and stepped into the greenhouse on the roof, Wang Qiu immediately felt refreshed by the fragrance of grass and trees. A sense of refreshing pleasure: Only after staying in this gravel-filled Gobi desert for a long time, will you understand how precious this seemingly ordinary green green can be under certain circumstances.

As soon as you step into the greenhouse, you can see the surrounding area is a patch of green in different shades, even though it is picked by the owners every day, it still grows quite vigorously - Wang Qiu, who is seriously lacking in artistic cells, does not What flashy flowers and bonsai are planted in the roof greenhouse, but all kinds of fruit vegetables and edible spice plants are planted, the former includes coriander, pepper, lettuce, green vegetables, cabbage, onion, garlic, tomato, pea , cucumber, loofah and strawberries, etc., the latter includes mint, lemongrass, rosemary, basil and so on.

Although it looks a bit like burning pianos and cooking cranes, Wang Qiu is calm about this place. As a former reincarnation who has withstood the test of life and death in infinite space, he knows that only food and weapons can make people survive in harsh environments. Live while mere beauty and sophistication means nothing.

However, perhaps for the sake of cleanliness, or to show some kind of "high-tech" style, the roof greenhouse Wang Qiu built on the roof of the villa is not a simple flower pot and flower bed, but uses a The set of indoor plant cultivation equipment named "Family Hydroponic Farm" is actually a highly practical and comprehensive soilless cultivation technology, using nutrient solution and PVC pipes instead of soil and manure to grow fruits and vegetables.

In fact, soilless cultivation, which seems to be quite high-end and foreign, is strictly speaking nothing new.As early as 1859, German scientists (in fact, there was no Germany at that time, it should be said that they were Prussian scientists) had invented the earliest soilless cultivation technology, using nutrient solution to grow flowers and plants.However, due to insufficient technical accumulation at that time, it lacked practical significance.Therefore, it was not until after World War II that the US aircraft carrier began to use soilless cultivation technology to build a "sea hydroponic farm", so that sailors could eat fresh fruits and vegetables when they sailed to sea.

By the beginning of the 21st century, hydroponic flowers and vegetables had changed from a practical agricultural technique to a petty bourgeois fashion.

——In order to let those urban white-collar workers who run between car exhaust and reinforced concrete forest all day can still get fresh air indoors after busy work day after day, and even eat the pollution-free green that they planted by themselves For food, relevant businesses have launched a variety of balconies or indoor hydroponic equipment, which look like boxes with a semi-airtight structure, the small ones are similar to microwave ovens, and the large ones are equivalent to wardrobes.Seeds, water, liquid fertilizer, ventilation fans, growing sponges and PVC pipes are pre-installed inside.Just press a button to grow flowers or vegetables by yourself.If it is placed indoors without enough natural light, LED lights should be installed on the upper part of the hydroponic tank to replace the effect of sunlight.

The "family hydroponic farm" that Wang Qiu set up on the roof of the villa is actually similar in structure and style, but the scale is much larger. Eight hydroponic boxes were set up in one go, and each hydroponic box was long. Four meters, one meter wide, and two to three meters high, it is divided into many grids for planting different fruits and vegetables, and the roof has sufficient sunlight without LED lighting.In the gap under the hydroponic tank, an iron cage was also installed, and guinea pigs (guinea pigs) were raised as a source of meat. This cute little guy is a traditional delicacy of the Peruvians. It can be ready to be slaughtered, and the meat is tender and delicious, roughly between pork and chicken, and it can be fed with the branches, leaves and rhizomes left after picking fruits and vegetables.

Relying on this rooftop greenhouse with a large output, Wang Qiu’s family of five can not only achieve self-sufficiency, but also basically have surplus vegetables and fruits every day... For example, after adding the nutrient solution today, After adjusting the ventilation, Wang Qiu found that the latest batch of cabbage, tomatoes, cucumbers and coriander in the greenhouse were ready to be harvested.So, Wang Qiu harvested them all, put them in a rattan basket and took them out, and then dug up a few bunches of potatoes in a small piece of cultivated land in the backyard, and then made a rough estimate, leaving today's dinner and tomorrow's food The required amount of dishes is placed in the corner of the kitchen.The rest were put into a metal box by Wang Qiu, dragged to the open space outside the villa door and arranged.

Then, seeing that the time was almost up, he himself sat back in the rattan armchair under the eaves again, squinting his eyes lazily to rest.At this time, the sky was approaching dusk, and in the dim sky, the setting sun melted into gold, and the sunset was like fire, and the raging wind for a long time also subsided. The vast and magnificent Gobi wilderness, bathed in this gorgeous afterglow, seemed peaceful And comfortable.

After a while, someone riding an electric tricycle bumped along the dirt road connecting the fortress and the villa.
