Chapter 431 Cold-Proof Ditch

Xia Qing still doesn't know whether the protective gear made of snake skin with advanced hardness evolution is good or not. She can only deeply feel that the meat of this kind of snake is really hard, only harder than the hardness of Xia Qing's harvested yellow light. Soybeans are lower.

After Xia Qing finished the porridge, she felt only one thing: toothache.

She felt that the sick wolf's weak intestines and stomach might not be able to digest such hard meat particles and be unable to absorb nutrients from the snake meat. If you can't make porridge, you can only puree the meat into meatballs or make steamed meat before eating.

The blade of the noodle grinder she exchanged from the territory management department would definitely not be able to break such hard meat. Just when Xia Qing was wondering whether to ask Uncle Huo to help her build a special meat grinder at the cost of getting scolded. Zhang San’s phone number came over.

"Xia Qing, can you move the meat? I have a small meat grinder here. Can I send one to you?"

Where can I find high-quality idols from Blue Star? Huisan Base No. 7!

Xia Qing was overjoyed and thanked him immediately, "Thank you, third brother. I cooked a pot of meat porridge, and my teeth hurt when I bit into the meat. I was thinking of a solution when you called me."

Zhang San was in a good mood and his voice was very kind. "You can eat 100 kilograms of this giant python's meat this winter. No matter how much you eat, you won't be able to absorb the energy inside. You can exchange the excess snake meat for People who need it. If this meat is given to ordinary evolvers or ordinary people who have never eaten advanced evolutionary meat, the effect of improving their immunity and stimulating evolution will be more obvious."

Xia Qing immediately asked, "Third brother, do you still need it? If necessary, bring some more."

Zhang San smiled, "I have enough here. Try not to let too many people know the source of the snake meat. There are killer snakes in that place. Not only is it dangerous to catch snakes, but it may also be used by interested people to breed killer snakes in large numbers."

"I understand. Thank you, Third Brother, for reminding me." After Xia Qing thanked him, he asked about the big drop in temperature, "I heard that the lowest temperature this winter will drop to minus 30 degrees. Third Brother, can our wheat seedlings hold up?"

Zhang San responded, "According to predictions, this winter will indeed be colder than previous years. The specific extent to which it will drop depends on the amount of snowfall in Zhanxue. The wheat I gave you is a type of wheat with strong winter evolution. If it is cultivated, it will definitely be able to withstand minus 20 degrees Celsius. If the temperature gets lower, you need to take measures to prevent cold and keep warm. "

Zhang San didn't tell Xia Qing how to keep wheat warm. It should be that his heating measures were not practical for ordinary territories.

In the afternoon, when Xia Qing went to the greenhouse to plant leek roots, she asked her allies about keeping their farmland warm in winter.

What Qi Fu introduced was to put down the rainproof cloth of the greenhouse at night to prevent wind and keep warm, but Shi Mu mentioned a new method, "Before the natural disaster, when people in our village planted vegetables in the greenhouse in winter, they would dig a cold-proof ditch around the greenhouse and put foam boards inside. Or polystyrene board, and then fill it with sawdust, weeds, straw and other insulation materials, compact it and then cover it with soil to seal the ditch. It is said that it can increase the ground temperature in the shed by three to five degrees. "

Qi Fu's wife Yuan Yan immediately followed, "When my sister-in-law mentioned this, I also remembered it. When we drove a big car to the cold provinces in the north to pick up vegetables, we heard someone who grew greenhouses there mention this method."

Zhao Ze asked, "Now is the year of natural disaster. Are there any factories producing foam boards or polystyrene boards? I don't know how many points per pound."

Kuang Qingwei came online, "I'm going to ask about it, and I'll tell everyone about it later."

Xia Qing asked, "How wide and deep is this kind of cold-proof ditch?"

Shi Mu replied, "It seems to be forty centimeters wide and half a meter deep."

Li Si suddenly came online, "The depth of the cold-proof ditch is not a fixed value. It is directly related to the depth of the frozen soil in the area. It only needs to be about 10 centimeters deeper than the frozen soil."

Xia Qing asked quickly, "Fourth sister, how thick do you think the permafrost layer here will be this winter?"

Li Si's voice was still cold and cold, as if the quarrel between Shan Ying and Zhang San in the morning had no impact on her, "Seasonally frozen soil is a frozen soil layer formed due to temperatures below zero in winter. The thickness of the frozen soil layer is related to It’s related to the temperature. The lower the temperature, the thicker the frozen soil layer.”

"I don't have Huisan Base here. Data on the thickness of the permafrost layer in winter over the years. Calculated according to the dimensions, the permafrost layer at Huisan Base should be two to three centimeters thicker than Huiyi Base. However, our territory is located in the east, north, and south. Surrounded by mountains on three sides, the thickness of the permafrost layer should be one to two centimeters thinner than in other areas, so it should be comparable to the Huiyi Base.”

So, what is the exact thickness?

Xia Qing asked very clearly, "Fourth Sister, what was the lowest temperature at Huiyi Base last winter? How thick is the permafrost?"

Li Si directly gave "minus 13 degrees, 45 centimeters."

Qi Fu followed Xia Qing closely, "Fourth sister, the soil layer here is about this thickness, right? In other words, the soil layer here will freeze in winter?"

"Yes." Li Si responded affirmatively this time.

Zhao Ze asked, "Fourth sister, the soil is frozen, won't the wheat and rapeseed be frozen to death?"

Li Si replied, "No, the wheat variety you received in spring is M-11, which is a strong winter evolution variety and can withstand temperatures as low as minus 15 degrees Celsius."

Xia Qing concluded, "So, if we dig a cold trench, we need to dig through the soil layer?"

After Li Si gave a positive answer, Kuang Qingwei went online, "Everyone, it is said that this winter will be very cold. The price of foam board and polystyrene board has doubled from half a month ago, and it is not in stock yet. We can only pre-order. It’s not suitable for use in the ground. Brother Ying, you should buy some and stick them on the wall.”

The people in the No. 15 territory live in iron houses, which are not very effective in keeping warm. Yue Haiying responded, "Okay, I'll find a way to see if I can get some back."

"Even if we don't use foam boards, digging cold-proof ditches is definitely better than not digging. I plan to dig." Qi Fu has always spared no effort in farming.

Zhao's mother followed the farming expert, "I'll dig too. We dried a lot of hay this fall, enough to fill the ditches."

"I'll dig too." Although there are few people in Xia Qing's territory, she has a micro-tillage machine, so her digging speed may not be slower than others.

After planting chives and irrigating them with spring water, Xia Qing carried a basket and climbed up the northern buffer forest with the sheep boss and the sick wolf to cut the toon bells.

"Mee——"

This big toon tree with all its leaves fallen is the sheep boss's treasure. Seeing Xia Qing climb up the tree and take out the long branch shears, the sheep boss cried out and felt a little uneasy.

It thought Xia Qing was going to hurt the big toon tree.

"It's not about cutting down trees, it's about cutting the fruits of the Chinese toon tree, that's it." Xia Qing snapped and cut off a few bunches of Chinese toon bells, letting the sheep boss know what she was going to do.

When the sheep boss saw that Xia Qing was just cutting small branches for fun, he was no longer nervous. After sniffing the Chinese toon bells and finding that they were inedible, the sheep boss lost interest and went to gnaw on the dry Chinese toon leaves on the ground.

The sick wolf picked up a bunch of spring bells and put them in the basket, looking up at Xia Qing.

Xia Qing, who was standing on the tree, immediately praised, "Old Second is great, Old Second is so amazing, yes, I put all the ones I cut into the basket, we are going to take them home."

The sick wolf grinned, hahahaha.

The sheep boss, holding the leaves in his mouth, raised his head and looked at them for a few times, then continued to eat his meal with his head down.

"Sister Qing——"

Xia Qing, who was standing on the big Chinese toon tree, heard the shouting and turned around to see Hu Zi carrying a bicycle, standing outside the north gate of the No. 3 territory.
