Back in the 1980s, hiking in the mountains was also a way of life

The problem overlooked in Chapter 1209

Liu Guilan's words did not frighten her nephews; instead, they made them laugh even harder.

With Wang An's guidance, everyone had a clear idea of ​​what vegetables to grow in the greenhouse, and the previous confusion and anxiety disappeared from their faces.

After discussion, everyone agreed that one-third of the vegetable patch in the greenhouse would be planted with chives, one-third with spinach or rapeseed, and the last third would be used to plant cucumbers, persimmons, cantaloupes, coriander, and other vegetables that are not commonly seen in winter, according to each person's ideas.

The reason why the same type of vegetable is not grown in greenhouses is mainly because vegetables, like crops, cannot be grown on the same piece of land indefinitely.

For example, with chives, normal ground-grown chives need to be dug up after three years of growth and transplanted to another place. Otherwise, the chives in that field will wither and turn yellow, and the chive roots will rot.

Take scallions for example. If scallions are grown on a piece of land for a long time, the land will inevitably become infested with maggots, and the white part and roots of the scallions will rot, leading to a significant reduction in scallion production or even a complete crop failure.

The ground maggots mentioned here are small white insects that live in the soil and look very similar to maggots found on flies. They specifically feed on the roots of crops, leading to reduced crop yields.

After deciding what vegetables to plant, Wang Gan, the third brother who was very interested in greenhouse farming, suddenly asked Wang An:
“Xiao An, this morning when I got up and looked at the insulation blankets on the greenhouse, I suddenly remembered something. You know, it was fine before it snowed, but if it snows, it will be so hot inside the greenhouse and so cold outside. If the snow on the insulation blankets melts and then freezes again, won't the whole insulation blanket freeze into ice shards?”

After Wang Gan finished speaking, his elder brother Wang Shun also said:

"If the insulation blankets freeze into ice, they won't be effective at keeping the plants warm anymore, and the vegetables inside the greenhouse will freeze to death, won't they?"

To be honest, Wang An had overlooked this issue. The main reason was that the greenhouses he had seen in his previous life all used ready-made insulation blankets or felts, and the outer material of these insulation blankets or felts was waterproof.

At that time, only a very few large cities had plastic greenhouses, and special plastic greenhouse insulation blankets were simply a pipe dream.

Wang An pondered for a long time before saying:

"That's true. It's still manageable now that it's cold, and we can clear the snow regularly without much trouble. But if it rains next spring, it will be a real problem."

After Wang An finished speaking, Wang Li immediately said:

"Then just put another layer of plastic sheeting on top, and then cover those thermal blankets with the plastic sheeting."

No one spoke. Wang An looked at Wang Li with an expression as if he were looking at an idiot and said:
"That huge area of ​​plastic sheeting can't be covered by just two or three people, and it can't be rolled up. What if it rains or gets windy? Who can put the plastic sheeting over the greenhouse roof?"

After Wang An finished speaking, everyone frowned and fell silent, pondering a solution.

After a while, Wang Dazhu frowned and said:

"Then we'll have to figure out how to wrap the thermal blanket with a plastic sheet, just like we put a duvet cover on a quilt. But the problem is, we can't fix the seams of the plastic sheet. If we sew it up with needle and thread, the plastic sheet will definitely leak."

After hearing Wang Dazhu's words, Wang An's eyes lit up and he said:

"I understand. Just use a plastic sheet as a duvet cover to wrap the thermal blanket. Then, don't sew the joint with needle and thread. Just heat up the saw blade and heat the joint up."

The method Wang An described, even in later generations, is still considered a way to connect plastic sheets or seal plastic bags.

Of course, as time went on, special glue for sticking plastic sheets was developed, so attaching plastic sheets became a minor problem. After Wang An finished speaking, everyone looked at him with blank expressions, clearly not understanding what he meant.

Wang An didn't explain the principle either, but waved his hand and said:

"Alright, I'll buy the plastic sheeting tomorrow, and you'll see how I did it and you'll know what happened."

Seeing how easily Wang An spoke, everyone's expressions instantly relaxed.

However, Wang Dazhu said somewhat anxiously:

"Why wait until tomorrow? Let's go today. We're about to plant the vegetables, and it'll take a lot of time to cover them with plastic sheets and insulation blankets."

After being busy for almost 20 days, all Wang An wanted to do was sit on the kang (a heated brick bed) and play with his two little ones. So, after Wang Dazhu finished speaking, Wang An casually replied:
"That thing is just in time. We can't use the thermal blanket we had earlier, so we can get it later. Besides, as long as it's put on before it rains, there's no rush."

Wang Dazhu, who had seemed quite anxious, immediately calmed down after Wang An's words. In fact, he even nodded and said:

"That's true. The sooner you put the plastic sheet on the thermal blanket, the faster it will wear out. If you put it on later, it can last for a few more days."

Although ordinary plastic sheeting is much cheaper than greenhouse plastic sheeting, it also has obvious disadvantages. On the one hand, it is relatively thin, and on the other hand, its resistance to weathering and corrosion is far inferior to that of greenhouse plastic sheeting.

After discussing the matter, everyone chatted for a while, and then the relatives made excuses to leave. If nothing unexpected happened, these people would definitely be busy going home to collect manure, turn the soil, and plant vegetables.

It must be admitted that they were all incredibly motivated, wishing they could stay in the greenhouse all day long.

Of course, after everyone left, Wang Dazhu and his wife, along with Zhao Cuiyun, got busy, pushing carts full of pig and sheep manure into the greenhouse.

As for Shen Wei, she hasn't been to Wang An's house for two or three days. The main reason is that her mother-in-law is still in a coma. According to the barefoot doctor, Shen Wei's mother-in-law is currently going through a lot of hardship and it should only be a matter of one or two days before she dies.

While Wang Dazhu and the others went to collect manure, Wang An stayed inside without moving. Instead, he held Happiness in his left arm and Joy in his right, interacting with them very affectionately.

Wang An made faces as he spoke to the two little ones:

"Sneaking away, sneaking away, hahaha, it's flying, it's flying... how did it fly? Hahaha!"

After a while, Wang An muttered again:

"Two little bees, flying among the flowers, flying, flying, muah, flying, flying, muah. Hahahaha."

As he spoke, Wang An would occasionally touch the two little babies' foreheads or cheeks with his big lips.

Although the two little ones couldn't speak, they were still kept laughing by their dad.

It has to be said that Wang An looked like a complete idiot at that moment, which made Huang Li and Mu Xueqing next to him laugh.
