Fertilizers are now in production, but it's not yet time for fertilization. This time, the large-scale production of chemical fertilizers is also planned to be stockpiled first. The southern side can still farm in winter, but the northern side is blocked by heavy snow and cannot be farmed.

Therefore, the large quantities of fertilizers produced now are stored first, and they will be planted and sold after the northern side is unblocked next year.

This time, the sweet potato has been harvested again, especially after the addition of chemical fertilizers, the sweet potato yield is nearly 10,000 catties per mu. This kind of yield is really exciting.

A batch of rice has also matured, and the yield of rice with a yield of about 1,000 per mu is also very good. Although it yields only one-tenth the yield of sweet potatoes, how can it be the same? The yield of rice is not comparable to that of sweet potatoes, and sweet potatoes are not as delicious as rice.

The high yield of sweet potatoes this time made the experts even more happy, and then planned to promote it. If the whole country is planted with such high-yield sweet potatoes, coupled with the fertilizer produced later, at least everyone will not have to go hungry.

And rice crackers, which are still very important now. Sweet potatoes are indeed high-yield, but eating too much will cause heartburn, and if you make sweet potato flour, it will be much less, so rice crackers are still very important.

What's more, no one is too much food. In a few decades later, when everyone will no longer be hungry, Mr. Yuan is still researching various high-yield rice. How can we despise the abundance of food in this age?

In this era, there is not so much food.

It is that the sweet potato leaves that have been planted for two seasons before are not enough to be distributed across the country, after all, China is too big. In such a big place, the sweet potatoes grown in two seasons are not enough. These sweet potatoes are also grown to eat, right? It is impossible to keep all of them as seeds.

Therefore, the seeds of sweet potatoes are not enough to be distributed all over the country, and at this time the importance of rice crackers comes out. Moreover, the rice crackers have just cultivated small seedlings, and it will take several years before the results. In the past few years between rice crackers being planted and bearing fruit, they have relied on high-yield sweet potatoes and rice to fill their stomachs.

Chemical fertilizers have not yet been promoted nationwide, so the Yunhe Brigade in Yunnan and Guangxi has no news of chemical fertilizers. But even so, after secretly fertilizing all of the Yunhe Brigade's planting fields with the help of the farm, the crops grew particularly well.

This time, after the rice is harvested, I am ready to plant sweet potatoes. I plant three crops a year, but I plant two crops of rice and one crop of sweet potatoes.

In fact, sometimes only two seasons will be planted one or two years apart, and then a few months will be freed up to raise the land. After all, it takes a lot of land and fertilizer to cultivate the land all the time. The more the land is planted, the thinner it becomes, and the crops that are planted will not grow well.

After harvesting the rice this time, everyone started ploughing the land again, and then burying the soil. After these fertilizers were composted by themselves, and after adding the fertilizer from the fertile land secretly added by Chen Xiayue, everyone began to grow sweet potatoes.

Sweet Potatoes People rarely plant sweet potatoes directly, they are all planted with sweet potato vines. These sweet potato vines were planted on a plot of land selected before. If these sweet potato vines are not enough to plant the collective plot, then continue to plant corn, peanuts, soybeans and the like.

Soybeans are fertile crops, so in general, soybeans will be planted in fields where there are not enough sweet potatoes to be planted. But corn and peanuts are less grown, and soybeans, unlike some ancient novels, can only be eaten by stir-frying or boiling. Can’t soybeans still be used to grind tofu?

Recently, due to the busy farming, the Zhang family has all gone to work in the fields. Chen Xiayue goes to help from time to time, but she does not count as work points. Not to mention that Zhang Chengchuan does not want her to work hard with her, even Liu Guiying does not want to.

Her daughter-in-law's work in the fields is not considered work points. What should she do if she is exhausted? What a loss.

So Chen Xiayue went to help deliver sweet potato vines behind Zhang Chengchuan, and left after an hour or so, and she would not go to work collectively like others.

Chen Xiayue's family also knew that she was busy with farming, so Chen Xiayue and her elder brother Chen Xiasong came over on the weekend to bring Chen Xiayue some food.

The conditions of the Chen family are good. Although some people in the city may not be able to live well, the Chen family is still doing well. This time, I was worried that Chen Xiayue and Zhang Chengchuan were too tired when they were busy, so I brought them something nourishing.

Chen Xiasong bought two catties of pork ribs, one catty of pork belly, and two grass carp to send to his sister. When he came, he also sent two catties of tofu. He knew that his sister liked tofu.

"Brother, come as soon as you come, why did you bring so many things?" Chen Xiayue was very surprised to see Chen Xiasong bring so many things, although her parents' house gave her something from time to time, she also sent it from time to time I ordered something to go back, but this time I brought too much, right?

Two catties of pork ribs and one catty of pork belly are more than enough, and there are two grass carp with about two or three catties, which is also very expensive.

"Brother, why did you bring so much kelp to me? Is it too much?" Chen Xiayue was even more surprised when she saw the dried kelp that was about half a sack. The Yunhe Brigade did not rely on the sea and wanted to eat seafood. What is also very difficult.

Only dry food like seafood and sea vegetables can be eaten, and the price is quite expensive. Most people can't afford seafood. These things are not too expensive in coastal areas, but they are very expensive in inland areas.

Kelp is also very expensive in Yunhe Brigade and in the county town, and the price is more expensive than eggs. So where did this little half-sack of dried kelp come from? How much did it cost?

"These kelp were sent by my uncle." Chen Xiasong also knew what his sister was thinking, and knew that she felt that the family was too expensive.

but--

"These kelp were collected by my uncle in the fishing village, and the price is not that expensive, just like the ordinary vegetables grown in our own home. Uncle collected a lot of dried kelp and sent a lot to his family. In our family, my uncle sent a sack." Chen Xiasong said with a smile.

"Uncle, why did he buy so much?" Chen Xiayue was surprised to send it. In this era, fishermen are not easy to do, and the fishing boats are not so good. If you want to catch seafood, it can be regarded as life and death.

Kelp is not as valuable as other seafood. If you are lucky enough to find a good kelp bush, you can pick a lot of kelp and bring it back to dry.

But why did Uncle Chen buy so much kelp in one go? It's just a sack of kelp for her mother's family. What about the other rooms in the Chen family?

"It just happened that my uncle took it there and bought a lot of things in the name of the unit. These kelp are just extras that he bought himself." Chen Xiasong said, "It just so happens that the kelp is also very nourishing, you often use it to stew soup, It's good for the body."

Chen Xiayue looked at the dried kelp and nodded, "Okay, I will often make kelp to eat."
