Siheyuan starts from a better life

Chapter 465, Talking about fish

According to Xu Damao's introduction, there are about 100 to [-] acres of land used for farming in the entire Hongxing Farm. There are more than [-] people on the farm. Not only do they cultivate [-] to [-] acres of land, but they also raise hundreds of pigs, plus dozens of pigs. There are hundreds of cows and sheep, not to mention chickens. That’s not just talking about a single chicken. When others talk about chicken sheds, they say hundreds at least in each shed. There are five chicken sheds, and the number of eggs produced every day is There are thousands of them.

Going further is the livestock breeding area. When he saw where the construction was starting, Jiang Yan said directly before Jiang Yan could ask Xu Damao: "The construction started on the feces treatment tank. There are more things to raise now. The previous septic tank was too small. Use it." Septic tanks can also prevent the generation of flies. After using septic tanks, the number of flies here has been greatly reduced, especially the cold water in the sheds for pigs, cattle and sheep. The livestock have been raised a lot recently, and the grounds have been cleaned. After cleaning and rinsing, the smell here is not as strong as before.”

"Now, thanks to the feed prepared by Professor Ding and others, a batch of pigs can be produced in eight months. Each pig can weigh about [-] kilograms, and the taste is the same as before."

At this point, Xu Damao said with a bit of envy: "Among this group of poultry, cows enjoy the most happiness. The concentrated feed they eat every day, sometimes they eat better than people. However, this also has advantages. The first batch of crossbred animals The beef cattle and dairy cows have grown up now, and according to Professor Ding’s speculation, the hybrid cows will be able to produce milk in another month.”

Hearing that the cows began to produce milk, Jiang Yan thought for a while and then said to Xu Damao: "Well, in the future, can you secretly get some milk for the old lady and the others to drink? Tell me how much it will cost. I will do it." pay."

Hearing that the cows started to produce milk, Jiang Yan's eyes rolled, and he said to Xu Damao: "Well, in the future, can you secretly get some milk for the old lady and the others to drink? Let me know how much it costs." I'll pay the number."

Due to material scarcity in this era, milk, like other non-staple foods, was in extremely short supply.In order to allow more citizens to drink milk, the government has included the dairy industry in the economic development plan, strives to increase milk supply, and vigorously develop the dairy industry.

At that time, in order to ensure that patients and infants could drink milk, newborn babies were registered and ordered milk with their birth certificates and household registration books, and those with serious illness were registered with hospital certificates.Not to mention minor illnesses and disasters, even the elderly find it difficult to drink milk.Old BJ people all relied on breast milk to feed their children, so drinking milk was quite a luxury at that time. Since there were not many brands of milk powder, this thing could also be purchased with tickets. Milk tickets once became a top commodity in the black market. Because Jiang Yan is a special talent, he only has three kilograms of fresh milk and one kilogram bag of milk powder this month.

The milk and milk products in Jiang Yan's space have been almost consumed in the past few years, so he decided to take advantage of the cow.

Jiang Yan's space originally had some milk and dairy products, but after several years of consumption, they have almost bottomed out.

Getting some milk is not a difficult thing at all for Xu Damao. Now that the Red Star Farm is run by Xu Damao like a railway, getting some milk is not a difficult thing.

"Boss, it's just some milk. I'll get it when the time comes. You don't need to pay for it." Xu Damao said confidently.

Sitting under a grass pavilion by the lake, Xu Damao brought tea and looked at the lake with the breeze blowing. This scene was quite pleasant.

"Boss, after walking around here, you can give me some advice." Xu Damao handed over a cigarette and spoke, but he looked like a child asking for credit.

But to be fair, under the leadership of Xu Damao and the cooperation of professors from Agricultural University, the Red Star Farm was managed quite well by Xu Damao. In this era when food and non-staple food are not abundant, it provided a large amount of food to the institute. As well as meat and eggs, because a lot of vegetables are grown, sometimes the research institute doesn’t even need to buy vegetables, which is the envy of many factories.

However, Jiang Yan still spoke. The first thing he said was about the Xingfu Lake. In Jiang Yan's opinion, there are very few fish here, only tens of thousands of catties per year. This is basically two to three thousand fish. Xingfu Lake If the lake covers an area of ​​150 acres, it will produce just over 60 kilograms of fish per acre.This is too few. In the previous life 60 years later, others had accomplished the feat of raising more than a dozen fish per cubic meter. If we use that ratio, it would not be hundreds of thousands of fish, but millions. Things.Jiang Yan thought for a while and then said: "The fry invested are too few. When Professor Ding comes in a few days, let him see if he invests another [-] kilograms of fry."

"Boss, Professor Ding said that this water is too thin and cannot support many fish, so they did not allow many fry to be released. After their observation, the fish here do grow very slowly. This batch of fry, these few The average monthly weight is less than one kilogram.”

Jiang Yan heard this and continued: "Then if we want to raise more fish, we just need to solve the nutrition in the water. I think the main fish species here should be carp, grass carp, and silver carp! Now! We can increase the number of grass carp and silver carp cultured."

Jiang Yan calculated in his mind that the ratio he gave now was less than half a bar per cubic meter, which could definitely be raised. Moreover, this amount would definitely be a waste of resources 60 years later.But they haven't practiced it now, and they don't dare to release too much at one time.In order to reassure them, some methods must be used to assist. After all, as long as there is a problem with the fish, they will die in large numbers very quickly. Jiang Yan does not dare to let them go without making preparations.

"First let's talk about oxygen. If there is no oxygen in the water, the fish will die soon, so we must first prepare the oxygen adding device. The oxygen adding device is very simple. One is an air pump, which can directly pass air into the water and increase the water content. Dissolved oxygen. We can use this as a backup equipment and only use it when fish have a large area of ​​floating heads to ensure that there will be no problems with the fish."

"The other one can be modified with a non-powered water pumping device. As long as the original water outlet pipe is changed into a circle with nozzles, it can add oxygen to the water like rain. We can install three or four unpowered water pumps per acre of water surface. The device is probably enough, so we can complete adding oxygen to the water."

"We can try raising them first. If the effect is good, we can continue to increase the breeding density. I estimate that our more than 100 acres of water surface can raise millions of fish. But we need to explore slowly in the future. This must be paid attention to. Yes, once the capacity of the oxygenation device cannot keep up, the losses may be huge. But I guess the problem shouldn’t be big.”

"And I saw that there are more than ten acres of open land over there, but there is nothing planted there." Jiang Yan asked, pointing to an open space near the hill.

"Oh! That piece of land was prepared by Professor Ding to plant grass. The seeds of the grass were just planted not long ago."

Jiang Yan's eyes lit up when he heard that pasture was grown over there. In fact, pasture can not only feed cattle and sheep, but also pigs, chickens, ducks, and fish.However, it mainly feeds grass carp. The more excrement produced by grass carp will inevitably fertilize the water, which will provide more food for silver carp. So we are feeding grass carp, and the water will naturally raise silver carp.

Jiang Yan guessed that this was the purpose of Professor Ding and the others to cultivate grass and invest in grass carp fry. It had to be said that this professor from the Agricultural University really had two skills.You should know that the yield of pasture is very high.Jiang Yan calculated that the annual output of pasture from these dozen acres of land should be at best ten tons. Even if it is hay, it can only produce several tons.

However, dealing with forage is a difficult problem. Jiang Yan thought about it and said, "I will design a few more machines for you in a while, mainly crushers, mixers, etc. These machines are very simple. I will draw a sketch later." , your maintenance staff will probably be able to make it soon, mainly because it requires electricity, which will probably save a lot of time in processing materials."

Xu Damao was extremely pleasantly surprised when he heard that Jiang Yan designed these machines for the farm.
