Chapter 460, Speaking of Fish

Through Xu Damao's introduction, there are about four or five hundred acres of land for cultivation in the entire Red Star Farm, and there are more than 100 farm personnel, not only planting four or five hundred acres of land, but also raising hundreds of pigs, plus dozens of hundreds of cattle, sheep and 100 sheep, not to mention chickens.

Further ahead is the livestock breeding area, see where the construction is starting, before Jiang Yan asked Xu Damao directly said: "The construction is the manure treatment tank, now there are more things, the previous septic tank is too small, with the septic tank can also avoid the production of flies, after using the septic tank, we have a large number of flies here, especially the pigs, cattle and sheep in these sheds have taken cold water, livestock have been raised a lot recently, and the site is cleaned and then rinsed, the smell here is not as big as before." ”

"Now because of the feed prepared by Professor Ding, a batch of pigs can now be slaughtered in eight months, and each pig can reach about 300 catties, and the taste is the same as before."

Speaking of this, Xu Damao said with a little envy: "In this group of poultry, the cattle are the most blessed, the concentrate feed they eat every day, they eat better than everyone when they have time, but this is also beneficial, the first batch of hybrid beef cattle and dairy cows have now grown up, according to Professor Ding's speculation, in another month, the hybrid cows can produce milk." ”

Hearing that the cows began to produce milk, Jiang Yan thought about it, and said to Xu Xu Damao: "This, can you secretly get a little milk for the old lady to drink in the future, you tell me how much it is, and I will pay it." ”

Hearing that the cow was starting to produce milk, Jiang Yan's eyes purred and rolled, and he said to Xu Xu Damao: "This, can you secretly get a little milk for the old lady to drink in the future, how much money will tell me, I will pay." ”

In this year, milk was in great short supply, as was other non-staple foodstuffs. In order to make milk available to more people, the government has included the dairy industry in its economic development plan, striving to increase the supply of milk 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 with birth certificates, household registers, and serious illness numbers with hospital certificates. Not to mention minor illnesses and disasters, it is difficult for even the elderly to drink milk. The old BJ people rely on mother's milk to milk their children, so drinking milk at that time was a rather luxurious thing, because there are not many brands of milk powder, this thing is also purchased with tickets, milk tickets once became a top commodity in the black market, as far as Jiang Yan's because he is a special talent, there are only three catties of fresh milk this month, as well as a bag of milk powder supply.

And the milk and milk products in Jiang Yan's space have been almost consumed in recent years, so he started the idea of this cow.

Jiang Yan also originally got some milk and dairy products in the space, but after a few years of consumption, it has almost bottomed out.

Getting some milk is not a difficult thing for Xu Damao at all, and now that this Red Star Farm is run by Xu Damao, it is not a difficult thing to get a little milk.

"Boss, isn't it just a little milk, I'll get it when it's time, I don't need you to give extra money." Xu Damao spoke quite confidently.

Sitting under a grass pavilion by the lake, Xu Damao brought over the tea, looking at the lake, blowing the breeze, this scene was quite comfortable.

"Boss, take a walk around this circle, and you can give advice." After Xu Damao handed over a cigarette, he opened his mouth, but how to look at him like a child who invites merit.

But let's be fair, under the leadership of Xu Damao, coupled with the cooperation of professors from the Agricultural University, this Red Star Farm is managed quite well by Xu Damao, in today's era when grain and non-staple foods are not rich, a large amount of food and meat and eggs have been provided to the Institute, and because a lot of vegetables are planted, sometimes the Institute does not even have to buy vegetables, which is the envy of many factories.

However, Jiang Yan still opened his mouth, the first thing he said was the matter of this happy lake, in Jiang Yan's opinion, there are very few fish here, only tens of thousands of catties per year, which is basically two or three thousand fish, and the happy lake is calculated according to one hundred and fifty acres, and the fish production per mu is only more than sixty catties. This is too little, sixty years later, in the previous life, others have made the feat of raising more than a dozen fish per cubic meter, if according to that ratio, it is not a matter of hundreds of thousands of fish, it is a matter of millions.

Jiang Yan thought for a while and said, "The fish fry put in are too small, wait a few days for Professor Ding to come, let him see if he can put in another 50,000 catties of fish fry." ”

"Boss, this Professor Ding said that the water is too thin to raise many fish, so he didn't let many fish fry go. After their observation, the fish in this batch do grow very slowly, and this batch of fry has averaged less than a pound in the past few months. ”

Jiang Yan heard this, and then said: "Then we want to raise more fish is to solve the nutrition in the water, I think the fish species here, I think it should be carp, grass carp, silver carp three kinds of main!" Now we can increase the number of grass carp and silver carp farmed. ”

Jiang Yan calculated in his mind that the ratio he was giving now was less than half a piece per cubic meter, which must be able to be raised, and this amount would definitely be a waste of resources if it was looked at sixty years later. But now it has not been practiced, and they don't dare to put too much at once. In order to reassure them, they have to come up with some methods to assist, after all, as long as there is a problem with the fish, it will soon die in pieces, Jiang Yan does not dare to let them go directly without preparation.

"First of all, let's talk about oxygen, without oxygen in the water, the fish will die quickly, so we have to prepare the oxygen device first. The aeration device is very simple, one is an air pump, which can directly ventilate air into the water, which can increase the dissolved oxygen in the water. This can be used as a backup device when the fish has a large area of floating head to ensure that the fish will not have problems. ”

"The other can be changed with a non-powered pumping device, as long as the original outlet pipe is changed to a circle of spouts, you can add oxygen to the water like rain. Let's build three or four non-powered pumping devices per acre of water surface, and it is estimated that it will be enough, so that we can add oxygen to the water and complete it. ”

"We can try to raise it first, if the effect is good, we can continue to increase the breeding density, I estimate that we can raise millions of fish in this more than 100 acres of water surface." However, it is necessary to explore slowly in the future, which must be noted, once the capacity of the oxygenation device cannot keep up, the loss may be large. But I don't think it's a big problem. ”

"And I saw that there were still more than a dozen acres of vacant land over there, and there was nothing planted in there." Jiang Yan asked, pointing to a clearing near the hill.

"Oh! That piece of land was intended by Professor Ding to be used to grow pasture, and the seeds of the grass had just been planted. ”

Hearing that the grass planted there was pasture, Jiang Yan's eyes lit up, in fact, the grass can not only feed cattle and sheep, but also pigs, chickens, ducks, and fish. However, it mainly feeds grass carp, and grass carp produces more excrement, which will inevitably make the water fertilized, so that it can provide more food for silver carp, so we are equivalent to feeding grass carp, and the water naturally raises silver carp.

Jiang Yan guessed that this was the purpose of Professor Ding's forage grass and the purpose of putting in grass carp fry, and I have to say that the professor of Agricultural University really has two brushes. It is important to know that the yield of forage is very high. Jiang Yan calculated, the annual output of these more than ten acres of forage grass is best ten tons, even if it is hay, it can produce several tons.

However, dealing with forage is a difficult problem, Jiang Yan thought about it, and said: "I will design a few machines for you in a while, mainly crushers, mixers, these, these machines are very simple, I will draw a sketch in a while, and your maintenance personnel are estimated to be able to make it soon, mainly to use electricity, which is estimated to save a lot of time for processing materials." ”

Hearing that Jiang Yan designed these machines for the farm, Xu Damao was pleasantly surprised.
