Seeing that everyone looked like they were taken for granted, Li Zhao was also very helpless, there was no way, the countryside was too poor now, and many things could not be promoted. Let's just say that these kinds of equipment, are very simple, the crusher or lawn cutter, is a shelf, plus a motor, and then the motor is connected to a knife holder, fixed on the knife, and then surrounded by a thin iron plate around the knife holder, or even an iron sheet, as long as the design turns the speed, it is completed.

Then there is a mixer, it is simpler, there are vertical and horizontal, the vertical type is a large drum, put on the shelf, the motor is fixed below, and then a shaft is made in the middle of the cylinder, several mixing blades are fixed on the shaft, and the pulley is installed below, and then the motor drives the pulley to stir, as long as the outlet is left on the cylinder, it is basically completed. The horizontal type can do the same principle as the vertical type, and it can also be made into an outer cylinder that can be rotated, in short, it is very simple.

The more complicated one is the granulator, but it is only relative, one is to directly feed the material with a screw and squeeze out the material, which is more complicated, and Li Zhao is not ready to do it. The other simple is that the motor drives the grinding disc and pressure roller to rotate, and there are small pits on the grinding disc, and after the material is down, the grinding disc and pressure roller will rub the material into particles.

Li Zhao also did what he said, and quickly drew a sketch of several equipment, and the transmission is driven by belt, which is simpler to make and lower in cost, as long as the proportion of pulleys is calculated, deceleration is also very simple. At this time, Division Commander Zhang also asked the guards to take the sketch to the maintenance department and let them see if they could make it.

"Finally, I have to emphasize that this pest and disease, fish farming is very different from raising other animals, that is, once you get sick, the death rate can be very fast, and the farm can only cooperate with experts in the university to let them study solutions, and I don't have a very good solution here."

"This way we can roughly calculate our inputs and outputs. As far as I know, grass carp can grow about three catties a year when there is enough food, and the daily diet of grass carp is about 3% of body weight. ”

"If we put in the fry according to two or two to calculate, the annual production time can reach about 270 days, so that we can get a formula, 0.1 * (1 + x) 270 = 3, then the daily growth of grass carp can be calculated, about 1.3 percent."

"According to the daily food intake is 3% of body weight, the amount of food eaten per year can also be calculated, about ΣM=0.1*3% (1.0131+...+1.013270), and the final result is that each fish eats about seven catties of food per year, and if we stock 200,000 grass carp, we need to put about 700 tons of feed."

"You can ask the experts how to breed, and I won't say more. However, in the end, it is estimated that no less than 140,000 fish can be obtained, which is about 420,000 catties. Silver carp feed mainly on plankton, and I can't be sure that we can only know how it looks if we look at the actual situation. When the fish are used to feeding, fishing is also simple, as long as the fish are fed, prepare the net, put it in the water first, and then feed the fish to start the net..."Li Zhao showed a smile that everyone understands at this time, and everyone also understands this meaning.

Hearing the figures given by Li Zhao, where could the people present be calm, they couldn't help but discuss, the data given by Li Zhao was a little scary, they had been guarding this lake for several years, but they never thought that it was possible to raise so many fish here. In particular, the final calculation made everyone feel both incredible and reasonable, and it was impossible to refute it.

At this time, Li Zhao directly gave all the conditions needed for fish farming, and even calculated the amount of feed needed, which seemed to be very reliable, and it was estimated that the difference was not much. And combined with the formula given by Li Zhao, the amount of feed required per day can also be roughly calculated, which is simply too important for breeding.

In fact, these were calculated by Li Zhao when he was in college, and the amount of fish he occasionally saw on the Internet, which he had calculated as early as when he was planning the development of Lijia Village. But seriously, agriculture in this era is really too far from sixty years later, and Li Zhao just casually came up with ideas in a few aspects, which can bring great development to the corresponding places.

Let's just say that if there is such a large area in 60 years, and the farmers are willing to invest money, it is not uncommon to raise two or three million catties of fish. It's just that this era is unlikely, and Li Zhao doesn't dare to take such a big step, it's okay to raise it well, if there is a problem, Li Zhao can't afford the consequences. Therefore, Li Zhao not only gave the aeration plan, but also reduced the breeding amount to the point of raising one fish in ten cubic meters, which is a hundred times lower than that after 60 years, which can no longer be said to be conservative, which leaves a hundred times the space for further development.

If the people on the farm slowly experiment with the density of breeding according to Li Zhao, they may also reach a higher amount in the future, and as they become familiar with breeding, it is impossible for people here not to see the potential of breeding here.

After everyone discussed for a while, Li Zhao continued: "In this case, there are several problems that still need to be solved, the first is that the silt in the water is estimated to be cleaned up every year, otherwise the silt will accumulate very quickly." The second is the breeding technology, you need to discuss with relevant experts, what diseases the fish is prone to, you still need to explore by yourself, but the method I give is absolutely feasible, this is the maximum artificial intervention in the growth process of the fish, to give the best living environment. ”

Having said that, the leaders of the farm, as well as these people in the military region, are all moved, it is very simple, such a breeding project is really moving. Looking at what Li Zhao meant, it is estimated that the input grain should not be much, otherwise this project would not be said in such detail, it is simply a copy of ecological agriculture when raising earthworms, which is absolutely necessary to operate.

"The second project I think is mushroom farming, you also saw it in Lijia Village, Lijia Village has done that experiment, and mushrooms are already coming out of it, and that can also be done. Not only that, but we can also engage in the cultivation of fungus, shiitake mushrooms, and even Ganoderma lucidum. ”

"Mushrooms are estimated to be the most troublesome of these kinds, the village is now experimenting with what to use as the base material for cultivation, it is estimated that it will take a lot of time to test, only the right base material, temperature, humidity can ensure that the mushrooms grow fast and good. In the future, we will expand the scale of planting, and the farm can also follow suit. ”

"And the fungus should be the simplest, as long as it is compared with the wild fungus, to ensure humidity, choose the same tree species as the wild fungus, dry it after cutting, and then soak it in water to inoculate the fungus, and usually pay attention to sprinkling. It is said that the cultivation of shiitake mushrooms and ganoderma lucidum is best done with oak wood, which is actually similar to fungus, and you can also consult experts. ”

"The third is a vegetable greenhouse or glass greenhouse, you should have heard of this, you can directly find a place to learn technology, I don't have an axe, they must be more professional than me."

Speaking of this, Li Zhao glanced at everyone, and then said: "The reason why I chose these things, I think you can also understand, fish farming is to make full use of the lake water, and to plant fungi, I think it can be placed on the hillside, or on the rocky beach, even if these places are planted with fruit trees, it will not affect our cultivation of these things." The vegetable greenhouse is to directly rebuild your vegetable field, so that you can have vegetable output all year round, the consumption of the army is huge, if your hundreds of acres of vegetable land are all rebuilt, the investment is estimated to be not small. ”

After Li Zhao finished speaking, the conference room burst into warm applause, Li Zhao's opinions, coupled with the ecological agriculture that has been implemented, this is simply rubbing the previous farm model on the ground. Especially fish farming, depending on Li Zhao's meaning, he is going to use mainly pasture, so it is estimated that there is a land of three to five hundred acres that can provide sufficient food, and if all the projects of the farm are implemented now, the output value of this farm is unimaginable.

Of course, for the military reclamation farm, what is more meaningful is that people can be arranged! It seems that there are not many people in fish farming, and it is estimated that one or twenty will be enough; But fungus planting needs a lot, now the farm still has thousands of acres of rocky beach, if these are used for fungus planting, it is not the need for hundreds of people to work, these are not easy to use machinery to sow and harvest.

Then there is the vegetable greenhouse, they originally intended to do it, this time Li Zhao proposed it again, which means that he is also extremely optimistic about this industry, so it is more necessary to engage in it, Li Zhao's vision is absolutely no problem.

There is basically nothing to do here, most of these people have to go to work the next day, so they leave separately by car, of course, Li Zhao also told his father to pay attention to strangers entering the village.
