Datang: God-level Choice

Although the most suitable area is Jiangnan Road, the land of water, it can also be promoted in other areas with water in Datang.

For a mulberry fish pond, you must first choose a place with water, plant mulberry trees on the ridge or near the pond, and dig a deep pond to use as a fish pond.

The principle is to raise silkworms with mulberry leaves, use silkworm sand and silkworm chrysalis as fish bait, and use pond mud as mulberry fertilizer to form a production structure or production chain of mulberry species in pond ridges, mulberry leaves for silkworm breeding, silkworm chrysalis feeding fish, and pond mud fertilizer for mulberry. , the two use each other and promote each other to achieve the effect of both fish and silkworms

Compared with other agricultural production methods, mulberry fish ponds have the following advantages: high economic benefits

By playing the role of the symbiosis and mutual support law between the material and energy circulation in the ecosystem, the effect of intensive management is achieved, which is in line with the economic benefit principle of obtaining the maximum output with the smallest input.

good ecological benefits

The biomass ratio of each trophic level in the food chain in the mulberry fish pond is appropriate, the input and output of material and energy are balanced, and the recycling of animal and plant resources is promoted, and the ecology is maintained in balance.

(Second update! Ask for full order!)

The most important thing is that Datang is known as the country of silk. There are many people who grow mulberry and raise silkworms. Many people make a living from it. The merchants have developed large-scale mulberry fields and silkworm raising workshops. , is an important part of Datang's current economy

Especially in some prefectures and counties of Jiangnan Province, almost every household raises silkworms and every household grows mulberries.

This group of people can first promote the mulberry fish pond. Since Jiangnan Road is the least water-deficient, it is very convenient to transform. With the gold medal of Qin Huai Road, I believe that the common people and businessmen will definitely cooperate actively.

And as long as the mulberry ponds of this group of people are successfully renovated, the income-generating figures come out, plus the propaganda of fishing boats such as newspapers, it will be difficult for the mulberry ponds to become popular or not.

In the Tang Dynasty, fish was still a relatively precious ingredient. Mencius' choice of fish and bear's paw fully illustrates this point.

Mulberry fish ponds can use silkworm cocoons, silkworm sand, silkworm chrysalis, and silk reeling wastewater as fish bait. The cost of raising fish is not high, and the profit margin is very considerable.

The fat mud at the bottom of the fish pond can increase the output of the mulberry field, and the delicious mulberry leaves can increase the output of silkworms spinning, which is another profit growth point.

"Sangmao, strong silkworms, fat fish, pond fertilizer, good foundation, and many silkworm cocoons"

This proverb fully illustrates the connection between the various links in the mulberry fish pond cycle production process.

Moreover, mulberry fish ponds can solve the problem of a lot of water accumulation in low-lying areas due to flood disasters in these areas, turning waste into profit, and can also play a certain role in maintaining soil and water.

Like Lingnan Road and other areas, if you are not used to planting mulberries and raising silkworms, you can also change mulberry fish ponds to fruit-based fish ponds, replace mulberry trees with fruit trees, and raise chickens and ducks in the fruit forest, which can also play a good role. Ecological chain, increase the income of farmers, and enrich the dining table of the people of Datang

"Once it is successful, there will be more Tang children in the future. Like our little children, they can often eat fresh fish and various fruits."

Qin Huaidao concluded with a smile

"Hmm, brother-in-law is the best"

The adoring eyes of a group of little loli made Qin Huaidao feel very good.

"My son-in-law is really fast!"

Li Er, who was invited by Qin Huaidao and came from the palace to visit the demonstration field of mulberry fish pond, was also very satisfied.

On one side, the high-ranking officials of the dynasty, like curious children, gathered around a few agricultural and forestry researchers and asked carefully.

"This mulberry fish pond is very good. Once it is promoted on a large scale, there will be more fresh fish in the market, and the price of this fresh fish will be reduced to a level acceptable to the common people."

Sun Simiao stroked his long beard and said, "According to the introduction of His Royal Highness King Qin and our research, this fish soup is rich in nutrients and has a good effect on the growth of children. It can be popularized by everyone."

"Previously, we planned to promote canned marine fish and fish bone meal to the volunteers in the government office. Now that we can have fresh fish, it is naturally the best."

"Indeed, the old minister likes fresh fish very much, but before, the price of fresh fish in Tang Dynasty was extremely high, and even the old minister was reluctant to eat more. Although there are frozen sea fish in the back, but after all, the feeling of fresh fish is missing."

Fang Xuanling is also Ying He Dao

Before Qin Huaidao made his fortune, the Tang treasury was unable to make ends meet. Although the prime minister's salary was quite large, there was no surplus to maintain a large family.

After Qin Huaidao took off, they all made a lot of money with Qin Huaidao, and the situation in the mansion improved a lot, but the cost is still relatively frugal, and fresh fish is not all you can eat.

"Haha, once the mulberry fish pond and fruit-based fish soup are promoted, the Ministry of Household can also raise a lot of taxes."

Tang Jian has already started to make a small calculation in his heart, calculating how much income the national treasury can increase.

In a word, the monarchs and ministers are very satisfied with the appearance of the mulberry fish pond, and it is a happy scene.

This group of veteran ministers who founded the country, after rectifying many times and excluding a group of dissident people, are still relatively dedicated

They are very concerned about people's livelihood, and they are deeply happy to have such good things now.

"By the way, my virtuous son-in-law invited me to come here today. It's not the only mulberry pond to see, right?"

Li Er looked at a group of important ministers who were stroking their beards, and then looked at his poor beard, and immediately began to nitpick.

"Of course, there are"

Qin Huaidao lengthened his voice on purpose.

"Hey, what new inventions are there, Sizi will see"

"Sister Sizi, you have the Jinyang Princess number.

Now, why is it Yuzhang's turn this time?"

"It should be from Chengyang"

When a group of little loli heard a new invention, their eyes suddenly lit up

If this mulberry fish pond is named, it will be called Chengyang Fish Pond or Yuzhang: Fish Pond, etc. It always feels a little strange, the little girls don't like it very much, they are depressed.
