Because the greenhouse cannot receive natural precipitation, the water required by the crops planted basically depends on artificial irrigation, so the need for water is relatively large. According to research, on average, the irrigation water required for an acre of greenhouse is about 100 tons a year.

For example, in the peak period of crop growth, the irrigation water required per mu per day may be as high as 1.3 tons, but in the seedling stage, the irrigation water required per mu per day may only be a few hundred catties.

In addition, the specific irrigation water required for different crops is also different, and the 100 tons required in a year is only an average.

Just like the three vegetables grown in the planting base, tomatoes and cucumbers require much more irrigation water than chili peppers.

But even according to the annual need of 100 tons of water per mu, these 60 acres of multi-story greenhouses require more than 6,000 tons of water per year, and the daily irrigation water source is nearly 20 tons, and the daily irrigation water demand is even as high as 80 tons during the peak growth period in summer.

The reason why Wen Yanran supported Kang Mingsong to change the original design plan was mainly because of the problem of water source. The spring in front of Cummingsong's villa generally produces only about 30 cubic meters of water per day, and the water output fluctuates very little throughout the year.

As a result, when the amount of water required in the greenhouse is small, the amount of spring water produced is abundant to a certain extent, but when the demand is at its peak, there is a big shortage.

Originally, the 100 cubic meters of water basin was not enough during the peak demand period, considering that the water output of the spring was only about 30 cubic meters, and the original plan was to divert water from another water source.

However, if according to Kang Mingsong's new plan, the two acres of paddy fields are transformed into a pond, even if the average water storage depth of the pond is only one meter, the water storage capacity of this pond is as high as more than 1,300 cubic meters, but it can be a good solution to the problem of irrigation water sources in the planting base, and there is no need to find another water source to divert water.

Moreover, the pond can also be planted with lotus roots, and even fish can be raised, so it will not cause a waste of land.

Of course, in the case of fish farming, it is also necessary to build a smaller pond next to the pond to separate the water used for irrigation, so that the fry in it do not follow the water into the irrigation pipe.

………………

In fact, today, this smaller pond is already being built, right next to the paddy field, with a designed storage capacity of 20 tons. At the same time, the pond is also under construction, and at this stage an excavator is being used to dig up the soil from the field and transport it to a depression in the planting base for landfill.

This project is a large amount of work, and it is expected that it will take more than half a month to complete.

In addition, after the deep excavation of the pond is completed, the surrounding area is hardened before entering the water storage stage.

Around the pool, Cummingsong plans to build some covered bridges for rest and fishing.

According to what Wang Weimin and Kang Mingsong said in a private exchange, if the backer wants to embark on the road to prosperity, he must walk on two legs. This leg is the development of industry, and the other leg is naturally the development of tourism.

After all, if you don't make good use of the beautiful environment that nature has given to the mountain township to seek a way to get rich for the residents of the mountain township, it is simply a crime.

If the rural tourism in the mountain township can finally develop according to Wang Weimin's plan, there will definitely be a lot of tourists who will come here at that time. Kang Mingsong, a pond located on the edge of the market town, and dozens of acres of planting base, is likely to become a scenic spot.

Of course, even if tourism in the mountain township cannot develop in the end, it is good to build this pond and use it for leisure and entertainment for yourself and your family.

It's just that all this is still in the plan, and it is impossible to implement it for the time being.

It takes a lot of money to build a covered bridge and water pavilion around this pond. After all, its length is nearly 200 meters, and even if it is a simple covered bridge and water pavilion, I am afraid it will cost tens of thousands.

Of course, the early planning can be done first, and it will be much easier to build at that time.

………………

Regarding Kang Dajiang's request for Kang Mingsong to choose some green trees to plant in front of and behind the house, Kang Mingsong did not have too clear requirements for this. On the one hand, he doesn't pay much attention to these things, and on the other hand, he doesn't have much research on them, so he doesn't have many ideas.

Thinking that Kang Dajiang was engaged in the construction industry, he should have some understanding of this, so he asked him.

After listening to some of Kang Dajiang's recommendations, Kang Mingsong chose to plant some cherry blossoms and plum blossoms in the yard, and some peach trees, plum trees and other fruit trees on the other three sides of the house. Not only can it be pleasing, but it is also affordable.

When you think of cherry blossoms, you immediately think of RB, because cherry blossoms are known as the national flower of RB.

However, this is a misconception, in fact, cherry blossoms were first planted by the Chinese. RB has only been planting cherry blossoms for more than 1,000 years, more than 1,000 years later than China.

Cherry blossoms are an important species of flowering trees in early spring, and when they are in full bloom, they are full of flowers and clouds, which is extremely spectacular.

The cherry blossom is also a symbol of love and hope, representing elegant, simple and pure love. Therefore, the cherry blossoms planted in the garden are not only beautiful, but also extraordinary.

In addition, he plans to plant some grapes around the pond and let them climb to the covered bridge water pavilion, which can be used as a kind of decoration for delicious grapes.

After walking around the villa, Kang Mingsong was very satisfied with the construction results, he also went into the villa to take a look, the interior decoration was also almost done, the style was exactly the same as the original design, the high-end atmosphere was high-grade, it seems that Kang Dajiang did not fool him, and used enough materials.

In Kang Dajiang's words, if it were in the city, just this set of decoration with a construction area of up to 300 square meters would cost no less than 300,000 yuan, and it would be a friendly price.

Since this uncle is so realistic, Kang Mingsong is naturally as kind as ever, so he happily asked Kang Dajiang for a bank account number, and directly transferred the remaining 400,000 yuan to him.

Both of them use the accounts of Jiangyu Rural Commercial Bank, a local bank in Jiangyu City, and provide large-value remittance and transfer services with a maximum of 500,000 yuan in a single transaction and a maximum of 2 million yuan per day. In addition, the mobile banking remittance fee is free of charge, and the service fee is free of charge.

Mobile banking transfer is fast, Kang Mingsong just completed the transfer, Kang Dajiang received a text message reminder that the money has arrived. He logged on to the mobile banking again and took a look, and found that there were 400,000 more in the account.
