After carefully reading Zheng Linchu's reply, Xue Langjing made up her mind that this investment was not as much as she imagined.

It is definitely more cost-effective to build such a pond than to sell pig manure directly.

Therefore, she mentioned the proposal that Zheng Linchu gave herself to everyone.

Now everyone in the Xue family can be said to have great trust and respect for Zheng Linchu.

After all, every time their family gets rich, it is related to her, if it weren't for her, how could they earn so much silver, of course, they are convinced of her words.

And the idea she came up with just solved their problem.

In the past few days, in order to solve the problem of storage and where to store pig manure, they have worked hard, and they are either looking for this or contacting that all day long, looking for people everywhere.

With her method, they don't have to worry about pig manure, and they can also bring more income to the family.

It's easy to say, it's basically a pond of more than 20 acres.

The main expenditure is the purchase of land, the digging of ponds, and the investment in the seed of fish, which is not too expensive.

So how to turn pig manure into treasure, both as fertilizer and feed?

Batching.

Build at least three types of ponds.

The first pond breeds cress, directly pours pig manure into the pond, and uses the nutrients in the pig manure to make fertilizer for the cress, which basically does not need to be put in fertilizer, and the cress can absorb the nutrients in the pig manure.

When the nutrients in the pig manure water are absorbed by the cress, there will be a lot of sediment left, which will become sludge after a long time, and if these sludge are not solved, they will accumulate more and more, and finally overflow the entire pond, and it will be troublesome to dispose of the sludge at that time.

So you can put snails in this pond to digest the sediment.

In this way, as long as the cress is planted and the snails are put in, you only need to pour pig manure into it regularly, and you don't have to worry about anything.

Just wait for the cress to grow and cut it off.

The same goes for snails.

Of course, it is not only possible to grow cress, but also other aquatic crops, such as water lilies, callus white, and so on.

The reason why he chose watercress is because Zheng Linchu considers that it can be planted all year round, and it can be cut one stubble after another, and it can be cut several times a year.

And it has strong decontamination ability, good water purification effect, and the best comprehensive benefits.

After the water has been 'treated' with cress and snails, it can flow into the next pond.

The second pond is planted with water chestnut, which has extremely long roots that absorb the suspended solids in the water and remove pollutants from the water again.

Although the snail can digest the sediment, it is not guaranteed to digest all the sediment, so how to deal with the remaining sludge, as long as there is sludge, it is easy to breed all kinds of insects, which will affect the growth of water chestnut.

You can put crucian carp, blackfish and other fish in the pond to let them catch bugs, which happens to save them feed.

After the treatment of the second pond, it can be transferred to the next pond.

The third type of pond can be planted with lotus, gourd and other green plants to purify the manure water again.

In the pond of the seeds, you can also raise yellow eels, loaches, pollution control effect is more, and there can be additional income.

Another reason why the fish had to eat the insects was because the insects threatened the loaches and eel seedlings, so they had to go out.

In the lotus pond, if you feel that the decontamination effect is not good, you can also raise crabs, soft-shelled turtles, such as crucian carp and the like, which can become food for soft-shelled turtles, and save feed for them.
