For the next seven days, Lu Chengcheng was busy planting sweet potato vines. By the seventh day, all the sweet potato vines were planted.

Lu Chengcheng then calculated the wages for everyone, and everyone went home satisfied.

Li Yun came to Lu Chengcheng and said, "Chengcheng, there's not much starch left. Remember to buy some next time."

starch?

Lu Chengcheng thought of the pile of kudzu roots in the yard. Now that nothing was to do, he could wash out the kudzu root starch.

Thinking of this, Lu Chengcheng returned to the old house, used a bucket to collect water from the faucet, and poured it on the kudzu root.

The surface of the kudzu root is dry and the mud is tightly attached to it. It needs to be soaked in water for a while before it can be cleaned.

A large vat is needed to wash the kudzu starch. Lu Chengcheng drove a tricycle to the pottery factory halfway up the mountain and bought five large pottery vats at a low price.

After buying the large ceramic jar, Lu Chengcheng went to buy a special machine for making mud. This machine can make mud from kudzu root, sweet potato, taro, etc.

Finally, you need to prepare a piece of gauze for filtering.

Tie the four corners of the gauze to a movable cross, and then fix the cross on a wooden frame. This wooden frame can just support the top of the pottery jar. After the kudzu root is beaten into mud, put the kudzu root mud in the gauze and filter it.

Water is needed during filtering. The water will drive the starch in the kudzu root to drip into the ceramic jar. After settling for a period of time, pour out the water on the surface, and what remains is the kudzu root starch.

This is what Lu Chengcheng saw in the video. Now she is starting to prepare according to the steps in the video.

Use a high-pressure water gun to rinse the kudzu roots one by one, wash them twice to prevent the mud and sand from affecting the taste. Then cut the kudzu roots into pieces with a knife and put them into the machine to make them into a paste.

Lu Chengcheng did not ask anyone for help, so Nie Haichuan helped her.

Mash all the kudzu roots into a paste.

The machine made a loud sound and many people came to watch.

Several grandmothers from the village simply watched the fun from the side. They had come to help, but Lu Chengcheng said that she was filming a video and couldn't ask for help, so they could only watch.

Lu Chengcheng brought them some food and drinks so that they could watch happily.

These grandmas helped her plant sweet potatoes some time ago. They have made great contributions and they deserve some food and drink.

After all the kudzu roots are beaten into mud, you can start filtering. Lu Chengcheng puts his hands on the cross and shakes it continuously. While shaking, the water in the kudzu roots will be filtered into the large ceramic jar below. Water also needs to be added twice while shaking, which is done by Nie Haichuan.

Nie Haichuan had never done such work before, and now he was drafted by Lu Chengcheng as a soldier, and he didn't know whether to laugh or cry.

But what amazed him was that he didn't feel tired at all after doing so much work.

Given his physical condition, he should be very tired.

Later he attributed this to the good air in the village, which improved his physical fitness.

One tank after another, finally the five large ceramic tanks were filled with filtered water, and the kudzu mud was finally filtered out.

At this point, there is one last step, which is to put all the filtered kudzu root paste together, add water and wash and filter it, which is to wash the powder for the second time.

After cleaning and filtering, the kudzu root mud was discarded. Lu Chengcheng buried it under the fruit trees to fertilize the trees.

Then let it settle overnight.

The next day, Lu Chengcheng came to the location where the five large ceramic jars were placed to observe the sedimentation situation.

The water is very clear, it should have settled well.

Nie Haichuan was very interested, so he came early in the morning: "How is it going?"

"It should be possible." Lu Chengcheng took the ladle and scooped up the water on the surface and threw it away.

It took me a long time to scoop out the kudzu root powder.

Nie Haichuan was obviously disappointed: "Is that all?"

Lu Chengcheng was also a little surprised: "It's a little bit small, I thought there would be a lot."

Scoop out all the water from the five large ceramic jars, then put all the kudzu root powder into a large ceramic jar, add water, stir well, and let it settle again.

This is the second sedimentation. If there is mud and sand, it will settle to the bottom.

Then let it sit for a day.

……

Lu Chengcheng grabbed a handful of melon seeds and ate them while walking towards the sweet potato field.

After half a month, all the sweet potato seedlings are alive and have grown vines that are more than ten centimeters long and are growing very fast.

Of course, the sweet potato vines grew, and the grass around them also grew, and it grew very tall. In short, it was time to weed. In addition to the grass, Lu Chengcheng also found a lot of Chinese grasshoppers.

This insect can fly and eats green leaves and sweet potato leaves. A few of them are fine, but if there are too many of them, it will become a pest. Some sweet potato leaves have been eaten with holes left by insects.

Lu Chengcheng frowned. Of course, pesticides cannot be used here. How can it be controlled?

Lu Chengcheng searched online for the natural enemies of the Chinese grasshopper, including birds, frogs and poultry. An ordinary chicken can catch and eat 50 to 70 locusts a day, and a duck can catch 100 to 150 locusts a day.

So should we keep some ducks here?

No, ducks are too destructive and this is dry land, and it's so hot they won't like being here.

So why not build a few bird's nest houses nearby, which can both raise bird's nests and prevent pests?

The swallow house at the old house is home to many white swallows and golden swiftlets. They have built more than 20 bird's nests, which looks pretty good.

Yes, it is easier to raise swallows.

Lu Chengcheng went to the village chief and asked him to help build six swallow houses next to the sweet potato field.

The village chief asked Lu Chengcheng if she was sure. When Lu Chengcheng said yes, he agreed to build it for her and immediately contacted help.

After this matter was implemented, Lu Chengcheng received three transfer messages on her mobile phone. One was a transfer of 200,000 yuan from the township entrepreneurship fund, 150,000 yuan from the youth entrepreneurship fund, and 100,000 yuan from the fresh graduate entrepreneurship fund. She received the highest level of support from each of them.

Firstly, her pig farm is indeed big, and secondly, the village cadres speak for her. She is the first young person to return to her hometown to start a business, and she must be encouraged.

In this way, Lu Chengcheng received a subsidy of 450,000 yuan.

Lu Chengcheng looked at the money and thought for a while, then prepared a bank card and transferred 100,000 yuan into it, to thank the village chief when the time comes.

Last month, Lu Chengcheng made nearly one million yuan from selling pigs. Now she didn't spend the one million yuan, but used it for investment.

The money I spend now is earned from selling loquats and vegetables. The loquats are sold out, but I can make 300 yuan a day from selling vegetables, which is relatively stable.

The video account can earn more than 2,000 yuan a day, which is relatively stable. Now there are a total of 120,000 yuan in the account, and she has not touched a penny.

She just asked everyone to help grow sweet potatoes, and the money from selling loquats has been spent. If there were no support funds, she would have to use the money in the video account, but now she doesn’t need to.

After get off work in the evening, Lu Chengcheng came to the village chief's house.
