"Then we will stay here for seven days?" Lamei asked.
"No, in the past seven days we have collected some horse dung, pig dung, cattle and sheep, chicken, duck, goose and dog dung in the fields, villages and various places." Bai Haitang said.
"What do you want those for? It's too late for others to throw them away." Lamei asked.
"We need to make compound fertilizer." Bai Haitang said.
"What is compound fertilizer?" Wintersweet looked innocent.
"It's something that can make other people's bankers in our land have more." Bai Haitang explained. Lamei nodded in understanding. Anyway, just do whatever Sister Haitang asked you to do.
For the next seven days, the two pulled the sledge and picked up a lot of excrement from various domestic animals. Finally, it was mixed with human excrement, turned into dung water, and poured into the ground bit by bit.
In addition, there is another thing mixed in the dung water, that is, plant ash. The humus of the plant ash, especially the plant ash made from various dried leaves on the mountain, is more valuable.
I looked at the limestone once a day and felt relieved when I saw that the fire was still burning. On the seventh day, the fire was extinguished and the limestone turned into lime, which was in the form of gray-white powder.
Bai Haitang and Lamei packed these, and they carried the packages into the ground together, and then spread them into the ground layer by layer.
The brother-in-law and sister-in-law were assigned by their mother-in-law to sometimes secretly go to the fields to observe what Bai Haitang was doing, but they really couldn't understand what Bai Haitang was doing.
The banker's land has almost been dealt with. Bai Haitang doesn't want to spend all her time on it. The land is just the beginning for her. In the era of agricultural economy, she wants to develop handicrafts. I will also turn this village into a dyeing workshop. If I am destined to never go back
, then I will dye a colorful pastoral!
Go back. A thought flashed through Bai Haitang's mind. He traveled back in time because he was playing with the ancient jade cicada, so the way back must be like the jade cicada. If he can find it in this era, the way home will not be far.
Already.
Every household here wears clothes of numb primary colors. If they were dyed in colorful colors, Bai Haitang believed that they would be popular. Sitting on the edge of the crop field and looking at the various wild flowers inhabiting them, Bai Haitang smiled. Those are the dyes of the future.
She knows that dyeing must first mix the five major colors of green, yellow, red, white and black, and then use them to blend the intermediate colors.
Cyan is mainly dyed with indigo extracted from indigo grass, because Xunzi said, "Green is derived from blue, and green is better than blue." Epiphytic indigo grass is easy to grow in the corn field, and the white begonias are picked quickly.
There are several plants.
It is also mentioned in the great book "Tiangong Kaiwu" that "all five kinds of blue can be made into indigo", which means that indigo can be made from polygonum indigo, horse indigo, wood indigo, amaranth indigo and so on.
Dye can be extracted from blue plants and flowers that are easy to color.
As for red, Bai Haitang immediately thought of the mine where hematite iron powder could be extracted.
For yellow, you can use gardenia fruits and locust flowers. For black, you can use persimmon leaves, gallnuts, sage leaves, chestnut shells, etc. There are more options.
Bai Haitang's mind was a little overwhelmed. This was the first time that he recalled the knowledge he had learned so deeply, and almost all these plants could be found in this countryside.
There is another reason for Bai Haitang's enthusiasm, and that is her major. Chemistry is almost useless in modern times, and it is difficult to find a job. Especially for girls majoring in chemistry, almost no one wants it.
Now, in this small village, she has a chance to show off her talent.
