Until today, I realized that the black land stepped on when I was young, it was one of the only three ancient black soil on the earth and the only piece of China. I am fortunate to eat this land species of grain and vegetables.
Before liberation, there was called North Gate, and the black land of the large piece was ridiculous. Only the wild grass was crazy. When the War of Liberation, a large number of people came here to start the rules, and they were dug, they were black and sticky black soil, and some are a few meters thick. As long as they buried, they don't use manual to add fertilizers, and food is rich in yield. The waste has become a north of the North.
During the past few decades, when I first pushed, my grandfather will take me to the place. In my impression, it is a black oil, soft field, to the fall, is a wild golden wheat field. Polywherence.
After going to school, there is a tree planting activity every spring. At that time, the soil layer had just thawed. Some places were still hard, but they were very good, and the black black sticky soil had some cockroaches, and a large piece was sticky above. I can't get rid of it.
At the elementary school, we have a wide playground. After the annual summer vacation, we all have a full-scale labor, the most difficult job is to clear the weeds on the playground. People who haven't lived in such an environment may not be imagined, there is a green green in the playground, and some places also accumulate the water, and the seeds are very rich, and of course, all kinds of flowers are inevitable.
This is the memory of this black land to my childhood, accompanied by her aging, I have grown up.
The black land is indeed old. In the event of a generation, the rapid consumption of more than a million years, the nutrients accumulated in the year. The formation of a centimeter black soil is required for hundreds of years of nature accumulation, and now we can consume it only one year. Decades have passed, there are only 10 cm of black soil, even thinner. Below the black soil, like any barren place, is a yellow gravel, no matter how much fertilizer is placed, it is unable to plant crops, and the grass cannot be long.
When I was small, the field of the family was fertilized to use livestock, but I don't remember that year, I only need to put a few fertilizers. I can get harvest in the fall, and finally remove the fruits of the fruit. Pull it back, used for fuel in winter and life. Years of year, my elders are like this to cultivate on the land. We often compare the earth as a mother, yeah, she is so rich and selfless, raising us for thousands of years, as long as they cast seeds in the spring, spread their own sweat, never worry that she does not give us harvest. But even the most selfless mother will be aging, because we only ask her, never know that she needs to nourish.
We don't know how many years of fertilizers have made her skin hard. Al recently harvest fruits, but also plunder the crops of the crops that take the nutrients, we take everything to let her resist the barrier of the wind and rain. Ren to lose year by year.
If we don't nourish this black land now, after several years, when the aging mother can no longer bear this aging, her tears have been exhausted, and only dry faces.
