[Explanation] October is the autumn harvest season in Northeast China.
In Zhenlai County, Baicheng City, in the western part of Jilin Province, a large area of saline-alkali land has ushered in a bumper harvest this year. Large-scale agricultural machinery is operating in the paddy fields, and the golden ears of rice are harvested and bundled.
Recently, the reporter and rice expert Ma Wei came to Gashigen Township, Zhenlai County, and randomly took soil for measurement. The soil pH value was weakly alkaline.
This is an amazing achievement.
In the past, the moderate to severe saline-alkali soil and the frequent flooding of the Nenjiang River often caused poor or no harvests here.
The Baicheng area used to be known as the "Eight Hundred Miles of the Sea" because of its long-term salinity and drought, and agricultural production was very limited.
Today, this barren land has become a big granary in Jilin Province.
This change is closely related to the garrison of agricultural science and technology personnel. Using rice to "conquer" saline-alkali land is a special method here.
Ma Wei, an associate researcher at the Rice Research Institute of the Jilin Academy of Agricultural Sciences, and three generations of rice experts from the institute witnessed that Gashigen Township became the first township of paddy fields in Jilin Province (280,000 mu), and Zhenlai County became the first county of paddy fields in Jilin Province (1.55 million acres). mu), and Baicheng City became the first rice city in Jilin Province (3.37 million mu).

Every generation of experts he has his mission.
The first generation of experts realized a change from no paddy field to one with paddy fields in Zhenlai County, and the second generation of experts realized a transition from low-yield, relatively low yield to high-yield in Zhenlai County in saline-alkali land, and the third generation of our current goal is to increase with the standard of living. With the improvement, people's demand for high-quality rice is also increasing. The mission of our third generation is how to change from high-yield to high-quality rice.
[Explanation] In the past, the vast land was cracked due to drought, and the soil showed a gray color because it was too alkaline.
Achieving a bumper harvest is the wish of every farmer and scientific and technological worker, for which they need to overcome many difficulties.
Seeds are the "chips" of agriculture and the foundation to ensure national food security.
Ma Wei said that at present, he is working hard to establish a rapid screening and evaluation system for rice salt tolerance and an identification method for salt tolerance throughout the growth period, so as to screen out rice varieties with stronger salt and alkali tolerance more quickly.

Because I have also screened out some relatively salt-alkali-tolerant varieties and some high-quality food varieties this year, we will conduct a small-scale demonstration next year, and next year we will also come up with some overall sorting out of the cultivation techniques of saline-alkali land. The first one It is to make the key technologies of saline-alkali land, such as the selection of varieties, the management of cultivation techniques, and how to improve these technologies in saline-alkali land. The first is to make them practical, so that the common people can understand and love to see them, and display them in the form of pictures.
[Commentary] Ma Wei said that now the fourth generation of agricultural workers has been stationed in the local area, and passing on valuable experience is another important work of Ma Wei.
Looking around, the "Hanhai" has become a fertile field and is driving farmers to a prosperous life.
Relying on the improved soil, Zhenlai County is becoming a new granary of Jilin Province.

Since the late 1980s, Zhenlai County has developed the rice industry through "treatment of alkali with rice" and "treatment of waterlogging with rice". Up to now, the area of rice in the county has grown to 1.55 million mu. , is now the largest county of paddy fields in Jilin Province, with an annual output of about 2 billion catties of rice. It has now become a rich industry for the masses and the leading industry of agriculture in our county.
