Diaoli incense in saline -alkali land

About one -tenth of global saline -alkali land is in China, and about one tenth of Chinese saline -alkali land is expected to "return to life."

From Jilin Changchun to hundreds of kilometers northwest to a large white saline -alkali land, there was a nightmare of agriculture, droughts were knotted, and rainlords were waterlogging. But now, Baicheng, which is located here, has become the largest rice planting area in Jilin Province.

At four o'clock in the morning, the sky was just bright, and Ma Wei, an associate researcher at the Institute of Rice Research of the Jilin Academy of Agricultural Sciences, had already stepped down to observe the growth of rice and record various data. Eight years ago, he was only thirty years old when he first arrived at Gasheng Township, Zhenxian County.

Since 1988, the third -generation scientific researchers of the Jilin Academy of Agricultural Sciences have been working on saline -alkali land in Li County, Baicheng City. To achieve high yields, millions of acres of saline -alkali land in Zhenxian County can be developed and utilized.

The "baton" passed to Ma Wei is the third generation. The mission of this generation is to strengthen the local rice industry, making rice more fragrant and farmers' farmers.

Every year, Ma Wei will compare the production of dozens of new rice varieties selected by the unit, and then screen the high -quality, high -quality, and resistant new rice varieties suitable for planting suitable for planting in western regions of Jilin Province. But it is not a satisfactory result every year. In the first autumn, a strong wind blow down the rice in the test field. He paced back and forth in Tianyu, and it was difficult to sleep for more than a row.

Rice varieties generally will be updated for three to five years. Otherwise, not only will output decrease, but also decreases. In recent years, a number of high -quality rice varieties such as "Ji Juju 816" and "Ji Juju 830" successfully selected by Ma Wei and colleagues have been promoted in a large area in the western region of Jilin Province. Compared with traditional ordinary round rice rice, new varieties can increase their income of thousands of yuan per hectare of rice fields.

There are still a large amount of saline and alkali land in Zhenlian County. In order to screen the varieties of rice with stronger saline -tolerant as soon as possible, Ma Wei is trying to improve the screening efficiency. He tried to establish a set of rice salt -tolerant to a rapid screening evaluation system and the method of salt -alkali -tolerance for full fertility, providing a variety foundation for subsequent development of heavy saline -alkali land.

According to experts, in addition to the area of ​​1.9 billion mu of cultivated land, China has nearly 1.5 billion acres of saline -alkali land, accounting for about one -tenth of the global saline -alkali land, mainly distributed in the northwest, northeast, North China, and coastal areas. Among them, nearly one -tenth of saline and alkali land has the potential to develop and utilize. In the past few decades, countless scientific researchers have taken root in the grassroots level, and have made 10 million acres of saline -alkali land flourishing and endless.

This year, the water field area of ​​Zhenxian County reached 1.55 million mu. Ma Wei said that if China's saline and alkali land can be used reasonably, China's grain output will definitely go to a new level.

Recently, a newcomer came from the test station, and Ma Wei wanted to teach him his experience. However, some experience must be experienced to understand. He is brewing a "big plan" in his heart -writing a book, leaving many years of experience and passing.

"I also have to write down the family and discussing technology at the family of planting households at home. It is the happiest time of the year." Ma Wei said. (Finish)
