Weifang: In the past, saline -alkali wasteland is currently fertile wild gold

Qilu.com · Lightning News, September 22, there are 2.26 million mu of saline and alkali land in Weifang City, accounting for about 1/4 of the province. In recent years, Weifang City has efficiently promoted the comprehensive governance of saline -alkali and land, forming a new model of combining agriculture and animal husbandry, breeding, and multi -functional comprehensive governance, which has launched a new road for the comprehensive governance of saline -alkali and land in the country.

In Qingfu Village, Liuyi Town, Changyi City, the 25,000 acres of corn of grain, Sun De Dong, growing up. It is hard to imagine that this green crops are all saline -alkali land of white flowers. Until a few years ago, there was a high degree of saline and alkali.

Sun Dadong told reporters that the salt content of this land can reach more than 10 ‰, but now it is not reached by 2 ‰. Looking at the growth of the corn, it is no problem to produce more than 1,000 pounds per mu this year.

How does seeds grow corn on saline -alkali land to achieve high yield? It turned out that the corn here grew up drinking fresh water. The top 51.4 kilometers of irrigation and pipelines that are deeply buried underground constantly drawn the Water River water from 17 kilometers away for freshwater compression. "Dreatment of water storage, extracting brine, deep water, freshwater pressure alkali, crop suction, and cultivation of good varieties" Six -step methods of saline -alkali land improvement.

Xu Guangliang, a agricultural technology staff member of Liuyi Town, Changyi City, said that they planted cotton in the first three years in saline -alkali land, cotton in the fourth and fifth year, and planting grain crops such as wheat corn in the sixth year. The pattern can effectively reduce the saline and alkali content in the soil and ensure the output of food.

At the same time, in the development demonstration zone of the integrated development of seawa -rice production in Hansing District, Weifang City, Shandong Binyuan Agricultural Technology Co., Ltd. cooperated with Academician Yuan Longping's team to adopt the four -dimensional improvement method. The irrigation system and the integrated system of water and fertilizer improve the soil. In the past, the deserted saline -alkali land, now the symbiosis of fish and shrimp and the rice flowers are fragrant.

Meng Yang, the executive director of Shandong Binyuan Agricultural Technology Co., Ltd., pointed to an electronic equipment in a rice field and told reporters that a sensor was installed in each rice field. Real -time data transmission was performed through the sensor with the Internet of Things system and the big data platform center. Data analysis of the salinity of rice fields and its drought degree. If the degree of saline and alkali is too high, the dark tube salt discharge system will be enabled for salt. If the rice fields are relatively dry, the smart irrigation system is used for irrigation to achieve the ideal of rice to achieve the ideal of rice. Planting environment.

According to reports, in 2021, the average yield per mu of seawater reached 691 kilograms, and the food output per mu was doubled. Relying on the planting of sea rice, more than 70 species of derivatives such as condiments, rice noodles, and rice cakes are also developed locally, adding added value. This year, the area of ​​seawater planting in Hansing District, Weifang City, has increased to 58,000 mu. It is expected to achieve a grain output of 37,000 tons, and the output value is about 230 million yuan.

At the same time as the grain is full, in the Binhai District of Weifang, Shengwei Group re -recover the soil relying on the patented technology system. After the rehabilitation, it adheres to the seed industry innovation. A new and high -efficiency agricultural path that combines first, second, and tertiary industries and ecological cycle sustainable development of "species, maintenance, and addition" on saline -alkali land.

Yuan Yong, the research and development manager of Shengwei Group's production technology center, said that there are four agricultural industrial methods: pastoral planting, fruit forest planting, beef beef breeding, and milk sheep breeding in the park. In the middle of the operation, the plantation of pastoral grass will be fed, and the cattle and sheep, cattle and sheep, cattle and sheep, cattle and sheep, cattle and sheep The dirty manure generated by the farming is processed by the organic fertilizer plant, and then returned to the fields to cultivate the fruit forest land and pastoral land to form a complementary industrial ecological cycle model.

Today, through comprehensive governance, the saline -alkali beach in Weifang not only becomes granary, pasture, garden, but also orchard, green space and scenic spots, seawater series products, alkaline land and cattle, ganglide Chinese medicine, Cistanche, "coastal red" apples and other well -known groups such as apples and other well -known apples Featured agricultural products brands are becoming a carrier that help farmers increase their income, accelerate rural revitalization, and achieve common prosperity. In the past, saline and alkali land became today's "cornucopia".

Li Xiuming, deputy director of the Promotion Office of the Weifang National Agricultural Comprehensive Zone, said that Weifang City will continue to adhere to scientific and technological innovation, focus on industrial integration, continue to closely related to saline -alkali ecological agriculture, and explore new new varieties such as black cows, Fangqing roses, Qingfu agriculture and other new varieties and new varieties.Models make contributions to ecological restoration and protection of food security and create a model of agricultural zone.
