Change soil+change, Shandong saline -alkali land becomes "rice granary"

Recently, in the cure of salt -alkali and alkali in Dongying City, the high -standard farmland demonstration park has been cured by the cure of salt -alkali. In the fields of the improvement of the technical improvement of Shandong Qianshun Soil and Water Governance Technology Co., Ltd., corn and soybeans grow exactly. This heavy salt -alkali land, which was once deserted for 16 years, has now become a grain field with an average yield of 357.11 kilograms of wheat. "Before the improvement, the salt content was 16 ‰; after the improvement, it was reduced to about 3 ‰." Zhou Meiyan, a technician of the Agricultural and Rural Bureau of Kenli District, said.

"We use the sealing domain double -layer vacuum negative pressure resistance comprehensive technical system, use plastic membrane vertically to lay plastic, close the area to prevent the invasion of salt water, control the water level with the bottom layer, rinse the salt -alkali in the upper tube, the vacuum pump suction power is accelerated and penetrated, and the comparison has reached a comparison. Good transformation of the goal of saline and alkali land. "Said Gai Junshan, chairman of Shandong Qianshun Soil and Water Governance Technology Co., Ltd.

There are nearly 9 million acres of saline -alkali land in Shandong, and there are 3.418 million mu of Dongying City alone. It is one of the largest and most difficult use of Veteam -alkali -alkali land in my country and the world. %. How to fully tap the potential of saline -alkali land development and use, and ask saline -alkali land?

According to the current status and characteristics of saline -alkali cultivated land, our province adopts the "salt emission+supporting irrigation+land flat" engineering governance model, supplemented by soil improvement measures to improve saline -alkali land. Through the transformation, the Yellow River Delta saline -alkali cultivated land can plant 3.6 million acres of grain, 1 million acres of cotton, 1 million acres of jujube trees, and 100,000 acres of pasture.

It is not enough to "change the soil". The potential of the development and utilization of saline -alkali land needs to find breakthroughs from the root cause and "modify". "In the past, we used the method of digging deep trenches to increase the method of low salt and alkali, which is the land to adapt to the seeds. Now, we choose the seeds that are suitable for saline and alkali land to innovate in saline -alkali land." In the company's circulation, crickets, oats, barley, mandarine grass, sweet sorghum ... The largest test fields are arranged in order, the largest of which is the pilot field of rice. According to Zhou Hong, chairman of the company, the company introduced no less than 50 high -quality rice germplasm resources to the seeds every year through the cooperation with professional rice breeding institutions and college scientific research institutes at home and abroad to make trials and screening. And 3 high -quality rice varieties and 5 high -quality products and 5 high -quality products for large -scale industrialization.

Focus on promoting the technological innovation of saline -alkali cultivation industry, our province has strengthened the collection and utilization of seed resources, actively transformed the concept of breeding, and accumulated 24 new varieties (departments) of drought -resistant water -saving wheat, and 62 new varieties (departments) resistance of saline -bean -resistant soybeans (departments) 70 copies of saline -alkali rice resources, 6 new varieties (departments) of salt -alkali corn varieties (departments), and 5 new cotton varieties (departments) of moderate saline -alkali land. The selected "Qihuang 34" was planted in 3 ‰ saline -alkali land, and the yield per mu can reach 302.6 kg, which has achieved a new breakthrough in the yield of soybean saline -alkali land. High yield breakthrough on the land. The 37 medium -to -medium -altogenic grain and oil, pasture, and Chinese herbal medicines (departments) selected by the Yellow River Delta Agricultural High -tech Industry Demonstration Zone achieved 15%-20%of the acres of increased acres at the demonstration promotion base.

Technology enhances, and saline -alkali land transformed into a "rice granary". Our province has not stopped here. It also focuses on promoting the improvement of the quality and efficiency of saline and alkali land, and the benefits of the industrial chain to make saline -alkali land a "rich field".

There are large saline -alkali beaches in the north of Hansing District, Weifang City. In recent years, Shandong Binyuan Agricultural Technology Co., Ltd. has joined hands with academician Yuan Longping's sea and rice research and development team to promote the ecological improvement of saline -alkali land with seawood planting, and from the beginning that can only be sold at the beginning, to the industrial chain of the sea rice, becoming the only sea in the country Development zone of the integrated development of rice. Relying on sea rice, Binyuan Agriculture's turnover reached 230 million yuan last year, of which 60%-70%were two. With the larger production of the secondary production, the company's planning and construction of a 5,000 -square -meter food -level purification production workshop will be produced. In the future, it will produce a series of products such as rice and rice noodles and rice noodles through the new enzymatic and puffed processes independently developed by the enterprise.
