"you can plant white flowers in alkaline land once a year. there are only a few seedlings, so if you don't harvest anything after autumn." you can often hear this jingle when walking in the fields of da'an city.
da'an city, located in the west of our province, is one of the three largest soda saline-alkali land distribution areas in the world. in da'an, saline-alkali land is distributed in 18 towns across the city, which once "stuck" the pulse of local agricultural development.
one day in september, the reporter walked into minle village, chagan town, and the scenery he saw was completely different from what the jingle said. in the crop fields of minle village, rice waves roll, and a golden picture appears in front of you. "the rain has been good this year, and our village can have a good harvest again!" li changjiang, secretary of the minle village party branch, said excitedly. according to li changjiang, in 2016, the land development and consolidation project implemented in minle village improved 17,000 acres of saline-alkali land into paddy fields. it achieved the design, construction, improvement, planting and harvesting of the same year. now the grain yield per mu exceeds 1,500 kilograms.
"at first, the villagers didn't believe that it could be improved. if this was not improved, wouldn't this year's work be in vain? the land would also be in vain." li changjiang said. in order to advance the project, the village cadres went to other villages with successful saline-alkali land improvement experience to learn about the situation. after seeing the golden color in the rice fields, they gradually felt confident.
"at that time, the village said that dry fields should be converted into paddy fields and rice should be planted. i was one of the first to oppose it. there are not even a few corns growing on this white-flowered saline-alkali land. can rice be grown?" said guo wanqi, a villager in his 70s. i have been dealing with the land all my life, and i never imagined that i could see the harvest scene of rice ears bending down. now, thanks to the improved saline-alkali land, the annual per capita income of villagers in minle village is more than twice what it was before the improvement.
"the improvement of saline-alkali land in da'an is characterized by using rice to control alkali." wang changzhi, deputy section chief of the soil improvement research section of the baicheng soda saline-alkali land management research institute, told reporters. in recent years, the western part of our province has implemented water conservancy projects such as river and lake connection projects, relying on natural river and lake water systems to build water conservancy projects. living water moistens all living things, and the connected water system brings abundant water. with living water, it is possible to popularize "treating alkali with rice".
dozens of kilometers away from minle village, in the planting base of zhongke baiao gelin agricultural development co., ltd. in haituo township, most of the rice has turned from emerald green to golden yellow. next to the rice fields, a high-erected display board showed: in the spring of 2016, this place was still a saline-alkali land with white flowers, and there were only scattered weeds on the surface.
meng xiandong, the person in charge of the company, said: "we started to improve it in 2016. after a series of procedures such as land preparation, application of amendments and organic fertilizers, we can now cultivate normally, and the yield is pretty good." the fields are gradually maturing rice, and the field ridge where the reporter was standing was still white saline land, with almost no grass growing on it. "the ph value of the soil here is as high as 9.5-11, the salt content is between 0.4% and 0.6%, and the alkalization degree is between 32% and 40%. without improvement, crops cannot grow." meng xiandong said with emotion.
so far, meng xiandong and his team have improved 118,900 acres of saline-alkali land, producing 900 to 1,000 kilograms of grain per mu, and high-yield plots can reach 1,100 kilograms.
carry out the "black soil granary" scientific and technological battle, promote the comprehensive utilization of reserve resources of cultivated land such as saline-alkali land, accelerate the improvement of grain production capacity, and turn more and more "barren lands" into "rice grain rivers".
in da'an city alone, since 2016, a series of ecological restoration and management measures have resulted in the creation of 127,300 acres of new cultivated land. this "white land" on the black land is turning green and golden, with waves of rice rising and waves of rice fragrance floating in the air.
