We will ensure that the red line of 1.8 billion hectares of cultivated land is maintained, and fully develop and utilize 500 million hectares of saline-alkali land.If saline-alkali tolerant crops are developed, they will play an important role in ensuring China’s granary and rice bowl.On the afternoon of October 22, 2021, Xi presided over a symposium on Promoting Ecological protection and High-quality development of the Yellow River Basin in Jinan, Shandong Province, and delivered an important speech.President Xi Jinping looks at the growth of soybeans while visiting the Yellow River Delta Agricultural high-tech Industry demonstration zone in Dongying city, East China’s Shandong Province, Thursday morning before a symposium.Spring ploughing is approaching, luo Shouyu arrived early in the morning to prepare agricultural materials in the Yellow River Delta Agricultural High-tech Industry demonstration zone in Dongying city, Shandong Province.”This is where the general Secretary walked to the fields that day,” he told reporters, pointing to a display board.On October 21, 2021, General Secretary Xi Jinping visited the Yellow River Delta Agricultural High-tech Industry Demonstration zone for investigation.”The red line of 1.8 billion mu of cultivated land should be maintained, and 500 million mu of saline-alkali land should be fully developed and utilized.If saline-alkali tolerant crops are developed, they will play an important role in safeguarding China’s granaries and rice bowls.”In the spring of the Year of the Tiger, the yellow Triangle agricultural high area is working hard to build a “new granary”.”I’ve been planting all my life, how can anyone be so happy now?” Luo Shouyu said happily when they got into the warehouse and picked up a handful of soybeans. “The general secretary of the Communist Party of China said all the beans we plant here are good.”On the day of General Secretary Xi Jinping’s inspection and investigation, Luo Shouyu, as the head of the Technology Innovation Center for comprehensive utilization of saline-alkali land in the Rural High Area of the Yellow Triangle, made an introduction at the scene.The general secretary went into the field, bent down, picked a pod, peeled a bean, chewed it in his mouth and said, “Beans grow very well.””We are very excited by the general secretary’s affirmation.”He took the reporter to a field and said, “On October 26 last year, five days after the general Secretary arrived, beans were harvested in this saline-alkali field. The yield per mu reached 470 jin, a new high.”Good news spread throughout the once barren land.At the soybean packing point in nonggao district, “old guard” Chang Xiuzhi hummed a tune, shaking open a dustpan, each golden soybean jumped up.”If you look at the beans, they are round, and you can’t find many flat ones.In the past, the white salt and alkali flats yielded 300 jin per mu of land.”Chang xiuzhi sighed, “After a lifetime of farming, how can it be so delightful!”The granary is full of joy, the field of hope.The wheat seedlings are green and swaying in the wind in the modern agricultural experiment and demonstration base of saline-alkali land in the agricultural high area.Demonstration base technician Li Ruitian squatted down, cleared the wheat seedling root soil, immersed in the look: “not bad!He’s four or five centimetres high. He’s looking good.”He pushed the soil back, grinning a joy, “Spring back warm, everyone shooting up.”As China’s second state-level agro-high area, the Yellow Triangle agro-high Area was established in 2015 with a total area of 350 square kilometers. Due to seawater invasion and other factors, more than 80% of the area is saline-alkali land.”Look, ‘gold bumps’ are growing on the saline-alkali land!”Luo Shouyu stood in front of the panel that Xi had seen, calling the names one by one: soybeans, black wheat, quinoa, potatoes…Through ecological utilization and seed industry innovation, salt-tolerant grain and oil crops with high yield and good varieties, as well as salt-tolerant herbage and Chinese herbal medicine have grown in salt-alkali land.”Let’s go!Chen Haihua, a senior engineer at the Institute of Computer Science of the Chinese Academy of Sciences, gave an order on the intelligent agricultural machinery platform in the rural high school district, and four unmanned “Big Iron Cattle” were lined up and headed straight for thousands of mu of alfalfa fields.”These big guys have a point.”Chen haihua walked out of the control room and came to an iron ox parked in a field. Patting its silvery white arched body, he said, “It is called honghu and we have recently developed it with new energy, Beidou navigation satellite and remote control as its keys.”Chen Haihua told reporters that alfalfa is known as “the king of grass” and can harvest four crops a year here.The “big guys” could harvest the 1,500 mu of land in less than two days.From human to mechanical ploughing, from experience to the use of data, agriculture inserted the wings of science and technology.According to statistics, the contribution rate of agricultural scientific and technological progress in China has exceeded 60 percent, and the overall mechanization rate of crop cultivation and harvesting has exceeded 70 percent.”Let more characteristic soybean products on the common people’s table” in the Yellow Triangle agricultural high area, reporters often hear such words: “domestic saline-alkali plant excellent varieties more up!”‘It’s more fun to farm!”The general Secretary stressed the need to change the concept of breeding, from treating saline-alkali land adapted crops to breeding saline-alkali tolerant plants adapted to saline-alkali land.”Luo Shouyu opened the little book he carried with him, and the above lines were full of strength: 7 breeding platforms have been built, 5 experimental platforms have been built, 7 germplasm resource nurseries have been built, and a number of breeding talents have been introduced…”Di, di, di –” at the breeding platform in the agricultural high area, the blue control cabinet sounded an alarm, and Engineer Lin Shuangbu of the Institute of Botany of the Chinese Academy of Sciences rushed to check.”The level is below 13 centimeters. It’s time to add nutrient solution.”Lin shuang clicked the screen several times, looked up to the cultivation room, less than a minute, nutrient liquid “purr purr” from under the cultivation frame out.”Quinoa, soybeans, sweet sorghum, alfalfa and ryegrass are all new varieties of saline-tolerant plants.”Lin Shuang pointed to rows of cultivation rack, “the ans planted crops in the nutrient solution cultivation tank, accurate supply of nutrients, can greatly shorten the crop growth cycle, to achieve ‘rapid breeding’.”Come out from breeding platform, reporter meets zhao Bo of footstep in a hurry.He is a technician of Dongying Yandi Quinoa Seed Industry Technology Co., LTD., and spends all day in the greenhouse platform.Reporters with him into the greenhouse ho!Red, orange, yellow, green, blue, purple, a blaze of color.”Pretty?You look first!”Leave a word, Zhao Bo went straight to the ground, picked up scissors to cut off a quinoa, shelf ruler, photograph, measurement, record at one go.After finishing the work in hand, Zhao Bo introduced, “This is the next step of laboratory breeding.Quinoa is ripe these days, so we have to harvest it fast and record the data.At present, the cultivar has reached the expectation, and the yield is expected to achieve 500 jin per mu.”One after another new varieties of saline-alkali tolerant plants were born in the rural high area: the yield of potato new varieties per mu reached 4413 kg, alfalfa hay 595.4 kg, sweet sorghum fresh weight 5288.7 kg, black wheat 600 kg……”The general secretary is concerned about saline-tolerant plant breeding and promotion, and we are making efforts in this direction.”Jin Zhendong, general manager of Dongying Zhongtian Agricultural Technology Development Co., LTD., said he is interested in the soybean varieties developed in nonggao district, which are not only grown locally but also spread to Hebei, Henan, Anhui and Hubei provinces, with a total planting area of about 35,000 mu.”Adversity makes good taste!This year, in addition to continuing large-scale planting, we are also preparing to build a processing base, hoping to let more characteristic soybean products on the table of the people.”Seeds are the “chip” of agriculture, and cultivated land is the “lifeblood” of food production.”It’s a very odd place to talk about.Blame in three words: ‘alkali’ ‘plate’ ‘thin’.What was it like?The ground was bare and covered with white wool.Dry bang hard, like a brick hit a nail.Soil fertility is low, there is no crop.”Li Ruitian has been dealing with this land for more than ten years, “and now it has changed itself into fertile land.Ecological utilization is very important, water saving, salt control and fertilizer cultivation are the key.”It was windy recently, so he had to put some soil on the micro-spray so it wouldn’t blow away.Field strips of black micro spray belt quite spectacular, a careful look, with the eye of a needle like water holes.”When the water is watered in spring, when the valve is opened and the water mist comes out, these ‘seedling babies’ open their mouths to suck in water.”Li Ruitian said.The biggest problem in the Yellow River basin is its fragile ecology.”When the general secretary came to inspect and investigate, he stressed that ‘there is as much soup as there is bread’.This is agriculture to save water ah.”Li Ruitian led reporters to see the ditch beside the ridge, “in the past deep ditch river, large water pressure salt, high cost, ecological disturbance;Now precise drip irrigation, small ditch connected, micro-spray belt, drip irrigation and other water-saving equipment spread all over the ground, both salt control and water saving.”Water is so expensive, can you be more careful calculations?Wang Guangmei, director of the Yellow Triangle Saline-alkali Land Agriculture Station in yantai Coastal Zone Research Institute of the Chinese Academy of Sciences, has not been less concerned about this question.He and his workers lay new drip irrigation pipes in a test field.”Ready for brackish water irrigation.””Through field experiments, we can find the upper limit of salinity that crops can tolerate at each growth stage, and then rationally irrigate brackish water to realize efficient water utilization and save more than 30 percent of fresh water in three years,” Wang said.A crop flower, all rely on fat alone.”We should keep in mind what the General Secretary has said and follow the path of green agricultural development.”In the agricultural high area of Chinese Academy of Sciences biological industry technology pilot research and development platform, research and development staff Yue Guolei picked up a bottle of microbial agent sample bottle shook, “the microbial agent we developed, green and pollution-free, but also can effectively improve the soil, reduce the amount of fertilizer.”Platform workshop machine roar, assembly line running at high speed, feeding, constant volume, stirring, fermentation……After 72 hours, the finished microbial agent will be released from the fermenter into the automatic packaging line.”Now the soil is soft and fine.”Li Ruitian picked up a lump of earth, put it in the palm of his hand gently grip, fine soil down the fingers, “in the past three years, the agricultural high area of the soil has improved 1 to 2 levels.””Now that the land is better, I can harvest more grain!”Li Ruitian laughed at the green black wheat in the field.Walking into the Yellow River Delta Agricultural High-tech Industry Demonstration Zone in Shandong Province — “Gold bumps
