How to achieve zero growth and reduction of chemical fertilizer? How to break through the bottleneck of water resources in agriculture in arid areas? In recent years, through the implementation of the integration of water and fertilizer, Inner Mongolia took the lead in popularizing and applying new liquid fertilizer in the demonstration area of fertilizer control and efficiency, and summed up a set of practical methods in the field. This page welcomes contributions from all over the world to share the relevant experience of zero growth of chemical fertilizer.

"Boss, give me two buckets of fat. The wheat grown in my family is going to be watered soon. " Gao Laicheng, a farmer from Lianzeng Village, Hangjin Hou Banner, Bayannur City, Inner Mongolia Autonomous region, came to the gas station. Instead of refueling agricultural vehicles, he fertilized the wheat in the fields. According to Wei Yuhai, director of the Agricultural Technology Popularization Center of the Banner, this kind of fertilizer "gas station" is a key liquid fertilizer station promoted in the demonstration area of fertilizer control and efficiency in 2016, using a new type of liquid fertilizer instead of traditional solid fertilizer to achieve the integration of topdressing with water and water and fertilizer, so as to achieve the goal of controlling fertilizer and increasing efficiency.

Liquid fertilizer is a new type of water-soluble fertilizer, which can quickly and evenly mix with irrigation water. it can not only realize the integration of water and fertilizer through water-saving irrigation techniques such as sprinkler irrigation and drip irrigation, but also integrate with traditional irrigation methods such as furrow and border irrigation and fertilize with water. also achieve the effect of the integration of water and fertilizer, greatly improve the efficiency of water and fertilizer use, and increase crop yield. According to statistics, liquid fertilizers are widely used in developed countries. Liquid fertilizers account for more than half of nitrogen fertilizer consumption in the United States and more than 90 percent in Israel. In 2015, the output of urea ammonium nitrate solution in China has exceeded 400000 tons, refreshing the traditional pattern of nitrogen fertilizer production dominated by urea.

The income should be guaranteed and the demonstration should keep up.

"with this little fertilizer, can the crops grow well?" At the on-the-spot meeting on fertilizer control and efficiency in Inner Mongolia, visiting farmers had a lot of doubts about the application technology of liquid fertilizer recommended by technicians. Losing weight can also increase production, which is hard to believe for farmers who are used to flood and fat.

Liu Gen of Lianzeng Village is the first person to eat crabs with liquid fertilizer. As early as 2014, a technician from Hangjin Houqi Agricultural Technology Center tried liquid fertilizer for the first time in his wheat field, and the effect was so obvious that he spent his own money to buy liquid fertilizer in a town 10 kilometers away the following year. A liquid fertilizer station has been built in the village this year, and he is the most supportive. Why does Liu Gen insist on using liquid fertilizer? He got even with the author. Lianzeng Village is a Hetao irrigation area, which is used to grow wheat with great water and fertilizer, with 35 kg of base fertilizer per mu and 25 kg of urea per mu every year. In this way, 60 kilograms of chemical fertilizer will be invested in one mu of land, at a cost of 137 yuan, while after the application of liquid fertilizer, only 20 kilograms of base fertilizer per mu, 8 kilograms of urea ammonium nitrate solution and 2 kilograms of high potassium water-soluble fertilizer will be enough. in this way, the amount of fertilizer per mu is only 40 kg, at a cost of 130 yuan.

Liu Gen's application of liquid fertilizer not only reduced the use of 20 kg of chemical fertilizer per mu, but also saved 7 yuan of fertilizer money. the corresponding wheat yield per mu reached about 500 kg, which was nearly 40 kg higher than that of traditional fertilization habits, and calculated according to the wheat purchase price of 3.4 yuan per kilogram. 143 yuan per mu. "the use of liquid fertilizer can not only increase production and income, but also save worry and effort. It turned out that when we fertilized and spread urea all over the ground, especially when we planted corn, we had to drill into the ground, and our arms and faces were often scratched. Now, the work can be finished in two hours in the morning. " Liu Gen introduced the benefits of liquid fertilizer to me like a senior expert. In Lianzeng Village, there are many farmers like Liu Gen who actively accept new technology. While they are careful, they also simply believe in science. This year, the soil and fertilizer station in Inner Mongolia Autonomous region issued a sign of "demonstration households of science and technology for fertilizer control and efficiency" to these farmers, hoping that through their exemplary role, the whole society will pay attention to scientific fertilization and achieve zero growth in chemical fertilizer.

The variety should be improved and the technology should be matched.

The more and more chemical fertilizers are used, the harder the land is planted, and the output is stagnant, which is a common perplexity for farmers. "for a long time, farmers in Hetao Irrigation District have been accustomed to flood and fertilizer, and the promotion of liquid fertilizer can not be achieved without the support of supporting technology." Zhang Zhizhong, director of the Bayannur Agriculture and Animal Husbandry Technology extension Center, told the author that at present, the core contents of many agricultural technologies have matured, but the disconnection of supporting facilities has affected the overall technology promotion.

"We have focused on promoting liquid fertilizer for five years, and it has been lukewarm in the past few years. It was not until last year that we introduced self-service fattening machines and enriched the varieties of liquid fertilizer to meet the diversified needs of farmers." Liu Yujie of the Agricultural Technology extension Center of Hangjin Houqi said when he shared the experience of liquid fertilizer promotion with the author. In the past, the liquid fertilizer sold on the market is mainly urea ammonium nitrate solution, the packaging specification is unified, and the fertilizer price contains the packaging cost, which increases the planting cost. Last year, they cooperated with Sinochem to introduce a liquid fertilizer distribution system and a fattening machine, where farmers could bring their own containers to add fertilizer. At the same time, they also broke the packaging restrictions on the amount of fertilizer added, determined the amount of fertilizer added according to the plot area and crop varieties, and purchased fertilizer according to demand, thus realizing precision fertilization. Now there are more varieties in the fattening station, not only selling urea ammonium nitrate solution, but also a large number of element liquid fertilizer, organic liquid fertilizer and trace element liquid fertilizer for self-help choice.

According to the formula of fertilization, according to the guidance of farming.

Bai Yunlong, head of the Water Saving Section of the soil and Fertilizer Station of the autonomous region, said that relevant research on the application of liquid fertilizer in facility agriculture was carried out in Inner Mongolia in the 1980s, and it was widely used in facility agriculture around 2007. With the popularization of water and fertilizer integration technology for field crops, new liquid fertilizers such as urea ammonium nitrate solution and liquid compound fertilizer have been exploratory applied to potato, corn and other crops, especially in recent years, the state has encouraged large-scale agricultural management. the development of liquid fertilizer and new water-soluble fertilizer also began to speed up.

In order to guide farmers to choose and buy liquid fertilizer, local agrotechnical personnel have formulated guidance on fertilization for different crops according to the actual situation, from the period and amount of base fertilizer to topdressing, from a large number of elements to trace element fertilizer, etc., to provide farmers with set meal guidance.

"one kilogram more liquid fertilizer is applied, 100 kilograms of grain is added, and the total amount of chemical fertilizer has been reduced a lot. Do you think we can not believe other people's formula?" Liu Baosheng of Lianzeng Village said that in 2015, he planted corn in accordance with fertilization guidelines, applied 1 kilogram of fulvic acid chelated zinc fertilizer per mu of land, and beat more than 100 kilograms of corn per mu than others at harvest. Only 20 yuan more zinc fertilizer was invested, and the net income was increased by 140 yuan according to the purchase price of 1.6 yuan per kilogram of corn. Now, when he meets the farmers who learn from the classics, he says, "fertilize according to the formula and cultivate the land according to the instructions." (Li Xiaolong)
