In Kung Fu, there is no panic in the event of drought and the follow-up investment needs to be solved.

Zhang Chunhai, a villager of Sanxing Village, Kailu County, Inner Mongolia Autonomous region, clearly remembers the rain in early May, when the dripping raindrops converged into a line, flowing into the cornfield that had just been sown, and into his heart. Zhang Chunhai calculated: in this way, don't worry about it this year, and the corn harvest must be good. The farmers were looking forward to favorable weather, but the drought came unexpectedly. "We haven't had a decent rain here in the three months since June 11." Zhang Chunhai said.

According to the statistics of the State General Administration of Prevention, since late June, especially after August, due to low precipitation and high temperatures, the drought began to spread in Northeast China, including Tongliao.

The development time of drought happens to be the key stage of the formation of autumn grain yield. Will the drought affect the harvest in the "big granaries" in the northeast?

Facilities construction should be consolidated.

Tongliao City has more than 20 million mu of arable land, and the grain output accounts for 1/4 of Inner Mongolia. It is one of the 23 prefecture-level cities with 10 billion jin of grain in China. In another month, the corn in Tongliao will enter the harvest period.

"it is true that there has been little rain during this period of time, but for us, it is nothing more than watering the land twice." Sun Lixin, a farmer in Liaoyang Village, Fengtian Town, Keerqin District, Tongliao City, said. The 3400 mu of arable land in Liaoyang Village has adequate irrigation facilities, of which more than 1000 mu have been used drip irrigation under plastic film this year. "as soon as you swipe your card in the well room, the water goes directly along the drip irrigation belt to the root of the corn." Sun Lixin said, "if the water is poured in time, it is expected that the output will not be affected much."

"the year of severe drought can ensure an overall bumper harvest, which is inseparable from the construction of irrigation and water conservancy infrastructure for many years." Li Jianguo, deputy director of Tongliao City Water Bureau, said. He recalled that the construction of irrigation and water conservancy facilities in Tongliao City began to accelerate after 2000, especially since 2011, water-saving irrigation facilities such as drip irrigation under plastic film and high-standard low-pressure pipe irrigation have been widely used. "at present, the irrigated area of groundwater in Tongliao reaches more than 10 million mu, which can guarantee the basic output of 10 billion jin of grain."

Of course, the drought is not completely unaffected. In the hilly area of Tongliao, where there is no water source, the drought has caused a disaster of 3.7 million mu of arable land. "fortunately, this year we have built 1.66 million mu of water-saving, high-yield and high-efficiency grain functional areas. The functional areas can increase production by 300 jin to 700 jin per mu, which can make up for the yield reduction caused by drought in some areas. With the general ledger, a bumper grain harvest should not be a problem. " Li Jianguo said.

"the fight against drought depends on accumulation in peacetime. Irrigation and water conservancy construction is in place, even if there is a drought, there will still be a bumper harvest. " Wang Hongjiang, deputy magistrate of Kailu County, said.

Agricultural water saving needs to be persisted.

Tongliao, which has been dry for a long time, is looking forward to a thorough rain. However, heavy rain can alleviate the temporary drought and can not change the fact that there is a long-term water shortage. "in the 1980s, Tongliao's large and small reservoirs were full of water." 'i can't remember when water resources became more and more scarce, 'Mr. Li said.

Statistics show that Tongliao has less than 1200 cubic meters of water resources per capita, making it one of the 110 cities with serious water shortage in the country. It is imperative to save water. According to one statistics, in 2012, Tongliao agricultural water consumption was 2.37 billion cubic meters, accounting for 83% of the total water consumption. Agriculture is the largest user of water, and agricultural water saving must go first.

The situation in Tongliao is not alone. In 2012, the Ministry of Water Resources and other departments jointly launched the action project of saving water and increasing grain in the four provinces and regions of Northeast China, with a planned investment of 38 billion yuan from 2012 to 2015 to build an area of 38 million mu of efficient water-saving irrigation projects such as drip irrigation under plastic mulch in the four provinces and regions of Northeast China. in order to improve the comprehensive grain production capacity and agricultural irrigation water use coefficient. Up to now, the Inner Mongolia Autonomous region has completed the task of building 4.51 million mu.

Small Nanjingwa Village, Kulun Banner, Tongliao City, is located in the hilly area. In the past, it basically depended on heaven for a living, and a good year resulted in a harvest of 500 jin of corn per mu. In 2012, Tongliao Water Bureau took the lead in implementing the drip irrigation project under plastic film here. "at first, people didn't believe that the ground could be watered through by dripping water with a thin pipe." Yang Jingxiang, secretary of the party branch of Little Nanjingwa Village, recalled that now, practice has dispelled everyone's doubts. "drip irrigation under plastic film takes only 15 cubic meters of water per mu, which saves water. As soon as the card is swiped, water and fertilizer are poured together to the roots of corn, and seven people can irrigate 5000 mu of land in 8 days, saving fertilizer and labor. "

Zhang Chunhai also felt the advantages mentioned by Yang Jingxiang. It's just that the Sanxing village where he is located is located in the plain, and the congenital condition is better than that of the small Nanjing WA village. "in the past, one mu of land could harvest 1600 to 1700 jin of corn, but now the use of water, electricity, fertilizer and labor has been significantly reduced, with an increase of more than 300 jin per mu of land." But Zhang Chunhai also has a small abacus in mind. Using drip irrigation under plastic film, each mu of land needs to invest about 200 yuan to replace plastic film and drip irrigation belt every year. "200 yuan investment for 300 yuan income, the investment is a bit high."

Follow-up investment to be solved

Zhang Chunhai's worries are exactly what Li Jianguo is worried about. "the state has implemented the project of saving water and increasing grain and invested a large amount of money. Well rooms, main pipes, etc. belong to one-time investment and can be used for a long time, but plastic film and drip irrigation belts need to be renewed year after year and put into long-term investment. "

The water-saving account of drip irrigation under plastic film is clear: 300 cubic water is needed to irrigate an mu of land in the traditional way, while only 120 cubic water is needed for drip irrigation under plastic film. But farmers have to calculate the economic account, how much income can the annual input of 200 yuan per mu of land bring?

"if, like Zhang Chunhai's family, the base of grain production is already relatively high, or in good weather years, the enthusiasm of farmers to invest will be reduced," says Li Jianguo, followed by the effect of water saving.

It is understood that there is widespread concern about the lack of follow-up investment in drip irrigation under plastic film. Li Jianguo said that he has discussed solutions with his counterparts everywhere more than once. "We hope that the relevant departments will formulate a stable input mechanism for water-saving irrigation, introduce preferential policies and compensation policies to encourage water conservation, and arouse farmers' enthusiasm for water conservation. At the same time, we also hope to use a reasonable water price formation mechanism to restrict extensive agricultural water use behavior. "

The long-term mechanism remains to be studied, and practical methods are already in practice. This year, an enterprise producing plastic film and drip irrigation belt was put into production in Tongliao, and the head of the company told Judong that they would trade in the used plastic film and drip irrigation belt to reduce the company's raw material costs on the one hand and farmers' input on the other.

Wang Hongjiang is trying to solve the problem from a different angle. "We have opened an experimental field in Wangjiadian Village to try out corn without film mulching and drip irrigation under the guidance of the scientific research department. if all aspects of the data are satisfactory, we will consider popularizing and reducing the investment in plastic film in the future." In the experimental field, the reporter saw corn planted with different varieties, different densities and different fertilizers. "We need to find the most suitable planting method for Kailu, increase the per unit yield from many angles, increase the income of farmers, and improve the input-output ratio of farming." Wang Hongjiang said.
