Welcome to the 20th 丨 Yellow River water, how to achieve "a drop of no waste"

On the occasion of the Chinese Farmers' Harvest Festival, the Wo Wild Wild Wild Wo Wo is golden along the citizens of the citizens of the citizens.

"The yield of glutinous corn is expected to be more than 800 kilograms, and the average yield of wheat is 670 kilograms. This year, it is expected to achieve the" ton half grain "creation goal." He Shibao, the planting manager of the dark plain land Luwang Agricultural Development Co., Ltd.

The harvest of autumn grains can be expected, and summer grain is added. What is even more valuable is that agricultural production does not increase water. Texas this year's annual routine yellow yellow yellow yellowing cubic meters, a decrease of 140 million cubic meters from the previous year; in recent years, it only accounts for only 4.3%of the water resources in the province. 8.2%of cultivated land produced 17%of the province's grain.

Shandong's per capita water resources are less than 1/6 of the country, and tighten the "faucet" of agricultural with a total of 60 % of the total water, which is of great significance for resource -based water shortage and engineering. Texas is the first prefecture -level city in the country to "over -produce a ton of grain and total output exceeding 10 billion yuan". It is currently striving to create the first large -scale "tons of half grain" demonstration zone in the country. The "water -saving Jing", which is responsible for grain safety, must also be read well. Recently, the reporter walked into the fields of Ningjin County, Yucheng, Pingyuan County, Qihe County in Ningjin County, Texas City, exploring the implementation of the major national strategic implementation of the Yellow River, and a new concept, new practices, and new changes in deep water -saving and water -controlling battles.

Water rights to households and measurement according to squares, one year of water saving is equivalent to two years of living water in the county

The average annual water saving of water per mu is 25 cubic meters, and the average annual water saving of the agricultural water saving is 20 million cubic meters.

These changes point to a comprehensive reform of agricultural water prices to Ningjin County in the province.

Ningjin, located at the junction of Jilu, is a yellow end of Texas. The per capita water resources are only 1/6 of the province. Agricultural irrigation is mainly well irrigation. Still relying on the Yellow River water supply.

"It turned out that the water was poured in the sky, and there were more than 70 cubic meters of water in one acre of water." On September 9th, Wang Meng, a large number of grains in Liu Yingwu Township, Ningjin County. Irrigation needs, but due to unwavering water, the new water well had to be 6 meters in the past few years. The water level decreased, and the water quality became worse -micro -salt water was significantly more obvious than before.

On the one hand, the rigid constraints of the yellow indicators are getting stronger and stronger, and on the other hand, it is listed as a pilot of comprehensive governance of the national groundwater hyper -mining area.

Since 2016, Ningjin launched a comprehensive reform of agricultural water prices, and the 150 million cubic meters of water used by agriculture as the initial water rights, allocated to various towns and villages, confirmed the right to the household, issued a certificate to the village, and the water rights were visible and touched. Requesting, transferable, and supporting mechanisms such as ultra -quota accumulated price increase and water saving rewards; in the fields of 750,000 acres of valid irrigation, installation of dual -control equipment of hydropower, pumping station ultrasonic flow meter, etc. Tolls.

The regulation of price leverage is the most effective and direct. "Use more money and spend less money. Everyone wants to save water." Wang Meng said that last year, 1,000 acres of land received 5,000 yuan of water saving rewards.

Give full play to the role of the price mechanism to force the effect of water saving. Gong Yongbo, a second -level investigator of the Rural Water Conservancy Department of the Provincial Water Resources Department, said that the province has accelerated the establishment of a new agricultural water mechanism for the establishment of "preferential water prices in the fixed amount of water and water prices for overflowing water", and has accumulated a total of 64.4 million mu of agricultural water prices. Essence

The new mechanism is effective, and the level of fine management is very important. The Xinzhai Town of Yucheng established the Farmers Water Association to clarify the pumping station property rights association. Chairman of the Water Association, Wen Fuxing, Secretary of the Party Branch of Wenzhuang Village, took out a portable mobile water meter and said: "Watering in the village, applying for an open pump station in the association, and the water to the ground, the administrator uses this 'guy' accurately measure, charges according to square fees, and charges according to square fees. ","

According to statistics, the Yellow City Yellow Yellow cubic meters was 85 million cubic meters last year, a decrease of 15 million cubic meters from the previous year.

Move your fingers, "feed water" accurately, and "quench thirst" for half an hour of crops for one acre

In the autumn season, a large pointer spray irrigation machine stands in the corn field of Luwang Farm, Taoyuan Street, Pingyuan County.

Since 2019, the Luswang Company of Plain Land has traded 20,000 acres of land, developed high -quality and efficient agriculture, and hired a number of college students to manage. The post -90s master He Shibao was responsible for technical guidance.

"Before the circulation, this area is generally large water irrigation, and sometimes it can't be poured for a month. Missing the water diversion time, the farmland is facing the dilemma of no water 'drink". "He Shibao said that in order to solve the problem of watering, the company purchased 16 Clear pointer spray irrigation machine. "This kind of spray and irrigation raised 500-600 meters, one can cover up to nearly 500 acres of land."

Increased efficiency and obvious water saving. "Nine comprehensive meteorological stations are evenly distributed in the fields, and the soil is dynamically monitoring the soil in real time. Time, the device can automatically water. "One acre of land is irrigated, and water requires sixty or seventy square meters. Now simulation of 20 mm precipitation, less than 20 square meters of water is enough." Luwang Farm is 50 kilometers south, and 1.2 million acres of "tons of grain" in Texas. Qihe County, one of the core areas, and Jiaomiao Town, Qihe County, and the Provincial Academy of Agricultural Sciences and Shandong Qilixin Agricultural Service Co., Ltd. are experimenting with the new water -saving technology of "water from underground" in Zhouzhuang Village. In 200 acres of grain fields, dense underground seepage irrigation equipment was buried at 30-40 cm from the ground surface.

Watering per acre for 17 minutes, 8 cm in the upper penetration, watering for 11 minutes, and 5 cm in the upper seepage ... Li Jianguo, the director of the planning of Jiao Temple in Jiao Temple in Qili, showed reporters to reporters the test data recorded not long ago. "The water is accurate to the root of the crop, and the average time of the acre is about half an hour, and the ideal effect will be achieved, and it takes two hours to fill the water."

This year, Qihe County's high -efficiency water -saving irrigation area reached 868,900 mu, accounting for 82.82%of the effective irrigation area. Compared with the large water irrigation, the annual water saving is about 50 cubic meters per mu, and the annual water -saving amount is more than 43 million cubic meters, which is equivalent to 36 Daming Lakes.

According to the relevant person in charge of the Provincial Agricultural and Rural Department, Shandong supports new agricultural business entities to use advanced irrigation technologies such as spray irrigation and drip irrigation, and develop high -efficiency water saving irrigation in high standard farmland construction. As of this spring, Texas has established a total of nearly 6.84 million acres of high -standard farmland, accounting for about 70 % of the city's arable land.

Water is used to use, and it will stop if you finish it.

The summer flood season ended, and the gate was released on September 9. Li Zhaomin, director of the Yellow Gart Management Institute of the Texas River River, who has worked on the bank of the Yellow River for more than 30 years, watched the rolling Yellow River winding north every day and flowed to 8 counties (cities, districts) in Texas.

"The gate flow of the gate is 34 cubic meters per second, and the water meter of the Yellow River is getting more and more fine." Li Zhaomin said that the Yellow River is the most important customer water resources in Shandong. To protect the ecological development of the mother's river, the contradiction between the supply and demand of yellowing and demand is not wasted.

Dry canal is the "aorta" of water diversion and the "key ring" of water -saving. As the head of Texas Drive, there are 4 yellow gates in Qihe, forming two large irrigation districts of Panzhuang and Li Jia'an, and two medium -sized canals in Han Liu and Tofu Nest. Han Liu Qianqu flows through 4 towns in Qihe. In the past, when the Yellow River water came, the upstream "fat water does not flow outsiders fields", raising the water level by itself, so that the water should flow as much as possible to its own canal.

Sun Yifang, the head of the Water Conservancy Station of Hu Guantun Town, said that most of the gang and the canal did not control the gates. The water was put on the upstream. "".

Li Shouxue, director of the Texas Water Resources Bureau, introduced that with the help of the national cither Yellow irrigation district continuous construction and water -saving reconstruction project, the province's agricultural water -saving project in the province's yellow irrigation district, began in 2020, Texas to rectify agricultural water project facilities in Texas The reconstruction and maintenance of buildings such as slope lining and bridge gates. Han Liu Qianqu and the village branch can install all the water -saving sluice, intelligent measurement and control terminals. As soon as the amount of water is used, the water -saving sluice is closed immediately.

Kongguan Village, Hu Guantun Town is located in the upper reaches of the dry canal. The village party branch secretary Manfeng Ying said that in the spring of this year, the village was more than 2,000 acres of land, and it was poured in less than 10 days.

Han Liu Qianqu used 20 million cubic meters of water a year, lined with the slopes of the bottom, and 2 million cubic meters of water a year. In addition to restraint measures, the effective irrigation area has increased from 89,000 mu to 150,000 acres. Looking at the province, Shandong has invested 21.3 billion yuan in the past two years. It has completed 65 agricultural water -saving projects in 65 citations. The effective irrigation area of ​​farmland has increased from 77.42 million mu in 2016 to about 80 million mu in 2021, and agricultural water The amount decreased by 760 million cubic meters during the same period.

Strengthening the use of intensive use of water resources is a hard task to implement the major national strategy of the Yellow River. "Shandong insists on the" Four Water and Four Ding ", implement the strictest water resources protection and utilization system, and fight in depth water saving and water control." Liu Zhonghui, director of the Provincial Department of Water Resources, said that Shandong last year's agricultural irrigation water effective utilization coefficient reached 0.6472, compared to compared with The average level of the country is about 8 percentage points higher; in order to account for about 1%of the country's freshwater resources, it has irrigated about 6%of the country's cultivated land, produced about 8%of the country's grain, 9%of meat, 11%of fruits of fruits. , 12%of vegetables, grain output has stabilized for more than 100 billion kg for many years.
