There are 185 households in Niejia Village, Zhang Town, Shunyi District, Beijing, and 1,165 acres of agricultural land. In recent years, under the guidance of the relevant policies of the municipal government, the village has started facility agriculture, built 380 acres of vegetable greenhouses, and installed all water-saving facilities such as drip irrigation, and used IC card water meters to save water and electricity. Save effort, get multiple benefits in one fell swoop.

When I walked into Niejia Village, I saw the green fennel and the red strawberry in the vegetable shed. Chen Yaying, the female secretary of the village party branch, said that building sheds and growing vegetables is a good thing, which can increase the income of the masses, but watering the ground once caused everyone a headache. It turned out that the two motorized wells were open day and night, not to mention the large expenditures, and people often quarreled or even fought around about pouring vegetables, hurting the harmony of the neighborhood for many years. Later, the director of the village committee and waterman Nie Guocheng came up with a good solution: install IC card water meters in the greenhouses contracted by each household, and replace the water pumps with frequency conversion. Everyone can plug in the card to water the ground and use as much water as possible. Money, there are words on the table, and counts in the heart. Chen Yaying said: "When there is no metering, water use is controlled. Two pumps in the village are on at the same time, and some people can’t pour the water. With the support and help of the water affairs department, we implemented the ground irrigation project and installed the household IC Card water meters, now a single pump can meet water demand. Moreover, since the adoption of IC card metering, villagers spend money to buy water, knowing that it saves money. Water can be poured at any time at any time, and the contradiction is much less. "At the end of the year, deducted Electricity and maintenance fees for pumped wells are purchased and plugged once, and two wells are compressed to one, saving more than half of water and electricity.
