I walked into Niejia Village, but I saw fennel green and red strawberries in the vegetable greenhouses. Chen Yaying, the female party secretary of the village party branch, said that building sheds and growing vegetables is a good thing. It can increase the income of the people. That is, the pouring of water has caused headaches for everyone. It turned out that the two wells stayed open all day and night, and the expenses were largely ignored. It was also often because of dishwashing and the fact that there was an argument and even a big fight that hurt the neighbors for many years. Later, Nie Guocheng, the director of the village committee and the water manager, came up with a good idea: In the contracted shed, an IC card water meter was installed, and the pump was replaced with a variable frequency pump. Who could insert the card into the water and how much was spent? Money, the words on the table, and the heart. Chen Yaying said: “If there is no measurement, control the water, the two pumps in the village are open at the same time, and some people do not pour water. With the support and assistance of the water department, we implemented the irrigation project and added a separate IC. Card water meter, now a water pump can meet the water demand.Also, since the use of IC card measurement, the villagers spend money to buy water, all know that saving, ready to use water at any time, their own control, much less conflict." The power and maintenance costs of the wells were bought one by one and the two wells were compressed to one eye, saving more than half of the water and electricity.
The author saw in Nie Jiacun that the owner of each greenhouse had a plastic bag and a bucket underneath. Nie Guocheng said that adding a one-way valve to each water pipe can be used to fertilize water while fertilizing it. In professional terms, this is called "water-fat coupling," which saves manpower, reduces waste, and saves costs. At present, the vegetable greenhouses in Niezhuang Village in Zhang Town are in full swing, and the days of ordinary people are even more prosperous. With the “Central Document No. 1â€, the spring breeze of farmland water conservancy construction is being implemented, and the living standards of the people are even higher.
