The water pump was installed yesterday afternoon and powered on to start pumping water. It has been pumping for almost 20 hours now.

The theoretical pumping head of the water pump is 40 meters, and the maximum pumping flow rate is 140 cubic meters per hour.

The vertical height from the reservoir to the mountainside is just over 20 meters, which is half of the maximum lift of the water pump.

The fish pond on the mountainside is only four acres in size. It may have been used to grow rice in the past, and the bottom of the fish pond is flat. This time, Wu Quan was asked to help dig out the fish pond with an excavator.

The place where the water comes out of the mountain spring was dug, and a deep pit with an area of ​​one minute was dug at the outlet of the mountain spring.

Now except for the outlet of the mountain spring, bulldozers are used to push away the layer of mud on the bottom surface of the fish pond and pile it on the land around the fish pond. The entire fish pond work was completed in one day.

.

Unlike the fish pond on the top of the orchard, the excavator took almost four or five days to dig, and the bulldozer took even more time. By then, the money for Wu Quan's excavator would be quite a lot.

However, the next few fish ponds are almost like the fish ponds on the mountainside, with flat bottoms. They must have been used to grow rice for many years.

But in this way, Wu Fei's workload of clearing the bottom of the pond will be reduced a lot. If there is no time or if you want to save trouble, you can seal the water outlet and fill the fish pond directly.

After about 20 hours, the water in the fish pond is almost one meter deep. Pressing the water pump can produce up to 140 cubic meters of water per hour, which is almost 2,800 cubic meters in 20 hours.

A fish pond with an area of ​​4 acres is almost 2,700 square meters, and the depth of the fish pond is only 2 meters. Even if the entire fish pond is filled with water, it will have 5,400 cubic meters of water.

According to the theoretical water pump output of 140 cubic meters per hour, it would take 38 hours to fill the fish pond. However, 140 cubic meters is the most ideal state, and Wu Fei would be very satisfied if he could get 120 cubic meters per hour.

In the fish pond at the top of the orchard, ever since Wu Fei placed the Lingquan seeds in it, even if there are several large and small mountain springs gushing water out, the amount of water in the fish pond has not increased much.

Even the bottom of the fish pond was not submerged. The main reason was that the area of ​​​​the fish pond was too large and the amount of spring water was too small. You know, in the few months since Wu Fei returned home, there were two relatively heavy rains, and other times it was small.

The rain dries up when it falls on the ground.

The water from those mountain springs is still flowing out, which can be said to have lasted long enough. Some wells in the village began to limit their supply half a month ago.

The village has its own tap water. On the mountainside in the other direction from the tea garden behind Wu Fei's house, a water tower was built a few years ago to draw natural spring water from the mountain. The water pipes were then installed at the door of every household.

The money for repairing water towers and laying water pipes comes from poverty alleviation funds specially allocated by the county. However, each household has also installed a special water meter, because everyone still needs to pay for the electricity to pump water to the water tower.

Therefore, in the past, the wells that people dug at home were not completely abandoned. Many people would buy a submersible pump and throw it into the well. When using water, they would still use their own free water. Unless the water in their own wells was not enough, they would use the village water.

Inside the water tower.

There hasn't been any heavy rain for a long time, and many wells are a bit short of water. But for the time being, there is no problem for everyone to drink water. The water tower built in the village draws spring water, even if it encounters a severe drought that only occurs once in ten years.

The phenomenon of water outage.

However, these have little to do with Wu Fei. Although the amount of water in the fish pond increases slowly, the fish pond on the mountainside will be filled up in another twenty or thirty hours of pumping.

At that time, it will be necessary to move the water pump to the top, and then pump the water from the fish pond on the mountainside into the fish pond above.

To fill the above fish pond with water, at least two or three small fish ponds are needed. At that time, the water pump will have to be moved several times.

Fortunately, the water pump only weighs 300 kilograms, and Wu Fei and his brother-in-law can lift it up. Don’t carry it all the time, just lift it for a while. Once you get on the trolley, you can walk along the newly built road.

Move to the top.

It was almost lunch, so Wu Fei didn't go up the mountain anymore. He just waited at home for everyone to come back from work and have dinner.

After eating, everyone would rest for about half an hour before doing anything. During the break, Wu Fei asked his father, "Dad, what are you planning to do in the morning?"

All the land where the greenhouse needs to be installed has been prepared, and the next work needs to be done before the greenhouse can be installed. I originally thought that the greenhouse would be installed today, but who knew it would be postponed to tomorrow.

"We are going to burn the ashes today. After so many days, the weeds and trees have dried up and can be burned."

Dad said to Wu Fei: "I heard from the weather forecast that it may rain in the next few days. If you don't burn it now, it will be difficult to burn after it rains."

In fact, plant ash is a very good fertilizer. The main component is potassium carbonate, of which potassium content is the largest, ranging from 6% to 12%. More than 90% of it exists in the form of water-soluble carbonate, followed by phosphorus.

, is 1.5%-3%, and also contains trace nutrients such as silicon, calcium, sulfur, manganese, iron, magnesium, boron, zinc, copper and molybdenum.

Moreover, the nutrient content of plant ashes produced by burning different plants is also different.

In rural areas, plant ash is an inorganic farmyard fertilizer with wide sources, low cost, comprehensive nutrients and obvious fertilizer effect.

In fact, the most important thing is the low cost. Many times it is burned out by the way. This is what happened to Wu Fei this time.

The weeds and miscellaneous trees in these fields can produce at least dozens of tons of plant ash. However, many places have banned the burning of plant ash in recent years. Small-scale operations are fine. Even if they are discovered, they will not be bothered. At most, it will not hurt.

A few words of caution.

The main concern is that burning plant ashes in the wild will cause forest fires. The season for burning plant ashes is generally when the weather is dry, and forest fires are most likely to occur.

However, Wu Fei's family does not need to worry about fire this time when burning plant ashes. The place where the plant ashes are burned is in several small fish ponds at the foot of the mountain, and the surrounding vegetation has been cut clean by tractors.

Even the ground was plowed several times, but there was nowhere to burn except the fish pond where the plant ashes were burned. As for the bit of smoke and dust from burning the plant ashes, it was nothing.

You know, when Wu Fei was young, every year when the late rice harvest came and the weather was sunny for a long time, almost every household would burn plant ashes.
