How can farmers irrigate the terraces so high in the south?

Abstract: the terraces in the south are so high, how can farmers irrigate them?

Terrace is a special crop planting pattern in southern China, and it is also a method to make full use of land for production. Rice is the most frequently planted crop. Terraces are generally built halfway up the mountain, and the first step is staggered, which is very beautiful from the photos overlooking. Since we are growing crops, we must consider the problem of water supply, so how does the water get up when the terraces are so high? How do farmers irrigate?

The geographical conditions produced by terraces.

Terraces are most common in the south and can hardly be seen in the north. That is because Rain Water in the south is abundant and has many mountains, and there are not as many fields suitable for planting as in the plain areas. therefore, people in the south have come up with the way of developing mountains to build terraces, especially in Guangxi and Yunnan areas. moreover, terraces can not be built on any mountain, but must be convenient for water storage, lush vegetation, and good mountain environment, especially suitable humidity.

The main way of terraced irrigation.

Natural irrigation depends on heaven for a living. Southern Rain Water is rich, especially in summer and autumn, Rain Water is abundant, which can fully meet the needs of rice growth. According to the growth law of rice, it needs sufficient water to guarantee its growth in the early stage of transplanting, tillering stage and booting stage, while it is generally guaranteed by Rain Water in the south. However, there are times when it is less difficult for Rain Water to maintain rice growth. at this time, ordinary farmers will use Rain Water, who had saved in the early stage, to irrigate. When Rain Water is really too little, it will affect rice yield, which cannot be solved artificially in the early stage. but now the technology is advanced and there are modern advanced agricultural irrigation techniques.

Adjust measures to local conditions and store water for irrigation. The mountains that can build terraces are generally covered with luxuriant vegetation, and the natural environment on the mountain forms a small biosphere, which can be self-sufficient in Rain Water's abundant years. Generally speaking, after the construction of terraces, people will dig reservoirs near the terraces according to the location of the terraces and the natural conditions of the mountains, and the mountains themselves will have springs, and the reservoirs will be dug near the springs, which can not only accumulate water from Rain Water but also make use of the springs. When there is less precipitation in the later stage, the water sources of ponds and springs can be used for irrigation.

Dig canals to build reservoirs and divert water for irrigation. Modern irrigation technology is relatively developed. If Rain Water is not enough to meet the irrigation needs, we can also use modern irrigation techniques to dig ditches around terraced fields or build reservoirs directly. Mountain conditions are used to divert mountain spring water or accumulated Rain Water or reservoir water to terraced fields for irrigation. According to the experience of terraced planting management, digging ditches is the most effective way of irrigation, mountains are connected, ditches are the same, ditches extend in all directions, irrigation is very convenient.

With the development of modern agricultural technology, terraced irrigation has said goodbye to the shoulder-to-shoulder irrigation mode, solved the problem of farmers' terraced irrigation, the modern terraced planting technology has been very mature, and the terraced model has become a beautiful scenic line. overlooking the southern terrace staircase, full of vitality.
