The hot wind is drier over the steppe, orchards and vineyards, the sun is mercilessly beaming. The earth is covered with a mournful network of cracks. The leaves are helplessly dropping ...
How to water drained fields and gardens if there are no large ponds nearby? Professor N. Kholin, working on a solution to this problem, spoke about his interesting experiments.
Back in 1936, the Soviet scientist V. Tugarinov conducted a convincing experiment. A small sand pyramid was poured on the territory of the Agricultural Academy. From its top to the base was a vertical trunk, connected at the foot of inclined pipes. The temperature and pressure inside the hill were lower than in the environment, and warm outside air gravity entered the mine, on the cold walls of which dew appeared. Her accumulated more and more. In the end, it began to flow through the pipes. The Water Factory was producing more moisture as the weather got hotter. The calculation showed: if under the sky of Crimea an installation with a condensing surface of one square kilometer will operate, then in the summer in ten hours it will be able to catch 4,500 cubic meters of water!
This idea of Professor Tugarinov fascinated the engineer G. Shendrikov and me. We understood that it was not enough to irrigate the dried land: surface watering could not be beneficial, but to the detriment of plants. With rapid evaporation, a crust forms on the soil - an obstacle to the penetration of air to the roots. And they will receive very little moisture. It is known that the great transformer of nature, Ivan Michurin, has clearly demonstrated how deep top dressing works well on plants. On this basis, we decided to test and deep watering, bringing moisture closer to the roots. So the idea of a hydraulic drill was born.
... A tank truck drove into the field. Water under pressure rushed through a hose to a hydraulic drill - a long section of a water pipe with a steel tip. The tip touched the ground near the stem of the vine. In a few seconds, the drill went into a blurry hole to a depth of 60 centimeters. A scanty ration was injected into the root nutrition zone — only four liters of water. Then the same thing was done with other plants.
After 10 hours, a section of the soil showed that under the bushes there were already not four, but 15 liters of water each! After two days, its quantity has increased. So condensation hills are not needed. The trunk laid by the drill turns into an individual “water factory” for each plant.
As calculated, in the Central strip of the USSR over a section 100 km long at a five-meter wind speed, several large freshwater “flies” per day
reservoirs. We believe that it is hydrobores that can “land” them.
Here, for example, what happened in the Crimea during the drought of 1957. The soil was drained. Adult vines drooped, leaves began to turn yellow and fade. Younger vineyards were even more difficult. Planted on 15 thousand hectares, they barely gained strength. The root system of plants has not yet become stronger, and drought threatened to destroy them. Surface irrigation of one hectare would require 800 cubic meters of water. It was impossible to get it in such quantity among the sultry steppe. Then winegrowers used hydrodrill. Each bush received only four liters of moisture, the rest was given by condensed air vapors. After a few days, the plantations became unrecognizable.
Using a hydraulic drill, you can introduce into the soil nutrients dissolved in water, poisons that act on weeds and pests. At the same time, productivity is almost doubled.
Convenient hydraulic drill for planting. In Odessa and other areas, this method was used in 1959 when laying new vineyards on an area of 100 thousand hectares, and the work cost four times cheaper than usual. In the wells washed by the water stream, the cuttings took root well, earlier they acquired the ability to bear fruit.
The hydraulic drill is also used for draining bogs and in the fight against salinization of land.
Continuing the research work in the team of the All-Union Scientific Research Institute of Agricultural Mechanization, we have created a set of prototypes of machines for hydraulic drilling, feeding and planting of different crops. Up to 360 steel drills are located on the rotating shaft of one of the machines, through which nutrients and “vaccines” against various plant diseases will be introduced into the soil simultaneously with watering. Towed by tractors, such machines will go into the dry season through the fields, returning to life dying vegetation.
We are now dreaming of a time when hydraulic drills will help to conquer vast areas from the deserts in order to return them to blooming people. https://bestcasinocanadaonline.com/
