(5) METHOD OF WATERING

one

The invention relates to agriculture, households, and in particular to methods of irrigation by sprinkling.

There is a method of irrigation, in which repeated irrigations, in order to save water, are carried out with reduced norms lJ.

The disadvantage of this method is the lack of stimulation of the development of plants by activating irrigation water and over-wetting the soil under the machine, which prevents the use of any effects on the water and plants simultaneously with irrigation.

The closest to the technical essence of the invention is a method of stimulating the development of plants, including watering plants with the issuance of irrigation norms and with simultaneous activation of irrigation water. The activation is carried out by electrification, carbonation and the simultaneous introduction of trace elements. 2.

However, this method has high irrigation water consumption to ensure optimal moisture during the irrigation period and insufficient crop yields due to flooding of roots, disturbing diet, and therefore the limiting factor of plant growth is not electrification and carbonation, but the provision of root aeration her ,

Thus, the disadvantages of the known irrigation methods should be considered excessive water consumption to ensure optimal inter-irrigation soil moisture, increased and unproductive evaporation of water from the rain stream, moist soil and plants, flooding the plant roots, reducing the activity of microbiological

20 processes in the soil, the transfer of readily soluble minerals to the plant-inaccessible Zegli layers, salinization of the soil, delayed photosynthesis of plants after watering for 1-2 days and the resulting effectiveness of any stimulating effects on the soil, water and plants, is low.

The aim of the invention is to reduce water consumption, increase soil fertility and yield of agricultural crops.

The goal is achieved by the fact that watering is carried out with variable rates in certain areas, and at night they give out a moisturizing, and during the day - a refreshing rate on the area adjacent to the watered one, followed by alternating areas. The method can be carried out, for example, using a wide-range circular action sprinkler.

The drawing shows an irrigation scheme for a wide-circle circular action machine.

To implement the method, the irrigated field is divided into fixed areas.

A sprinkler machine 1 is installed on the irrigated field 2, divided into fifteen fixed sections, and connected to a fixed pipe 3 for supplying water from the pumping station to it. In the drawing, dotted lines along the radius indicate individual sections of the floor, solid lines in a circle indicate the place of night watering in these areas, and the dotted line shows the place of day irrigation for fifteen days.

The method of irrigation is carried out as follows.

The refreshing and irrigation rates of irrigation and, consequently, the speed of movement of the machine are pre-determined so that the irrigation rate in one area is given out overnight, and the refreshment rate is given out in a day (day time) in three areas.

Thus, for fifteen days, 3 irrigation irrigations will be produced, which is equivalent to the normal operation of the machine with irrigation norms that ensure optimum soil moisture during the irrigation period. Sprinkler machine almost pour out

Copichesto water. but

the same

with alternation of plots with different degrees of irrigation on the field, the productive use of transpiration fumes from the watered plots of the floor and from the rain stream increases. This, taking into account the enhanced mineral nutrition and hardening of plants, allows in the proposed irrigation method to reduce the consumption of scarce water

less than 50 while improving soil fertility and increasing yields.

Control of irrigation efficiency and optimal growth stimulation.

day plants against the backdrop of a favorable set of environmental factors, when the roots of the plants are not flooded, allows you to increase the consumption of plants that are necessary at this stage of development

plant minerals and trace elements, increase plant resistance (hardened) to the effects of adverse environmental factors, ensure the preservation of air humidity

over the field, eliminate daytime depressions of plant photosynthesis, maintain the optimum soil moisture during the inter-irrigation irrigation irrigation and therefore, extend and

enhance the activity of microbiological processes in the soil, improve soil fertility and ensure high yields of agricultural crops.
