Method of irrigation of orchard

FIELD: agriculture.

SUBSTANCE: method comprises preparation of a field ditch and an irrigation furrow with opening the shoulder of the field ditch, into the shoulder of the field ditch a plastic bottle with the volume of 1.5-2 litres with a truncated bottom at the height of 3 cm is placed, the bottom is placed in the cut place of the bottle with the reverse side, the bottom serves as the means of water start and turning off the water flow into the irrigation furrow, and at low flow rates of water the start and turning off the water after finishing watering is carried out by the bottle lid.

EFFECT: simplification of the method and improvement of the quality of irrigation.

 

The invention relates to agriculture and can be used in fruit growing in the implementation of irrigation of an orchard the most common way by furrows. The present invention is especially effective for farming and leasing land use, as well as in gardens and suburban areas with small areas of an orchard.

The known method of water supply from the output furrow irrigation furrow irrigation of an orchard furrow, when the lead edge of the furrow opposite furrow irrigation is done Prokop and water enters the irrigation furrow. The disadvantage of this method is that the irrigation water in the irrigation process blurs the lead edge of the furrow, a large part of this soil is carried away by water by furrow irrigation, increasing water flow and this flow rate is difficult to regulate. After watering the restoration of the lead edge of the furrow for the termination of water delivery in irrigation furrow becomes a very tedious process. [Armisen D. V., Lysogorov S. D., Balan, A. G. Reclamation farming. Moscow, Publishing house "Kolos", Moscow (1966).]

The closest technical solution is a method in which water flow from the output furrow in furrow irrigation is carried out using siphons. [K. K. bityukov, Dorozhko P. K. Irrigation of agricultural crops in the steppe regions. Moscow, �te-in "ear", 1965.]

The disadvantage of this method is that the charge drains and their installation in the operating position takes a lot of time, when the water level drops in the output furrow they often are disabled.

The purpose of the invention is the simplification of the method of water supply from the output furrow in furrow irrigation when watering fruit garden, improving the efficiency and quality of irrigation.

This object is achieved in that in the lead edge of the furrow is placed a plastic bottle with a volume of 1.5-2 liters with a truncated bottom 3 cm, which is installed in the cut of the bottle the reverse side provides a means for the water start and shutoff of the flow of water into the irrigation furrow, and at low flow rates the water start, and the overlap of water after irrigation produced a bottle cap.

The method is as follows.

In the lead edge of the furrow in front of each furrow irrigation until the beginning of the irrigation is done Prokop width 10-11 see this Prokop horizontally towards the irrigation furrow is placed a plastic bottle with a capacity of 1.5-2 liters. The bottle pre-cut the bottom 3 cm, it is the bottom of the reverse side is inserted into the cut bottle and further serves as a means of start-up of water in the furrow and covering of water flow in furrow irrigation after irrigation.

Laid in Prokop bottle covered with earth to a height�you lead edge of the furrow and well tamped, to prevent seepage of water along the edges of the bottle.

If you want a small flow of water, the start and the blocking of water after irrigation produced a bottle cap. If necessary, the high costs of water, the neck of the bottle is cut into 3-5 cm, and the start and termination of water supply are cut off the bottom of the bottle, which is the reverse side in the place of the cut. Thus, this method is more simple, less time consuming, does not require much cost and dolgoon in operation.

Method of irrigation of an orchard, including the preparation of lead and irrigation of furrows with the opening edge of the exhaust grooves, characterized in that the lead edge of the furrow is placed a plastic bottle with a volume of 1.5-2 liters with a truncated bottom 3 cm, which is installed in the cut of the bottle the reverse side provides a means for the water start and shutoff of the flow of water into the irrigation furrow, and at low flow rates the water start, and the overlap of water after irrigation produced a bottle cap.
