Abstract

FIELD: agriculture.

SUBSTANCE: to protect plants 2 from frost, cold air is fed into the heating boiler 8, which is heated with fuel or electricity to the desired value and is pumped under pressure through the distributors 4 to the arable unit. In the arable unit a perforated flexible hose 5 is brought to each plant, with an air flow regulator 6, connected to the distributor 4, winding S-turn the trunk of the plant 2 in height and having a plug on the end. The winding density depends on the amount of frost. The lower part of the plant 2 trunk with the perforated flexible hose 5 is wound with polyethylene film 7, and in the upper part there is a free outlet. Heating the plants 2 and the surrounding area is carried out with the discharge of warm air from the perforations.

EFFECT: improvement of efficiency of protection of plants from frost.

Description

The invention relates to agriculture, relates to methods and devices for protecting plants from frost: fruits and vegetables, trees, shrubs.

A known method of protecting plants from frost [1] by treating the soil with a solution of dimethyl sulfoxide A. The disadvantages of this technical solution are:

- low efficiency of using the method in horticultural and other similar farms;

- in environmental terms, is not a favorable technical solution.

Closest to the proposed is a method of protecting plants from frost [2]. When implementing the method, a gas heating apparatus is used, a supply pipe equipped with a compressor and gas-carbon dioxide plants connected in series with gases and carbon dioxide, a mixing chamber, to which a gas heating apparatus in the form of a solar energy accumulator made in the form of a cylindrical tank is connected by means of a compressor.

The disadvantage of this technical solution is:

- low efficiency and the inability to use it over a large area;

- the relative high cost of the heating method.

The purpose of the invention is to increase efficiency and reduce the cost of heating.

The goal is achieved by planting plants with a root system on the soil. A distributor is laid on the soil, to which perforated flexible hoses with a regulator are connected (Fig. 1). The regulator is a clamp and allows you to adjust the flow rate of the outgoing warm air from the perforated flexible hose. Flexible perforated hoses snake wrap around the trunk of the plants and have a cap at the end. The density of the winding depends on the size of the frost. The dimensions of the holes in a flexible perforated hose are determined on the basis of ensuring the heating of the calculated area, where Q is the flow rate of warm air supplied to the entire system; q _i is the flow rate of warm air leaving the perforated flexible hose, i is the number of perforated hoses equal to the number of seedlings.

The bottom of the plants around the perforated flexible hoses is wrapped in plastic wrap. This allows more efficient use of heat coming out of the perforation. The output of warm air from the top of the perforated flexible hose extends in different directions and heats all branches of the plant. The generation of warm air is carried out in a boiler with a valve in the heating, where cold air is supplied, which is heated by fuel or electricity to the required value. The boiler has an inspection cover and pressure valve. The pressure valve opens if the boiler exceeds the permissible pressure. The cold air is supplied to the boiler through the pipe, and gas through the inlet. At the end of the valves, plugs are provided (FIG. 2). The flow rate and temperature of the supplied warm air depend on the temperature of the air surrounding the plant.

Any type of fuel or electricity can be used as an energy carrier, it is especially effective to use natural gas since it is often necessary to work in places where there is no electricity supply.

In FIG. 1 shows a cross section of a method and apparatus for protecting plants from frost, a general view; in FIG. 2 - the same, top view.

Plants 2 with a root system 3 are planted on soil 1. A distributor 4 is laid on soil 1, to which perforated flexible hoses 5 with a regulator 6 are connected. The lower part of plants 2 is wrapped with plastic film 7 around perforated flexible hoses 7. Heat is generated in the boiler 8 with a valve 9. Boiler 8 has an inspection cover 10 and a pressure valve 11. Cold air is supplied to the boiler 8 through the pipe 12, and gas through the inlet 13. At the end of the distributors 4, plugs 14 are provided.

A method of protecting plants from frost is as follows. Plants 2 with a root system 3 are planted on the soil 1. A distributor 4 is laid on the soil 1, to which perforated flexible hoses 5 with a regulator 6 are connected (Fig. 1). The regulator 6 is a clamp and allows you to adjust the flow of outgoing warm air from the perforated flexible hose 5. Flexible perforated hoses 5 snake wrap around the trunk of plants 2 and have a plug at the end. The lower part of the plants 2 around the perforated flexible hoses 5 is wrapped with plastic film 7. This allows more efficient use of the heat coming out of the perforation. The output of warm air from the top of the perforated flexible hose 5 extends in different directions and heats all branches of the plant 2. The generation of warm air is carried out in a boiler 8 with a valve 9, where cold air is supplied, which is heated by fuel or electricity to the required value. The boiler 8 has an inspection cover 10 and a pressure valve 11. The pressure valve 11 opens in case of excess pressure in the boiler 8 of the permissible norm. The supply of cold air to the boiler 8 is carried out through the pipe 12, and gas through the inlet 13. At the end of the distributors 4, plugs 14 are provided (Fig. 2).

The proposed technical solution allows to increase the reliability of plant protection from frosts on agricultural farms with a large area. It is especially effective to use it in intensive gardening. This method will increase the yield of fruits and vegetables. It is especially effective to use in an area where frosts are frequent.
