Abstract

The invention can be used in agriculture during the harvesting of irrigated plants and reduces the yield loss and simplifies the method of harvesting. When harvesting alfalfa, mowed plants are placed in rolls 2 with the location of the plants and the roll axis across the irrigation furrows 1. At the same time, the furrows 1 form under the rollers 2 aeration channels 3 that accelerate the drying of the plants in the rolls 2. The width of the rolls 2 is chosen according to their speed drying out. After drying the rolls 2 pick them up. The method does not require special devices for the formation of aeration channels 3. Laying plants across furrows 1 reduces crop losses when selecting rolls 2 by blocking the furrows with 1 stalks of plants. 2 Il.

Description

The invention relates to agriculture and can be used when harvesting irrigated plants, for example, hay, hay and seeds.

The purpose of the invention is to reduce yield losses and simplify the method when working in fields with irrigation furrows.

Figure 1 shows a diagram of an implementation of the proposed method; Fig. 2 - the same, a top view.

The method is as follows.

When mowing plants at the same time as flattening, the laying of mowed plants is carried out across the irrigation furrows 1 into wide rolls 2, and the width B of the roll is determined from the expression

Chopt where L is the working width of the mower, m;

Q is the yield of plants, kg / m ² ;

Chopt - the optimal reference weight of the mown green mass in the roll, kg / m ² .

In this case, the grooves 1 form aeration channels 3 under the rolls 2.

After the mowing mass is dried up to the required humidity, depending on the type of feed (crushed, unmilled. Pressed hay with drying by active ventilation or in the field, haylage), a roll is selected.

The proposed method of harvesting irrigation plants can be carried out on irrigation alfalfa as follows.

For “irrigation alfalfa in Central Asia, experimental studies have established that the optimal (fast-drying) is the reference weight of the green mass in the rolls in the range of 2.6 - kg / m ² . Based on this, first determine the average biologically ethical yield of alfalfa (for example, 1.6 kg / m ² ), and by measuring the width of the mower of the mower-conditioner header (5 m), the proposed width determines the installation width of the exhaust (swath-forming) window of the header: V ~ 3m.

To implement the method using forage harvesting machines with increased cross-country ability (with dual wheels or on caterpillar tracks).

The method simplifies the process of conducting harvesting operations, since it is not necessary to equip the harvesting units with additional devices for mowing plants with different stubble heights, forming aeration channels, mowing high stubble when selecting rolls. In addition, laying the mass in wide rolls allows you to maximize the use of the solar-wind effect on the drying process of plants, the roll wrapping operation disappears. When selecting rolls, the loss of mowed plants from under-harvesting is reduced due to the overlapping of the width of the furrows by the stems of the plants.

Claims (1)

Claim A method of harvesting plants, including mowing plants, stacking them in rolls with the formation of aeration channels beneath them, located across the axis of the roll, and selecting rolls after drying, about t and - 4 and with the fact that. in order to reduce crop losses and simplify the method when working in fields with irrigation furrows, aeration channels are formed by arranging the axis of the roll and the plants in it across the irrigation furrows.
