SU1616542A1 - Method of harvesting seed-bearing plant of agriculturing crops - Google Patents

Abstract

The invention can be used in agriculture when harvesting seeds, for example, soybeans, when seeding seed crops in strips with transferring strips of another crop, and reducing the weediness of seeds by another crop. Soybean plants in the stage of complete leaf fall are mown and placed in rolls on stubble 15–20 cm high of the previously mown stems of another crop, such as winter rye or wheat. After the rolls dry, they are picked up and threshed. 2 Il.

Description

The invention relates to agriculture and can be used for harvesting soybean seeds, cut in strips with alternating strips of another crop.

The purpose of the invention is to reduce the contamination of seeds with another culture.

Figure 1 shows the layout of the testis bands and another culture; figure 2 - scheme of the proposed laying rolls of testes.

The proposed method of harvesting soybeans for seeds is carried out in the following sequence.

In the field prepared in advance and marked out in the autumn, every 4.2 m of the grain crop SZ-3.3 or SZU-3.6 are sown strips of winter rye or wheat 3.6 m wide, and in early spring between strips of winter rye or combed wheat the cultivator of the USHI construction is sowed with a ridge method in a row of soybean between 70 cm between rows. In the stage of full ripening: the stripes of winter rye or

Wheat is harvested by direct combining with a SK-5 Niva combine, equipped with a 4.1-meter cutterbar, and a PUN-5 straw chopper. Cutting height see

Soybean plants in the stage of complete leaf fall are mowed with a SK-5 Niva combine, equipped with a ZhRB-4.2 header, at a height of 5-7 cm, 3 rows in one pass and laid on the stubble of winter rye or wheat. On the cutting unit of the header ZHRB-4.2 on the left side set the shield 1.8 m long, protecting the stubble from the cut. On the way back, the remaining three rows are cut, which are laid on the stubble of the neighboring strip. Thus, on each strip of a stubble bed of winter rye or wheat, sticks of 6 rows of soy are formed. After 10-15 days, those. after drying, the rolls are picked up with a SK-5 Niva combine, equipped with a header with a drum-type pick-up, and threshed under the following modes: number of turns

When the height of the winter crop is less than 15 cm, the mass of soybean plants is mowed down and placed on the stubble close to the soil, and in some places it touches the ground, as a result of which the swath is poorly blown and dries very slowly. With a height of stubble more than 20 cm, stubble sticking to the soil is observed due to the weight of the roll from soybean plants. which also leads to a decrease in the space between the roll and the soil, and in some places to the contact of the roll of the earth.

Seeds, obtained after the selection and threshing of the proposed method, do not require the high cost of tertiary treatment, sorting and drying.
