Abstract

Usage: in agriculture for the cleaning of the nyandra physicloid testes. SUMMARY OF THE INVENTION: The plants are mowed at a height of 12-15 cm and the mown mass is laid on the stubble in spreading bed to dry. Then the stubble is mown with simultaneous selection and threshing of the mass laid on it when the moisture content of the latter reaches 20-22%. The method provides a reduction in losses of seeds n.

Description

The invention relates to agriculture, in particular to methods for harvesting Nikandra's physalis-like seed plants.

There is a known method of harvesting the testes of agricultural crops, including mowing the stems of the testes and laying them in rolls on the stubble of pre-mown stems, another culture.

The disadvantage of the method is that it is necessary to carry out a breakdown of the field for the strip sowing of two crops. In addition, nikandra is a culture with high humidity during the period of harvesting the testes and a high yield of ground mass, therefore the stern of another culture hardly keeps on its surface nicked rolls of nikandra. During the formation of the roll of nikandra, the thin shell of the fetus is damaged — dry years filled with small seeds. The rate of drying of the beveled mass of nikandra in the roll is insignificant, which leads to rotting and shedding of seeds.

Closest to the proposed invention is a method for harvesting seeds of tall stem free-flowing crops.

Cutting plants with laying them in a roll on a high stubble, drying a roll and its subsequent selection by cutting the stubble with a header for direct combining.

The disadvantage of this method is that the plant mass of the harvested high-stem effluent culture is mowed and placed in a swath, while the mowed down Nikander mass with its juiciness (percentage of moisture: 82-86%) will dry out badly, which leads to loss of seeds from rotting and shedding.

The aim of the invention is to increase the completeness of the collection of seeds,

The goal is achieved by the fact that Nikandra plants are mowed at a height of 12-15 cm, terrassil is laid on the stubble, and selection and thresh are carried out at a humidity of the dried mass of 20-22%.

The positive effect of the present invention is that with this method, the completeness of the collection of seeds is increased by reducing the drying period of the mowed mass laid in the seedbed on the stubble, eliminating seed loss from rotting and scattering, are inevitable when placed in the swath .

With a height of less than 12 cm, the weight of the stubble slanted on the stubble will be close to the soil, and in some places it will touch the ground, resulting in a poor blown mass and slow flow - fxaTb, which will cause the seeds to fall from the ripe fruit and yield loss 6 c / ha. In the case of a cutting height of more than 15 cm, when the second cutting is done, long lengths of succulent stems will be delivered to the header and threshing, which will lead to additional moistening of the dried mass and, as a result, poor quality threshing and loss of yield.

When the final moisture content of the mass is less than 20%, the drying time increases, which leads to shedding of seeds from ripened year and yield loss. With a humidity of more than 22%, the mass is poorly threshed, which also leads to loss of seed

Example The harvesting of Nikandra's testes with a physicus-like one was carried out at 70% a year by a KPH-2.1 mower. The plants were mowed at a height of 12-15 cm, the stubble was laid on the curb to dry it to a moisture content of 20-22%, and the subsequent stubble was cut with simultaneous selection and threshing of the mass laid on it, it is produced by a Sampo combine at the lowest possible technical characteristics of agricultural implements (in our example, 7 cm).

The method provides high-quality threshing of seeds; they do not require additional cleaning after harvesting.

The invention of the method of cleaning the testes of nikandra fizalisovidnoy, including mowing plants on a high cut, laying the mowed mass on the stubble for drying and subsequent cutting of the stubble with simultaneous selection and threshing of the mass laid on it, differing in that, in order to increase the completeness of the collection of seeds, the mowing of the plants is carried out at a height of 12-15 cm, the laying of the mass on the stubble is carried out in the stem, and the selection and threshing is done at a humidity of the dried mass of 20-22%
