SU1667715A1 - Method of grain and leguminous crops treatment before harvesting - Google Patents

Abstract

The invention can be used in agriculture for harvesting crops with drying of plants at the root and accelerates drying, reduces the consumption of soil nutrients and increases the utilization of stored nutrients by the plant. Before harvesting, a voltage of more than 3 kV is applied to the stem relative to the soil. After drying and ripening on the root, the plants are mown and threshed.

Description

The invention relates to agriculture and can be used for harvesting grain crops with drying of standing plants.

The purpose of the invention is to accelerate the drying, reduce the consumption of soil nutrients and increase the full use of the stored nutrients by the plant.

The method is carried out as follows.

On the stems of plants to be harvested and at the end of the growing season, a high voltage of electric current is applied to the soil. After ripening and drying, the plants are mown and threshed.

For example, in order to harvest soybean, when the first signs of transition to the ripening phase (browning of the first legumes) appear, a voltage of more than 3 kV is applied to the stem relative to the soil. After the browning of all the bobs and stems and their drying (usually in two weeks), the soybeans are mown and threshed. For electrical treatment, weeds can be used to kill weeds with electric current. In the case of a known electrospark treatment of a plant, a clot is formed in the stem from coagulated proteins in cells and conducting putch gels. After this treatment, the lower part of the plant continues to grow with the growth of lateral shoots that impede the subsequent threshing.

In the proposed method, the voltage applied to the stem causes the passage of electric current from the point of contact of the electrode to the stem to the soil, which leads to the destruction of cell membranes in the lower part of the plant and, consequently, the flow of juice from them into the intercellular space.

interrupted, which accelerates the drying out of the plant and reduces soil consumption of nutrients.

The electric current destroys only the plant cells, and the conductive paths remain intact, so the living part of the plant, located above the place of current supply, begins to suck the juice through the conductive paths of the destroyed part of the plant until it begins to experience a lack of moisture, as the destroyed cells of the root no longer absorb moisture from the soil. Thus, the plastic substances accumulated by the plant at the time of electrotreatment are fully utilized by the upper part of the plant in the process of completing its growing season.

Using the proposed method for harvesting soybeans allows for two weeks.

reduce the time of harvest, get seeds of higher quality. In comparison with the electric-spark treatment, the proposed method is safer, since a lower voltage is sufficient for its implementation.
