RU2488990C2 - Method of biological control of cannabis at farm fields under conditions of yakutia - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. The method includes the creation of green-manured fallows by plowing in the green mass of cannabis and oats. At that in the first year, green-manured fallow is created by plowing in the green mass of cannabis prior to blooming, from the second year by the faster growth of green mass of oats grown from prevernal sowing - in late May, early June, followed by plowing in the mass of cannabis prior to blooming by plowing in along with the green mass of oats in earing phase, and from the third year by the repetition of methods to control from the second year with alternating the sowing of major crops.

EFFECT: method enables to destroy cannabis gradually at farm fields without the use of herbicides and other chemicals.

Description

The invention relates to agriculture, in particular to methods of biological control of hemp on arable land in the conditions of Yakutia.

The proposed methods can be used as cheap, highly effective measures for the destruction of hemp growing on abandoned, degraded arable land and planting potatoes, vegetables in the conditions of Yakutia.

Since the period of perestroika, the collapse of state farms and collective farms, arable lands have been abandoned, agricultural measures have been taken to restore soil fertility, as a result of which arable lands are overgrown with weeds, including hemp, salted, degraded, most of them transferred to hay and pasture meadows.

At present, in order to restore the fertility of the soils of abandoned lands, it is first necessary to free them from weeds and hemp, the overgrowth of which is huge on the abandoned arable lands of Central and Southern Yakutia.

The closest analogue of the invention is the patent "Methods of making green fertilizers" No. 2006105404 / .21. However, this patent proposes only the use of natural herbs as green manure in the LPH of the population, and the patent does not provide for the destruction of wild hemp.

As weed fertilizers, natural weeds, including hemp, are used in the Far Eastern State Agrarian University on the fields of the specialized potato-growing peasant-farm farm "Shchegorets" under the direction of O. Shchegorets. (Shchegorets O.V. Biologization of potato cultivation technology in the Amur region: abstract. Diss ... Dr. agricultural sciences. - M., 2008. - 47 p.).

Traditional methods of control, such as plowing, mowing and destruction by treatment with herbicides, destruction by fire at the end of the growing season, after seed ripening, have no effect, since hemp seeds that have crumbled and survived give a good harvest next year.

Given this, we have developed methods of biological control of hemp on arable land in the conditions of Yakutia, which are carried out according to the following scheme (figure 1):

- in the first year due to the creation of green manure by plowing the green mass of hemp before flowering, since the green mass of hemp is a good green fertilizer;

- from the second year, by inhibiting the growth of hemp plants on sideral pairs, the outstripping growth of the green mass of oats grown from early spring sowing of oats (late May to early June) with a depth of embedding of oat seeds by 3-5 cm with the subsequent destruction of the green mass of hemp before flowering by plowing together with the green mass of oats in the earing phase;

- from the third year, the methods of struggle of the second year are repeated with the alternation of crops of the main crops

The technical result of the proposed methods of biological control of hemp is the gradual destruction of hemp on arable land without the use of herbicides and other types of chemicals.

Claims (1)

A method of biological control of hemp on arable land, including the creation of green manure by plowing the green mass of hemp and oats, characterized in that in the first year green manure is created by plowing the green mass of hemp before they bloom, from the second year outrunning the growth of green mass of oats grown from early spring sowing - at the end of May, at the beginning of June, followed by plowing the hemp mass before flowering by plowing together with the green mass of oats in the earing phase, and from the third year repeating the methods of combating the second year with alternation m crop of major crops.
