RU2239298C1 - Method for burdock control - Google Patents

Abstract

FIELD: agriculture, farming.

SUBSTANCE: invention can be used for control of weeds - cobwebby burdock, large agrimony. Method involves alternating cultures in crop rotation. The following alternating cultures are used as crop rotation against burdock: 1) orchard-grass, 2 parts; perennial rye-grass, 3 parts; smooth brome-grass, 1 part; 2) grasses after 1 year using; 3) grasses after 2 years using; 4) yellow sweet clove or lupine; 5) potato; 6) rye, 2 parts; triticale, 1 part. Mowings of perennial grasses mixture are carried out before formation burdock reproductive organs. After the last mowing field is treated by milling and chisel cultivating tools. Method provides effective control of burdock in weedy fields.

EFFECT: improved method for control.

Description

The invention relates to agriculture and, in particular, to weed control - cobweb burdock, burdock burdock big.

A known method of destroying a malicious two-year-old burdock and a burdock burdock large, including the introduction of crop rotation, with the ability to suppress individual weeds. However, this does not ensure the complete destruction of mugs / Fisyunov A.V. Weed plants. - M .: Kolos, 1984 /.

A known method of alternating crops of soil-protective crop rotation, including sequential sowing of crops:

1 - oats with subseeding of clover and timothy,

2 - perennial herbs 1 year of use,

3 - perennial herbs 2 years of use,

4 - oats or spring barley for grain,

5 - winter rye,

6 - potatoes.

The development of such a crop rotation allows to achieve a minimum field weediness by burdock. However, when transferring to the arable land the former camps of small cattle, which are usually heavily littered with burdock, this alternation of crops does not provide sufficient clearance of the site / Bzikov MA, Shorin P.M., Misik N.A., Agaeva A.K. Soil fertility and crop yields in the mountainous area // Information leaflet of SBSTI, No. 68-088-03 /.

The purpose of the invention is biologized and ecologic suppression of burdock weed.

The method is as follows.

When transferring a camp to arable land, the site is first cleaned of stones in the summer-autumn period. Then it is treated with a milling tool to a depth of 6-10 cm in order to cut off the apical part of the burdocks, provoke viable seeds and organs of vegetative propagation of the weed to germinate, and create a carefully cut soil surface. In late August - early September, a mixture of perennial cereal grasses is sown - the hedgehogs of the national team, multi-cut ryegrass and beechless bonfire in a ratio of 2: 3: 1 with sowing fertilizers. The seeding rate of grass mixtures is increased by 25-30% in comparison with the recommended. Perennial cereal grasses with a different type of fibrous root system provide continuous penetration of the arable soil layer, intensive absorption of available forms of nutrients, which weakens the growth of burdock. During the growing season, during the years of use, the mixtures of grass mixtures are carried out before the formation of the reproductive organs of burdock to prevent seed propagation of weeds. The cereal mixture is used for 2-3 years, feeding with mineral fertilizer in the early spring and after each mowing, which increases the competitiveness of the grass mixture. In the last year of using herbs, after the cutting, the site is treated twice with chisel and milling tools, stimulating the germination of burdock and its destruction. After presowing treatment, alkaloid-containing plants are sown - lupine, yellow melilot, which inhibit the development of burdock and soil-borne pests, which allows potatoes to be placed in the next crop. In autumn, plowing is carried out to the depth of the arable layer of the soil, which ensures the purification of the cultivated layer from viable burdock, and in the spring they plant potatoes. In the process of caring for the potato, the plot is freed from the preserved burdock plants.

After potatoes, a mixture of winter rye and triticale in a ratio of 2: 1 is used for biaxial use for fodder purposes or single-crop for grain. A mixture of rye and triticale inhibits the surviving burdock plants.

Example: In a crop rotation planted in 1997 on the site of a former camp, the initial clogging by burdock was 8-10 pcs./m ² , and at the end of its development, the plot was in a clean state of burdock.

Claims (1)

A method of combating burdock, including crop rotation in crop rotation, characterized in that the following crop rotation is used as a burdock crop rotation: 1 - hedgehog team 2 parts, multi-ripe ryegrass 3 parts, beechless campfire 1 part; 2 - herbs 1 year of use; 3 - herbs 2 years of use; 4 - yellow clover or lupine; 5 - potatoes; 6 - rye 2 parts, triticale 1 part, while the mowing of a mixture of perennial herbs is carried out until the reproductive organs of burdock are formed, and after the last mowing of the grasses, the site is treated with milling and chisel tillage tools.
