RU2019944C1 - Sawing band - Google Patents

Abstract

FIELD: agriculture. SUBSTANCE: to enhance weed control, sawing band is covered with herbicides at points of seed attachment. Said herbicides do not affect the row crop cultures. Spaces between seeds are covered with herbicides to which row crops are sensitive. This provides for extermination of weeds. To intensify the growth of plants, seeds are secured on band together with regulators of growth and development of plants. EFFECT: improved design and higher efficiency. 2 cl

Description

 The invention relates to agriculture, namely to sowing plants using sowing tape.

 Sowing tapes are known, which are strips or ropes of various thicknesses from different biodegradable or water-soluble materials (water-soluble resin, paper, fabric, grass fibrous material, regenerated cellulose), on which seeds are fixed. These seed tapes may contain fertilizers, growth substances, fungicides, bactericides, insecticides, herbicides.

 However, these tapes do not provide weed control or this fight is not effective enough.

 Closest to the proposed solution for the achieved result and technical essence is a ribbon for sowing seeds contains strip material with seeds, fertilizers and herbicides attached to it. Herbicides inhibit and destroy weeds in rows, and fertilizers enhance the growth of cultivated plants. In the aisles, weeds are destroyed by cultivation.

 However, when seed seeds germinate, young plants absorb herbicides. This creates the need to use only non-herbicides that do not inhibit or slightly inhibit seeded plants at all phases of their development. This circumstance does not allow the use of herbicides that are potent on weeds if they are highly toxic to planted cultivated plants. The tape does not provide a highly effective weed control.

 The purpose of the invention: improving the effectiveness of weed control.

This goal is achieved by the fact that successively different herbicides are applied to the seed tape: in the places where the seeds are fixed, herbicides are applied that do not inhibit or slightly inhibit the sown cultivated plants, and other herbicides that are potent in weeds are applied between the seeds. In between, you can use herbicides that are highly toxic to seeded crops in the early phases of their development. These herbicides are applied to the tape at distances from seeds that prevent them from inhibiting cultivated plants in the early stages of development of the latter. Low toxic herbicides in places attached to the seed tape act on weeds and crops as usual. Strong herbicides applied between the seeds strongly inhibit or destroy weeds, but they do not act on cultivated plants grown from sown seeds because they are at a distance from them. In the early stages of development, cultivated plants do not contact potent, highly toxic herbicides. At later stages of development, the plant grows and can absorb highly toxic herbicides. However, this does not depress plants so much for the following reasons:
firstly, herbicides are depressingly weaker on large plants than on seedlings and young plants;
secondly, in the process of growth, cultivated plants can arrange their roots so that they take up less herbicides, i.e. locate, orient their roots in places of sowing seeds and in row-spacings (the phenomenon of negative chemotropism);
thirdly, over time, the herbicides themselves are destroyed or evaporated.

 Distinctive features of the invention are: different herbicides are applied to the seed tape: low-toxic herbicides for cultivated plants growing from seeds fixed on the seed tape are applied at the places where the seeds are attached, and herbicides that are highly toxic to weeds, including highly toxic for the seeded, are applied in the spaces between the seeds cultivated plants, the application of highly toxic herbicides is carried out at a distance from the seeds, which prevents the inhibition of plants in the early stages of development of the latter. The combination of distinctive features meets the criteria of the invention of "novelty."

 Fertilizers and growth regulators contribute to the rapid growth of cultivated plants and thereby reduce the inhibitory effect of toxic herbicides and weeds on them.

 PRI me R. A braided cotton rope is used in which corn seeds are woven at a distance of 25 cm from each other. In the places where seeds are fixed, the rope is saturated with atrazine at a distance of 5 cm from the seeds in both directions. To enhance the growth of corn in the same places applied phosphorus-potassium-nitrogen fertilizers with the addition of trace elements. At a distance of more than 5 cm from each seed, linuron, a potent corn seedlings herbicide, was applied. The tape is stretched in the field and buried in a furrow. After a few days, the corn seeds germinate. Corn sprouts are resistant to atrazine (7, p. 183). Selective action of the herbicide against weeds can lead to the fact that only weeds resistant to atrazine, for example, humai, will survive close to the seed of the corn. Only weeds that are resistant to it will survive in the place of contact with linuron, for example, wheat grass, cirsium, field bindweed. In a row near the sprouts of corn themselves and in the distance from them different weeds will grow, which will mutually oppress each other. As a result, they will do less damage to corn than would the same amount of the same weed plants. As the corn grows, its roots go into the area of linuron herbicide, to which the corn is moderately susceptible. But a large adult plant, this herbicide will not be able to strongly oppress. In addition, corn can, under the influence of negative chemotropism, locate its roots with the least capture of linuron (predominant root growth in the rows between rows free of weeds as a result of mechanized weeding).

 As a result of the use of the proposed technical solution, it becomes possible to use a wider range of herbicides, including toxic ones for sown cultivated plants, over a considerable area of the row. In addition, the use of different herbicides can lead to competition and mutual oppression of the surviving weeds, and this will further reduce their oppression of corn. As a result, there is an increase in the effectiveness of weed control.
