Abstract

The invention relates to cotton. The aim of the invention is to increase the processing efficiency, ensure accelerated and high-quality maturation of cotton and improve the state of the environment. A mechanical undercut is performed when opening one or two cotton bolls on a bush along its lateral roots with the introduction of chemical preparations into the undercut zone: non-toxic preparations are applied to the surface of the undercut assembly — first rus, and toxic preparations are inserted inside the undercut assembly, followed by his heading - the second Russian. The invention allows to increase the yield of raw cotton.

The invention relates to the agricultural production of tilled crops, in particular to cotton growing, and can be applied in mechanized cotton growing as a pre-harvest tilled crop of cotton.

The aim of the invention is to increase the processing efficiency, ensure accelerated and high-quality maturation of cotton and improve the state of the environment.

Fig. 1 shows a cotton bush in the opening stage of the first cotton boll; Fig 2 is a diagram of trimming the bush with the introduction of non-toxic drugs to the surface of the alignment; in fig. 3 - the same, with the introduction in the target of the undercut of chemicals with subsequent logging of the target.

Bush 1 of cotton with root system 2 and its lateral roots 3 are placed on ridge 4 in the opening stage of the first cotton box 5 if there are undisclosed boxes 6 on the crown, unripe fruit elements and leaves 7 C on both sides of the bush 1 along the ridge the upper recessed wedge-shaped part 8 and the recessed part 9. Non-toxic preparations 10 are brought onto the surface of the alignment, toxic preparations 11 are inserted into the alignment, followed by sealing by a layer 12 of soil. The operation is performed, for example, by a tilled cultivator — a plant feeder (not shown).

The side roots 3 are trimmed at the stage of opening the first cotton box 5. Undercutting on the ridge 4 from two sides of the bush are formed undercut sections, in the upper part 8 of which nontoxic preparations 10 are simultaneously introduced, creating the effect of drying roots and simultaneously combining the functions of soil fertilizer Usually applied during wintering with beech plowing

By pruning, a plant is brought into a state of stress, which increases the root-drying effect from the moment of stress, the plant mobilizes its entire energy potential and biological resources for the accelerated maturation of fruit elements 6 with the intensification of photosynthesis through leaf 7.

On the 10-15th day after the treatment, moisture deficiency occurs, by this moment the leaves give up their entire biological reserve to the mobilization process and cease to live - the intensive wilting and falling off of the leaves begins. At the same time, as Experiments show, a 70-80% opening of the bolls is achieved (with defoliation 40-60%, with natural aging 15-25% opening) and one can proceed to the first machine failure of cotton.

Danee. after 10–12 days, the leaf fall off justifies 80% and the opening of the bolls 100% (with defoliation 70–80%, with natural maturity 40–50%), the remaining crop is harvested.

Thus, using the proposed method, it is possible to achieve accelerated ripening and cotton harvesting from the moment of opening the first boll for 10-15 days (with defoliation for 20-25 days, with natural ripening for 35-40 days).

When applied simultaneously with the trimming of toxic drugs inside the trunk into the recessed part 9, the cross-section of the ground is covered with soil layer 12 to isolate and prevent contact of toxic substances with the environment.

The preparation 11 can have the most varied useful purpose: to improve the process of maturing the harvest of fruit elements b, to destroy the pigment substances in the leaves before the machine gathering, to help obtain a non-fragile, elastic structure of the leaves 7 machines, untheated and untreated

weed cotton with small litter). Such an action has, for example, the defoliant butythos.

When the defoliant is introduced by the proposed method, its consumption can be reduced by a factor of 10, while the environment is environmentally friendly, since in the soil the butifos is destroyed within 3-6 hours. Fall on the notches of the side roots 3, the preparation penetrates into the structure of the bush, striking it , no damage to the fruit elements 6, as is the case with defoliation of magnesium chlorate.

Compositions of the preparations introduced into the bush simultaneously with trimming the lateral roots can be programmed and controlled by the process of maturing the crop, achieving various positive effects taking into account various factors (climatic, biological, technological).

Thus, the proposed method of pre-harvest processing of cotton due to the biological improvement of the aging process implies an increase in cotton yield by 30% and an improvement in the quality indicators of raw cotton and seeds (defoliation speeds up the opening, rather than the aging of cotton, due to non-aging of natural yield) 50% yield).

Claims (1)

Invention Formula The pre-harvesting method of a cotton cultivator, including its mechanical undercut with the introduction of chemicals and the soil intake, characterized in that, in order to improve processing efficiency, ensure accelerated and high-quality maturation of cotton and improve the state of the environment, the mechanical undercut is performed with disclosing one or two bolls of cotton on a bush along its lateral roots with the introduction of chemical preparations into the undercut zone: nontoxic preparations are applied to the surface of the undercut section - first the second rus, and the toxic drugs are introduced into the inside of the section of the undercut with its subsequent encrustation — the second rus.
