(54) METHOD FOR PRE-SOURCE TREATMENT OF COTTON SEEDS

(57) The invention relates to the field of agriculture. The purpose of the invention is to increase the field germination of seed and yield and improve the quality of raw cotton. Cotton seeds are soaked in an aqueous suspension of the preparation at a pH of 8-9 for 7-8 hours for lowered seeds and 3-4 hours for bare seeds. Suspension of the drug contains, wt%: sulfur 20-30; sulfanol 0.6-0.7; carboxymethylcellulose 0.08-0.15; water - the rest. When sowing the treated seeds, 100% bloom occurs 5-6 days earlier than in the control; the mass of the raw box of the lower russa exceeds the control by 1.5 g, the average rusa by 10.5 g, the upper rusa by 0.9 g. 6 tab.

The invention relates to agriculture and can be used for pre-sowing treatment of seeds, mainly cotton.

The purpose of the invention is to increase the field germination of seed and yield and improve the quality of raw cotton.

An example. The working fluid was prepared according to the following scheme: one day prior to treatment, carboxymethylcellulose (CMC) was dissolved in warm water, then sulfanol was added to this solution and ground sulfur purified from mechanical impurities was added to the prepared mixture with uninterrupted stirring. The pH of the solution was adjusted with alkali. Omitted seeds were soaked in a preparation with a pH of 8 for 8 hours.

Before laying the experiments, the infection rate of the drink and their verges by gnawing and sucking pests, as well as the number of entomophages was determined.

Seed germination was found in periods of single and mass sprouting, plant density was found after thinning at the beginning of budding, during fruit formation by 25 samples in 10 meters of each repetition.

Accounting for the number of insects was carried out from the appearance of seedlings to budding every five days.

On the 11th day after sowing the seeds soaked in the proposed preparation, a 100% emergence of seedlings was obtained, whereas in the control only 72.2% had risen, and in the standard 81.4%.

Visual observations of the dynamics of the emergence of shoots show that pre-sowing the soaking of seeds in the proposed preparation at pH 8–9 contributes to obtaining early yields. When the seeds are ground on the proposed method, seedlings appear A-5 days earlier than with the seed of dry seeds.

The presowing seed soaking according to the proposed method does not affect CNaiB seed treaters. This is due to the presence of SC in the working fluid, sulfur sticks and remains on the surface of the seeds. Subsequently, after entering the soil, sulfur is converted into a form of food available to plants.

from the pH of the liquid with an average content of the components shown in the table. one.

Seeds bare seeds were soaked for 3-4 hours, and lowered seeds - for 7-8 hours.

Due to the intensive growth of plants, mass flowering and filling of fruit elements is accelerating. When sowing seeds treated by the proposed method, 100% flowering was obtained 5-6 days earlier than in the control and standard. Early flowering contributed to the rapid accumulation of boxes.

In tab. Figure 2 shows the effect of seed treatment on boll size and fiber yield. According to the table. 2 that in the method proposed the weight of the boxes is different in rusam. For example, when processing the seed, the weight of the raw of the lower russeted box exceeds the control by 1.5 g, the average, by 0.5 g, the upper, by 0.9 g. Wetting the seeds with water does not affect the weight of the raw box and remains at the level of control, although the number of boxes slightly ahead of the control option.

The effect of the method of pre-sowing seed treatment on yield is shown in Table. 3

The effect of the method of pre-sowing treatment of cotton seeds on the dynamics of the number of pests and entomophages on cotton (per 100 leaves) is shown in Table. four.

The dependence of indicators on the content of components in the preparation at pH 8.5 is presented in Table. five.

Numerous experiments show that optimal results are obtained with the following content of components in the preparation, wt.%: Sulfur 20-30; sulfanol 0.6-0.7; CMC 0.08-0.015%; water - the rest. With a lower content, the indices decrease, with a larger one, they stabilize or decrease.

The dependence of the results on the time of soaking the seeds is presented in Table. 6. The most expedient is to soak the dipped seeds for 7-8 hours, bare - for 3-4 hours. With a shorter time, the indices drop dramatically, with a higher rate they stabilize or even decrease due to the fact that the enlarged seedlings damage the sowing seedlings. hardware.
