Description

The invention relates to the field of agriculture, in particular to a technology for growing tobacco.

The survival rate and the rate of rooting of seedlings in the field, depending on the method of planting, largely determine the yield of any transplant crop, including tobacco.

For better survival and rooting of plants, tobacco seedlings are planted in moist soil.

A known method of planting tobacco seedlings with moistening the soil by letting water through the furrows (Recommendations on the technology of tobacco cultivation. Tashkent, 1987).

The most widespread, as a more rational, method of planting tobacco seedlings with portioned moistening of the soil was received: with the addition of water separately for each plant (usually 0.5 l per plant) - Leonov I.P., Petrenko A.G., Psarev G.M. Textbook tobacco grower. - M .: Agropromizdat, 1986.

The disadvantage of this method of planting tobacco with water (taken by us as a prototype) is that it does not provide the desired survival rate and rate of rooting of plants. Often encountered in practice, the death of a part of transplanted plants and a delay in rooting (especially due to unfavorable external factors) leads to sparse plantations, plant disease, weed suppression, and ultimately a decrease in crop yields.

The technical solution to the problem is to increase the efficiency of the method of planting tobacco seedlings by providing faster recovery of the physiological functions of plants disturbed during planting.

The objective is achieved by the fact that when planting tobacco seedlings under each plant, an aqueous solution of potassium hydroxide is added in a concentration of 0.01-0.50% at the rate of 0.5 l of solution per plant.

The novelty of the proposed proposal is due to the fact that as a result of the introduction of potassium hydroxide into the soil — into the root zone in the roots, the level of plastic substances is faster to achieve the formation and enhanced growth of new roots, which leads to an increase in the percentage of established plants, a reduction in the period of their rooting and - increase tobacco productivity.

It has been experimentally established that potassium hydroxide concentrations below 0.01% are not effective, above 0.50% they cause inhibition of transplanted seedlings in the field.

According to the patent and scientific and technical literature, no similar technical solution was found, which gives reason to judge the inventive step of the proposed solution.

Since the invention uses a simple, generally accessible inorganic compound, it is possible to widely use it in tobacco growing.

An example of a specific use of the method.

When planting tobacco in the field, instead of irrigation water, a 0.01-0.50% aqueous solution of potassium hydroxide is used, which is applied at the rate of 0.5 l per plant.

The results of using the new method of planting tobacco seedlings in 2002 at the experimental breeding site of the All-Russian Research Institute of Tobacco and Tobacco Products are shown in the table.
