Description

The invention relates to agriculture and can be used to optimize soil conditions when growing agricultural crops,

The purpose of the invention is to increase the yield by reducing the vegetation period of the plants, increasing the moisture retention and the temperature of the soil with the subsequent biodegradation of the resulting coating.

Example. To 15 wt.h., 20% alkaline yeast biomass hydrolyzate (HBDB), previously obtained by cooking the latter in 0.5 and, 30 m.h., NaOH or KOH solution for 2 hours in a water bath at . a pre-prepared 5% aqueous solution of polyvinyl alcohol (PVA), then 27 wt.h. soap stock and 28 ma.ch. water. The resulting mixture is stirred and then neutralized with nitric acid to pH 7.0-7.2.

The resulting composition with a rate of 450 kg / ha using conventional spraying devices is applied in the inter-row spans of rainfed land previously sown with cotton.

The proposed method is experiencing the following mulching compositions.

5 The effect of mulch films on soil condition and cotton development is presented in the table.

In comparison with the known method, the proposed method allows to increase the yield by 4.5 kg / ha, moisture retention by 2.2%, temperature by 1-2 ° C and shorten the growing season by 2-3 days. In addition, the mulch coating in 60-75 days biodegrades, turning 5 into a mineral-organic fertilizer .. The root system of plants is much denser, there are more branches of roots. The number of cotton bolls on bushes with a mulch coating is 3 times greater than 0 on the control.

Claims (1)

Invention Formula The method of soil mulching for crops of agricultural crops, 5 includes applying a water dispersion of organo-mineral mulching material in recommended doses, which is due to the fact that, in order to increase crop yields by shortening the vegetation period of plants, increasing water retention and soil temperature with the subsequent biodegradation of the resulting coating, as a mulching material, use 5 composition containing soap stock, 5% aqueous solution of polyvinyl alcohol, alkaline biomass hydrolyzate yeast minutes and water in the following ratio, wt.%: f. Soapstock7.0-27.0 5% aqueous solution of polyvinyl alcohol10,0-30,0 Alkaline Hydrolneath , biomass of yeast 2,5-15,0 Water Else which is previously neutralized with nitric acid to a pH of 7.0-7.2, and then applied between the rows of crops.
