Abstract

The invention is intended for the chemicalization of agricultural production. The purpose of the invention is to increase the yield of cereal crops. By applying liquid manure in combination with mineral nitrogen and a herbicide, yield increases are achieved. The magnitude of the dose of the liquid manure is due to the safe concentration that ensures the absence of burns and the formation of a thick film from the non-root application of the liquid manure. The action of physiologically active substances of slurry in combination with the factor of applying the mixture at certain phases of the growth of cereal grains under the condition of foliar feeding causes the effect to be achieved. The invention opens up yet another method for using manure. 1 tab.

Description

This invention relates to the chemicalization of agricultural production.

The purpose of the invention is to increase the yield.

Example. In the tillering stage of cereals, for foliar feeding of plants and weeds, a solution in the volume of 600-1000 l / ha containing a liquid fraction of a liquid-free manure diluted with water, mineral nitrogen and herbicide is used in the following ratio of components, wt.%:

Bottled manure 10.00-12.50 Mineral nitrogen1.00-1.50

Herbicide 2,4-D0,07-0,10

WaterEverything

The working solution is brought into the field by tankers. The treatment of the crops was carried out using a sprayer sprayer, in which the diameter of the nozzles of the nozzles is increased 1.3 times. Spraying can be carried out by the fertilizer with PZhU-9 liquid fertilizers.

Similarly, a working solution is prepared and foliar feeding is carried out at the beginning of the vykolashivan phase. In the presence of plant diseases, the hectare rate of the corresponding fungicide is introduced into the solution instead of the herbicide.

The effect of the mixture is due to a combination of the factors of the phase of use of the mixture, the presence of physiologically active substances in liquid manure, including auxins, the action of the substances used on the leaf plate, as well as the nitrogen / manure / pesticide combination.

The effect of the mixture is illustrated by the results of experiments with wheat and oats given in the table, where Ie. - trace elements: in the tillering stage - MnSO4 0.05%; in the outgrowth phase - boric acid 0.05%; W.N. - liquid cattle manure 10-12.5% coat of arms. - herbicide octanone 0.8 kg / ha ae .; fung. - fungicide zineb 3 kg / ha a.v.
