A comparative analysis with the prototype is to conclude that we offer a small mixture that differs from the known introduction of a new component aj h, including calcium.

/ | "Apis of known standard mixtures used for growing plants c). -hp Che culture 1, shows that they are g--. fjf one by one and those properties that are simply offered are soldered; a significant improvement in the nitrogen nutrition of wheat due to the introduction of calcium nitrate and, as a result, an increase in the protein content in the grain and an improvement in the growth conditions.

For experimental verification, a standard Prishnikov nutrient mixture and the proposed mixture were prepared (see table 1).

Mixtures were prepared by simply mixing each component with sand. Spring wheat was grown in a vegetation house with a roof made of a plastic film in vessels (six plants each) containing 5 kg of sand and 0.5 kg of polyethylene granules as drainage. After elutriation, quartz sand was washed with 20% HCI, tap water and distillate. Nutrient mixtures were taken out once before sowing. The content of total nitrogen in the grain was determined by the Kjeldahl method, and the protein by multiplying the total nitrogen by a factor of 5.7. The results of the experiments are presented in table.2. Their mathematical processing was carried out according to Dospehov.

From the data of Table 2 it follows that in wheat varieties with low productivity (Cesium II), an increase in the content of nitrogen and protein in the grain on the proposed mixture occurs already

with a calcium nitrate content of 0.775 g / kg sand. In this case, grain yield may not increase if it is limited by the variety's capabilities. Increasing the dose of calcium nitrate in the proposed mixture to 1.11 g / kg of sand does not affect the yield and total nitrogen content in the grain of low-yielding wheat. When growing wheat varieties with high productivity (Omsk 17), the proposed mixture increases the yield due to improved nitrogen nutrition conditions. grain and its protein content. When the concentration of calcium nitrate in the proposed mixture is 1.11 g / kg of grain per day, the grain yield does not increase, but the protein content in the grain increases to 16.6%, which indicates more favorable conditions for the nitrogen nutrition of wheat in the proposed mixture, than at 0 standard

Using the present invention, it is possible to optimize the conditions of mineral nutrition of wheat when it is grown in a sand culture and to obtain 5 grains with a high (14.6-17.7%) protein content

The optimal nutrition of wheat when growing it in an artificial environment is a prerequisite for the study of physiological and biochemical processes in plants, their resistance to diseases and adverse environmental factors, in order to assess the productivity of varieties, to obtain complete seeds, which is especially important 5 in breeding selection.
