METHOD OF SELECTING GRAIN CROPS FOR SOWING ON SPECIFIC SOILS

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of agriculture, in particular to agriculture and crop production. Method comprises successive stages: the formation of at least two prototypes of seeds of different grain crops or different varieties of grain crops and at least two control samples of the corresponding seeds, ensuring the contact of test samples of seeds with soil with the addition of water to achieve the lowest moisture capacity of the soil; ensuring the contact of control samples of seeds with sand with the addition of water to achieve the lowest capacity of the sand; extracting the indicated test and control samples of seeds before germination, removing soil and sand from germinated seeds and placing the treated experimental and control samples of germinated seeds in identical transparent containers with water, compaction of germinated seeds in containers by means of vibration in the vertical plane, and shock impact on the bottom of the container, while after vibration impact on the seed samples, identical weights are placed in the container, determination of bulk volumes of experimental (V2i) and control (V3i) samples of germinated seeds by the height of the load from the bottom of the tank, determination of the value of the inhibitory effect of the soil on the development of seeds compared to sand for each sample (II) by the formula: II=((V3i-V2i)/(V3i-V1))*100 %, where V1 – the correction factor characterizing the bulk volume of the swollen seeds of cereal grains, germination of which was carried out within 24 hours on the sand; V2i is the bulk volume of germinated seeds of the prototype; V3i is the bulk volume of germinated seeds of the control sample, i is the sequence number of the experimental and corresponding control samples; determining the minimum II, which determine the prototype seed of a grain crop with a minimum amount of inhibition of the soil studied, which characterizes the possibility of obtaining the maximum yield of this grain crop.;EFFECT: method provides the possibility of obtaining maximum yields and increase the speed of assessment.;8 cl, 6 dwg, 3 tbl, 5 ex
