THE EFFECT OF A BIOLOGICAL DRUG ON THE GROWTH AND DEVELOPMENT OF GRASS MIXTURES DURING THE RESTORATION OF PASTURE LANDS

Abstract

Widely zoned speciesof forage grasses in Kazakhstan are Sudan grass, sorghum and mogar. Due to their biological characteristics, they can germinate and grow in a dry-steppe region. The biological feature of the selected herb mixture is its deep root system. Therefore, in order to study resource-saving technologies and restore degraded pastures, seeds of herbaceous communities (Sudanese grass, sorghum and mogar) and the biological preparation "Tumat" were taken for further small-scale farming experience According to the results of the work carried out, it was found that before the experiment was laid, in the spring, the salinity of the soil by degree belongs to the neutral type of salinity (pH<8.5). The pH value of the soil for the cultivation of fodder crops is optimal. According to the humus content in the humus horizon (0.88-1.15), they are low-humus by grouping. Prior to the experiment, the amount of nitrogen in the soil ranged from 36.4 to 47.6 mg/kg, that is, there is no high demand for nitrogen fertilizers for plants, respectively. The content of mobile forms of phosphorus according to Machigin is low, and the content of K2O in the soil is from 120 to 150 mg / kg, according to Machigin, the average and the need for fertilizer is also average. According to the results of phenological observations, it was revealed that the phase of development of grain fodder crops in variants with spraying of the biological product 1 time was from germination to tillering 15-16 days. In variants without the use of biofertilizer, it takes 17-18 days. The phase of development of legume fodder crops in variants with spraying of the biological product 1 time from germination to the beginning of branching was 17-18 days. In variants without the use of biofertilizer is 19-20 days. The seeds of the sweet clover, compared with alfalfa, rose a day or two later, since it is a solid seed crop.
