| Materials and research methods. In our studies, pre-sowing treatment of seeds with NacLee at a dose of 1 liter and Fitop at a dose of 2 ml per ton of rice seeds were carried out, which significantly influenced on the power and survival rate of rice roots. In the experimental variants with Fitop and NacLee, in comparison with the control, the length of the roots increased by 1.5 times. Also, during the growing season of rice, foliar feeding was carried out with these microfertilizers and the drug in the tillering and heading phases of the rice culture in doses of 2 liters of NacLee and 1 ml of Fitop per 1 ha, respectively. Analyzes showed that seed dressing and foliar dressing during the growing season of rice culture with NacLee and Fitop 8.67 had been obtained rice yield in experiments at 89.2 c / ha and 82.4 c / ha respectively.
The field experiment was based on the rice irrigation system of Y. Zhakhaev Kazakh Scientific Research Institute of Rice Cultivation. Sowing of rice was carried out by a selection seeder in an ordinary way, the seeding depth was 2-3 cm. The seeding rate was 7.5 million viable seeds per hectare. The predecessor was a layer of lucerne. This was the fertilizer N45P60K30 kg / ha.d. Irrigation mode was a shortened flooding. Plot area was 50m2, 3-fold replication. Allocation of plots was systematic. Rice kind – Syr Suluy. Seed treatment was carried out immediately before sowing by semi-dry method 1 liter per 3 tons of seeds. Foliar dressing was carried out in the tillering phase of plants with MikroKat Grain Start with a rate of 1 l / ha from a working fluid of 25 l / ha, and in the phase of entering the tube Kelik K + Si with a rate of 1 l / ha from a working fluid of 25 l / ha. The biometric analysis was carried out by selecting 10 plants from each plot of the experiment before harvesting. Crop accounting by harvesting of an accounting plot, followed by threshing and weighing. The obtained results have been evaluated by the method of analysis of variance. жүктеу/скачать 2,01 Mb.
