- Table 1 – The results of accounting for the biological productivity of rice culture when using liquid biological micronutrient fertilizer NacLee and the preparation Fitop 8.67
| Results and discussion. The formation of the yield of cultivated plants to a decisive extent is determined by the productivity of photosynthesis as the main physiological process in the plant organism. The intensity of this process directly depends on the surface area of the leaves, their number and assimilating activity. Studies have shown that the largest leaf area of rice plants, regardless of the dose and method of application of fertilizer Mikrokat grain start and Kelik K + Si was observed in the phase of rice sweeping. Before this phase, the dying off of old leaves and the formation of new ones takes place with the advantage of the second process. After silking, when all the leaves are formed, the assimilation surface is reduced. The use of Mikrokat grain start and Kelik K + Si did not change the nature of the above-noted dynamics, but influenced on the quantitative indicators. So, in the phase of silking in plants from those treated with the drug, the leaf surface was formed more than in the control. Foliar feeding of plants in the phase of tillering and exit into the tube with the drugs Mikrokat Grain Start and Kelik K + Si slowed down leaf dieback, as evidenced by the data of the assimilation surface area in the phase of milky grain ripeness. Comparing the efficiency of foliar feeding with the control, which was not processed, it should be emphasized that the advantage of foliar feeding is confirmed by the formation of the largest assimilation surface of the leaves, accumulation of plastid pigments in them, a decrease in empty grain and an increase in grain weight per plant.

The rice yield under the influence of this biological liquid micronutrient fertilizer and the drug was mainly due to the greater preservation of plants and an increase in productive stalk, an increase in the weight of 1000 seeds, and an increase in the illumination of the panicle. жүктеу/скачать 2,01 Mb.
