| description | Background. An effective way to optimize the functioning of agricultural landscapes is the application of the principles of protective afforestation. Forest strips have a multi-criteria positive effect on arable land through the formation of favorable growing conditions, which are necessary to obtain high yields of agricultural plants. Long-term scientific research confirms the positive role of protective forest belts in a number of indicators of the agricultural sphere. However, the study of the influence of forest strips on the work of photosynthetic potential has not yet received due attention, which determined the relevance of the study.
Purpose. To study the reclamation effect of protective forest strips of different designs on the formation of elements of the photosynthetic apparatus of ultra-early potato varieties.
Materials and methods. The objects of the study were five ultra-early varieties (Jewel, Colombo, Riviera, Arizona, Carmen) potatoes growing in the adjacent territories with two and twelve row forest strips located in the Astrakhan and Volgograd regions. The studies were carried out at sites located at a distance from forest plantations equal to the height of the plantation itself (H) -2.5N, 5H, 10H, 15H, 20H, 30H (control) in dynamics according to the phases of development of potato agrocenoses.
Results. Under the reclamation influence of forest strips, regardless of the row and design, the greatest increase in leaf area values during the growing season is observed than in the control. The maximum leaf index index for all potato varieties was observed in the potato flowering phase at an altitude of 5H, and there was also an advance in the rate of formation of the assimilating surface and the intensity of photosynthesis in the zone of influence of forest strips. Mathematical analysis confirms a high degree of correlation between the leaf area, assimilating surface and photosynthetic activity of potato agrocenoses of all varieties and the distance from forest strips. The correlation coefficient was R= 0.91-0.97.
Conclusion. The long-term data obtained confirm the positive effect of forest strips on the functioning of the photosynthetic apparatus of potato agrocenoses. |
