Оценка технологий обработки светло-каштановой почвы в условиях агролесомелиорации

Abstract

Data for study of complex influence of various technologies of light-chestnut soil treatment and of field-protective forestations on serials growth and development are expounded in the paper. It is defined that productive moisture reserves on an inter-stripe cell are distributed unevenly and strongly vary with the remoteness from a forest belt and soil treatment technology. The greatest spring moisture reserve under the conditions of agroforest landscape is formed when treating the soil with combined unit APK-6 in a zone between 5 and 15 H away from field-protective forestation. Accessible moisture amount for 5 years of study on winter wheat sowing area in average is 144 mm, on spring barley 128.6 mm, under the conditions of open agrolandscape 125.1 mm and 108.1 mm correspondingly. Soil microbiological activity increases as approaching to a field-protective forest belt by reason of accessible moisture presence in soil. The greatest activity of soil microorganisms has been noted at 10 H distance from the forest belt. Depending on soil treatment technology it was equal to 23.5-31.72% on a winter wheat sowing area. Cereals yield on the interstripe space depends on the distance from the forest belt and the soil treatment. The use of combined resource-saving technology of soil treatment assures the very high yield of cereal crops under the conditions of both open field and agrolandscape. Increment of yield in the agrolandscape amounted due to the use of the combined unit to 0.13 t/ha on the winter wheat sowing area, 0.10 t/ha on the spring barley sowing area and 0.16 and 0.10 t/ha in the conditions of open field correspondingly.

В статье изложены материалы исследований по комплексному влиянию различных технологий обработки светло-каштановой почвы и полезащитных лесных полос на рост и развитие зерновых культур. Установлено, что запасы продуктивной влаги на межполосной клетке распределены неравномерно и сильно варьируют в зависимости от удаленности от лесной полосы и технологии обработки почвы. Наибольший весенний влагозапас в условиях агролесоландшафта формируется при обработке почвы комбинированным агрегатом АПК-6 в зоне от 5 до 15 Н от ПЗЛП. Исследования микробиологической активности почвы показали, что активность почвенной микробиоты возрастает по мере приближения к полезащитной лесной полосе, что обусловлено наличием доступной влаги в почве. Урожайность зерновых культур на межполосном пространстве находится в зависимости от расстояния от лесной полосы и технологии обработки почвы. Применение комбинированной ресурсосберегающей технологии обработки почвы позволило получить самую высокую урожайность зерновых культур в условиях как открытого поля, так и агролесоландшафта.
