Система удобрений кабачка на аллювиально-луговых почвах Московской области

Abstract

The results of studies on the fertilizer system of zucchini on alluvial-meadow soils of the Moscow Region are discussed. The fertilizer system of zucchini (Belogor F1 hybrid,) consisting of the application of N90P90K120 and zeolite (0.4 t ha) prior to cultivation increased fruit yield by 42.9%. The application of N90P90K120 + Tenso Cocktail increased the yield by 39.4% at LSD05 (least significant difference) = 1.7 t ha and LSD05 for fertilizers = 1.3 t ha. The application of N90P90K120 + zeolite and N90P90K120 + Tenso Cocktail increased dry solids in zucchini fruits by 3.4-5.1%; the application of N90P90K120 + Tenso Cocktail increased vitamin C content by 33.3%; N90P90K120 + zeolite increased monosaccharides by 7.8%; N90P90K120 + Humistar + Tenso Cocktail increased the total sugars by 18.5% compared to the control. The minimum nitrate content in the fruits was revealed in the fertilization variant N90P90K120 + Zircon (378 mg kg), and maximum content in N90P90 variant (660 mg kg). The nitrate content in the variant N90P90K120 + Tenso Cocktail was at the level of maximum allowable concentration, making 400 mg kg.

Приведены результаты исследований системы удобрения кабачка на аллювиально-луговых почвах Московской области. Система удобрения кабачка гибрида Белогор F1, состоящая из внесения под культивацию N90P90K120 и цеолита нормой 0,4 т/га, обеспечила прибавку урожая плодов на 42,9%. N90P90K120 + Тенсо-коктейль дала прибавку урожая на 39,4% при НСР05 = 1,7 т/га и НСР05 для удобрений = 1,3 т/га. N90P90K120 + цеолит и 90P90K120 + Тенсо-коктейль способствовали повышению сухих веществ в плодах кабачка на 3,4-5,1%, N90P90K120 + Тенсо-коктейль витамина С на 33,3%, N90P90K120 + цеолит моносахаров на 7,8%, N90P90K120 + гумистар + Тенсо-коктейль суммы сахаров на 18,5% по сравнению с контролем. Минимальное содержание нитратов в плодах отмечено в варианте N90P90K120 + циркон (378 мг/кг), максимальное при N90P90 (660 мг/кг). В варианте N90P90K120 + Тенсо-коктейль содержание нитратов оказалось на уровне ПДК 400 мг/кг.
