Effect of Three Moisture Conservation Measure Methods  and Drip Irrigation on Dynamics of Mineral Nutrition Elements in Ziziphus jujuba Mill. cultivar  'Linyilizao Leaves

Abstract:   To investigate the effect of moisture conservation  methods and drip irrigation on dynamics of mineral nutrition elements of Ziziphus jujuba Mill. cultivar  ¡®Linyilizao¡¯ (¡®Linyilizao¡¯) leaves, an experiment was conducted in loess hilly regions. The seasonal dynamic changes of nine nutrition elements (including N, P, K, Ca, Mg, Cu, Mn, Zn and Fe) of ¡®Linyilizao¡¯ leaves in six treatments were examined. The results showed that: the contents of N¡¢P¡¢K¡¢Mg¡¢Mn and Cu elements were improved in drip irrigation treatment. The contents of P, K, Mn, Cu and Zn as well the yield of ¡®Linyilizao¡¯ were lowest in the control of straw mulching treatment, straw mulching treatment significantly increased the above-mentioned mineral element contents and yield. With the exception of Mg element, the contents of remaining elements were relatively high in fish-scale treatment. The similar dynamics of mineral elements were observed in different treatments,  in the growth period, N, P and, K contents showed a trend of decrease while Ca, Mn contents were increase; Mg content rised to a stable level, then experience fell; Zn and Cu contents showed a trend of fluctuating. Fe content increased and then decreased. Accumulation of mineral elements in leaves showed a synergistic or antagonism effect, different soil conservation methods and drip irrigation changed the correlation degree between the elements. The order of ¡®Linyilizao¡¯ yield in different treatments was found to be drip irrigation over control of drip irrigation>straw mulching>fish-scale>control of straw mulching>control of fish-scale, the yield of treatments drip irrigation was increased from 47.47% to 143.67% than other treatments.

Abstract:   In this work 8 years old dwarf and compactly planted mountain Ziziphus jujuba Mill. cultivar  ¡®Linyilizao¡¯ was used as experimental object and field experiments are combined with lab analyses.  For different measures  such as drip irrigation, straw coverage and scale ripples, The seasonal dynamic changes of nine nutrition elements (including N, P, K, Ca, Mg, Cu, Mn, Zn and Fe) of ¡®Linyilizao¡¯ leaves , due to combined application of N, P, K elements in years, have been studied. The results showed that the contents of N, P, K, Mg, Mn and Cu elements were enhanced with drip irrigation treatment. The contents of P, K, Mn, Cu and Zn as well the yield of ¡®Linyilizao¡¯ were lowest in the control of straw mulching treatment, which significantly increased the above-mentioned mineral element contents and yield. With the exception of Mg element, the contents of the remaining elements were relatively high in fish-scale treatment. Similar dynamics of mineral elements were observed under different treatments and N, P and, K contents showed a trend of decrease while Ca, Mn contents were increasing. Mg content first rose to a stable level and then fell, leveling off stably. Zn and Cu contents fluctuated and Fe content first increased and then decreased. Accumulation of mineral elements in leaves showed a synergistic or antagonism effect and different soil conservation methods and drip irrigation changed the degree of correlation among the elements. The descending order of ¡®Linyilizao¡¯ yields for different treatments was found to be 1) drip irrigation 2) controlled drip irrigation 3) straw mulching 4) fish-scale 5) controlled straw mulching 6) controlled fish-scale. The yield of drip irrigation treatments  was increased from 47.47% to 143.67% compared with other treatments.
