石灰性土壤施镁对葡萄产量和品质的影响
The effect of magnesium application in calcareous soil on grape yield and quality
摘要
Abstract
To investigate the effects of magnesium fertilizer application on grape yield and quality in calcareous soils,a two-year field experiment was conducted in Shihezi region using two grape varieties of'Red Globe'and'Ugni Blanc'.Four magnesium oxide(MgO)fertilizer application rates were established:MgO 0 kg/hm2(S0),7.5 kg/hm2(S7.5),15 kg/hm2(S15),and 30 kg/hm2(S30).The experimental results demonstrated that over the two-year period,both cultivars exhibited significant yield increases with rising magnesium application levels.The yield increments ranged from 7.85%-21.94%for'Red Globe'and 4.71%-25.20%for'Ugni Blanc'compared to the control treatment(S0)(P<0.05).For'Red Globe'grapes,critical quality parameters including soluble solids content,soluble sugar content,skin hardness,flesh hardness,and sugar-to-acid ratio initially increased then decreased with magnesium application,showing significant differences compared to S0(P<0.05).Titratable acidity displayed an inverse trend,initially decreasing before rising.Moderate magnesium application enhanced fruit color characteristics,increased the brightness(L* value by 4.3%)and red chroma(a* value by 6.7%).Quadratic regression model analysis revealed optimal MgO application ranges of MgO being 18.13-23.14 kg/hm2 for'Red Globe'and 17.55-17.75 kg/hm2 for'Ugni Blanc'in this calcareous soil region.These findings provided scientific references for magnesium fertilizer management in viticulture practices within Xinjiang's calcareous soil areas.关键词
