【摘要】：为了探知酿酒葡萄在各个生长时期里对肥水吸收利用规律,从而更好地科学指导酿酒葡萄的肥水管理,本试验以5a生的赤霞珠和霞多丽红、白两种主栽酿酒葡萄品种为供试材料,并利用全自动滴管装置定时定量统一浇灌改良Hoagland's营养液进行培养,研究了各生育期中葡萄的营养生长、果实品质、叶片、叶柄和果实中的十种矿物质元素含量、十种矿物质元素和水分的吸收量的动态变化。结果表明:1.同一时间内,赤霞珠的营养生长比霞多丽的营养生长快,其中变化最大的是新稍长度生长量,赤霞珠新稍长度生长量在35天里超出霞多丽新稍长度生长量1.83cm.2.品种差异对矿物质元素在各器官中的分布没有什么影响。N、P、B元素表现为叶片叶柄、果实;K、Zn元素表现为叶柄叶片、果实:Ca元素表现为叶柄、叶片果实;Cu、Mn、Mg这三种矿物质元素在不同器官中的含量表现为叶柄叶片果实;Fe元素表现为叶片果实叶柄,其中大部分元素在叶片和叶柄中的变化趋势较为相似,包括N、K、Cu、Zn、Fe、Ca;果实中元素变化较为平稳,幅度小。3.从开花期到成熟期,单株葡萄对十种矿物质元素吸收总量按大小排序依次为:①赤霞珠:Ca 47.17g,N 43.60g,K 33.20,P28.03g,Mg 9.87g,Fe 171.20mg,B67.94mg,Mn36.47mg,Zn21.05mg,Cu19.68mg;②霞多丽:Ca45.01g,N40.68g,K31.84g,P26.81g,Mg9.61g,Fe167.48mg,B 63.39mg,Mn32.64mg,Zn18.75mg,Cu16.81mg。4.从开花期到成熟期,单株赤霞珠、霞多丽的吸水规律为:吸水总量为赤霞珠(568.45L/株);霞多丽(547.27L/株);膨大期的吸水量最大:赤霞珠(297.07L/株),占总吸水量的52.56%,霞多丽(292.19L/株),占总吸水量的53.39%;其次是成熟期,接近膨大期的一半量;开花期为最低:赤霞珠(26.74L/株),占总吸水量的4.7%,霞多丽(24.78L/株),占总吸水量的4.53%;幼果期和转色期的吸水量差不多,约占总吸水量的9.82%-12.19%。
[Abstract]:In order to find out the rules of absorption and utilization of fertilizer and water in each growing period of wine grape, and to better guide the management of fertilizer and water of wine grape, this experiment used 5 years old Cabernet Sauvignon and Chardonnay Red. Two main varieties of white wine grape were used as test materials, and the nutrient growth, fruit quality and leaf of grape in different growth stages were studied by using automatic drip device to irrigate the improved Hoagland's nutrient solution. The dynamic changes of ten mineral elements in petiole and fruit, the absorption of ten mineral elements and water. The results showed that the vegetative growth of Cabernet Sauvignon was faster than that of Chardonnay at the same time. Among them, the biggest change is the new slight length increment, The increment of new slightly length of Cabernet Sauvignon exceeded that of Chardonnay in 35 days (1.83cm.2.) the variety difference had no effect on the distribution of mineral elements in various organs. In different organs, the contents of three mineral elements in different organs are: leaf petiole, leaf fruit, leaf petiole, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, leaf stem, The variation trend of most of the elements in leaves and petioles is similar, including the changes of the elements in the fruit, which are stable and small. 3. From flowering stage to mature stage, the change of the elements in fruit is relatively stable. The order of the total absorption of ten mineral elements per grape is: 1 Cabernet Sauvignon: Ca 47.17g / g N 43.60g / kg K 33.20 / P 28.03g / g mg 9.87g / g B67.94mg / g / L Zn _ 21.05mg / g Zn _ 21.05mg / Cu 19.68mg / g ~ (2) Chardonnay: Ca45.01g / N _ 40.68g / L K31.84g P26.81g P26.81g / g mg 9.61g / g Fe 9.61g / g Fe 167.48mg / g B 63.39mg / g mn _ 33.64mg / g Zn 18.75mg Cu16.81mg. 4. from flowering to maturation stage, single Cabernet Sauvignon, Cabernet Sauvignon, Cabernet Sauvignon. The water absorption of Chardonnay is 568.45L / plant, 547.27L / plant; the maximum amount of water absorption is: Cabernet Sauvignon 297.07L / plant, 52.56L / plant; Chardonnay 292.19L / plant, 53.399.The next is maturation. At flowering stage, it was the lowest, which was 26.74L / plant in Cabernet Sauvignon, 4.7L / plant in total water absorption, 24.78L / plant, 4.53% of total water absorption, and 9.82- 12.19m of total water absorption in young fruit stage and color changing stage.
