【摘要】：【目的】研究葡萄黄化园土壤养分与地上部的关系。【方法】以吐鲁番市主栽品种无核白和无核白鸡心为材料,采集正常和黄化园不同深度土壤样品进行营养诊断分析,筛选影响枝叶生长及果实产量的主要土壤因子。【结果】正常株和黄化株土壤总盐量、有机质、速效N、速效P、速效K和有效Fe含量间存在显著差异;黄化株新梢节间长、叶重、单叶厚及产量均显著低于正常株,且无核白黄化株分别是正常株的1.30、1.38、1.35和2.15倍。无核白黄化株新梢节间粗与有效Fe含量呈显著正相关,无核白鸡心黄化株叶重、叶长及叶宽与有效Fe含量呈显著正相关,相关系数分别为0.726、0.902、0.691。无核白黄化株产量与速效K呈显著负相关,相关系数为-0.164。【结论】吐鲁番胜金乡土壤pH值、K含量较高及有效Fe含量较低是引起葡萄黄化的主要原因。
[Abstract]:[objective] to study the relationship between soil nutrients and aboveground part of grape yellow orchard. [methods] the soil samples of normal and yellow garden were collected and analyzed with denuclearization and denuclearized chicken hearts as materials. [results] there were significant differences in soil total salt content, organic matter, available N, available P, available K and available Fe contents between normal and yellow plants. The thickness and yield of single leaf were significantly lower than those of normal plants, and the denuclearized yellow plants were 1.300.38 1.35 and 2.15 times higher than those of normal ones, respectively. There was a significant positive correlation between the internode thickness and the available Fe content in the new shoot of the non-nuclear white yellow strain, and a significant positive correlation between the effective Fe content and the Ye Zhong, leaf length and leaf width of the non-nuclear white chicken heart-yellow strain, with correlation coefficients of 0.726 ~ (0.902) ~ (0.902) ~ (0.691), respectively. There was a significant negative correlation between the yield of denuclearized yellow plants and available K, the correlation coefficient was -0.164. [conclusion] the higher pH value of K and the lower content of available Fe in soil of Shengjin Township in Turpan were the main causes of grape yellowing.
