摘要: 为解决葡萄根系上浮和土壤酸化问题,探明葡萄园生草对葡萄根系生长和土壤营养状况的影响,以清耕为对照,在辽宁兴城地区葡萄园行内种植黑麦草(Lp)和紫花苜蓿(Ms),研究行内生草对葡萄不同根层根系长度和表面积、土壤有机质及矿质元素含量的影响。结果表明,黑麦草和紫花苜蓿均较清耕显著提高不同时期和不同土层的根系长度和根系表面积(P< 0.05),且其增幅为黑麦草 > 紫花苜蓿 > 清耕。黑麦草具有减轻葡萄园土壤酸化的效果,其土壤pH值6.22~7.04,高于清耕的6.14~6.39。黑麦草在坐果期、转色期和收获期的土壤有机质含量较清耕分别显著提高了24.71%,48.07%和44.44%(P< 0.05),而紫花苜蓿较对照分别提高了7.87%,29.88%和34.07%。黑麦草在坐果期、转色期和收获期时土壤中碱解氮含量较清耕分别显著提高了40.40%,51.46%,22.15%(P< 0.05),而紫花苜蓿较清耕分别提高了29.88%,28.03%,5.42%。黑麦草和紫花苜蓿较清耕均显著提高了各个时期的土壤有效磷含量(P< 0.05),钾元素含量明显升高,黑麦草处理的土壤全钾、全磷和有效磷含量最高,其次是紫花苜蓿,清耕最低。综上,行内种植黑麦草对增加葡萄根系长度和根系表面积、提高土壤有机质含量、减轻土壤酸化、增加必需营养元素含量等方面效果优于紫花苜蓿和清耕。

Abstract: To solve the problem of grape root uplift and soil acidification,the influences in root growth and soil properties were studied by planting Lolium perenne L.and Medicago sativa L.in the inline of vineyard located at Xingcheng in Liaoning Province.The results showed that both Lp and Ms could significantly increase the root length and surface area in different stages and root levels (P< 0.05), and the amplification of which from high to low was Lp,Ms and control.The soil in vineyard by control management had an acidification trend,the pH distributed from 6.14 to 6.39.The pH ranged between 6.22 and 7.04 in Lp treatment,while that in Ms treatment was lower than Lp treatment.Compared with the control,the content of organic matter in Lp treatment significantly increased by 24.71%,48.07% and 44.44% (P< 0.05),while the Ms treatment increased by 7.87%,29.88% and 34.07%,respectively.In fruiting period,veraison and harvest time,the content of alkaline nitrogen in soil by Lp treatment increased by 40.40%,51.46% and 22.15% (P< 0.05) to the control,respectively. In fruiting period,veraison and harvest time,while those in the Ms treatment increased by 29.88%,28.03% and 5.42%,respectively.Compared with the control,both Lp and Ms treatments significantly increased the content of available phosphorus in soil (P< 0.05),which in Lp treatment was the highest,followed by the Ms treatment and the control.Both Lp and Ms treatments could cause the content of each mineral elements significantly increased at a certain time (P< 0.05).The overall effect of Lp treatment on the root length,root surface area of grape,and the content of organic matter,essential nutrients in soil was better than that of Ms treatment and control.
