摘要
针对贺兰山东麓酿酒葡萄栽培中存在的大水沟灌水分利用率低,产量低而不稳及果实品质差等问题,采用田间试验研究传统沟灌和不同的滴灌灌水量对酿酒葡萄长势及产量和品质。结果显示:滴灌处理下酿酒葡萄的新稍长增加,以双管滴灌处理新梢最长;滴灌处理下百叶鲜重显著高于沟灌处理,双管滴灌处理下百叶鲜重进一步显著高于单管滴灌;滴灌有促进叶片全氮累积的趋势,与沟灌相比,叶片全氮显著提高;双管滴灌处理能显著增加果实可溶性固形物及可溶性糖含量;单管滴灌处理能降低果实的总酸度,增加糖酸比;单管滴灌与双管滴灌对产量有明显的增加作用,与沟灌达到显著水平。
In the eastern foot of Helan Mountain, the grape planting has the problems of low water use efficiency of flood irrigation, low and unstable production and poor fruit quality. The field experiments are conducted with traditional furrow irrigation and drip ir- rigation with different water quantity and the growth, yield and quality of wine grape under each treatment are measured. The results show that the length of new shoot increases under drip irrigation and that under double tube drip irrigation is the longest; the fresh weight under drip irrigation is significantly higher than that under furrow irrigation; the fresh weight under double tube drip irrigation is further significantly higher than that under single tube drip irrigation; drip irrigation has a trend to accumulate leaf total nitro- gen and, leaf total nitrogen significantly improves when compared to furrow irrigation; Double tube drip irrigation can significantly increase fruit soluble solid content material and the soluble sugar content; Single tube drip irrigation processing can reduce total acid- ity of fruit and increase sugar acid ratio; both Single and double-drip irrigation have significant increase on yield compared with furrow irrigation.
