摘要
针对陕北山地果园的干旱缺水、灌溉条件差等问题,开展了高分子保水剂在陕北山地苹果园的应用技术的研究,为陕北山地果园施用保水剂提供理论依据。以榆林子洲山地果园的9年生‘烟富六号’为试材,设置50、100、150 g/株的3个保水剂处理,穴施在距离树体1 m的两侧处,以不施用保水剂为对照,分析不同用量的保水剂对果园的土壤含水量以及苹果树的生长发育、产量和品质的影响。结果表明,施用保水剂可以提高土壤含水量,促进树体的生长,提高产量和果实品质,研究结果表明,在陕北山地果园中以100 g/株的施用量效果最佳。
Due to the drought,water shortage,and poor irrigation conditions in orchards of mountain area in Northern Shaanxi,the application technology of polymer water-retaining agent was studied to provide a theoretical basis for their use in mountain orchards of northern Shaanxi.In Zizhou county of Yulin,orchards of the mountain area,9-year-old‘Yanfu 6’apple were used as material,and non water-retaining agent was used as control.Three water-retaining treatments,including 50,100,150 g/plant with hole spacing of 1m away from apple tree trucks,were applied to analyze the effects of different doses of polymer water-retaining agent on soil water content in orchard,apple tree growth,yield and quality.Results showed that applying polymer water-retaining agent increased soil water content,promoted tree growth,increased yield and fruit quality.Overall,the best application rate for orchards of mountain area in Northern Shaanxi is the 100 g/plant.
