摘要
为寻求适宜山区核桃优质高效生产的有效节水措施,以‘清香’核桃为试材,研究不同保水措施对山地核桃园土壤、叶片营养及果实产量品质的影响。结果表明:不同类型保水措施在0~20 cm和20~40 cm土层均有明显保水效果。漏斗状树盘+秸秆覆盖处理的保水方式综合效果最好,对土壤含水率、全氮、速效养分、叶片可溶性糖、磷、钙含量以及果实产量均有显著提升作用,而漏斗状树盘+覆膜处理对产量的提升最明显,漏斗状树盘+覆膜或覆秸秆可以作为山区核桃园有效的保水措施。
In order to find out effective water-saving measures for high quality and efficient production of walnut in mountainous areas.‘Qingxiang’walnut was used as the experiment material to study the influence of different watercollecting measures on nutrition of soil and leaf,yield and quality of fruit in walnut orchard of mountainous areas.The results showed that different types of water-collecting measures all had obvious water retention effects in 0-20 cm and 20-40 cm soil layers.The water collecting treatment in which the funnel-shaped tree tray was covered by straw had the best comprehensive effect,and the content of moisture,total nitrogen,available nutrients in soil,soluble sugar,phosphorus,calcium in leaf and fruit yield were significantly improved,while the funnel-shaped tree tray plus film mulching treatment had the most obvious increase in yield.As a conclusion,funnel-shaped tree tray covered with film or straw can be used as an effective water-collecting measure for walnut orchard in mountainous areas.
