枣园生草对土壤养分及果实品质的影响

【目的】研究不同生草对土壤养分及果实品质的影响,为宁夏灵武长枣栽培模式优化提供依据。【方法】于枣园行间种植不同的草种,进行方差分析。【结果】枣园生草提高枣园0~40 cm土层土壤有机质、全氮、全磷、碱解氮、速效磷、速效钾的含量枣园种粒黑麦草和白三叶可提高果实VC和类黄酮含量、降低有机酸含量、增强果实硬度;紫花苜蓿处理可明显提高单果重。【结论】枣园生草可提高种植园土壤肥力、改善果实品质,其中黑麦草和白三叶行间生草效果优于其他草种。

Effects of Grass Growing on Soil Nutrients and Fruit Quality in Jujube Orchard

【Objective】 In order to solve the shortcomings of the traditional cultivation mode of Lingwu Changzao, the effects of different grass-growing modes on soil nutrients and fruit quality were studied.【Method】 Variance analysis and charts were used to analyze the different grass-growing patterns in jujube orchards.【Result】 The contents of organic matter, total nitrogen, total phosphorus, alkali-hydrolyzable nitrogen, available phosphorus and available potassium in 0-40 cm soil layer of jujube orchard were increased by grass growing in jujube orchards; the content of VC and flavonoids in fruit was increased by ryegrass and white clover, the content of organic acid was decreased, and the firmness of fruit was enhanced by grass growing in jujube orchards; the single fruit weight was obviously increased by alfalfa treatment.【Conclusion】 The grass-growing model in jujube orchard can improve soil fertility and fruit quality, and the effect of ryegrass and white clover inter-row grass-growing model is better than other grass-growing models.
