    十月蘋果樹的栽培管理技術,想要了解,一起來看看吧!

    1、采后葉面噴肥。采果后全樹噴3%~5%尿素1~2次,延緩葉片衰老,增強光合作用,增加貯藏養分,促進花芽分化,保證樹體安全越冬。

    2、秋施基肥。秋季是果樹根系的第3次生長高峰,根系生長量最大,吸收能力最強,傷根易愈合,且能促發新根增加吸收面積。近期土壤墑情好,溫度適中,有利于肥料轉化吸收和養分貯藏利用,9月沒有施基肥的果園,一定要抓緊時機,盡早秋施基肥。

    3、行間種草。趁墑行間播種油菜、黑麥草等。

    4、病蟲害防治。防治蘋果腐爛病,采果后樹體噴布晴菌唑或菌毒清1次,預防腐爛病從卸果后果柄脫離樹體的傷痕入侵。秋季是腐爛病的第2個高發期,在增強樹勢的同時,于基肥施后,及早對主干、主枝、枝杈等處刮除粗、老、翹皮,集中銷毀(發現腐爛病疤徹底刮治),并用氟硅唑、戊唑醇或甲基硫菌靈涂藥處理,腐爛病嚴重的果園,間隔15天,復涂1次;預防大青葉蟬為害。為避免大青葉蟬在幼樹枝條上產卵造成枯枝、死樹,可于10月上旬在幼樹主干、主枝上涂白,防止大青葉蟬產卵。
