文冠果是起源于我国北方地区珍贵的木本油料树种,在它的天然分布区内,主要生长在山区、丘陵和排水良好的坡地上,这就形成了文冠果适应于干旱、寒冷条件下的种种特性。这些特性反映在不同的器官上也是很明显的。本文只对文冠果根颈部分的特性提出一些不成熟的看法,供讨论。 文冠果引入我区已有十多年的历史,积累了不少栽培经验,但苗期和移植后陆续死亡的情况比较普遍。这一问题目前全国文冠果天然分布区和引种区尚无一有效的解决办法。究其原因比较复杂,一般致死原因主要有:土壤病虫危害根系;土壤水分过多、板结、通气不 Wen Guan fruit is originated from the precious woody oilseeds species in northern China. In its natural distribution area, it mainly grows in mountainous, hillside and well-drained slopes, which makes it suitable for drought and cold conditions Under the various characteristics. It is also obvious that these characteristics are reflected in different organs. This article only presents some immature ideas about the characteristics of the neck portion of the root of the article, for discussion. Wen-huang fruit has been introduced into my area for more than ten years and accumulated a lot of cultivation experiences. However, it is common for seedlings and successive deaths after transplantation. At present, there is no effective solution to this problem in the natural distribution area and introduction area of ​​the Chinese crown. The reason for the more complex, the main causes of death are generally: soil pests harm root system; soil moisture, compaction, ventilation is not
