据综合调查,以下一些新技术措施对提高干旱地区造林成活率具有较好的效果。 1.植物休眠素。日本香川大学生物系研究出一种被称为“ABA”的植物休眠素浸渍液。这种休眠素既能促进植物生长,也有抑制植物生长、发芽的休眠作用。例如用它来浸渍某些蔬、菜、谷物种子,可避免生长过程中因遇低温而抽苔的问题。用它来处理某些苗木种子,财能增强其对环境的适应能力,实现在一些干旱地区的恶劣条件下栽种,或在过度干旱以后再发芽和成活。
According to a comprehensive survey, the following new technologies and measures have a good effect on improving the survival rate of afforestation in arid areas. Plant dormancy Japan Kagawa University Department of Biology has developed a known as “ABA” plant dormancy impregnation solution. This dormancy both promote plant growth, but also inhibit plant growth, germination and dormancy. For example, it is used to impregnate certain vegetables, vegetables and grains, which can avoid the problem of low temperature and bolting during growth. It is used to treat certain seedlings of seedlings, which enhance their ability to adapt to the environment, planted them in harsh conditions in some arid areas or germinate and survive after an over-drought.
