  • 在京津风沙源区不同立地条件的沙区,采用砧木培养、接穗选择、嵌芽接技术使用、早晚温棚保温保湿等技术,组装完成文冠果嫁接苗1年出圃的高效繁育技术,使良种苗繁育效率显著提高(时间上由常规嫁接苗2年出圃缩短到1年出圃;成本是常规嫁接苗的1/2、组培苗的1/10左右),可以为比较寒冷的北方沙区大批量提供优良的生态经济型文冠果良种资源。该技术适用于京津风沙源区半干旱沙区的文冠果栽培。

    表    Please select and fill in the relevant technical information according to the following technical classifications for specific technologies.

    Technical link Key technical points Implementation season / month
    1. Selection of Suitable Grass Specie It is critical to identify grass species that will thrive in drought conditions. These species need to be drought-resistant, fast-growing, and capable of surviving with minimal water.
    2. Cultivation and Management The selected grasses are cultivated in nurseries before being transplanted to designated areas. Proper management practices, including regular watering (optimally through efficient methods like drip irrigation) and soil fertility management, are essential for their growth.
    3. Mushroom Cultivation Once the grasses are established, they can be harvested and used as a substrate for mushroom cultivation. This provides a sustainable source of food and income, as mushrooms can be sold in local markets.
    4. Soil Erosion Control Juncao grasses have dense root systems that help bind the soil, reducing erosion caused by wind and water.
    5. Animal Fodder The grasses can also serve as fodder for livestock, providing an additional resource for local communities and helping to reduce pressure on natural vegetation.
