银杏嫩枝扦插技术简便易行,可以加快银杏繁殖速度,且可保证母本性状不变。1994—1995年,我们扦插银杏1.2万株,成活率在90%以上。一、生根环境的创造。搭遮荫棚。在通风有水源处建荫棚,棚高2米,材料可用木桩或石灰桩,棚顶及四周用双层苇帘遮挡,透光率在15—20%。扦插基质应选择重壤质潮土。土壤含水量在15—20%。要耕翻土壤,清除杂质做床,床面低于地表15—20厘米,床长6—7米,宽1—1.3米,畦周围挖宽、深各20厘米的排水沟。用高锰酸钾为土壤消毒,每平方米用量为5克。二、插穗选择与处理。从幼树上采当年生半木质
Ginkgo softwood cutting technology is simple and easy, can speed up the ginkgo breeding speed, and can ensure that the female parent trait unchanged. 1994-1995, we cut 12,000 ginkgo trees, the survival rate of 90% or more. First, the rooting environment to create. Take a shady shed. Ventilation in the shade at the water shed, studio shed 2 meters high, the material available pile or lime pile, roof and surrounded by double reed curtain, light transmittance of 15-20%. Cutting medium should choose heavy loamy soil. Soil moisture content of 15-20%. To plow the soil, remove impurities to bed, the bed below the surface of 15-20 cm, 6-7 meters long, 1-1.3 meters wide, digging around the width of 20 cm deep drainage. Potassium permanganate for soil disinfection, the amount of 5 grams per square meter. Second, cuttings selection and handling. The young trees were picked from young trees
