为使插叶成活,首先必须保存银杏叶的生活力,并创造成活生长发育的优良环境条件。夏季光照强度大,温度高,蒸腾量大,病原菌繁殖快,此时,银杏叶插后易干枯或腐烂。因此,宜选择地势平坦、土层深厚、土质为沙壤土、pH值6.5—7,靠近水源,侧方有遮荫树木的地段。修建半地下式拱棚,并以苇帘遮荫。拱棚内铺细河沙20厘米厚,作为苗床。设置喷水设施,扦插前苗床需消毒。 6月上旬至8月中旬,采集银杏叶片,用自制催根剂处理后,扦插入床深1.5—2厘米,每平方米1000片
To make the leaves survive, we must first save the vitality of Ginkgo biloba and create an excellent environment for growth and development. Summer light intensity, high temperature, large transpiration, rapid propagation of pathogens, this time, Ginkgo biloba easy to dry or decay. Therefore, should choose flat topography, deep soil, sandy loam soil, pH 6.5-7, close to the water, side shade trees. Built semi-underground arch, and reed curtain shade. The arch shed thin sand 20 cm thick, as a seedbed. Set water facilities, cutting seedbed before disinfection. From early June to mid-August, Ginkgo biloba leaves were collected and treated with a self-made catalyst. The cuttings were inserted into a bed 1.5-2 cm deep and 1000 pieces per square meter
