药用矮化银杏引种栽培试验初报

Primary research on intruduction and cultivation of the medicinal dwarf ginkgo

试验研究了不同栽培品种、不同栽培密度、不同覆盖方式对药用矮化银杏(Ginkgo biloba L.)成活率、生长势及田间控草效果的影响,同时还通过间作种植(玉米、毛豆)研究了药用矮化银杏苗圃提高育苗成活率、壮苗率的方式。结果表明,药用矮化银杏建园时,避免强光直射地域,选择大佛手、恩施银杏等品种,可有效缩短移栽缓苗期、提高成活率;药用矮化银杏园利用黑塑料膜覆盖可有效防止杂草,节约成本;在药用矮化银杏苗圃间作玉米,可提高银杏育苗成活率、壮苗率,增加收入。

This research compared the effect on the survival rate, growth potential and weeds control of medicinal dwarf ginkgo(Ginkgo biloba L.) with different cultivars, different cultivation densities and different mulching methods, and investigated the methods of improving the seedling survival rate and seedling strengthening rate by intercropping corn and soybean in the medicinal dwarf ginkgo. The results showed that, the cultivars Great Buddha hand and Enshi Ginkgo were recommended to build the medicinal dwarf ginkgo nursery with avoiding the area of direct light and direct light, which can effectively shorten the period of transplanting and improve the survival rate of medicinal dwarf ginkgo. Covering black film ground can effectively prevent weeds and save costs. Also, intercroping corn in the medicinal dwarf ginkgo could improve the seedling survival rate of medicinal dwarf ginkgo nursery and obviously increase the economic efficiency.
