一、引言“返生根”是造林前从漆苗上剪下的根,它是漆树育苗的重要种根来源。由于漆树秋冬栽植造林,幼林抗旱性强,成活率高,生长快,因此,“返生根”一般是在秋末冬初起苗时被剪下。此时离体后的“返生根”能否越冬,用什么方法贮藏,是决定秋冬栽漆成活与否的关键。为了解决这个问题,我们曾于1965年10月至1966年10月在平利县农林局苗圃进行了“返生根”冬藏试验,现将所得结果报告如下:二、基本情况平利县苗圃设在平利县城东约3公里的地方。苗圃地位于海拔550米的川道地,地势平坦,地下水位较高,土壤湿润、酸性砂壤。圃地前茬植物为漆树。当地属亚热带气候,气候温和,雨量充沛。据平利县气象服务站资料,1965年当
I. Introduction “Regeneration root” is the root cut from the lacquer before afforestation, which is an important root of seedling lacquer. As the autumn and winter planting of plantation afforestation, young forest drought resistance, high survival rate, rapid growth, therefore, “back root” is generally cut off in the late autumn and winter early seedling. At this point in vitro after the “return root” can wintering, what method of storage, autumn and winter paint is to determine the survival or not. In order to solve this problem, we conducted a winter-Tibet test of “returning roots” from October 1965 to October 1966 in the nursery of Pingli County Agriculture and Forestry Bureau. The results are reported as follows: II. Basic Information In Pingli County, about 3 km east of the place. Nursery at 550 meters above sea level in Sichuan Road, flat, high groundwater level, the soil moist, acidic sandy soil. Nursery plants for the former tree. The subtropical climate, the climate is mild, abundant rainfall. According to Pingli County weather service station data, when 1965
