池杉在我省平原湖区,已广泛栽培。为了满足对池杉造林用苗的需要,我省有关单位对池杉育苗技术,进行了广泛的科研和生产实践。已取得了较成功的技术经验,苗木质量正在不断提高。随着人们对良种壮苗认识的逐渐加深,要求的日益迫切,对如何确定池杉壮苗形态指标,促进育苗技术的进一步提高已成为当前急待解决的问题。为此,我们于1978年底在我省五县一市池杉育苗水平较高的8个场所进行了一年生实生苗苗木质量的调查,拟定了池杉实生苗形态指标。现将调查研究的结果整理分析于下。一九七八年我们对云梦、洪湖、沔阳林
Ipomoea in our province plain lake area, has been widely cultivated. In order to meet the need for afforestation with Ipomoea cirsium, relevant units in our province carried out a wide range of scientific research and production practices. Has achieved more successful technical experience, seedling quality is constantly improving. With the gradual deepening of people’s understanding of strong seedlings, the demand is increasingly urgent, how to determine the shape of seedlings fir seedling indicators, to promote further raising seedling technology has become the current urgent problems. To this end, we in the end of 1978 in five counties in our province a higher level of seedlings of Ipomoea cesarean section 8 were investigated the quality of annual seedling seedlings, drafted landed fir seedling morphological indicators. Now the results of the investigation and analysis of the next analysis. In 1978 we Yunmeng, Honghu, Ying Yang Lin
