水杉是一种落叶乔木,它具有生长快、病虫害少、树干粗大通直等优点,是水网地区四旁绿化较好的树种之一。当前水杉繁殖主要是硬枝或嫩枝扦插育苗,这种育苗方法化费劳力大,用的荫棚材料多、成本较高,而且在管理上稍有疏忽,成活率就比较低。我们遵照伟大领袖毛主席“要认真总结经验”的教导,经过工人同志们的反复试验,初步摸索出水杉埋株育苗方法,现将情况介绍如下:一、苗圃的选择和整地.苗圃地应选在排水良好、灌溉方便、地势平坦的地方。土壤要深厚、疏松、肥沃。在头年的秋末整地,深翻25厘米以上,做到土壤细碎、无草根、树根、石块。如用坡地育苗,应在坡地上方开有防洪沟。二、施肥作床.每亩可施腐熟过的土杂肥或麦肥1000斤,先将肥料均匀的撒开,然三、埋苗时间.以三月上、中旬为宜。
Metasequoia is a kind of deciduous tree, which has the advantages of rapid growth, less pests and diseases, thick trunk and straightness, and is one of the better tree species on the water network. The current propagation of Metasequoia is mainly hardwood or softwood cutting propagation, this method of breeding seedlings costly labor, the use of shade shed material, higher cost, but also slightly neglected in management, the survival rate is relatively low. Following the teachings of Chairman Mao, the great leader, “we must conscientiously sum up experiences,” we have tentatively explored the methods of planting seedlings of Metasequoia glyptostroboides through repeated experiments by workers’ comrades. The briefings are as follows: I. Selection and site preparation of nurseries. In a well-drained, irrigation convenient, flat terrain. The soil should be deep, loose and fertile. In the first year of the fall of the end of preparation, deep turning over 25 cm, so fine soil, no grass roots, roots, stones. Such as the use of slope nursery, flood control ditch should be opened above the slope. Second, fertilization for the bed. Per acre can be applied to the spoils of miscellaneous soil or wheat fertilizer 1000 kg, first evenly spread fertilizer, and then three, buried seedlings time to March, mid-appropriate.
