为了培育良种,改善水杉、池杉的遗传品质,促进速生、丰产、优质。我们遵照伟大领袖毛主席“有了优良品种,即不增加劳动力、肥料,也可获得较多的收成”的教导,从1973年以来,开展水杉、池杉种子园营建工作。几年来,我们共收集水杉优树48株,池杉优树66株,落羽杉优树15株,墨西哥落羽杉母树2株。嫁接成活各类苗木17486株,其中:水杉12711株,池杉4330株,落羽杉403株,已定植种子园300亩(水杉210亩,池杉80亩,落羽杉10亩)。1974年定植的水杉种子园,1975年育两株开始开雌花,1976年又有6株共结球果近100个,今春又嫁接水杉、池杉、落羽杉苗23900多株,预计明春可完成450亩的建园任务。
In order to cultivate seed, improve Metasequoia, Iii fir genetic quality, promote fast-growing, high yield, high quality. We have followed the teachings of Chairman Mao, the great leader, “with excellent varieties, that is, we can get more crops without increasing labor force and fertilizers.” Since 1973, we have started the construction of the Metasequoia firmachii seed orchard. In recent years, we have collected a total of 48 superior trees of Metasequoia, 66 of Ipomoea fasciatus, 15 of Tricholoma matsutake, 2 of Mexico’s Tricholoma matsutake. Grafting survival of all kinds of nursery stock 17486 strains, of which: 12,711 metasequoia, 4330 Ipomoea, 403 dead Taxanes, 300 acres have been planted seed orchard (210 acres of Metasequoia, 80 acres of Ipomoea Taxus 10 acres). 1974 planted Metasequoia seed orchard, in 1975 two plants began to open female flowers, in 1976 there are 6 strains of cones nearly 100 this spring and is also the graft Metasequoia, Ipomoea japonica, Taxodium lanceolata more than 23,900 plants, is expected to spring 450 acres of completed park mission.
