容器育苗工厂化生产技术,是一项综合性很强的试验研究工作,本项目对工厂化育苗的环境工程、机械设备、工艺流程、育苗技术、病虫害防治技术以及容器苗造林技术进行了系统研究,为提高其研究水平,实用价值,并开展了菌根、稀土元素、吸水剂等新技术在容器育苗中的应用研究,以及小气候与苗木生长关系的观察分析。试验研究结果表明:工厂化容器育苗,具有苗木生长快、质量好、适应性强等优点,可缩短成苗期1—2倍,提高造林成活率30~50%;菌根、稀土元素、施肥等应用试验效果明显,可显著促进苗木生长,对提高西北干旱半干旱地区营林水平具有重要作用。
Container nursery factory production technology, is a comprehensive research and experimental work, the project of plant nursery environmental engineering, mechanical equipment, process flow, nursery techniques, pest control techniques and container seedling afforestation technology were systematically studied In order to improve the research level and practical value, the application of new technologies such as mycorrhiza, rare earth elements and water-absorbing agent in the container seedling raising and the observation and analysis of the relationship between microclimate and seedling growth were carried out. The experimental results show that the factory container seedling has the advantages of rapid growth of seedlings, good quality and strong adaptability, which can shorten the seedling stage by 1-2 times and improve the survival rate by 30-50%. Mycorrhizal, rare earth elements, fertilization Application of test results such as obvious, can significantly promote the growth of seedlings, to improve the level of the arid and semiarid areas of Northwest China forest plays an important role.
