红锥容器育苗的试验研究

Nursery Trials on Container Seedling of Castanopsis hystrix

通过开展以不同育苗基质与移苗阶段作组合和以不同断根方式与根部处理作组合的红锥容器苗育苗试验,对影响红锥容器育苗效果的因素组合进行了研究。研究结果表明:不同的处理方式对红锥容器苗的成活及生长指标存在显著的影响。其中不同育苗基质和不同断根方式是其主要的影响因素。以红泥营养杯下垫火烧土的处理对红锥容器育苗的苗木保存率和苗木高生长的影响效果最好,而以单纯红泥作为育苗基质的处理对其苗木地径生长的影响最大。以在芽苗出土前进行切根处理对于红锥容器苗的苗木保存率、苗高及地径生长影响的效果最佳。但在芽苗出土前进行切根处理则对于其苗木根系的生长更有好处。

Nursery trials on container seedling of Castanopsis hystrix including seedling raising medium, transplanting time, root pruning and root treatment, were conducted. The results implied that the survival and growth of seedlings were significantly affected by different treatments, among all the experimental treatments, medium and root pruning were major factors in seedling raising of C. hystrix. Red mud nutrient cup with heated soil at bottom was promising for seedling keep rate and height growth, red mud was good medium for diameter growth. Pruning root before come up could increase seedling keep rate, promote growth of both height and diameter. The root system development could be improved by pruning root before come up.
