摘要
为了系统地研究野漆树轻型基质播种育苗技术,以江西宁都团结水库采集的野漆树种子为材料,进行了轻型基质播种育苗中的水分控制试验。水分控制试验设置1天、3天和5天共3个不同的浇水间隔处理,分别在第15天、第30天2次测量生长指标,研究浇水间隔对野漆树轻型基质苗的苗高、地径和复叶长度的影响。结果表明:不同浇水间隔处理的对比中,野漆树轻型基质苗的苗高、地径和复叶长度均表现出显著的差异。苗期苗木的高度生长在水分控制条件下,初期水分控制的方式影响到苗木在后期的苗高的生长速率;见干见湿的控水处理对地径的生长有利,但过度控水则地径生长不明显;育苗前期,复叶长度在控水的情况下生长迅速,1天1次的浇水处理对其生长不利;育苗后期,充足的水分有利于新陈代谢的进行,更利于叶片的生长。前期控水、后期水分充足的措施对叶片生长有利,并且适度控水比过度控水更有利于叶片的生长。因此,以间隔3天的浇水处理对于苗木高度、地径、复叶长度的生长最有利,为人们在苗期的水分管理和后期的造林均提供了指导性的理论依据。
To systematically study the techniques of light medium seedlings of Toxicodendron succedaneum, taking the seed of Toxicodendron succedaneum in Jiangxi for the materials, seedlings were planted in the light matrix of water control test. Water control test set a total of 3 different treatment intervals of watering of 1 day, 3 days and 5 days, respectively measurements growth indicators twice in the 15th day and 30th days to study about intervals of watering light matrix system of Toxicodendron succedaneum seeds breeding on seedlings height, diameter and length of compound leaves. The results showed that： the comparison of different treatment intervals in the water, the Toxicodendron succedaneum seed breeding on seedlings height, diameter and length of compound leaves had shown significant differences. Seedling height growth of seedlings under conditions of controlled in the water, the initial impact of water in a controlled manner would be affected to the seedlings in the latter part of the growth rate of height; wet and dry harmony was beneficial for the control growth path to ground water, but excessive control of the water in diameter growth was not obvious; nursery early, compound leaf length in the case of water control rapid growth, once a day of the watering treatment for the negative growth; nursery late, plenty of moisture was conducive to metabolism and more conducive to the growth of leaves. Early control of water, measures of moisture adequate later for the leaf growth was beneficial and appropriate control the water more conducive than the over-control water was to the growth of leaves. Therefore, an interval of 3 days of water treatment for seedling height, diameter, and length of growingcompound leaf was the most favorable, which provided a guided theory for people in watering at the seedling stage and late planting.
