黑松等轻基质无纺布容器育苗技术的研究与应用

Studies on the Seeding Technology of Light Medium Non-woven Container of Pinus thunbergii Parl.

以鲁南地区主要造林树种黑松、侧柏和刺槐为试材,开展了轻基质无纺布育苗技术研究,筛选出了针叶树种轻基质无纺布育苗基质配比是:草炭土:珍珠岩:蛭石=60:20:20;阔叶树种轻基质无纺布育苗基质配比是:草炭土:珍珠岩:蛭石=70:15:15。通过开展基质缓释肥用量试验,表明基质中基肥的用量应按树种、培育周期、容器大小及基质肥沃程度等确定。对于针叶树种来说,对肥料的需求相对较小,1%的添加量即可满足一个生长周期(1a)的需要;而对于阔叶树种来说,对于肥料的需求量较大,1.25%可满足一个生长周期(1a)的需求。

In this study,Pinus thunbergii Parl.,Platycladus orientalis and Robinia pseudoacacia L.were used as the test materials to carry out the study of the seedling technology with light medium non-woven container,and selected the medium ratio of coniferous trees was:peat soil:perlite:vermiculite=60:20:20;selected the medium ratio of coniferous trees was:peat soil:perlite:vermiculite=70:15:15.By conducted a test of slow-release fertilizer dosage,the results showed that the needs of fertilizer in the medium according to the tree species,cultivating cycle,container size and the fertility of medium.For coniferous trees,the demand for fertilizer is little,and 1%added amount can satisfy the needs in a growth cycle(1a);for broad-leaved trees,the demand for fertilizer is more,and 1.25%added amount can satisfy the needs in a growth cycle(1a).
