袋包型施肥方式对4个树种苗期耐肥性的影响

Effect of Fertilizer Tolerance of Bag Type Fertilizer on Seedling Stage of 4 Tree Species

为了解树种苗期的耐肥性,选择油茶、马尾松、杉木、香樟苗木为试材,采用不同施肥方式(专利袋包型缓释肥、无纺布袋包肥、普通施肥),并以不施肥为对照,进行盆栽施肥试验。结果表明:每盆施复合肥(其N、P_2O_5、K_2O的质量百分比为16∶6∶8)60.0 g·盆^(-1)的条件下,4个树种苗期耐肥大小为马尾松>杉木>香樟>油茶,即油茶最不耐肥,因此油茶苗期施肥一定要小心,不能过量。同时,袋包型缓释肥在盆栽试验中可大大降低苗木死亡率,对大田育苗施肥具有参考价值。

In order to understand the fertilizer resistance of tree species at seedling stage ,4 tree species, such as Camellia oleifera, Pinus massoniana, Cunninghamia lanceolata and Cinnamomum camphora were selected to carry out experiments at Seedling Stage. Test set of 4 different fertilization modes, including the patent bag controlled-release fertilizer, non-woven bag and ordinary fertilizer, fertilizer fertilization of 4 different fertilization methods on 4 tree seedlings in the pot buried bag release test were determined through the analysis of the test results. The seedling survival table. The results showed that in each pot of tea saponin containing compound fertilizer fertilizer （N, P2O5, K2O quality percentage is 16： 6：8 ） under the condition of 60. 0 g, the seedling size of 4 tree species was Masson Pine 〉 Chinese fir 〉 camphor 〉 Camellia oleifera, Camellia is most resistant Camellia seedling fertilizer, so we must be careful, not too much. And the Chinese fir as fast-growing tree species, seedling fertilizer research is very important. At the same time, the bag type slow release fertilizer has a good slow-release effect, and it can greatly reduce the mortality of the seedlings in the pot experiment, which is important for the fertilizer in field nursery.
