摘要
为筛选最适宜幼龄胶园覆盖材料,通过3 cm、2 cm、1 cm生物材料覆盖和地膜覆盖、秸秆覆盖,以裸地为对照,研究不同覆盖材料对土壤养分及温度的影响。结果表明,生物材料3 cm、1 cm处理硝态氮含量显著高于其他4个处理;薄膜覆盖处理速效磷和全磷含量显著高于其他5个处理;秸秆覆盖处理速效钾含量显著高于其他5个处理;铵态氮、全氮和全钾含量6个处理间没有显著差异。薄膜覆盖和裸地的土壤温度没有显著差异,生物材料3 cm、2 cm、1 cm和秸秆覆盖的土壤温度显著低于裸地。
In order to screen optimum cover material in immature rubber plantation, different mulching material treatments of pot experiment were carried out, which included 3 cm biological material, 2 cm biological material, 1 cm biological material, plastic film mulch, straw mulch. A flat plot without mulch was used as a control. The results showed that the nitrate nitrogen contents on 3 cm biological material mulch and 1 cm biological material mulch were significantly higher than that of four others, the contents of rapid available phosphorus and total phosphorus on plastic film mulch were significantly higher than those of five others, rapid available potassium content on straw mulch was significantly higher than those of five others, the contents of ammonium nitrogen, total nitrogen and total potassium were not significantly different on 3 cm biological material, 2 cm biological material, 1 cm biological material, plastic film mulch, straw mulch. In plastic film mulch and bare land ground, temperature was not significantly different, in 3 cm biological material, 2 cm biological material, 1 cm biological material, straw mulch, temperature was significantly lower than that in bare land.
