间作对油茶幼林生长及土壤养分的影响

Effects of Intercropping on the Growth and Soil Nutrients of Young Camellia oleifera Forest

  • 摘要: 采用野外调查与室内分析测定的方法,研究了间作对油茶幼林、油茶林地土壤养分及林地经济效益的影响。结果表明:间作提高了油茶造林成活率和林地经济效益,不同间作对油茶林地土壤养分的影响不同;根据油茶幼树植株及间作物对养分元素的需求,间作大豆应适当追施钾肥和磷肥,间作茄子应适当追施氮肥和钾肥。油茶新造林间作具有一定的可行性,但因地制宜和合理间作是取得理想效果的必要前提。

     

    Abstract: Based on the field investigation and soil analysis,studies were made of effects of intercropping on the growth,soil nutrients and benefit of young Camellia oleifera forest. The main research results were as follows:by intercropping with soybean,eggplant and chili in young C.oleifera forest,the survival rate of afforestation and benefit of young C.oleifera forest increased,but the effects of different intercropping on soil nutrient were different. According to nutrient requirement of C.oleifera sapling plants and crops,intercropping soybean should be appropriate to employ potash and phosphate fertilizers,intercropping eggplant should be appropriate to employ nitrogen and potash fertilizers. Intercropping in C.oleifera afforestation was feasible,but according to local conditions,reasonable intercropping was a necessary prerequisite to achieve the desired effect.
