间作对油桐树体生长影响研究

Effects of Different Agroforestry Patterns on Growth and Nutrient of Branch and leaf of Vernicia fordii

选择油桐+红薯、油桐+黄豆和油桐+玉米不同套种模式,研究了不同桐粮套种模式,对油桐幼林树高、地径、分枝数、分枝长度和分枝粗度等生长性状的影响。结果表明:不同套种模式间对油桐幼林的树高、地径、分枝数、分枝长度和分枝粗度等生长性状影响存在显著差异,油桐+玉米套种模式更能促进油桐幼林生长,尤其是对油桐的树高及分枝长度两个生长性状影响更大。

We selected differeat intercropping patterns of V .fordii and Ipomoea batatas ,V .fordii and Glycine max , V .fordii and Zea mays ,and we investigated effects of agroforestry patterns on height,diameter,branches,branch length and branch thickness of V .fordii young stand.Additionally,the agroforestry patterns which could promote faster growth were studied by means of variance analysis and multiple methods.Results showed it had significant difference in effects of height,diameter,branches,branch length and branch thickness on different intercopping patterns.The agroforestry pat-tern of V .fordii and Z .mays could promote faster growth,especially for height and branch length.
