不同土壤基质对五脉地椒栽培成活率及生物量的影响

Effects of Various Soil Substrate on Survival Rate and Biomass of Thymus quinquicostatus

以五脉地椒为材料,栽培在壤土、砂壤土(壤土与砂按1:2比例混合)及砾质土(原生境土)三种土壤基质中,研究不同基质对五脉地椒栽培成活率及生物量的影响。结果表明:以砾质土为生长基质的五脉地椒的栽培成活率、生物量鲜重及干重最高,以砂壤土为生长基质的五脉地椒的栽培成活率、生物量鲜重及干重次之,但与前者均无显著差异;而以壤土为生长基质五脉地椒的栽培成活率、生物量鲜重及干重最低,与前两者均差异显著(p<0.05)。由此得出五脉地椒的最适合生长基质为砾质土和可以代替的相似性土壤基质为砂壤土。同时研究发现栽培基质对五脉地椒地上生物量与地下生物量的分配影响不明显。

In this paper, we introduce a family of new smoothing functions. Based on a family of new smoothing functions, the nonlinear complementary problem is transformed into a nonlinear equations. The Newton algorithm is presented for solving the nonlinear complementarity problems. Under mild assumptions, we prove that the Newton algorithm is both globally and locally convergent.
