| 摘 要： | 本研究采用微藻粉末和植物性吸水材料包衣处理两种牧草种子，并接种微生物孢子，观察植株生长和土壤微生物的呼吸量。结果表明，种子包衣并接种孢子时，两种牧草的干物质量（P<0.01）、豆科牧草的根瘤数（P<0.05）和土壤微生物呼吸量（P<0.05）均显著高于对照；植株的干物质量与土壤呼吸量之间呈极显著的正相关（P<0.001）；豆科牧草根瘤数与土壤呼吸量之间也呈极显著的正相关(P<0.001）。植株收获后，在各种处理的土壤上再播种未经过包衣和孢子处理的种子，其植株的干物质量、根瘤数和土壤微生物呼吸量均与第1茬植株有同样的变化趋势。种子包衣和接种微生物，为土壤微生物提供生长所需的条件，提高了土壤微生物的活性，促进了植物生长，土壤微生物活性的提高效应是可延续的。

| Abstract: | Seeds of two forage species were coated with mixtures of algal powder and plant-derived hygroscopic polysaccharide gums.The coated seeds were inoculated with spores of microorganism.Objectives of the study were to examine effects of seed coating and inoculation of spores on plant growth and sustainable effect of seed coating on plant growth and soil conditions.The results showed that dry weight(P<0.01),nodule number(P<0.05) and CO2 emission of soil(P<0.05) of the coated seed plants were higher than those of... |
