摘　　要：为探明不同棉花育苗床土调制剂的壮苗效果及机理,以湘棉10号为供试材料,比较研究了10种床土调制剂对棉花营养块育苗的生理影响.结果表明,以合适的药肥比混配的床土调制剂作基肥能显著提高苗期棉株根系活力,增加叶绿素含量,提高过氧化物酶活性,调节游离氨基酸含量和碳、氮营养比例,维持植株稳健生长.10 kinds of bed conditioners are used to compare their physiological effects on Gossypinm hirsutum L. seeding under condition of nutrient clump. The results are as follows:the optimum formula as basic fertilizer can enhance the rootvigour of cotton seedings, increase the content of chlorophyll, and promote the activity of peroxidase. Meanwhile, it could help bring about the sugarnitrogen ratio and free amino acids to maintain at adequate level in functional leaves, by regulating the intensity of nitrogen and carbohydrate metabolism of cotton with plant steadily grown.
