摘要
Abstract
Flue-cured tobacco variety Yuyan No .10 was used as experimental material , and the effects of different fertiliza-tion modes on the physicochemical properties and microbial quantity of tobacco -planting soil in central Henan were studied .The results indicated that:in most period of tobacco growth period , the soil moisture content of good -quality tobacco leaf production technology fertilization mode (GQFM) and good-quality high-efficient production technology fertilization mode (GQHEFM) was higher than that of conventional production technology fertilization mode (CFM) and high-yielding production technology fertiliza-tion mode (HYFM), while the soil bulk density of GQFM and GQHEFM was lower than that of the latter two fertilization modes . The contents of available nitrogen , available phosphorus , available potassium and organic matter in soil of all treatments generally showed the changing trend of rising at first and then reduction , and reached a peak during 30~50 days after transplanting .The soil pH-value in tobacco growth period had no obvious change .The contents of available nitrogen , available phosphorus , available po-tassium and organic matter in soil of GQFM and GQHEFM were higher .The quantity of bacteria , fungi and actinomycetes in soil of various treatments all revealed a single -peak change along with the increase in day number after transplanting , and reached the highest value on about the 60th day after transplanting .The soil microbial quantity of GQFM and GQHEFM was generally higher than that of other fertilization modes .关键词
