摘 要 ：为了探明免耕直播对杂交水稻的生育规律和稻田土壤理化性状的影响，于2003—2004年在长沙以两优培九为材料，进行了免耕直播、翻耕直播2种栽培方式的田间比较试验研究。结果表明，与翻耕直播稻田相比，免耕直播稻田0~5 cm土层容重降低3.55%，总孔隙度、毛管孔隙度、通气孔隙度和毛管持水量分别增加4.80%、1.59%、39.85%和7.04

Abstract:To explore the effects of no tillage and direct broadcasting (NTDB) on the growth pattern of hybrid rice and soil physical and chemical properties, a comparison experiment with rice cultivar Liangyoupeijiu was conducted under the conditions of NTDB and conventional tillage and direct broadcasting(CT
