| 摘 要： | 近年来,国内外对秸秆覆盖的整体功能和节水效应1～4]已有较多研究,但对秸秆覆盖地的小气候效应研究较少。小气候效应能够反映秸秆覆盖的机理和功效,为秸秆覆盖的进一步研究提供科学依据。本文对不同水分条件下的秸秆覆盖处理进行了研究,目的是了解秸秆覆盖冬小麦田的小气候效应。1 设计与方法1.1 试验地点试验于1996～1997年在郑州市南郊河南省气象局科学研究所试验基地进行。试验地土壤为砂壤土,肥力中等。小麦供试品种为温麦4号。1.2 试验设计试验设置了麦秸覆盖、玉米秆覆盖、裸地(对照)三种形式,以及土壤含水量占田间持水量的40%～5… |

| Abstract: | The winter wheat field straw mulching was conducted. Compared with the unmulched field, the straw mulching could alter turbulent heat exchange, evaporative heat loss and soil heat fluxes, and improve the temperature and humidity of air close to the ground as well as play a active role in water-saving and soil moisture retention, thus provided better microclimatic conditions for the growth and development of winter wheat. |
