摘要
以自然生草的甜樱桃园为研究对象,采用定位监测方法,研究了自然生草对甜樱桃园0~30cm土壤和距地表50~200cm冠层温湿度的影响,以期为自然生草甜樱桃园的管理提供参考依据。结果表明:与清耕相比,自然生草降低了0~30cm土壤日最高温度和昼夜温差,增大了土壤含水量,但在多雨季节不利于排水,易引起局部根系渍水胁迫;降低了冠层的最高温度。
Natural grass of sweet cherry orchard was used as research object,the effects of natural grass on the soil and canopy temperature and humidity of 0-30 cm soil and the surface of 50-200 cm canopy in sweet cherry orchard were studied by using the method of location monitoring,in order to supply refereace for management of natural grass of sweet cherry orchard.The results showed that natural grass reduced the maximum daily temperature and the temperature difference between day and night in 0-30 cm soil layer,increased the soil moisture content,but was not conducived to drainage during rainy season,which caused partial root water logging stress;and also reduced the maximum temperature of canopy.
