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 sweet grass orchard was chosen as the research object to study the effect of natural pasture on the temperature and humidity of 0 ~ 30cm soil layer and 50 ~ 200cm canopy in sweet cherry orchard from the perspective of location monitoring. Park management provides a reference. The results showed that compared with tillage, natural grassland reduced daily maximum temperature and diurnal temperature difference between 0 and 30 cm and increased soil water content, but it was not conducive to drainage in rainy seasons, leading to waterlogging stress of local root system. The highest temperature of the canopy.
