行间生草对灵武长枣种植园小气候的影响

Effects of inter-row green covering on microclimate in Lingwu Long Jujube garden

为给灵武长枣高效、优质栽培的培肥技术提供理论依据,在宁夏灵武长枣种植区分别设置了自然生草、紫花苜蓿、百脉根、黑麦草、白三叶草共5个行间生草处理,以清耕为对照处理,就不同生草处理对灵武长枣种植园小气候环境的影响情况进行了试验研究与观测分析。结果表明,与清耕(对照)处理相比,不同生草处理对种植园小气候环境的影响效果均明显;在夏季,各生草处理均可降低空气温度和地表光照强度,其中,白三叶草处理能提高空气相对湿度与空气CO_2浓度。

In order to provide some theorical basises for high-effective and high-quality cultivation techniques of Lingwu Long Jujube,five inter-row green covering treatments of natural growing-grass,Medicago sativa,Lotus corniculatus,Lolium perenne and Trifolium repens were set at the planting region of Lingwu Long Jujube in Ningxia,taking cleaning tillage as CK,this paper studied and analyzed effects of inter-row green covering on microclimate environment at Lingwu Long Jujube garden.The results show that effects of different treatments on the microclimating environment of planting garden were obvious.Air temperature and surface light intensity were decreased in summer,but relative air humidity and atmospheric CO_2 concentration were increased in the treatment of T.repens.
