以清耕为对照(CK)，套种紫云英、毛叶苕子、箭筈豌豆、黑麦草 4 种绿肥，于绿肥返青期至盛花期定期检测土壤温度和湿度，盛花期调查杂草种类密度，研究绿肥对猕猴桃园土壤温度、土壤湿度及杂草种类、数量等群落特征的影响。结果表明:与CK相比，套种绿肥对猕猴桃园土壤温度调节作用明显，土壤温度变化幅度均低于CK，其中毛叶苕子变化幅度最小。从 3 月中旬至 5 月上旬，与对照相比，种植紫云英、毛叶苕子、箭筈豌豆、黑麦草的土壤平均含水量分别提高了 104。8%、97。8%、147。3%和 82。3%。5 月 5 日，种植毛叶苕子和箭筈豌豆的土壤平均含水量分别为 29。8%和 30。1%，显著高于对照和其他处理。与对CK相比，猕猴桃园套种绿肥后杂草数量和种类均不同程度的减少。绿肥种植对早熟禾、看麦娘、鹅肠草、罔草、野老鹤草和车轴草抑制效果最为明显，密度分别平均减少了 100%、86。35%、85。08%、75。73%、69。69%和 89。6%。以套种毛叶苕子的果园杂草总密度最低(12。97 株/m2)。综上，相对于清耕(CK)处理，毛叶苕子对猕猴桃园的环境适应性优于其他绿肥品种，在稳定土壤温度、提高土壤含水量、降低农田杂草的密度和种类、改变杂草群落组成结构，以及调节果园小气候等方面的综合效果最佳。
Effect of Green Manure Intercropping on Soil Temperature,Humidity,and Weeds in Kiwifruit Orchards
With clear tillage as control(CK),four kinds of green manure,namely Astragalus sinicus L.(AS),Vicia villosa Roth(VR),Vicia sativa L.(VS),and Lolium perenne L.(LP)were intercropped.Soil temperature and humidity were detected regularly from the period of seedling establishment to the full-blossom period,and weed species density was investigated at the full-blossom period.The effects of green manure on soil temperature,soil humidity,weed species and quantity,and other community characteristics in kiwifruit orchards were studied.The results show that compared with CK,intercropping green manure has an obvious effect on soil temperature regulation in kiwifruit orchards,and the variation range of soil temperature is lower than CK.The variation range of VR is the least.From mid-March to early May,compared with the CK,the average water content of the soil with AS,VR,VS,and LP planted increases by 104.8%,97.8%,147.3%,and 82.3%,respectively.On May 5,the average water content of the soil with VR and VS planted is 29.8%and 30.1%,respectively,which is significantly higher than CK and other treatments.Compared with the CK,after intercropping green manure in kiwifruit orchards,the number and species of weeds decrease to different degrees.The green manure has the most obvious inhibition effect on Poa annua L.,Alopecurus aequalis Sobol.,Myosoton aquaticum(L.)Moench,Beckmannia syzigachne(Steud.)Fern.,Geranium carolinianum L.,and Trifolium pratense L..Their densities are decreased by 100%,86.35%,85.08%,75.73%,69.69%,and 89.6%,respectively.The total density of weeds in orchards intercropped with VR is the lowest(12.97 plants/m2).In conclusion,compared with CK treatment,the adaptability of VR to the environment in kiwifruit orchards is better than that of other green manure varieties.The comprehensive effect is the best in stabilizing soil temperature,increasing soil water content,reducing the density and species of weeds,changing the composition and structure of the weed community,and regulating the microclimate of orchards.
