Abstract

Abstract:

【Objective】 The purpose of this study is to investigate the species composition and dominant species of the weed seed bank in the oasis irrigation area of Xinjiang.【Methods】 To analyze the correlation between the density of dominant species and soil physicochemical factors, as well as the influence of environmental factors on weed seed germination.【Results】 The results showed that a total of 19 species of weeds in 11 families were detected in the soil samples, including 14 species, 13 species and 17 species under mulched, diffuse and non-mulched drip irrigation, respectively.Based on the analysis of relative dominance and weed density: E.crus-galli, C.glaucum, A.retroflexus, S.viridis, A.theophrasti, and H.trionum.It is the dominant weed in corn field in weed seed bank.The correlation analysis between the density of dominant species and soil physicochemical factors showed that soil EC value was the main factor affecting the density of A.retroflexus, C.glaucum and E.crus-galli, organic matter was the main factor affecting the density of S.viridis, phosphorus content was the main factor affecting the A.theophrasti, and phosphorus content promoted the growth of H.trionum.There was a positive correlation between the germination rate and temperature of six kinds of weeds in corn field, E.crus-galli, C.glaucum, A.retroflexus, S.viridis, A.theophrasti, and H.trionum.【Conclusion】 The germination rate of six corn weeds, namely A.retroflexus, S.viridis, C.glaucum, H.trionum, A.theophrasti and E.crus-galli were positively correlated with temperature and water potential, but negatively correlated with salt stress.Under the condition of pH 8-10, six kinds of weeds could germinate normally.

摘要：

【目的】研究新疆绿洲灌区玉米田杂草种子库的物种组成及其优势种。【方法】分析优势种密度与土壤理化因子的相关性及环境因子对杂草种子萌发的影响。【结果】土壤样品中共检出玉米田杂草种子11科19种,覆膜滴灌、漫灌和不覆膜滴灌分别为14种、13种和17种,稗草Echinochloa crus-galli (L.) P.Beauv.、灰绿藜Chenopodium glaucum L.、反枝苋Amaranthus retroflexus L.、狗尾草Setaria viridis (L.) Beauv.、苘麻Abutilon theophrasti Medikus和野西瓜苗Hibiscus trionum L.为杂草种子库中玉米田优势杂草;土壤EC值是影响反枝苋密度、灰绿藜密度和稗草密度的主要因素,有机质是影响狗尾草密度的主要因素,磷是影响苘麻的主要因素,磷对野西瓜苗的生长有促进作用。【结论】反枝苋、狗尾草、灰绿藜、野西瓜苗、苘麻和稗草6种玉米田杂草种子的发芽率与温度和水势呈正相关,而与盐胁迫呈负相关。在 pH 8~10 条件下6种玉米田杂草种子均能正常萌发。
