经济林下鼠茅和白三叶培育抑制杂草及冬季绿化研究

Research on weed control and winter greening in economic forest undergrowth by cultivation of Trifolium repens and Vulpia myuros

  • 摘要:
    目的 为解决冬季落叶经济林杂草滋生及冬季缺绿问题。
    方法 于2021—2023年在庆元油茶林、松阳香榧林、莲都猕猴桃基地进行两种生草鼠茅(Vulpia myuros)和白三叶(Trifolium repens)的生草抑草实验,对比对照清耕组、白三叶组和鼠茅组的抑草效果。同时,比较猕猴桃基地种植白三叶和鼠茅的冬季绿化效果,通过对比草坪密度、耐寒性、抗病性、抗旱性、绿色期、颜色、抗草能力、管抚难度8个指标来评价两者的冬季护绿效果。
    结果 白三叶组第1年抑草效果达58%~94%,第2年抑草效果达87%~98%;鼠茅组第1年抑草效果达93%~94%,第2年抑草效果达98%;鼠茅组抑草率高于白三叶组。冬季护绿实验,发现鼠茅比白三叶更适宜种植猕猴桃土壤条件生长。对照冬季型草坪质评标准评分,鼠茅高于白三叶。
    结论 鼠茅生草抑草效果优于白三叶,因此落叶经济林下培育鼠茅具有较好的抑草效果,且鼠茅在冬季护绿方面优于白三叶。

     

    Abstract:
    Objectives To address the issues of weed proliferation and green scarcity in economic forests during the winter season.
    Methods From 2021 to 2023, two types of grass cultivation experiments were conducted in three different locations: the Qingyuan Camellia oleifera forests, the Songyang Chinese Torreya forest, and the Liandu kiwi tree base. The objective was to compare the grass suppression effects of three different methods: clearing cultivation, Trifolium repens, and Vulpia myuros. Additionally, the winter greening effects of T. repens, and V. myuros planted in the kiwifruit base were compared, and the winter greening effects of the two were evaluated based on eight indexes: lawn density, cold resistance, disease resistance, drought resistance, green period, color, grass resistance, and management and care difficulty.
    Results The inhibitory effect of the T. repens group was obsered to range from 58% to 94% in the first year and and from 87% to 98% in the second year. The inhibitory effect of V. myuros in the first year was 93% to 94%, and in the second year, it reached 98%. The inhibition rate in the V. myuros group was observed to be higher than that in the T. repens group. The experiment on green protection in winter revealed that V. myuros was more conducive to the growth of kiwi fruit in soil conditions than T. repens. Compared with the quality evaluation standard of winter-type lawns, the score of V. myuros was found to be higher than that for T. repens.
    Conclusions The inhibitory effect of V. myuros was superior to that of T. repens, indicating that the cultivation of V. myuros under deciduous economic forests has a more pronounced inhibitory effect. Furthermore, V. myuros was found to be more effective than T. repens in providing winter green protection.
