摘　　要：薇甘菊发生区域的新造林地极易受到薇甘菊的侵袭、危害,为了寻找成本低廉、防效显著的薇甘菊控制技术,受森林郁闭度大于70%时薇甘菊难以生存且对周围其他植物不造成危害的自然现象启发,选择不同透光率的黑色塑料膜、三层遮阳网、二层遮阳网、一层遮阳网、黄色塑料膜、蓝色塑料膜,在薇甘菊发生较为严重的瑞丽市进行人工模拟郁闭、遮荫控制薇甘菊试验。结果表明,黑色塑料膜覆盖薇甘菊的透光率为0%,30d后能够迅速降低薇甘菊盖度至0%,降低薇甘菊生物量,致使薇甘菊花序数量为0个,影响其植株生长发育,导致薇甘菊迅速死亡;因此,黑色塑料膜是对薇甘菊速效郁闭、遮荫控制的最佳候选材料。The new planted forest is vulnerable to mikania micrantha occurrence areas.It is difficult to survive and can’t harm other plants when the forest canopy density is more than 70%.In order to find low cost,significant control effect of mikania micrantha control technology,six kinds of materials with different light transmittance were adopted to take shading treatment for Mikania micrantha which was serious in Ruili.The control effects of yellow and blue plastic greenhouse films,one-layer and two-layer sunshade net were inferior to black plastic greenhouse film and three-layer sunshade net.With investigation and analysis on the inflorescence number,coverage and other indexes of Mikania micrantha,it obtained that using plastic greenhouse film and sunshade net to cover Mikania micrantha could affect its growth,wherein the light transmittance of black plastic greenhouse film was 0%.After 30 days of sun shading,the blossom and fruition amount was 0.Hence,the black plastic greenhouse film is the best candidate material for artificial quick closure and shade control of Mikania micrantha.
