摘要
应用3种不同的药剂对4个属7种冷季型草坪草种幼苗期的早春杂草进行化除试验,结果表明3种药剂对草坪地杂草的防除有不同的效果,并且对冷季型草坪草种幼苗期的生长也有不同的影响。其中,处理Ⅱ早春进行苗期喷雾防治,不仅对参试品种本身安全可靠,而且有一定的促长效应。该处理(Ⅱ)对阔叶性杂草的致死率达到43%,综合防效可达75%;对禾本科杂草的生长和种子萌发也有一定的抑制作用,与对照比较可减少35.8%的杂草发生。从而达到封闭和防除早春草坪杂草的双重目的。
Three kinds of chemicals were applied on the early-spring weeds with respcet to seven species belonging to four genera of cool season turfgrass seedling period.The results showed that these chemicals gave different effects on the growth of cool season turfgrass seedling and weed control.Among the turfgrass seedlings were sprayed with treatment Ⅱ during early-spring.It was secure to tested turfgrass and could promote the turfgrass growth.The treatment gave 43 % lethality and 75 % comprehensive control effect for broad-leaf weed.It also withheld the growth and seed germinating of gramineous weeds.Comparing with CK,treatment Ⅱ reduced 35.8% weed occurance and gave double effects of sealing and control weed.
