观光杨梅园控草效果试验

Experiment on Weed Control Effect in Sightseeing Orchard of Myrica rubra

对观光杨梅园内主要杂草进行控草效果试验,分别采用88.8%草甘膦铵盐可溶性粉剂1798g/hm2、3596g/hm2、5394g/hm2的有效含量加水675kg/hm2喷雾,对蕨、杠板归、对白栎、空心莲子草等果园主要杂草控草效果达75.5-95.0%。对木本植物算盘子、檵木等有一定的控制效果,百草枯450ml/hm2、900ml/hm2、1350ml/hm2加水675kg/hm2喷雾,控草效果达64.8～79.3%,但蕨部分的茎干尚未枯黄,不宜于控制蕨类杂草,试验表明,88.8%草甘膦铵盐可溶性粉剂控草效果显著,可以在山地果园上推广应用。

Experiment on weed control effect in sightseeing orchard of Myrica rubra was done. When sprayed 88.8% glyphosate-ammonium soluble powder with contents of 1798g/hm2、3596g/hm2、5394g/hm2 respectively dissolved in 675kg/hm2 water on some main weeds such as Pteridophyta, Polygonum perfoliatum, Alternanthera philoxeroides, 75.5% to 95.0% of them were controlled effectively. And to some woody plants, such as Glochidion puberum, Loropetalum, when sprayed paraquat with 450ml/hm2、900ml/hm2、1350ml/hm2 respectively dissolved in 675kg/hm2 water, the control effect was 64.8% to 79.3%,but to Pteridophyta, whose caudex didn't turn yellow, it didn't work effectively. The result showed that, 88.8% glyphosate-ammonium soluble powder has an obvious weed control effect, so, it is necessary to popularize the application in hill orchard.
