随着刺梨研究的深入和发展,刺梨园地需集中大量劳力进行人工除草,估计每除一亩地一次花10～13个,三次花30～40个,计价一亩45～60元,一个园区以50亩计,将花2250～3000元投资增大几倍到十几倍。为此,刺梨园区的除草成了急待解决的问题,本文特选用草甘膦等除草剂进行小区和较大面积的试验示范,结果表明:百草枯、草甘膦等除草剂的除草效果极显著,防除等级8.6～10级,即防效达86～100％,可节省投资60～90％以上,现将结果总结如下: With the further research and development of prickly pear, prickly pear orchard need to concentrate a lot of labor for artificial weeding, it is estimated that every time you spend an acre of 10 to 13 flowers, flowers 30 to 40 three times a meter 45-60 yuan per acre, a Park to 50 acres, will spend 2250 ~ 3000 yuan investment increased several times to ten times. Therefore, the weed cultivation in Cili pear area has become an urgent problem to be solved. In this paper, glyphosate and other herbicides were selected to test plots and large areas. The results showed that the herbicidal effects of herbicides such as paraquat and glyphosate Very significant, the level of control 8.6 to 10, that is, anti-efficiency of 86 to 100%, saving more than 60% to 90%, the results are summarized as follows:
