从豫西苹果园不同生态系划分入手,通过系统调查和田间观察,将豫西苹果园杂草发生划分为四种类型区,初步鉴定查明豫西苹果园杂草分布于33科102属132种,主要恶性杂草及优势种为大碱草、白茅、莎草、小旋花、播娘篙、小蓟、茵陈篙、狗尾草等。并在摸清主要恶性杂草生物学特性的基础上,研究了一套行之有效的防除技术。结果表明,在杂草幼苗期用10％草甘膦水剂22.5～30L·hm~(-2)与JFC渗透剂、硫酸铵、洗衣粉等混用,可有效地防除果园深根系杂草大碱草、白茅、莎草、小蓟等;采用20％克芜踪和10％草甘膦复配或单用克芜踪进行二次用药,可有效地控制果园阔叶杂草的发生。
Starting from the classification of different orchards in western Henan apple orchard, the weed occurrence in western Henan apple orchard was divided into four types by systematic investigation and field observation. The preliminary identification indicated that the weeds in western Henan apple orchard were distributed in 132 families of 33 families Species, the main malignant weeds and dominant species of Siberian Habitat, white grass, sedge, small convolvuli, sowing motherwort, thistle, capillaris, Setaria and so on. Based on the study of the biological characteristics of the major malignant weeds, a set of effective control techniques was studied. The results showed that the mixture of 10% glyphosate agent 22.5 ~ 30L · hm -2 with JFC penetrant, ammonium sulfate, detergent and so on can effectively prevent and control the weeds in the orchard Grass, prunus mongolica, sedge, thistle, etc .; secondary use of 20% g Wuzuo and 10% glyphosate alone or with cinnabar trace can effectively control the occurrence of broad-leaved orchard weeds.
