我市棉铃虫防治总指挥由市委书记担任,市委狗芽根又称拌根草、马绊草、草板筋、铁线草,是多年生禾本科杂草,喜湿耐早,抗盐碱,以匍匐茎和种子繁殖,匍匐茎发达,可长达1-2米。节间短,节下生根,两侧生芽,种子可随风和水流传播,扩展很快。全国分布很广,在田边、地埂、果园、林带,成片分布,危害作物,难以防除。本次试验采用灭生性传导型茎叶处理剂草甘膦,可干扰体内苯丙氨酸及酪氨酸的合成,并使细胞染色体失常,使茎、地下根中毒,失去再生能力。这种杂草一般除草剂难以防除,在农田应用草甘麟,喷雾对作物易产生药害,本次试验采用涂抹施药法。涂抹施药法,将内吸传导型除草剂涂抹在杂草的植株上,通过茎叶吸收传导,使药剂进入植物体内,以致达到根部。这是最省药最经济的施药方法之一,用具简单,用药不会产生飘移与污染环境,对施药人员十分安全。(一)材料和方法1.试验地点吐鲁番市胜金乡林场葡萄园2.施药时期狗牙根少部分植株开始开花,生长旺盛,100m~2有1 600株。本次试验在8月18日进行的。3.供试药剂、药量 10%草甘膦水剂,江苏化
The city’s cotton bollworm prevention and control of the commander by the municipal party committee secretary, municipal dog dog bud root, also known as the root of grass, horse tripped grass, grass tendon, wire grass, perennial grass weeds, wet dawn, salinity, To stolons and seeds breeding, stolons developed, up to 1-2 meters. Internodes are short, rooting under the node, germinating on both sides, the seeds can be spread with the wind and water flow, expanding rapidly. The country is widely distributed in the fields, land 埂, orchard, forest belt, into a piece of distribution, hazardous crops, it is difficult to control. In this experiment, the biomimetic conduction-type stem and leaf treatment agent glyphosate can interfere with the synthesis of phenylalanine and tyrosine in the body and cause cell chromosomal abnormalities, causing the stems and underground roots to be poisoned and lose their regenerative capacity. This weed is generally difficult to control the herbicide, glycyrrhizin in the field application, the spray easy to produce phytotoxicity of crops, this test using the smear application method. Apply smear application method, the absorption-type herbicide applied to weeds in the plant, absorbed through the stems and leaves conduction, so that agents into the plant, so as to reach the roots. It is one of the most economical and economical ways to administer medicine. With simple appliances, medication will not drift and pollute the environment, and it is very safe for drug applicators. (I) Materials and methods 1. Test site Vineyard in Shengjinxiang Forestry Farm, Turpan City 2. A small number of plants of Bermudagrass began to bloom in the period of application, with vigorous growth. There were 1 600 plants in 100m ~ 2. The test was conducted on August 18. 3. For test agents, dosage of 10% glyphosate agent, Jiangsu
