在甘薯生长过程中,控制其茎蔓的旺长,对提高薯块的产量和品质起着关键的作用。目前甘薯生产上多采用多效唑控蔓,但研究发现,采用多效唑控蔓存在不少缺陷:一是多效唑的残效期较长,易影响后在作物生长,而且会导致农产品农残超标;二是多效唑只能控制顶芽、侧芽生长点的生长,不能抑制茎蔓不定根的生长,对甘薯增产效果不显著。二甲戊灵是旱作物田选择性除草剂,该药除作为除草剂使用外,近些年在烟草生产中也作为植物生长抑制剂而被广泛使
In the process of sweet potato growth, the control of its vine length of Wang, to improve the yield and quality of potato plays a key role. At present, the production of sweet potato is dominated by paclobutrazol. However, studies have found that the use of paclobutrazol has many defects: firstly, the residual effect of paclobutrazol is longer, and it is more likely to affect the growth of crops and cause excessive pesticide residues; secondly, paclobutrazol Can only control the top buds, lateral bud growth point of growth, can not inhibit the adventitious root growth, the sweet potato yield is not significant. Pendimethalin is a selective herbicide for dry crop fields. In addition to its use as a herbicide, it has also been widely used as a plant growth inhibitor in tobacco production in recent years
