一、助壮素是什么农药 助壮素是一种新的棉花生育促控制。它的化学名称叫1,1—二甲基哌啶鎓氯化物,商业名称PiX,俗名助壮素。它是白色晶体,熔点285℃,无味,易溶于水,性质稳定,密封保存于干燥阴凉的地方,至少两年不会丧失药效。毒性低,使用安全。喷雾由叶面吸收,在土壤迅速分解。目前由沈阳化工研究院、天津农药厂生产供应。 二、棉花喷助壮素的作用与效果 助壮素能抑制棉株营养生长,使主茎和果枝节间缩短,株型紧凑,通风透光良好,光合作用增强。据我院在喷药后一个月用SH型红外线CO_2分析器测定,棉株上部主茎叶光合强度较对照增加4.35—8.27毫克CO_2/平方分米·时。由于助壮素能控制棉
First, what is a mellitus What is a pesticide mellitus is a new cotton growth control. Its chemical name is 1,1-dimethylpiperidinium chloride, under the trade name PiX, commonly known as mepiquatosin. It is a white crystal, melting point 285 ℃, tasteless, soluble in water, stable in nature, sealed and stored in a dry and cool place, at least two years will not lose efficacy. Low toxicity, safe to use. The spray is absorbed by the foliage and rapidly decomposes in the soil. At present, Shenyang Chemical Research Institute, Tianjin Pesticide Factory production and supply. Second, the role of cotton spit and help the role of cortisone and help mellitus can inhibit the vegetative growth of cotton, so that the main stems and fruiting branches internode shortened, plant compact, good ventilation and enhanced photosynthesis increased. According to our hospital in a month after spraying with SH-type infrared CO_2 analyzer measured, the upper part of the main plant leaf photosynthetic fiber increased by 4.35-8.27 mg CO_2 / dm · ·. As help mellitus can control cotton
