矮壮素98% 原药.使用浓度3000ppm.这个要稀释多少水啊.1000斤水要放多少药.是怎么算的.这是给枣树上喷

Effects of chlorocholine chloride (CCC)(矮壮素) on photosynthetic characteristics,transport and distribution of photoassimilates of Zhongshu 3(中薯3),a potato (Solanum tuberosum L.) variety widely cultivated in south China,were studied by foliar 1.5 g L-1 CCC application after pot planting virus-free plantlets at the stage of budding.It was found that at the stage of tuber bulking,spraying CCC plays a prominent regulating role in the photosynthesis of Zhongshu 3.The net photosynthetic rate (A),stomatic conductance (gs),intercellular CO2 concentration (Ci) and transpiration rate (E) of leaves were superior to those of the control.CCC markedly increased the contents of chlorophyll and carotenoid.CCC significantly increased the leaf photosynthetic productivity and improved economic yield (EY).CCC increased 14C photoassimilates radioactivity distribution percentage in tuber.The leaf 14C photoassimilates assimilation with CCC treatment increased 39.7% than that of the control.And the leaf transportation percentage of 14C photoassimilates was 14.6% increased.The 14C-soluble sugar distribution percentage of CCC treatment in leaf and stem were less than those of the control,respectively,but the 14C-soluble sugar distribution percentage of CCC treatment in tuber and root were more than those of the control,respectively.The 14C-starch distribution percentage of CCC treatment in leaf,stem and root were less than those of the control,respectively.but the 14C-starch distribution percentage of CCC treatment in tuber was more than that of the control.The radioautography also indicated that photosynthate transport from top tissues to tubers was faster in CCC treatment than that in control.These results showed that appropriate concentrations at 1.5 g L-1 of CCC significantly improved the photosynthetic characteristics,transport and distribution capability of photoassimilates in potato,and as a result tuber yield would be increased.The pattern of translocation shown is held to reflect the activities of the various metabolic sources and sinks,the activities of these sources and sinks being hormonally controlled.

（2014•福建模拟）科学家研究赤霉素和矮壮素（植物生长调节剂）对黄芩（一种药用植物）生长情况及其根细胞中黄酮类物质（主要药用成分）含量的影响．把生长状态一致的幼苗平分为三组进行不同处理，26天后检测结果如下表所示，由此可知（　　）

黄芩的生理指标	对照组	实验组处理
		喷施矮壮素	喷施赤霉素
株高（cm）	20.540	21.460	27.520
地上部分重量（g）	0.295	0.382	0.364
地下部分重量（g）	0.100	0.053	0.047
根样品中黄酮类成分含量（mg/g）	210.450	146.293	209.270

A．甘薯等块根类植物不适合施用矮壮素和赤霉素
B．矮壮素提高黄芩光合作用强度的效果好于赤霉素
C．矮壮素对黄芩产生黄酮类成分不利，赤霉素有利
D．外源喷施赤霉素比黄芩合成的赤霉素对植株增高更有效
