摘　　要：以绿豆品种绿丰2号为试验材料,以研制的绿豆专用型种衣剂包衣为处理,以常规大豆种衣剂(CK1)及微生物种衣剂包衣(CK2)为阳性对照,以未进行包衣的空白种子为阴性对照(CKW),测定其对绿豆形态指标与光合特性的影响。结果表明:运用适宜浓度(活性成分用量分别为100%(Z3)、125%(Z4))的绿豆专用种衣剂可有效增加绿豆总叶绿素含量与净光合速率(二者均显著高于对照CK0、CK1及CKW)、气孔导度(Z3处理高于各对照46.97%~84.82%,达极显著水平),改善光合性能;与常规大豆种衣剂包衣相比降低绿豆株高0.20~1.63 cm,茎粗提高2.07%~6.74%,根长以及侧根数分别增加14.85%~20.30%与11.81%~27.57%,进而调控绿豆苗期地上地下干物质积累与植株形态,确保绿豆苗期健康生长。In this work,the morphological indexes and photosynthetic characteristics of mung bean plant were studied using variety“Lufeng 2”that the seeds coated by a mung bean-specific seed coating agent developed by our laboratory.Regular and microbiological soybean seed coating agents were used as positive controls,and uncoated seed was used as negative control.The results showed that the mung bean-specific seed coating agent with suitable concentrations(100%(Z3)and 125%(Z4)active ingredients)can effectively enhance the photosynthetic performance through increasing the chlorophyll content and net photosynthetic rate(both are significantly higher than various controls,such as CK0,CK1 and CKW)as well as stomatal conductance(Z3 was extremely significantly higher than the various controls at least by 46.97%~84.82%).Compared with the advantage control(regular soybean seed coating agent),it also decreased the plant height more than 0.20~1.63 cm,increased the stem diameter,root length,and number of lateral roots at least by 2.07%~6.74%,14.85%~20.30%,and 11.81%~27.57%,respectively.Thereby,regulating the above-ground and below-ground dry mass accumulation and the plant morphology of mung bean seedlings,and ensuring the healthy growth of the mung bean seedling.
