为探讨叶面宝对玉米生长和产量的影响，进行了不同浓度药剂浸种和拌种处理的田间试验。结果表明：采用不同浓度叶面宝浸拌种都可不同程度地提高玉米产量，１０００倍液、２０００倍液、４０００倍液浸种和２００倍液拌种处理较对照分别增产１７．９％，７．４％，３．０％和１６．７％，１０００倍液浸种和２００倍液拌种的增产效果达到显著水平。同时，用叶面宝液浸拌玉米种子可提高发芽率，促进苗期生长和植株干物质积累
In order to investigate the effect of YeBao on the growth and yield of maize, field experiments were carried out on soaking seeds and seed dressing with different concentrations of chemicals. The results showed that the corn seedling yield could be increased to different extent by using different concentrations of Baofeng Baimian seed dressing. The seed yield of 1000 times, 2000 times, 4000 times and 200 times seed dressing increased 17.9% and 7.9% respectively compared with the control .4%, 3.0% and 16.7%, 1000 times soaking seeds and 200 times seed dressing yield increase reached a significant level. At the same time, soaking the corn seeds with the liquid of the foliar leaves can increase the germination rate and promote the seedling growth and plant dry matter accumulation
