本研究在前几年试验筛选的基础上,选用6种包衣剂进行田间试验,其结果表明:用6种包衣剂分别进行玉米种子包衣,均比对照增产。产量位次为包衣剂6号、包衣剂11号、增产菌、包衣剂8号、多元微肥、锌肥和对照。各处理与对照相比增产幅度依次为11.29％、9.58％、7.32％、2.26％、1.8％和1.59％。其中包衣剂6号、包衣剂11号与对照达极显著水平,增产菌与对照达显著水平。试验结果还看出:其增产作用在苗期表现为有效地促进幼苗生长、根系发育、物质积累和叶面积增加;在收获期表现为各经济性状间协调与发展。苗期生长发育良好是后期改善经济性状、增加籽粒产量的前提和基础。
Based on the screening tests of the previous years, six kinds of coating agents were selected for field experiments. The results showed that the seed coating of corn seed with six kinds of coating agents all increased yield compared with the control. The yield of the coating agent No. 6, No. 11 coating agent, increased bacteria, coating agent No. 8, micronutrient, zinc and control. Compared with the control, the increment rate of each treatment was 11.29%, 9.58%, 7.32%, 2.26%, 1.8% and 1.59% respectively. The coating agent No. 6, coating agent No. 11 and the control reached a very significant level, increased production of bacteria and control reached a significant level. The results also showed that the increase in yield at the seedling stage was effective in promoting seedling growth, root development, material accumulation and leaf area increase; at the harvesting stage, it showed the coordination and development of various economic traits. Good seedling growth and development is to improve the economic traits later, increase grain yield on the premise and foundation.
