EM包衣对玉米种子出苗率及产量的影响

摘要

为充分合理利用有效微生物群（EM ），采用随机区组的方法，研究了不同浓度EM 对玉米出苗率和产量的影响。结果表明：不同浓度EM对玉米出苗率有显著影响，EM70处理出苗率最高为87．33％，EM10处理出苗率最低为76．45％；EM对玉米株高没有显著影响；不同浓度EM 对玉米产量有显著影响，其中EM70处理产量最高为11225 kg・hm‐2，比对照增产12．47％，EM100产量最低为10340 kg・hm‐2，比对照增产3．61％。%　　The effect of EM seed‐coating on the rate of emergence and yield of Zea mays were studied by the method of random block to make full use of effective microorganisms .The results showed that different EM concentration had significant effects on the rate of emergence ,germination rate of EM 70 was up to 87 .33% , EM10 were the lowest for 76 .45% ;EM had no significant effect on maize plant height ;The different concen‐tration of EM had significant effect on maize yield ,EM70 yield was the highest for 11 225 kg・hm‐2 ,increased by 12 .47% compared with the control ,the EM100 yield was the lowest for 10 340 kg・hm‐2 ,increased by 3 .61% compared with the control .
