生物菌肥在玉米上的应用效果研究

Effect of Bacterial Manure Applicated to Maize

通过采用拌种、浸种、叶面喷施 3种处理方式在玉米品种上使用中合牌生物菌肥的试验结果表明 :① 3种处理对玉米的籽粒产量和主要农艺性状都有一定的促进作用 ;其效果依次为拌种、浸种、叶面喷施。②玉米施用该菌肥后 ,气生根比CK(不施 )增加 1～ 2层 ,大大提高了玉米品种的抗倒能力。③玉米在抗病性、经济性状、植物学特征、生物学特性等方面均表现比CK优良。④不同菌肥处理水平对籽粒营养品质均有一定的影响作用 ,蛋白质含量、脂肪含量、淀粉含量。

The influence of using 'Zhonghe' brade biological bacterial manure upon four maize varieties was studied by three treatment ways of seed dressing,seed soaking and spracing on leaves. The results showed that: ①The maize yield and main agronomy characters all improved by three treatments. The effects order isseed dressing, seed socking, spracing on leaves. ②Being used the bacterial manure on maize,the air roots increase 1～2 layers than CK(not using the manure).The ability of logding resistance is greatly increased. ③The maize used the manure is better than CK on the disease resistance, economy character, botang characteristic, biology characteristic etc.. ④Bacterial manure of different treatment level have influence on nutritive quality of grains. The content of protein,fat,starchin grains are increased obviously than CK.
