ZT-1丰抗素对覆膜玉米的增产作用研究

Study on Yield-increasing Effect of ZT-1 Abundant Antibiotic on Film-mulched Corn

以覆膜玉米为试材,在播种前用ZT-1丰抗素8 000倍液拌种处理,开展了ZT-1丰抗素对覆膜玉米植株性状、产量性状及单位面积产量的影响试验。结果表明,拌种处理后,覆膜玉米株高较清水对照增高15.2 cm,增幅6.63%;每株结双穗的植株占38.9%,较清水对照增加25.76%;穗长增加16.87%;穗粗增加9.38%;穗轴重增加28.75%;百粒重增加8.36%。小区(20 m^2)平均产量提高3.26 kg,折合产量提高1 630 kg/hm^2,增幅13.28%。由此表明,ZT-1丰抗素拌种可以显著提高覆膜玉米产量。

Film-mulched corn covered with plastic film was treated with 8 000 times ZT-1 Abudant antibiotic before sowing,the experiment was conducted to study the effects of ZT-1 Abudant antibiotic on plant traits,yield traits and yield per unit area of film-mulched corn.The results showed that after seed dressing,compared with the control,the plant height of film-mulched corn increased by 15.2 cm,and the growth rate was 6.63%.The percentage of plants with double spike was 38.9%,which increased by 25.76% than that of control,and the ear length increased by 16.87%.The ear diameter increased by 9.38%,the cob weight increased by 28.75%,and the 100-grain weight increased by 8.36%.The average yield of the experimental area(20 m^2)increased by 3.26 kg,equivalent yield increased by 1 630 kg/hm^2,and the growth rate was 13.28%.Therefore,it showed that ZT-1 Abudant antibiotic could significantly increase the yield of film-mulched corn.
