摘要
小麦拔节期叶面喷施麦业丰结果表明 ,成穗数和穗粒数随喷施浓度增高有一定降低 ,并能有效降低基部节间长度 ,但对株高没有影响 ,从而增强了小麦抗倒能力 .原剂型 375～ 75 0ml/hm2 处理增产 6 .8%～ 11.2 % ;新剂型 375ml/hm2 处理增产 14.2 % .麦业丰拌种试验表明 ,高浓度麦业丰拌种 ,可抑制小麦出苗和降低株高 ,影响产量 。
With spray of Mai Yefeng onto the leaves of wheat at its shooting period, the number of ears and their grains decrease as the consistency increases. The leaf praying can also effectively shorten the joint length and improve the collapse resistant capacity; while it has no effect on the height of wheat. With the use of primary type at 375～750 ml/hm 2, the yield can be increased by 6.8%～11.2%; while the use of the new type at 375 ml/hm 2 can increase the yield by 14.2%. The test of seed dressing with Mai Yefeng shows that it hinders the emergence and lower the plant height and adversely affects the yield but increases the dry weight of wheat's main organs if the consistency is high.
