玉米健壮素是一种复配的植物生长调节剂,在玉米上使用能改变株型,增强抗倒能力,有助于提高种植密度,增加产量。现将其应用效果和使用技术简介如下: (一)对玉米生育的影响 玉米喷施玉米健壮素后,能迅速抑制玉米节间的伸长,使节间明显缩短。如总叶片数为20～21的苏玉2号,在8～10叶展开期喷施,主要缩短果稳以下各节位,在12～14叶展开期喷施,主要缩短果穗以上各节位。据1985年试验,苏玉2号喷施玉米健壮素的,比对照株高缩短64.1厘米,穗位下降27.1厘米;
Cornstarch is a compound of plant growth regulator, used on corn can change the plant type, enhances the ability of lodging resistance, helps to increase the planting density, increase the yield. Now the application of the results and the use of technology are as follows: (a) the impact on maize growth Maize spraying corn hormone, the corn can quickly inhibit internode elongation, internode significantly shortened. For example, Suyu No. 2 with a total number of leaves of 20-21 was sprayed at 8-10 leaf expansion stages, mainly shortening the nodes below the fruit firmness and spraying on the 12-14 leaf expansion stage, mainly shortening the nodes above the ear . According to the test in 1985, Su Yu 2 spray corn healthy hormone, shorter than the control plant height 64.1 cm, ear reduction 27.1 cm;
