玉米健壮素是江苏省淮阴农业科学研究所研制的一种植物生长调节复配剂。经本区1987、1988连续两年的多点试验和大面积生产示范结果表明,对玉米有明显的增产效果。一、降低株高、穗位高:用玉米健壮素在玉米植株叶龄指数55—60％时期喷施,可有效地缩短穗位节上下四个节间的长度,使玉来植株的抗倒伏能力显著增强。试验表明,施用玉米健壮素后,玉米植株高度降低35％,穗位高度降低37％。这种矮化作用,对解决肥力水平高和当风的田土玉米倒伏问题效果良好,可以确保这些田土玉米稳产,高产。二、增苗、增穗、增产量:玉米健壮素大幅度提高玉米产量的一个前提是必须加大玉米的种植密度。据试
Corn Jian Su Sui is the Jiangsu Provincial Institute of Agricultural Sciences developed a plant growth regulator compound. After 1987,1988 in this area for more than two consecutive years of multi-point test and large-scale production demonstration results show that corn yield significantly increased. First, to reduce plant height and ear height: with corn healthy hormone in the corn plant leaf age index of 55-60% spraying period, can effectively shorten the length of the upper and lower ear section four internodes, jade plant lodging Significantly increased ability. The results showed that the corn plant height was reduced by 35% and the ear height decreased by 37% after application of cornstarch. This dwarfing effect, to solve the high level of fertility and wind when the corn field lodging effect is good, to ensure that these fields corn stable yield, high yield. Second, by Miao, Zeng Sui, increase production: Ma Jian Su substantial increase of corn production is a premise must increase the planting density of corn. According to test
