玉米健壮素是江苏淮阴地区农科所研制的一种新型植物生长调节剂。具有调节植物新陈代谢,抑制植物生长,降低植株高度,防止茎叶早衰,提高亩产量等作用。且成本低,效益高,每亩投入0.6元,便可获得21～30元的经济效益。我们于1990～1991年引进并在寿光、临朐、坊子三县7个乡镇56个点进行试验大面积示范。结果表明:喷施健壮素的玉米,植株矮健敦实,茎节变短,支持根增多,抗伏能力增强。株高平均降低53.5～56.7厘米,穗位降低13.8～15.5厘米,茎粗增加0.26～0.39厘米,支持根增加1.6～2.4层,单株根条数增加11.3～16.5条,每穗籽粒增加22～26粒,千粒重增加2.5～3.6克,每亩增产玉米51～63公斤,增设15％～17％左右。
Corn is a healthy element of Jiangsu Huaiyin Institute of Agricultural developed a new type of plant growth regulator. With the regulation of plant metabolism, inhibition of plant growth, reduce plant height, prevent premature aging stems, improve the yield per acre and so on. And low cost, high efficiency, 0.6 yuan per mu investment, you can get 21 to 30 yuan of economic benefits. We introduced from 1990 to 1991 and conducted a large-scale demonstration experiment in 56 spots in 7 townships of Shouguang, Linqu and Fangzi counties. The results showed that the corn with vigorous hormone was short and firm, the stem node became shorter, the supporting root increased and the anti-volt ability enhanced. The plant height was reduced by 53.5 ~ 56.7 cm on average, the ear position was reduced by 13.8 ~ 15.5 cm, the stem diameter was increased by 0.26-0.39 cm, the supporting root increased by 1.6 ~ 2.4 layers, the number of single plant root increased by 11.3-16.5, 26 grains, 1000 grain weight increase 2.5 ~ 3.6 grams, corn yield per acre 51 ~ 63 kg, an increase of 15% to 17%.
