四年的系统研究证明，用生根粉４号拌、浸种，能提早出苗２天，明显地促进根系发育和地上部的生长．结果平均每穗增加２４．５～３２．４粒，千粒重提高９．７～１２．１克，每亩增产４０公斤（９％）以上，投产比为１：１００。生根粉在玉米上最好用于浸种或拌种，最适的浓度，拌种是３５～４０ｍｇ／ｋｇ，浸种是１５～２０ｍｇ／ｋｇ，最适浸种时间为８～１２小时，生根粉可以与农药和包衣剂混用。
Four years of systematic research shows that the use of rooting powder mix 4, soaking, early emergence 2 days, significantly promote root development and shoot growth. As a result, the average grain yield per ear increased from 24.5 to 32.4 grains and the grain weight was increased from 9.7 to 12.1 grams. The yield per mu was above 40 kg (9%), and the ratio of production to production was 1: 100. Rooting flour on corn is best for soaking or seed dressing, the optimum concentration, dressing is 35 ~ 40mg / kg, soaking is 15 ~ 20mg / kg, the optimum soaking time is 8 ~ 12 hours, rooting powder can be Pesticide and coating agent mixed.
