玉米在喷施了30%乙.己水剂后植株叶片黑亮、肥大、挺刮,株高降低,下部节间缩短变粗,茎秆干物质积累增加,气生根层数与条数增加,抗倒,用量应控制在20m l/667m2,于玉米拔节初期喷施为佳。乙烯利对植株有明显的矮化,促早熟作用,对植株的综合调控能力弱。己酸二乙氨基乙醇酯对植株综合调控能力较强,但对株高的调控能力弱。
After sprayed with 30% B, the leaves of the plants were black and bright, hypertrophy and scrape, the plant height was reduced, the lower internodes shortened and thicken, the dry matter accumulation of stalks increased, the number and number of aerial root layers increased, Anti-down, dosage should be controlled at 20m l / 667m2, sprayed at the early stage of corn jointing better. Ethephon obvious dwarf plants, and promote early maturity, the ability of comprehensive regulation of plants is weak. Caproic acid diethylaminoethanol ester has strong ability of comprehensive regulation of plants, but has weak ability of plant height regulation.
