研究40%羟烯·乙烯利水剂在玉米上的应用效果,结果表明:在玉米七至十三叶期喷施40%羟烯·乙烯利水剂可以使玉米籽粒饱满、成熟度好、百粒重增加等;并矮化株高10~30 cm,根系发达,增强抗倒伏能力;增产508.8 kg/hm2,增产幅度5.3%,纯增收1 065元/hm2,增产增收效果明显。其中七至八叶期可以使用225~450 g/hm2剂量,九至十三叶期使用450 g/hm2剂量,但应慎用超过900 g/hm2的使用剂量。
The results showed that the application of 40% hydroxyethyl ethylene dianhydride on corn was studied. The results showed that the application of 40% Increase the height of dwarfing plants by 10-30 cm, develop root system and increase lodging resistance; increase yield by 508.8 kg / hm2 and increase yield by 5.3%; increase net income by 1,065 yuan / hm2 and increase production and income increase obviously. In the seven to eight-leaf period 225 to 450 g / hm2 can be used and in the nine to ten-leaf period 450 g / hm2 to be used, but dosage levels exceeding 900 g / hm2 should be used with caution.
