摘要
为解决贵州薏苡植株偏高易倒伏的问题,进行了多效唑、矮壮素和全锌玉状元生长调节剂对薏苡植株的矮化效果试验。结果表明:3种生长调节剂对薏苡植株均有一定的矮化作用,以全锌玉状元浸种+喷施方法(A3B3)对薏苡植株的矮化效果最好,处理后株高为156.50cm,比对照低30cm;各生长调节剂对薏苡产量的影响不同,各处理中,A1B1、A2B3、A3B2和A3B3的产量增产2.97%～52%,增产效果最好的是处理A3B3(全锌玉状元浸种+喷施),增产率达52%。
Dwarf effects of three different growth regulators,including multi-effect triazole（MET）,chlormequat chloride（CCC） and Quanxinyuzhuangyuan,were studied to prevent plant lodging due to the plant height.The results showed that all the three growth regulators had dwarf effects on C.lacryma-jobi.Quanxinyuzhuangyuan applied by soaking and spraying（A3B3） had the best dwarf effect,of which the plant height was 156.50 cm,30 cm lower than CK.All the three growth regulators had different effects on C.lacryma-jobi yield,the yields of A1B1,A2B3,A3B2 and A3B3 were increased by 2.97%~52%.A3B3 had the highest yield-increasing rate of 52%.
