生长调节剂浸根对当归温室苗出苗及生长进程的影响
Effects of Growth Regulator Root-soaking on Greenhouse-cultivated Angelica Seedlings Emergence and Growth Progress
摘要
Abstract
Objective:To break the dormant state of greenhouse-cultivated angelica seedlings and promote its emergence and growth progress by means of growth regulator.Methods:With greenhouse-cultivated angelica seedlings as materials,3 factors 4 levels orthogonal test was designed,different concentration gradient mixture solution of gibberelhn (GA3),diethyl aminoethyl hexanoate (DA-6) and naphthylacetic acid (NAA) was used to soak root when transplanting,the emergence dynamics was monitored in emergence period,the stem-leaf morphological index and bolting rate were measured in stationary growth stage,the root morphological index and yield were measured in harvest time.Results:GA3,DA-6 and NAA had highly significant effects on emergence rate of greenhouse-cultivated angelica seedlings,the order of effects was GA3 ＞ DA-6 ＞ NAA;the emergence rate and yield of greenhouse-cultivated angelica seedlings were correlated with GA3 at 0.01 level significantly,but they weren't correlated with DA-6 and NAA.Conclusion:The reagent combination of GA3,DA-6 and NAA could break the dormant state of greenhouse-cultivated angelica seedlings and promote its emergence and growth progress significantly;the optimal reagent combination screened for root-soaking of greenhouse-cultivated angelica seedlings when transplanting was 96.00 mg ·L-1 GA3,20.26 mg ·L-1 DA-6,53.12 mg ·L-1 NAA,the emergence rate of greenhouse-cultivated angelica seedlings was 83.75％,the yield of angelica was 363.22 kg ·666.7 m-2.关键词
