植宝素对黑珍珠穗醋栗产量结构的影响

Influence Of Applying "ZHIBAOSU" On Yield Constructions Of Benlomond Currant

本文主要研究了植物生长调节剂植宝素对黑珍珠穗醋栗(Benlomond)所产生的效应。通过植宝素三种浓度(7000,9000和11000倍)的喷雾试验可知,黑珍珠花果主要物候期(开花前期、果膨大期、果着色期)中,无论采用单期喷或三期连喷,均起到促进增产和改进品质的作用。从全面衡量看,以三期连喷效果最佳,采用9000倍药液喷雾效果最好,可在生产上应用。

The effects of the plant growth regulator, ZHIBAOSU, on Benlomond Currant were studied. Three kinds of concentrations (7000 ,9000 , and 11000 ) of the regulator were sprayed in the major periods of the currant's flower and fruit development(pre - bloom period, berry growing period and berry colouring period). Results showed that whether spraying in a single period or at the three periods successively the berry yield and quality can be increased and improved, respectively. Considering all -round aspects, successively spraying in the three periods, by the concentration of 9000 * , created the best effect, and can be applied in production.
