四种新型水溶肥料对一串红生长及开花的影响

Effect of Four Types of New Water-soluble Fertilizers on the Growth and Flowering of Sagebrush

以一串红为试材,对4种新型水溶肥料在一串红生产上的应用效果进行分析,以筛选出适合一串红生产应用的新型水溶肥料种类。结果表明:喷施4种新型水溶肥料与对照相比,能明显改善一串红的营养生长,表现为叶色浓绿,生长健壮;花色鲜艳,花序多,小花多而大,能明显提高其观赏效果;提早开花时间,延迟败花时间,使得一串红花期延长,增加观赏时间。其中以喷施腐殖酸水溶肥料效果最好。建议一串红生产上推荐使用腐殖酸水溶肥料,花期长,观赏效果好。

Taking sagebrush as material,the analysis was carried out to find four new water-soluble fertilizers＇ respective effect on the production of sagebrush and which one works best.The results showed that compared with the control,spraying the four types of new water-soluble fertilizers could distinctly improve the vegetative growth of sagebrush,leaves were deep green and grew well;flowers were bright-colored and with many inflorescences and a lot of big florets,which could obviously enhance its ornamental effect;the flowering time was advanced while the withering time was postponed so that the flowering period and viewing time were both lengthened.The result also showed that spraying humic acid watersoluble fertilizer produced the best effect.Therefore,humic acid water-soluble fertilizer was recommended to be applied to the production of sagebrush to have longer flowering period and better ornamental effect.
