不同种类化肥与生物菌肥配合施用对生姜生物性状和产量的影响初报

Effects of Different Kinds of Chemical Fertilizers and Biological Fertilizers on the Biological Properties and Yield of Ginger

摘要: 为了提高唐山地区生姜的生物性状和产量，促进肥料在田间安全高效的应用，笔者于2017年进行不同种类化肥混施生物菌肥试验。结果表明，海法钾宝混施菌肥后生姜的植株生理指标比单施肥料均有增加，撒可富混施菌肥后生姜叶片对强光的耐受性增强，Fv/Fm比值达到0.57；除硫酸钾以外，其他混施生物菌肥的生姜产量均比之前有所提高，其中撒可富混施菌肥后产量比混施前增加14.00%，而硫酸钾混施菌肥后比混施前下降15.13%；撒可富与菌肥混施后产量最高，比对照增产38.97%，呈差异显著，其次为海法钾宝混施菌肥，比对照增产37.27%。因此，选取撒可富或海法钾宝混施生物菌肥，均有利于提高生姜的整体生长势、增加生姜产量，硫酸钾则不适宜与生物菌肥混用。

Abstract: In order to improve the biological properties and yield of ginger in Tangshan, and promote the safe and efficient application of fertilizer, the author conducted experiments on the mixed application of biological fertilizer with different types of fertilizers in 2017. The results showed that the physio-logical indexes of ginger in Haifa after mixed were higher than those of single application. The tolerance to strong light of ginger leaves with sakefu compled fertilizer (SACF) mixed fungus fertilizer increased, with Fv/Fm ratio of 0.57. In addition to potassium sulfate, the yield of ginger mixed with other biological fertilizer was higher than before, among which the yield of SACF after mixed biological fertilizer increased 14.00% than before, but the yield of potassium sulfate mixed biological fer-tilizer decreased 15.13% than before, which could not reach the goal of increasing the efficiency. The yield of saffron mixed biological fertilizer was higher than that of the control, yielding 38.97%, showing significant differences, followed by the Haifa mixed biological fertilizer, yielding 37.27% more than the control. Therefore, the Saffron and Haifa which mixed biological fertilizer, are all conducive to improve the overall growth potential of ginger, increasing ginger production, while potassium sulfate is not suitable for mixing with biological fertilizer.
