生姜是生长期较长且需肥量较高的作物,长期以来,人们在生姜栽培上多注重氮、磷、钾肥的投入,而在生姜生产上关于硅肥施用的研究报道并不多,当前的试验结果表明:施用适宜量的硅肥,可以促进生姜的生长,提高生姜的产量。设施模式下增产率为26.7%;地膜小拱棚模式下增产率为23.6%。当施硅量超过90.0 kg/亩时,2种种植模式下生姜产量均不同程度下降,其中设施种植模式下产量下降10.8%,地膜小拱棚种植模式下产量下降8.9%。由此可见,施用过量的硅肥反而不利于生姜产量的提高,平度地区高产田硅肥施用量每亩应控制在90.0 kg左右。
Ginger is a long-growing and high-yielding crop. For a long time, people pay more attention to the investment of nitrogen, phosphorus and potassium in ginger cultivation. However, there are not many reports about the application of silicon fertilizer in ginger production. Currently, The results show that: the application of the appropriate amount of silicon fertilizer, can promote the growth of ginger, ginger production increased. The rate of yield increase was 26.7% under the mode of operation and the increase rate of yield was 23.6% under the mode of plastic film small archway. When the amount of silicon was more than 90.0 kg / mu, the yield of ginger in two planting modes all decreased to different extents, among which, the output of planting under planting mode decreased by 10.8% and the yield of planting under the mode of plastic film shed was reduced by 8.9%. Thus, the application of excessive silicon fertilizer is not conducive to the improvement of ginger production, Pingdu high-yield silicon fertilizer application per mu should be controlled at about 90.0 kg.
