硅钙钾镁肥对果蔗产量品质及经济效益的影响

在大田试验条件下研究了不同用量硅钙钾镁肥对果蔗产量、品质等的影响,结果表明:施用硅钙钾镁肥能显著提高果蔗产量,产量增加6.6%~17.4%,施用量在T3处理1500 kg/hm2时产量达到最高,差异显著。蔗糖含量、茎长、节长、茎粗等随硅钙钾镁肥用量增加呈增加趋势,在T3处理时达到最佳,蔗糖含量提高了9.3%。施用硅钙钾镁肥不仅可以提高产量、改善品质,而且可以改良蔗田土壤状况,土壤p H值调高了0.09~0.80。

Effects of Silicon-Calcium-Potassium-Magnesium Fertilizeron on Yield,Quality and Economic Benefit of Chewing Cane

The field experiments were conducted to study their effects on yield, quality and economic benefit of chewing cane, on the basis of different levels of silicon-calcium-potassium-magnesium (SCPM) fertilizer. The results showed that the application of SCPM fertilizer obviously increased the yield of chewing cane, the yield increased by 6.6%~17.4%, compared with the CK treatment. Application amount of 1500 kg/hm2 in T3 treatment, the yield reached the highest output and had significant difference. Sucrose content, stem length, section length, stem diameter etc, showed a trend of increase with the increase of application amount of SCPM fertilizer, T3 treatment to achieve the best effect and sucrose content increased by 9.3%. Applying SCPM fertilizer could not only increase yield, improve quality, but also improve sugarcane field soil conditions; the pH value of the soil in the treatments of applying SCPM fertilizer raised by 0.09~0.80.
