硅钙钾镁肥对果蔗产量品质及经济效益的影响

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

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。

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.
