施用不同复合肥对甘蔗产量与品质的影响研究

以甘蔗品种新台糖22号为试材,采用田间试验方法,探讨施用不同复合肥对甘蔗产量与品质的影响。结果表明,施用牛头牌复合肥甘蔗出苗好,生长快,蔗糖分含量高,每公斤养分产蔗茎分别比施进口复合肥和丰岭牌复合肥多82.9和113.8 kg,增幅分别达50.46%和85.31%;施用牛头牌复合肥对防治蔗地土壤酸化、改善土壤环境也有一定的作用。可见,生产同等甘蔗产量需投入牛头牌复合肥的量更少,其对土壤和水体环境污染更低,如能降低牛头牌复合肥的价格,则单位面积的经济和生态效益会更加显著。

Effects of different compound fertilizers on yield and quality of sugarcane

A filed experiment was conducted to study the effects of different compound fertilizers,viz.,Niutou compound fertilizer,import compound fertilizer and Fengling compound fertilizer,on sugarcane（variety ROC 22） yield and quality.The application of Niutou compound fertilizer resulted in highest seedling emergence rate,growth rate and sucrose content in sugarcane.The increase in cane yield was 82.9 and 113.8 kg/kg with applying Niutou compound fertilizer compared to that with import compound fertilizer and Fengling compound fertilizer,with the increasing rates of 50.46 and 85.31% respectively.The Niutou compound fertilizer also showed certain effect on prevention of soil acidification and improvement of soil conditions.It was observed that production of same sugarcane yield required less Niutou compound fertilizer compared with other compound fertilizers.Further,the use of Niutou compound fertilizer did not affected the soil health and ground water.If the price of Niutou compound fertilizer can be reduced,the economic benefits/unit area and the ecological benefit of planting sugarcane may increase significantly.
