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。
Using sugar cane variety Xintaandu 22 as test material, field experiments were conducted to investigate the effects of different compound fertilizers on sugar cane yield and quality. The results showed that the application of the first brand compound fertilizer sugarcane emergence, good growth, high sucrose content, per kilogram of nutrients than the compound fertilizer and Fengling compound fertilizer 82.9 and 113.8 kg, respectively, an increase of 50.46% and 85.31%. The application of Ngau Tau brand compound fertilizer also played a certain role in preventing soil acidification and improving soil environment in sugarcane field. It can be seen that the output of the same sugarcane needs to be input into less than the amount of compound fertilizer, and its pollution to the soil and water environment is lower. If the price of the compound fertilizer is reduced, the economic and ecological benefits per unit area will be even more remarkable.
