| 摘 要： | 【目的】研究有机碳肥对糖料蔗生长、产量形成及经济效益的影响，为有机碳肥在糖料甘蔗上的推广应用提供参考依据。【方法】采用随机区组设计进行田间小区试验，设4个不同肥料处理，分别为施用1800 kg/ha有机碳肥（处理A）、施用1800 kg/ha碳基有机—无机复混肥（处理B）、施用900 kg/ha有机碳肥+1800 kg/ha甘蔗复混肥（处理C）和施用1800 kg/ha甘蔗复混肥＋750 kg/ha尿素的对照处理（CK），分别调查各处理的甘蔗萌芽率、分蘖率、月生长速度、株高、茎径、单茎重、有效茎数、分蘖成茎率和锤度，并测定小区蔗茎产量，对比分析不同处理的经济效益。【结果】与CK相比，不同有机碳肥施肥处理对甘蔗萌芽率影响不显著（P>0.05），但处理B和处理C显著（P<0.05）或极显著（P<0.01，下同）提高了分蘖率和成茎率，也可不同程度地促进蔗茎生长。处理A、处理B和处理C的蔗茎产量分别较CK增产4.0%、14.9%和7.5%，蔗糖分也极显著高于CK，较CK增加0.77%~1.20%（绝对值）。经济效益分析结果显示，与CK相比，处理B的农业产值提高30.6%、工业产值提高23.2%，综合经济效益最佳。【结论】施用有机碳肥可改善甘蔗产量相关农艺性状的综合表现，提高糖料甘蔗的产量和蔗糖分，提高经济效益，以施用碳基有机—无机复混肥的效果最显著。建议在土壤有机碳缺失的广西蔗区推广应用有机碳肥。

| Abstract: | 【Objective】To study the effect of organic carbon fertilizer supply on growth, yield formation and their economic benefits of sugarcane, so as to provide a reference for the promotion and application of organic carbon fertilizer in sugarcane production.【Method】A field plot experiment was carried out in random block design, and the treatments of 4 different fertilizer application methods were designed:application of 1800 kg/ha organic carbon fertilizer(treatment A), application of 1800 kg/ha carb-based organic-inorganic compound fertilizer(treatment B), the application of 900 kg/ha organic carbon fertilizer in combination with 1800 kg/ha sugarcane compound fertilizer(treatment C) and 1800 kg/ha sugarcane compound fertilizer and 750 kg/ha urea(CK). The germination rate, tillering rate, monthly growth rate, plant height, stem diameter, single stem weight, number of millable canes, rate of tillering stem formation and Brix of sugarcane were respectively investigated in each treatment, and their cane yield was measured at the same time. Then the economic benefits of different treatments were calculated through multiple comparative analysis.【Result】Compared with the CK, different fertilization of organic carbon fertilizer treatments had no significant effect on the germination rate of sugarcane(P>0.05), but treatment B and treatment C had significant(P<0.05) or extremely significant(P<0.01, the same below) effects to increase tillering rate and the stalk formation rate, and they could also promote cane stem growth in different degrees. Therefore, compared with that of CK, the results showed that the cane yield of treatment A, treatment B and treatment C increased by 4.0%, 14.9% and 7.5%, respectively. Sucrose content was also significantly higher than CK, increasing by 0.77%-1.20%(absolute value). Economic benefit analysis showed that compared with CK, the agricultural output value and industrial output value of treatment B increased by 30.6% and 23.2%, and the comprehensive economic benefit was the best.【Conclusion】In conclusion, application of organic carbon fertilizer can not only improve the comprehensive performance of agronomic traits related to sugarcane yield, but also increase their yield and sugar content, as well as their economic benefit, then the effect of carb-based organic-inorganic compound fertilizer application is the most significant. Therefore, it is suggested to popularize the application of organic carbon fertilizer in Guangxi sugarcane planting areas with soil organic carbon deficiency. |
