| 摘 要： | 分析2011～2012年合浦县甘蔗新台糖22号3个“3414”肥料效应试验，结果表明，施肥处理均能显著提高甘蔗的产量和经济效益，产量比不施肥处理1(CK)增长17.0%～64.1%；经济效益增收0.30万～1.43万元/hm2。建立3个试验的肥料效应函数模型，综合得出甘蔗新台糖22号最高产量10.70 t/hm2、最高施肥量氮(N)530.0 kg/hm2、磷(P2O5)116.0 kg/hm2、钾(K2O)340.7 kg/hm2和最佳经济产量10.6 t/hm2、最佳施肥量氮(N)438.6 kg/hm2、磷(P2O5)110.9 kg/hm2、钾(K2O)272.9 kg/hm2。结合当地实际情况，总结出合浦县中低等肥力田块种植甘蔗新台糖22号的科学施肥配方为氮(N)450 kg/hm2、磷(P2O5)120 kg/hm2、钾(K2O)280 kg/hm2，施肥比例为N∶P2O5∶K2O＝1∶0.27∶0.62，产量10.59～10.70 t/hm2。

| Abstract: | Introduced the basic composition, component design, working principle and main technical parameters of small cane ridge breaking fertilizing machine. The machine with walking tractor which can complete the walking tractor, ratoon cane ridge breaking, fertilizing disposable. Measured by the performance index, the results show that the machine in ridge depth of 150-200 mm; Fertilizer containing weight 50 kg/time, fat smoothly, fertilizing soil rate is above 85 %; 0.12- 0.14 hm2/h productivity, fuel consumption of 6.6 L/hm2, the machine is a kind of simple and compact structure, assignment of good quality, high efficiency, low cost of small sugar cane machine which has good application prospects. |
