| 摘 要： | 通过田间试验 ,研究 p H值为 4 .86蔗作土每公顷施 15 0 0 kg石灰 (A处理 )、15 0 0 kg钙镁磷肥 (B处理 )和 180 0 kg石灰 + 90 0 kg钙镁磷肥 (C处理 )的效应。结果表明 ,3个处理均不同程度地提高了土壤 p H值 ;有效地促进甘蔗对 N、P、K,特别是 P的吸收 ;提高甘蔗单株绿叶数、伸长速、茎长、茎粗、单茎重、有效茎数及蔗糖分 ,改善甘蔗品质 ;每公顷蔗茎产量和含糖量分别提高 8.2 % -13.0 %和 10 .2 % - 2 2 .8%。 B、C处理的促进效应较 A处理明显

| Abstract: | Field experiment was conducted on sugarcane in acid soil (pH=4.86) applied with 1500 kg/hm 2 lime (treatment A), 1500 kg/hm 2 Ca Mg P (B) or 1800 kg/hm 2 lime + 900 kg/hm 2 Ca Mg P (C). The results were as follows. (1) The pH of each treatment was increased respectively. (2) Sugarcane plants uptook more N, P and K, especially P. (3) Green leaves, growth rate, stem length, stem diameter, stem weight, effective sucrose content of sugarcane were increased and juice quality was improved. (4) Cane yield was increased by 8.2%-13.0% and sucrose yield by 10.2%-22.8%. (5)Treatment B and C were superior to A. |
