福建红壤旱地多年来由于偏施氮肥,造成土壤中营养元素的不平衡,影响了甘蔗产量的提高和品质的改善。为了摸清红壤旱地甘蔗在生长发育过程中对不同营养元素的需求情况,于1983及1984年分别进行田间与盆栽试验。研究营养元素不同配比对甘蔗产量和品质的影响,并寻找最佳的养分配比,为今后科学施肥提供科学依据。 Fujian red soil dryland over the years due to partial nitrogen fertilizer, resulting in soil nutrient imbalance, affecting the sugar cane yield and quality improvement. In order to find out the demand of different nutrients during the growth and development of sugarcane in dryland of red soils, field experiments and pot experiments were conducted in 1983 and 1984 respectively. The effects of different nutrient ratios on the yield and quality of sugarcane were studied, and the best nutrient allocation was found to provide a scientific basis for future scientific fertilization.
