摘要
[目的]探讨含腐殖酸水溶性肥料结合水肥一体化技术在甜梨上最佳施用量,完善灌云县甜梨施肥指标体系。[方法]设置水溶性肥料用量(0、225.0、337.5、450.0、562.5 kg/hm2),研究不同用量水溶性肥料对甜梨品质、产量及收益的影响。[结果]在结合水肥一体化技术条件下,水溶性肥料用量为450.0 kg/hm^2时,甜梨的产量(22 950 kg/hm^2)、增产率(51.8%)及产投比(24.1)均达最高,且高于同等用量(450.0 kg/hm^2)的人工点肥。[结论]结合水肥一体化技术,水溶性肥料在甜梨上的最佳施用量为450.0 kg/hm^2。
[Objective]To study the optimal dosage of water-soluble fertilizer with humic acid combined with water and fertilizer on sweet pear,and improve fertilization index system for sweet pear in Guanyun County.[Method]Under other conditions,the amount of water-soluble fertilizers was 0,225.0,337.5,450.0,562.5 kg/hm 2,and effects of different water soluble fertilizers on the quality,yield and income of sweet pear were studied.[Result]Under the condition of water and fertilizer integration technology,the yield of sweet pear(22 950 kg/hm 2),increase rate(51.8%)and input-output ratio(24.1)reached the highest value,and the highest yield was higher than that of the same amount(450.0 kg/hm 2)of artificial fertilizer.[Conclusion]Combined with water and fertilizer integration technology,the best application amount of water-soluble fertilizer on sweet pear was 450.0 kg/hm 2.
