Abstract
The effects of slow-released fertilizer on morphological indexes , yield and economic benefit of yam tubers were studied using Japanese yam as test material .With the treatment without fertilizer as con-trol, two treatments were set as slow -released fertilizer and fast -released fertilizer with the same nutrient content .The results showed that there were significant differences between fast -released fertilizer and slow -released fertilizer in morphological indexes and yield of yam tubers .The slow -released fertilizer treatment could significantly increase the tuber length , tuber diameter , rate of marketable tuber and yield;the effect was the best when using 200 kg of slow -released fertilizer per 666.7m2; the yield increased by 44.95% and 25.80%compared with the control and fast -release fertilizer;the net income was 16 604.81yuan per 666.7m2 , which was 87 .82%higher than that of control and 57 .39%higher than that of fast -released fertilizer .关键词
