【摘要】 研究采用田间随机区组试验,通过对撑绿竹不同施肥时期处理的立竹数、胸径和秆材产量进行比较,寻求撑绿竹最佳的施肥时期。结果表明,在施肥总量相同的条件下,1年施用3次(3、8、12月)的处理对产量的提高效应最好,其次是1年施用2次(3、8月),二者均具有较高的经济效益。1年施用1次(3月、8月或12月)对产量的效应较低,经济效益较低。1年施用1次的时候,在12月和3月施用效果较好。在生产实际中,考虑到劳力和费用问题,可以采用在3月和8月追肥2次。更多还原

【Abstract】 In order to determine the best fertilization times,compared the culm numbers per clump,diameter at breast height(DBH)and yields of Bambusa pervariabilis×Dendrocalamopsis daii with different fertilization times through a randomized block field trials in study.The results showed that the yield of application fertilizer for 3times a year was the highest,followed by application fertilizer for 2times a year,both with higher economic efficiency.The yield of application fertilizer for 1times a year was the lowest,with lower economic efficiency.Application fertilizer in December and March was better than in August when application fertilizer 1times a year.Taking into account the labor and costs,application fertilizer for 2times a year in March and August can be appled in actual production.更多还原
