Fertilization Experiment of Eucalyptus grandis×E.urophylla Clone GL-5
摘要
Abstract
A comparative experiment was conducted on the cultivation of high yield plantation of Eucalyptus grandis×E.urophylla clone GL-5 with six compound fertilizers so as to screen the compound fertilizers with better fertilization effects.A total of six treatments were applied to each compound fertilizer.Six kinds of com-pound fertilizers were applied to the reforestation of clone GL-5 plantation using the same effective amount of nutrients.Each fertilizer was divided into 1 base fertilizer and 3 top dressings.After the afforestation,the DBH and height increment of each experiment were measured regularly. The increment and economic benefits of each treatment were analyzed,and the effects of various fertilization treatments on afforestation were com-pared.The DBH,height and individual volume of 3.5-year-old was 12.66 cm,19.36 m and 0.118 1 m3with F3 treatment(base fertilizer was 4% nitrogen,10% phosphorus,6% kalium;top dressing compound fertil-izer was 15% nitrogen,8% phosphorus,7% kalium).F3 treatment had the highest growth increment in the six treatments with the highest economic benefit.Attention should be paid to content of N,K and P,and only a variety of suitable nutrient elements played the greatest role on fertilizer.关键词
