不同密度及施肥处理对香圆生长的影响

Effects of different density and fertilization treatments on the growth of Citrus wilsonii Tanaka

通过对设置在新余市新星园林苗木有限公司自有林地内不同密度和施肥量处理的标准样地香圆生长量的调查,来对香圆人工林生产过程中人工密度控制和施肥处理的有效性进行评价,并在方差分析的基础上进行多重比较,对比筛选适合生产的定植密度和施肥量。结果表明:密度控制和施肥均可有效促进香圆苗木生长,但并不是简单的越稀越好和越多越好,而是有一个临界值。对本研究而言,香圆园林苗木生产应以60株·667m-2的定植密度为最佳,再辅施1.0 kg的复合肥可有效促进生长和改善林相。

In this study,the growth of Citrus wilsonii in the standard plots of different densities and fertilization treatments set in Xinyu Xinxing Garden Seedlings Co.Ltd.'s own forest land was investigated to estimate the artificial density control and fertilization treatment during the production of C.wilsonii plantation.The effectiveness is evaluated,multiple comparisons are made on the basis of analysis of variance,and the planting density and fertilizer amount suitable for production are compared and screened.The results show that density control and fertilization can effectively promote the growth of C.wilsonii,but it is not simply that the thinner the better and the more the better,but there is a critical value.For this study,the planting density of 60 trees per 667m2 should be the best for the production of C.wilsonii,and the supplementary application of 1.0 kg compound fertilizer can effectively promote growth and improve the forest form.
