Abstract
[Objective] The study aimed to explore the fertilizer technology for young plantation of Chinese fir and its benefit analysis. [Method] In the contrast test on the fertilizer application for 7-year-old young plantation of Chinese fir, 3 treatments of fertilizer application were set up as the calcium magnesium phosphate 500 g/plant, urea 250 g/plant and phosphate fertilizer 250 g/plant + urea 250 g/plant, with no fertilizer application as CK and they were applied to the young plantation through digging ring channel. The stock volume in each test plot were counted according to the investigation on the growth of tree height and the increment of tree chest diameter in the end (Nov.) of the year annually. [Result] As for the stock volume of the young plantation of Chinese fir after fertilizer application for 5 years, compared with the CK plot, the effect of phosphate fertilizer application was the best, with the stock volume increasing by 17.13 m3/hm2 on annual average and the net output value increasing by 33 776 yuan/hm2, that of the mixed application of phosphate and urea fertilizer was next, with the stock volume increasing by 9.04 m3/hm2 and net output value increasing by 16 284 yuan/hm2 on annual average, and that of urea fertilizer application was little, with the stock volume increasing only by 2.38 m3/hm2. [Conclusion] The phosphate fertilizer application got the best effect. After phosphate application, the forest growth of the young plantation of Chinese fir could be stable and its fertilizer effect was more obvious with time process of application.关键词
