| Abstract: | The experiment of fertilizer application was conducted in a 1-3-year-old larch plantation in Xiaojiu Forest Farm of Shangzhi County, Heiongjiang Province to promote the yield per unit area of forest. The application results of diammonium phosphate, superphosphate and urea fertilizers were significant different. The optimum application dosage was 50 g per tree. Application fertilizer in the second year and third year after planting could bring about good result. The best application method is to dig 10 cm holes in depth at a distance of 10 cm from the tree. The best time for application is at the beginning of June, and it is best to fertilize twice. |
