Abstract
[Objective]Study the effect of fall fertilization to Pinus tabulaeformis container seedlings growth,nitrogen uptake and cold tolerance. [ Method ] We make fall fertilization to Pinus tabulaeformis container seedlings , which have been processed in exponential fertilization level of 10, 40,80,and 120 mg/plants in the growing season ,set four treatment levels of 0 (control) ,12,24 and 48 mg/plants,seedlings will besed to do afforestation experiment after a growing season in the greenhouse cultivation in the following year. [Result] While fall fertilization of 24 mg/plants is the best treatment,under the treatment of 40E -24,N content was increased 15.9% compared to the control,cold resistance at -20 t has increased 95.2% ,afforestation effects are the best. [Conclusion]Fall fertilization can improve the nutrient content,cold tolerance and afforestation effects the following year. On the contrary,excessive fall fertilization (48 mg/plants)does not promote seedling growth but inhibit or damage. 关键词
