1976-1980年,我们研究了不同剂量的无机肥料对桧柏生长的影响。试验小区设在中亚林业科学研究所库宁试验站。海拔高度为1700-2500米。供试土壤为褐色碳酸盐土。土壤机械和农化分析资料表明,按其机械组成,属于粘重土,0-25厘米土层内的腐殖含量不超过3.94%。应当指出,土壤内的全氮和全磷含量很丰富,然而,有效态含量却不足。这说明有必要增加土壤肥力,施 1976-1980, we studied the effects of different doses of inorganic fertilizers on the growth of juniper cypress. The experimental plot is located at Kuning Experimental Station of Central Asia Forestry Science Research Institute. The altitude is 1700-2500 meters. The test soil is brown carbonate soil. Soil mechanics and agrochemical analysis data show that, according to its mechanical composition, belonging to clay soil, 0-25 cm soil humus content does not exceed 3.94%. It should be noted that the soil is rich in total nitrogen and total phosphorus, however, the effective content is not enough. This shows the need to increase soil fertility, Shi
