摘 要:研究了叶片喷施氮肥对油松生长及电导率、丙二醛含量的影响规律,以期为生产中确定适宜的喷施浓度提供理论依据。试验结果表明:所有喷肥处理株高均高于对照,其中1.60%处理处于最高值,9月份比对照提高了39.75%,差异显著;9月地径0.80%和1.60%处理分别比对照提高32.41%、52.78%,两个处理均显著高于对照;电导率和丙二醛含量1.60%处理最低,显著低于对照。综合分析认为,油松育苗中尿素喷施浓度以1.60%为宜。The test studied on the influence of foliar applications of nitrogen fertilizer on the growth of Pinus tabuliformis Carriere and conductivity, MDA content in order to provide a theoretical basis for determine the appropriate production spra ying concentration. The results showed that: all spraying fertilizer treatment plant height were higher than the control and 1.60% treatment highest and then higher than control 39. 750/00 in September and have significant differences; the diameter 0.80 % and 1.60 % was higher than control 32. 41% , 52.78 % and have significant differences with control in September; con ductivity and MDA content 1.60% treatment lowest and significantly lower than the control. Comprehensive analysis that Pinus tabuliforrnis Carriere spraying urea concentration of 1.60% is appropriate.
