摘要
本文总结了长白落叶松苗期不同密度的温、湿度变化状况.资料表明P600~P700能扩大苗冠高温区约1~3倍;生长季中(6~7月)苗冠部气温大于25℃时间能增加1~2h;14时能提高高温区气温0.5℃左右,有利苗木生长.
The temperature and humidity conditions of Larix olgensis seedling population under different densities were measured. The result showed that the high temperature space of the seedling canopy can increase 1-3 times under the density of 600-700 seedlings/m2. During growing season (June-July) ,the period when atmospheric temperature in the seedling canopy is greater than 25℃ can increase 1-2 hours under that density. And at 14 o'clock ,the temperature in the high temperature space can be enhanced about 0. 5℃,which is beneficial to the seedling growth.
