Photosynthetic Characteristics of Seedling Leaves of Three Tree Species in Different Afforestation Time
摘要
Abstract
The Populus alba × Populus bolleana,Ulmus pumila,Xanthoceras sobifolia Bunge nutrition seedlings were planted in June,July and August growing season,the photosynthetic characteristics of three species were measured at rej uvenation period,so as to provide a basis for afforestation management at recovering stage. The results showed that photosynthetic characteristics of three tree species were significantly different;for the same tree species,net photosynthetic rate was not significantly different in different afforestation time,transpiration rate,stomatal conductance and intercellular CO2 concentration were different,the maximum value appeared at July.The variation of photosynthetic characteristics of three species was basically same in different afforestation time,net photosynthetic rate,transpiration rate,stomatal conductance and intercellular CO2 concentration continued to decline from 1 d to 3 d after transplanting,began to rise at 4 d after transplanting,restored to the level before planting from 5 d to 7 d after transplanting.The recovering stage of three different tree species was from 5 d to 7 d after transplanting,at this point the management of soil moisture should be strengthened and adequate water should be supplied to ensure the seedlings spend recovering stage as soon as possible,and increase the survival rate.关键词
