Effects of Irrigation Intensity on Seedling Growth of Pinus sylvestris var.mongolica in Mu UsSandy Land
In order toinquire into the effects of different irrigation intensity on the dynamic growth and productivity of Pinus sylvestris var.mongolica plantation,the seedling height and ground diameter of Pinussylvestris var.mon-golica were simulated by field irrigation experiments.The results showed as the following two aspects.(1)Multi-ple comparisons between different irrigation treatments were carried out on five biologically significant indicators in the growth model,including theoretical growth upper limit,growth acceleration point,growth deceleration point,fast-growing point and fast-growing period.The difference of parameters dominated by irrigation intensity made the growth model of seedling height and ground diameter of Pinus sylvestris var.mongolica have polymorphism.(2)When the irrigation intensity was three times of the natural precipitation,the annual growth of seedling height was the largest.
