近来不少读来信指出:为什么有的人扦插育苗成活率很高,有的人扦插成活率低,甚至枯死?经了解并结合我个人的一点点实践体会,谈谈管理上容易被人们忽视的两个突出矛盾,即小气候湿度与介质湿度的矛盾和小气候温度与介质温度的矛盾。两个矛盾解决得如何,直接影响到扦插成活率。首先谈谈小气候湿度与介质湿度的矛盾。日照蒸发,容易使未生根的插条所含水分“收支”失去平 Recently, a lot of reading letters pointed out: why some people have a high survival rate of cuttage seedlings, and some people cut survival rate is low or even dead? After understanding and combined with my personal experience of a little practice, talk about management easily overlooked by people Two prominent contradictions, namely the microclimate humidity and the humidity of the conflict and the microclimate temperature and the temperature of the medium conflict. Two contradictions how to solve, a direct impact on the survival rate of cutting. First of all, talk about the contradiction between microclimate humidity and medium humidity. Sunshine evaporation, easy to cut the root does not contain the moisture contained in the “income” lost
