Why did Magnolia fall down?

Why did Magnolia fall down? Is there any way to prevent it? Magnolia magnolia is an excellent urban street tree with white and large flowers, tall and straight trunk, beautiful crown, dark green leaves and strong anti-dirt and vacuuming ability. However, any good thing always has its shortcomings. Magnolia magnolia tree's poor lodging resistance is one of its weaknesses. It is found that there are three main reasons for Magnolia magnolia lodging. First, the head is heavy and the leaves are dense. Magnolia mandshurica leaves are leathery, large and thick, and the weight per unit area of large leaves in trees is more prominent. Magnolia magnolia has wide adaptability, like fertilizer and strong negative resistance, which promotes many branches and leaves and overlapping leaves, resulting in a large and heavy crown. Second, the shallow foot is light. In general, Magnolia magnolia was grafted with Magnolia mandshurica as rootstock, and it was found that the root system of Magnolia magnolia was underdeveloped, with few branches from the main root and few lateral roots that branched again, especially its root system was similar to the fleshy root and had poor propulsive ability in the soil. When it encountered consolidated soil, the root system could not extend, resulting in "shallow roots and light feet". The third is the strong wind. Due to the "head weight" caused by dense branches and leaves and the "light feet" caused by underdeveloped roots, some Magnolia trees in the street will lodge when attacked by strong winds. In this regard, the following measures can be taken. First, in the purchase of Magnolia magnolia tree, choose the seedlings with developed root system after many times of transplanting. Second, pruning and leaf pruning to solve the problem of "head weight", because Magnolia magnolia crown can be beautiful without pruning, and trees were not pruned in the past, so in order to solve the problem of "head weight", branches and leaves must be pruned before the rainy season and gale season comes. prune the branches and leaves to make them transparent and light to reduce resistance. Third, loosen the soil, fertilize, strengthen the root, strengthen the management, improve the consolidated soil around the tree, make the soil aerated and loose, and then apply an appropriate amount of phosphate fertilizer to strengthen the root, which is more conducive to the extension and development of the root system.
