Cultivation techniques in Jin Yulan;
1, water and fertilizer management
Magnolia grandiflora is neither waterlogging tolerant nor drought tolerant, so the principle of "liking wet and fearing waterlogging" should be strictly followed in cultivation and maintenance. In the process of cultivation and maintenance, many people think that Magnolia grandiflora is afraid of waterlogging and should be watered as little as possible. This understanding and practice is very wrong, because Magnolia grandiflora is afraid of waterlogging, which does not mean that it likes drought. It likes humid environment itself, so it is necessary to master the degree that the soil should not be too dry or too wet in water management.
2. Overwintering management
Although Magnolia grandiflora can tolerate the low temperature of -20℃, overwintering management should be strengthened for small Magnolia grandiflora and Magnolia grandiflora planted in that year. In addition to watering the pit with freezing water in the middle and late months of 1 1 10, the pit should be covered with grass, plastic film or ridged with soil, and the tree can be painted white to prevent defoliation in spring. Magnolia grandiflora planted for many years can only be treated with antifreeze and painting.
