How to fertilize the magnolia?

The magnolia is a fat-loving flower, and the various mineral elements it needs mainly come from bonsai. The requirement of fertilizer quality of gentleman orchid is not high, and it is suitable to use the fertilizer made by retting sesame, soybean, river shrimp and so on. First boil the sesame seeds and soybeans to cool. Wash the prawns, then pour them into a container in a quantity of 1 to 3 each to ferment. After about a month, open the lid of the container and smell a sour smell, indicating that the fertilizer has been fermented and mature and can be used.

After treatment, the retting fertilizer can be divided into three states: the water fertilizer diluted with the ratio of water to fertilizer 4 is water fertilizer; the retted fertilizer is dried and ground into powder as dry fertilizer; the retted porridge paste is solid fertilizer.

For the topdressing of gentleman orchid, the key is to master the amount of fertilizer and the ratio of water to fertilizer.

The use of dry fertilizer

Sprinkle a certain amount of dry fertilizer into the topsoil of the flowerpot and pour water after evenly mixing to facilitate root absorption. For the amount of dry fertilizer, generally use half a tablespoon for seedlings, 2 tablespoons for middle orchid and 4 tablespoons for big orchid.

Use of water and fertilizer

Usually, water and fertilizer are applied a week after the seedlings are put into pot, especially when the leaves are unfolded, which can promote the development of the roots of the seedlings, enhance their ability of disease resistance and fungal resistance, make the leaves gradually thicken and bright, and the seedlings apply water and fertilizer. the ratio of fertilizer and water at 1:40 was better, and 1:20 was better for large and medium orchids. Generally early in the morning after the application of water and fertilizer, watering once, the amount of water should not be too large. This can not only promote the dissolution of fertilizer, but also rinse the newly grown fleshy roots to prevent damaging the new roots, and avoid breeding germs in summer. Thin fertilizer and water, can be applied once a week, should be careful not to apply thick fertilizer, thick fertilizer stimulation will make the new root rust, serious will make the new root atrophy.

The use of solid fertilizer

First dig out a small trench on the edge of the basin, sprinkle the solid fertilizer evenly, and then cover it with soil. The amount of fertilizer applied depends on the number and size of leaves. Seedlings are generally not suitable to use solid fertilizer, 50 grams of Chinese orchid at a time, 75-100 grams of Dalan at a time is appropriate. When applying fertilizer, be careful not to splash on the leaves. If you accidentally drop it, rinse it with clean water or wipe it off with a wet soft cloth. The times and quantity of fertilization should increase or decrease with the season. The growth of Magnolia is more exuberant in winter, it is necessary to apply fertilizer properly, the seedlings are once a week and once every 10 days, the concentration can be appropriately higher; in the growing season of spring and autumn, the concentration should be talked about. Summer season if

Take measures to make the temperature down, the humidity is enough, the sun is sufficient but not strong, you can continue to apply fertilizer, but the amount should be less than that in winter and spring; if the temperature is above 24 ℃, you should stop fertilizing or lose weight, and stop applying fertilizer in rainy season. It is better not to apply fertilizer in cloudy days, because photosynthesis cannot be carried out in cloudy days, and it is inconvenient to absorb after fertilization, and the roots will rot in fertilizer and water.
