How to water magnolia (how often) how to fertilize magnolia

The new poems are old, and the barren pavilions in the south of the Yangtze River are cloudy every autumn. Affectionate does not change the color year after year, thousands of years of heart to give to you. This poem is the best description of magnolia. Magnolia represents nobility and holiness, and the conservation of magnolia is also very knowledgeable. If magnolia is to grow well, efforts should be made on watering management and lighting.

How to water magnolia flowers (how often)

1. Watering at the right time

Magnolia magnolia is a fleshy root, which needs water and is afraid of stagnant water.

Therefore, from early summer to late autumn, water should be watered once a day to keep the soil moist, but in hot "dog days", water should be watered once in the morning and evening, and water should be sprayed on the leaves and flowerpots to increase air humidity.

Using tap water to water magnolia flowers, we should pay attention to prevent soil alkalinization, such as yellow leaves should be applied ferrous sulfate or 0.7% to 0.8% acid vinegar water to water roots.

Leaves can also be sprayed with 0.3% to 0.4% acid and vinegar, and the effect is also very good. Do not accumulate water in the flowerpot in the rainy spring season, otherwise the roots will rot.

2. The light should be suitable.

Magnolia is a positive flower, which needs plenty of sunlight and should be maintained on the balcony or sunny ground during the growth period, especially during flowering. The light should not be less than 6 hours a day.

If the Magnolia magnolia is preserved in a shaded place, it will only grow leaves but not blossom, or blossom very little, slender branches, light leaves, thin leaves, no luster, which is very disadvantageous to its growth. But in the hot and hot "dog days" to moderate shade, generally 12:00 to 16:00 every day to avoid scorching sun exposure, but also to avoid brick walls or cement floor high-temperature radiation.

At this time, it is not only necessary to spray water to the plant to cool down, but also to water or spray water to the ground to cool and dissipate heat, increase air humidity and artificially create a suitable environment.

How to fertilize Magnolia

Magnolia should replenish nutrients, which is an important part of flowering management. Magnolia is a fat-loving flower because it has a long flowering period and blossoms more. To this end, timely and regular replenishment of nutrients, in order to blossom, large flowers, colorful flowers, flower fragrance.

In addition to applying sufficient base fertilizer in the pot, organic liquid fertilizer dominated by phosphorus and potassium should be applied every 5 to 7 days from May to October, such as rotten cake fertilizer and water. The principle of fertilization is to apply thin fertilizer frequently, and you can also take the method of lightening it first and then thickening it. Do not apply raw fertilizer, otherwise it will burn roots. At the same time, extra-root fertilization was carried out every 7 to 10 days, and leaves were sprayed with 0.5% plant oxytocin and 0.3% potassium dihydrogen phosphate.

Main Diseases and Control methods of Magnolia

Methods for prevention and control of anthrax: strengthen water and fertilizer management, enhance tree potential, improve disease resistance; remove diseased leaves in time, remove fallen leaves and burn them at the end of autumn; if there is a disease, use 75% chlorothalonil wettable granule 800 times liquid or 70% anthrax Fumei 500 times solution for spray, once every 10 days, continuous spraying 3 to 4 times can effectively control the disease.

Prevention and treatment of chlorosis: chlorosis is a physiological disease, mainly caused by excessive stickiness of soil, excessive pH value and insufficient supply of iron. 0.2% ferrous sulfate solution can be used to irrigate roots, or 0.1% ferrous sulfate solution can be used for leaf spraying, and more farm manure should be applied.

Leaf burn prevention and control methods: increase watering times to keep the soil moist; apply more organic fertilizer to enhance tree potential and improve plant resistance; whitening or entangling trees.

Planting methods of Magnolia

Magnolia, Magnolia and other magnolia species are commonly used in sowing, grafting, cutting, tissue culture and so on.

1. When sowing, we must master the mature period of the seed. When the seed turns red and blossoms, it will be picked immediately. Early harvest will not germinate, and late harvest will easily fall off. The fruits with red outer seed coat were soaked in cold water and scrubbed except for clean seed coat. The seeds were dried and stored in layer sand. The seeds were sown from February to March the following year. The height of one-year-old seedlings was about 30 cm. Those who cultivate large seedlings are transplanted in the next spring, properly cut off the main root, re-apply base fertilizer, and control the density, the qualified seedlings with complete crown, rare buds and plant height of more than 3 meters can be cultivated in 3 to 5 years. After 2-3 years of planting, it can enter the full flowering stage. This kind of seedling has strong growth potential and strong adaptability, and its effect is not inferior to that of grafted seedlings.

two。 Grafting, usually rootstocks are Magnolia, Magnolia and other magnolia plants, the methods are cutting, splitting, abdominal grafting, bud grafting, etc., high survival rate and rapid growth. The survival rate of grafting in late autumn is more secure than that in early spring.

3. Cuttage, which is the main propagation method of Magnolia. The cutting time has a great influence on the survival rate, which is generally carried out from May to June, and the survival rate of young trees is the highest in the same year. Soaking the base with 50ppm naphthylacetic acid for 6 hours could increase the rooting rate.

4. Striping is a traditional breeding method, which is suitable for the preservation and development of famous and high-quality varieties. Purple magnolia is the most suitable to use this method, select well-growing plants, take 1 ~ 2-year-old branches with a diameter of 0.5 cm ~ 1 cm as strips, if there are branches, can be pressed on the branches. The time of striping is 2 ~ 3 months. After pressing, it took root in the same year, and the longer it was connected with the mother plant, the more developed the root system was and the higher the survival rate was. It can blossom in 2-3 years after planting.

5. In recent years, using the method of tissue culture and using the buds of Magnolia as explants, tissue culture has been successfully cultured in test tube. This method is of special significance in the preservation and development of new types bred by budding and hybridization.

Cuitiao is strong enough to draw the wind and light the fragrance of honeysuckle, jade and snow. The rhyme friend knows that the person is good, the curtain gently unlocks the white neon clothes. The beauty of magnolia is difficult to describe in words. When witnessing the moment of life in full bloom, I feel that the world seems to be a new life. Magnolia brings spring and beauty to us. May you seize the bloom of every spring.
