1. Avoid using soil with bacteria or easy hardening.
No matter what flowers and plants are planted, the quality and variety of soil are related to the health of plant roots. Only by using suitable cultivation soil can plants thrive. For example, planting Magnolia grandiflora, using soil that is easy to harden or alkaline, can easily lead to root rot or poor growth, and plants are prone to a large number of fallen leaves and withering.
1. Mixed soil: When planting Magnolia, fertile, loose and well-drained slightly acidic soil or weakly alkaline soil should be selected, but in slightly acidic soil, Magnolia can grow more. When preparing soil, humus soil, river sand and garden soil can be mixed, and some base fertilizer can be added to make magnolia grow better.
2. Note: The cultivated soil recovered by itself shall not be directly used. There will be some invisible bacteria or eggs in the wild soil. If used directly, the roots and plants of Magnolia grandiflora may be invaded by bacteria or insects in the later maintenance, and the roots will rot or the plants will wither. Self-restoring and cultivated soil should be used after sterilization and egg killing. Can be exposed to the hot sun, high temperature and ultraviolet light can kill bacteria and eggs. Sun exposure 10 days can be used.
Second, avoid long-term maintenance in the shade.
Magnolia is a plant that likes sunshine. Although it can continue to grow in an environment with poor sunshine, if the sunshine is insufficient for a long time, it will grow white or breed bacteria, which will easily lead to root rot or a large number of leaves, and the plant will wither. In particular, long-term lack of light will also affect the photosynthesis of Magnolia grandiflora, and it will spend less or no flowers when it blooms.
1, location: attention should be paid to the cultivation of Magnolia grandiflora, and the best cultivation location should be selected according to the cultivation method. For magnolia planted on the ground, choose a place with better sunshine, so that magnolia can thrive. Potted magnolia, cultivated indoors, needs to be maintained in sunny places, not in dark places for a long time, which will not only affect the growth, but also make the leaves not green enough, the plants grow white and long, and will also affect the flowering.
2. Sunshine: If you want Magnolia to grow healthily and bloom as scheduled in the flowering period, you need to give enough sunshine. It takes about 6-8 hours of sunshine every day, which is beneficial to the photosynthesis of Magnolia, and the flower buds can change normally and bloom smoothly in the flowering period. However, potted Magnolia grandiflora can be properly shaded in summer when the sun is strong, and the environment is well ventilated.
Third, avoid root rot caused by excessive watering.
Magnolia grandiflora has a certain drought tolerance, and watering is often the primary cause of root rot and plant wilt. When Magnolia grandiflora is cultivated, if it is not watered, it will easily lead to root rot, a large number of fallen leaves, and the plant will gradually wither. Therefore, if you want to cultivate Magnolia plants well, you need to avoid excessive watering, and you need to water them according to their growth habits to make them grow healthily.
1. Watering: During the growth of Magnolia grandiflora, the water should be sufficient and the soil should be slightly moist. Usually, it is necessary to judge whether Magnolia grandiflora should be watered according to the wet and dry conditions of the soil. Only when the soil is completely dry or partially dry can it be irrigated by water. Pot soil can't have water, otherwise it will be wet for a long time, which will easily lead to root rot.
2. Note: The climate in each season is different, and it is rainy in spring, so the water content of cultivated Magnolia needs to be well controlled, and the accumulated water needs to be removed in time for ground planting. In summer, high temperature water evaporates quickly, so it is necessary to replenish water in time to prevent the leaves from turning yellow due to drought and water shortage. In autumn, when the weather turns cold, it is necessary to reduce the frequency of watering, and Magnolia grandiflora will grow slowly with the low temperature. After entering winter, watering needs more attention. If the soil is too dry, water it.
Fourth, avoid using concentrated fertilizer to produce chemical fertilizer.
No matter what kind of flowers and grasses are cultivated, fertilization must be carried out according to their growth conditions to maintain sufficient nutrients, so that the roots are developed and the plants are flourishing, so that they can flourish and bloom more and bigger flowers. The same is true of cultivated Magnolia grandiflora. If the nutrients are insufficient, it will also lead to slow growth or less flowering, but the fertilization is wrong. If the chemical fertilizer is applied too densely or untreated, it is easy to cause fertilizer damage and plant withering.
1. Fertilization: Magnolia grandiflora needs to be evenly fertilized and supplemented with various elements during the growth period, so that Magnolia grandiflora can flourish and flourish, and it needs to be applied about 1 time a month. Generally, it is necessary to apply fertilizer to Magnolia grandiflora in early spring and then in May-June, which can make it grow vigorously and promote flowering.
2. Note: To fertilize Magnolia grandiflora, it is necessary to control the amount of fertilization. Can not be a large number of fertilizers, nor can it be fertilized at one time, which is particularly easy to cause fertilizer damage. Magnolia grandiflora will burn its roots and leaves, and the plants will gradually wither. It should be applied thinly and diligently, and fully decomposed organic fertilizer should be applied. Moreover, it should be noted that the winter weather is cold, and Magnolia grandiflora leaves into dormancy, so it is not necessary to continue fertilization, otherwise it will easily cause fertilizer damage and unsafe winter.
If you want to cultivate Magnolia grandiflora, you need to learn to avoid the above four contents, and you need to do the following.
1. Pruning: In the process of cultivation, some branches and leaves of Magnolia grandiflora will inevitably dry up or be damaged by pests and diseases, so they need to be pruned in time to avoid nutrient loss, unhealthy branches and leaves, affecting healthy branches and leaves, causing healthy branches and leaves to suffer from pests and diseases, resulting in the whole plant withering. However, Magnolia grandiflora needs pruning when it is overgrown with weeds, when the plant posture is not beautiful enough, or when the flowers wither without leaving seeds, so as not to consume nutrients and affect the next flowering. After pruning, it should be noted that the wound on the branches of Magnolia grandiflora is not easy to heal, so don't water the wound to avoid bacterial infection and lead to rot and dryness.
Second, change pots: the root system of Magnolia grandiflora grows faster, and the deeper the root system is, the slower the growth space will be, or Magnolia grandiflora cultivated for a long time will not change pots for a long time. When the soil quality is not good, the ventilation and drainage will be poor, which will easily lead to rotten roots, so change the basin. Generally speaking, changing pots of Magnolia grandiflora needs to be decided according to its growth and soil quality. When the growth is slow, the root growth space is insufficient, or the soil ventilation and drainage are not smooth, the pots should be changed after flowering, and the fine roots or rotten roots should be trimmed at the same time. After sterilization and air drying, the pots should be placed with new soil.
abstract
Magnolia plants are difficult to maintain, mainly because they are not maintained according to their growth habits, which leads to the inability of Magnolia to grow under the required environmental conditions, and it is prone to root rot or plant wilting. If you want to cultivate Magnolia, you need to avoid the above four problems, maintain it according to the needs of Magnolia, use slightly acidic soil, maintain sufficient light, and properly water and fertilize it, so that Magnolia can grow healthily and vigorously. At the same time, it should also be noted that potted Magnolia grandiflora grows best at the temperature of 20 ~ 30℃, avoiding high temperature and high humidity, keeping the environment well ventilated and the plants growing healthily.
