Question 2: Why do loquat trees wither and lack potassium in flowerpots? According to the appearance of plants, such as dwarfing, deformation, lateral branch growth, symptom color, shape, etc., it can be judged whether they lack some elements.
Symptoms can be divided into three categories:
1. Symptoms occur in the lower leaves (old leaves), not in the upper leaves: magnesium and potassium.
2. Symptoms are limited to the growing points of young leaves and tips of plants: calcium, iron, sulfur, boron, copper, manganese and zinc.
3. Symptoms appear in the upper and lower leaves, but the lower leaves are more serious: nitrogen and phosphorus.
(A) symptoms of nitrogen deficiency
The obvious symptoms of nitrogen deficiency are slow growth and yellow leaves.
(b) symptoms of phosphorus deficiency
The first symptom of phosphorus deficiency in plants is that the leaves are dark green or blue-green, and the maturity is delayed. Petiole, especially on both sides of vein, may produce anthocyanins with red or purple stripes, and gangrene spots will appear on petiole and leaf.
Symptoms of potassium deficiency
Potassium is a movable element in plants. Symptoms first appear mottled or yellow spots on the old leaves, and then appear necrosis at the leaf edge.
(d) symptoms of sulfur deficiency
Sulfur moves slowly in plants, and symptoms first appear in young leaves. Causing the leaves to turn yellow.
(5) Symptoms of calcium deficiency
Calcium transport in plants is very slow, so there is still a lot of calcium in old leaves when calcium deficiency has occurred in young parts. When calcium is deficient, the tip of the leaf bends, turns yellow and white, and the leaf edge folds up or down (parachute-like), sometimes secreting mucus. The veins of young leaves are yellow, and the veins are still green. In severe cases, the yellow and white young leaves gradually turn yellow, the leaf edge dies, and it is easy to wrinkle when calcium deficiency is extreme.
(VI) Symptoms of magnesium deficiency
When plants lack magnesium, the veins on both sides of the middle leaves begin to turn yellow due to chlorophyll degradation. Then it turns yellow and gradually forms an irregular shape, expanding. In severe cases, only green leaves remain at the bottom of the leaves, forming a V-shaped green figure.
(VII) Symptoms of iron deficiency
Symptoms of iron deficiency often appear at the top of new leaves. The edges and lateral veins of leaves are green, and the veins are light green to yellowish white.
(VIII) Symptoms of boron deficiency
Boron deficiency symptoms appear in growing tissues, such as apical growth points, young leaves, tubers, stems or fruits, and their symptoms vary from crop to crop.
(9) Symptoms of copper deficiency
The symptoms of copper deficiency first appear on the leaves of new shoots, which are dark green and curly, but the green branches below the leaf base often produce yellow spots due to the accumulation of carbohydrates.
(X) Symptoms of zinc deficiency
The symptoms of zinc deficiency first appeared in the leaves of new shoots, and the symptoms were slightly different according to crop types.
(1 1) Symptoms of manganese deficiency
The symptoms of manganese deficiency first appeared in the leaves of new shoots, and the veins between leaves were yellow and green, but only the parts adjacent to the midvein and the main vein remained green and showed dark green bands of different shades.
(12) Symptoms of molybdenum deficiency
Molybdenum deficiency will produce macula on young leaves of plants, which will curl inward and gradually turn brown. Another symptom is that the leaves become smaller and whip along the middle ribs. Yellowing and necrosis will occur between veins of old leaves.
(13) Symptoms of chlorine deficiency
The fluidity of plants is strong, and the lack of chlorine will inhibit the growth, leading to the withering and yellowing of leaf tips.
Question 3: If you really believe in Feng Shui, is it good for Feng Shui to grow loquat trees at home?
You need to know some basic knowledge of Feng Shui.
The orientation of the house must be determined by compass measurement.
(including the cemetery) accurate environmental pictures (of the main body of the house and the external environment).
Birth information of individuals and family members
Combined with the characters of the owner of the house, go to the site to inspect the traffic inside and outside the gas field.
Family members' housing transportation, housing surrounding conditions (external buildings, natural environment,), etc.
A lot of information needs on-the-spot investigation.
The situation is not consistent,
Like Chinese medicine, it varies from person to person, so it is possible to analyze and measure the accurate mountain direction.
Including the things used by the owner, everything in the space environment is definitely unknown.
Feng shui should never be based on feelings or one or two pieces of news.
Through very detailed field calculations,
The comprehensive judgment of geomantic omen is based on the combination of the internal structure and external layout of the house.
People who draw conclusions need to be very careful, otherwise they will be mistaken by others.
There are no good or bad feng shui houses and environments in the world. See who lives in them.
In the traditional sense, Feng Shui is neither good nor bad, but it is suitable for anyone.
I suggest you find a local geomantic wise man to make a decision on the spot.
In ancient times, there was a theory that one thing, one Tai Chi, including every grass and tree in nature, was related to the whole earth ecology.
It's best for people to find what suits them, but don't be superstitious.
Good luck.
In the attitude of respecting and inheriting a culture, we should learn as much knowledge as possible, and don't follow blindly.
Question 4: Can I grow loquat at at home? Pipa is a arboreal fruit tree. It grows very fast, and balcony cultivation seems inappropriate, but it is still young and can be controlled properly by pruning. In the first three years of seedling planting, in order to cultivate stronger branches, expand the crown as soon as possible and form it early, and lay a good foundation for early fruiting, the whole tree should be drained. Loquat trees should also prune some flower spikes in time to reduce the nutrient consumption of the trees and promote the huge fruit and good quality in the coming year. It should be done when all the flower heads of the tree are picked. First, the weaker flower heads on the fruiting mother branches of the crown are thinned, and then the multi-branch flower heads and the lateral spikes at the top and bottom of the flower heads of diseases and insect pests are cut off for a period of time, but 3-5 of them should be kept. When the dense and weak spike is cut off from the joint between the bearing branch and the spike, the whole spike can be cut off. Generally speaking, according to different tree potentials, the number of thinning ears accounts for 1/4- 1/3 of the total tree. Leave 3-4 buds on each side branch, and the rest are thinned out. It can reduce nutrient consumption and concentrate on flower and fruit development.
Question 5: How long does it take to water potted loquat? My family planted seeds in a pot when we ate loquat in 2002, and the seedlings grew the next year. This spring, when it grew to 40 cm high, we planted it in the ground, and now it has grown to nearly 1 meter.
Specific planting and ordinary plants, watering and fertilizing twice a month.
Loquat can grow naturally in the wild without special attention.
Question 6: How big pot should I use for potted loquat? Large pots are used for large flowers and small pots for small flowers, generally about 20 cm. However, pomegranate will grow bigger and belong to large pots and plants. You can use 50~60 flowerpots with the same length to a certain extent, or you can transplant them to open space for planting.
Question 7: The loquat tree suddenly withered. Why? When the rainy season comes, there should be no water in the loquat garden after the rain to prevent the roots of loquat from rotting and dying. Also, have you taken any medicine to see if you are sick? Because loquat is naturally strong, there will be no problems. The main common pests and diseases are red spider, yellow spider, tail worm, yellow caterpillar, longicorn beetle, loquat gray butterfly, pear moth, branch rot, leaf disease and so on. Leaf diseases should strengthen fertilizer and water management, improve irrigation and drainage facilities, and improve the disease resistance of trees. When it is hot and rainy in summer, spraying 30% Aimiao 3000 times solution +2% KaSu Ming 300 times solution on the leaves to control leaf spot and anthracnose, and using 2.5% force or 2000-3000 times solution to control pests. Make paste with 1:2 crown fungus copper and Lufeng 95, and smear the trunk 1 time every 4-5 days for 3 times continuously to prevent and control branch rot. April-May and August-165438+10 are the peak seasons for the occurrence of red spiders and yellow spiders. Use 1.8% easy-to-cut EC or 40% kulong 1500 times solution to control it!
Question 8: Why are the loquat leaves planted in the flowerpot dry? The basin is too small to control water, fertilizer and sunshine. If you don't come directly to the soil, you'd better plant it outside! !
Question 9: Can loquat trees be potted? Hehe, you can plant it in a pot. You don't want to eat its fruit anyway. But you can't leave it indoors for too long.
