What s going on with the yellow leaves of the prickly plum raised in the greenhouse?

Maybe the water is not enough, and then there is not a period of flowering will appear this phenomenon, after my thorny plum blossoms bloomed, the leaves yellowed, the flowers withered, the thorns became soft, I thought it was going to die. But after a while, the new shoots and new leaves grow very quickly and vigorously, but they don't bloom. I'm wondering if it's intermittent, it's the case every time it's gone...

Try watering more.

Prickly plums are more hardy. It's too hot in the summer in the greenhouse. Remove the plastic from the top. The ventilation is also not smooth. Therefore, it is caused by dry heat and no wind, which can change the environment.

Greenhouse air conditioner to adjust out good benefits.

The main function of multi-functional greenhouse water temperature air conditioner is to heat up, cool, humidity and ventilation of various agricultural planting and breeding greenhouses, it has the comprehensive advantages of small size, large power, comprehensive functions, low cost, low operating costs, uniform temperature control effect, etc., which solves a number of problems in artificial temperature control technology in the production of agricultural greenhouses, and solves the shortcomings of high investment in traditional electric air conditioning and hot blast stove equipment, high energy consumption, poor effect, and only suitable for application in high-grade and high value-added greenhouse production.

Xinfuda greenhouse air conditioner is a necessary product for the cultivation of vegetable greenhouses, fruit tree greenhouses, breeding greenhouses, mushroom planting greenhouses, flower greenhouses and other facilities to achieve annual production. At the same time, it is also the first choice for plant heating and cooling equipment.

The yellowing of the leaves of prickly plum should be timely resistant to drainage, increase light, pay attention to ventilation and excessive fertilization.

Prickly plum belongs to the fleshy stems and leaves, not afraid of drought, afraid of waterlogging, if too much watering, it is easy to hurt the root system, resulting in yellowing and falling off the leaves, should be timely to the prickly plum drainage, be careful to loosen the soil, and strengthen ventilation, so that the water in the soil evaporates as soon as possible, at the same time, you can also move the prickly plum to a sunny place, bask in the sun, and it can recover after a while.

One of the reasons for the yellowing of Ye's cherry seeds is that too much fertilizer is applied or unfermented raw fertilizer is used, which will also cause the leaves to turn yellow, you can use water to water the roots of the thorn plum, let the water dilute the fertilizer in the soil, and then put the flowers in a cool place, wait for the potting soil to dry slightly, and then maintain it normally.

Daily maintenance of prickly plum

When cultivating thorny plum blossoms, sandy loam soil is the best choice, can be prepared with humus soil or peat soil plus sand and fertilizer, it is a light-loving plant, if the light is insufficient, it will lead to dull flower color, and even do not bloom, so when maintaining, it needs to be placed on the sunny windowsill, and maintain the ambient temperature in Shichang nuclear index eight to twenty-five degrees, and when the light intensity is large, shading measures should be taken.

In the process of growth, prickly plum is susceptible to rot disease, blight, aphids and other pests and diseases, so in the maintenance, it is necessary to regularly spray carbendazim, mancozeb, dimethoate and other agents to control pests and diseases, and when pruning the plant, it is necessary to take protective measures, because the branches and leaves of prickly plum are poisonous.

Solutions to yellowing of prickly plum leaves:

1. Reduce watering

Thorn plum belongs to the fleshy stems and leaves, afraid of waterlogging, too much watering will damage the root system, resulting in the leaves yellowing and falling off, at this time you need to stop watering immediately, and the pot pad is as clever as pure, discharge the excess water in the pot, pay attention to strict control of the amount of water when watering in the later stage.

2. Strengthen ventilation

If the indoor ventilation is poor, the plant will be in a sultry environment for a long time, which will cause the leaves to turn yellow, at this time, the window should be opened immediately for ventilation, or the prickly plum should be moved to the courtyard for maintenance.

3. Dilute fertilizer

Prickly plum does not like fertilizer, if you apply too much fertilizer or apply unfermented raw fertilizer during breeding, it will burn the root system, resulting in yellowing of the leaves, at this time you can irrigate the plant with water, dilute the fertilizer in the soil, and then put it in a ventilated place to dry the water.

4. Control drugs

When spraying prickly plum blossoms, pay attention to not spraying high-concentration agents directly, you need to dilute them with water into a solution first, and then spray them evenly, otherwise a large amount of residual oak will cause the leaves to wither and the flowers to wilt.

The growing environment of the prickly plum:

Warm, light-loving, drought-tolerant, damp-avoiding, cold-sensitive. It grows well in loose, well-drained sandy soils. Summer and autumn are the growing seasons, and the room temperature above 3 in winter can safely overwinter.

If it is above 15 years old and has full sunshine, it can still continue to bloom. If the room temperature can be kept above 15 in winter, it will bloom continuously throughout the winter.

If the humidity is too low, all the leaves will fall off and go into dormancy. The flowering period requires sufficient sunshine, and top dressing is applied once every half month, organic liquid fertilizer or compound chemical fertilizer. It is suitable for the growth of loose sandy soil.

It is widely cultivated in the tropical and temperate zones of the Old World; It is cultivated in both the north and south of China.

There are many reasons for the yellowing of the leaves of the prickly plum, and the first thing to find out the cause of the yellowing of the leaves of the prickly plum is to prescribe the right medicine:

1. Seasonal reasons:

1. It is normal for the leaves to turn yellow before the dormant period in winter, and new leaves will sprout on their own in spring. When entering the flowering period in winter, keep the potting soil moist, the temperature is higher than 15 degrees, and reduce watering. Excessive watering can also cause the leaves to turn yellow.

2. At the end of autumn, when the tiger thorn plum enters the full flowering period, it is also about to enter the winter dormant period, so it is normal for the leaves to turn yellow, even if the leaves fall off, new leaves will sprout again in spring.

3. In areas where the temperature is lower than 10 degrees in winter, the old leaves of P. satiflorum will fall off, leaving only the top young leaves; When the temperature is lower, all the leaves dry up and fall off. Because winter is the flowering period of Tiger Prickly Plum, in order to make the plant bloom more, it is necessary to keep the potting soil slightly moist, but this will also accelerate the yellowing and shedding of the leaves. During the flowering period, the amount of direct sunlight should be increased.

4. If you pay more attention to the preservation of the leaves of the plant, then it is recommended that you place the plant in a place where the indoor temperature is higher than 15 degrees in winter, water less, and let the potting soil be as dry as possible; Do not fertilize. In this way, the growth of the plant is slowed down and the leaves are relatively stable in a dormant state. It's just that if you do it quietly, it will affect the quality of flowering.

Two: growth factors.

In fact, the tiger thorn plum is very leathery, you can follow its natural growth law, in the autumn and winter, let it naturally yellow leaves, deciduous leaves, as much as possible to bloom. In the warmer spring next year, it will be even more leafy.

Three: Overwatering.

Artificially overwatered, if the temperature and light are suitable, flower friends can see if there is a lot of watering recently, resulting in stagnant water!

Summary. Causes of excessive water: Tiger thorn plum is more drought tolerant and does not usually need too much water.

If you water too much during normal maintenance, the plant will not be able to absorb as much water, and it will gradually form waterlogged. This affects the respiration of the roots and even causes the roots to rot, which makes the leaves yellow. Measures:

If the roots of the plant rot, it is necessary to depot it, remove part of the old soil, check the roots, cut off the rotten roots, and soak them in carbendazim solution to sterilize. After detoxification, remove and dry, and replant in dry soil.

Reasons for excessive water: Tiger thorn plum is more drought tolerant, which ear usually does not need too much water. If you water too much during normal maintenance, the plant will not be able to absorb so much water, and it will gradually form stagnant water.

This affects the respiration of the roots and even causes the roots to rot, which makes the leaves yellow. Procedure: If the root of the plant is rotten, it needs to be depotted first, and after removing part of the old soil, the roots should be checked, the rotten root system should be cut off and then soaked in carbendazim solution for disinfection.

After the poisoning is done, it is taken out to dry and replanted in the dry soil of Li Zuobu.

Reasons for poor ventilation: If the ventilation of the breeding environment is poor and the air does not circulate for a long time, it will not be conducive to the respiration of the plant, which will lead to yellowing of the leaves. Cuo shirt bend Yun Shi:

Adjust the ventilation conditions of the breeding environment, and open windows to strengthen air circulation. If this is not possible, it can be moved to a ventilated environment, such as a balcony or beam. If it's winter, you can ventilate it at noon when there is no wind.

The reason for the temperature is too low: Tiger thorn plum likes a warm environment, if the temperature is too low, it will frostbite and even freeze to death, making its leaves yellow and fall off. Measures:

To move it indoors to a warm place in time, the temperature is 15 degrees Celsius, which can allow the plant to grow normally.

The reason for the lack of light grinding oak: Tiger thorn plum prefers a sunny environment, and it needs sufficient light all year round to make it grow well. If there is not enough light, the leaves will turn yellow due to poor growth.

Measures: It needs to be transferred to a long-sunning, well-lit environment for maintenance, just pay attention to give it proper shade when the light is too strong in summer. It can be exposed to full sunlight in spring and autumn, and can be maintained in a well-lit indoor environment in winter.

1. The reason for the yellowing of the leaves of the prickly plum blossom. Watering problems: thorny plum less drought tolerance but not water tolerance, if the planting process is too frequent, it will lead to the soil is too wet and even there is water, it will cause the roots to be unable to carry out normal respiration, if it is easier to rot the roots in the water for a long time, can not absorb nutrients and cause the leaves to wither yellow, this reason is more common.

2. Improper fertilization: the growth process of thorny plum blossom does not need frequent fertilization, especially not key Meng can fertilize too much each time, you can fertilize an appropriate amount after May, but you need to choose fertilizer and dosage according to the size of the plant shape, if too much fertilization will lead to root injury, and too little fertilization may turn yellow because of lack of nutrients, so too much or too little is wrong.

3. Lack of light: prickly plum likes light but is not resistant to strong light, many times people will pot it indoors, if the light is more sufficient, it will not be a problem to grow, but if it is placed in the corner and room without light for a long time, it will not only cause problems such as yellowing of leaves, but also lead to steep growth or no flowering, and the color of the leaves will be dull and the ornamental value will be reduced.

4. Closed environment: Thorn plum is a plant that likes a humid environment, although its requirements for humidity are not so high, but at least to ensure that the usual environment is well ventilated, if it is always placed in a dense and impermeable place, not only the temperature is difficult to control within the appropriate range, but also because of the lack of air circulation, resulting in dry air, stuffy environment, and finally make its leaves yellow.

5. Pest and disease infection: although pests and diseases are not common, but its harm is very great, many pests and diseases will not only cause the leaves to turn yellow, but also make the leaves deformed, atrophy, the growth of the prickly plum will also be inhibited Zheng Jing, more serious will cause the death of the prickly plum shouted Liang Shen, found that pests and diseases are actually very simple, usually pay more attention to observe the leaf surface, if there are lesions, you need to spray in time.

There are several reasons why the leaves of the prickly plum are yellow and have fallen off:

1. Normal reaction during the dormant period.

Tiger prickly plum is neither resistant to high temperature nor cold, and there will be a short dormant period during the high temperature period in summer and the severe cold season in winter. After the tiger thorn plum enters dormancy, yellow leaves and partial defoliation are its normal reactions. At this time, as long as the yellow leaves are cleaned up, placed in a cool and ventilated place for maintenance in summer, and placed in a warm and sheltered place for maintenance in winter.

Don't be nervous, pay more attention to the growth state of the plant.

2. Poor ventilation

Tiger thorn plum likes a well-ventilated environment, if the ventilation is poor, the long-term indoor maintenance will not open the window will lead to uneven temperature and humidity adjustment, so the tiger thorn plum will yellow leaves and leaves, so pay attention to ventilation when maintaining.

3. The potting soil is damp

4. Overwatering

Tiger thorn plum is a fleshy leaf stem, so it can store water and be drought tolerant, so we need to pay attention when watering, not watering too diligently, and watering thoroughly every time. Overwatering can lead to stagnant water, which can damage the rhizomes and turn the leaves yellow and fall off for a long time.

5. There is a problem with fertilization

The flowering of tiger thorn plum is continuous, so it is a process of consuming nutrients, then we have to fertilize frequently, often talk about a small amount of fertilizer many times, the fertilization concentration can not be too low, the concentration is high and the roots are burned and the seedlings are burned, resulting in yellow leaves and leaves, the fertilization is too low, and the weak growth will also lead to leaf loss.
