What about the green and yellow leaves of hydroponic culture

Some people say that green pineapple is easy to raise and live when it comes to water, but what you don't know is that newly bought green turnips, whether hydroponic or soil, need a certain period of adaptation, otherwise it is easy to yellowing leaves! Now for everyone to analyze the hydroponic green radish leaves yellowing how to do?

Green pineapple leaves yellowing management measures are very simple, first of all to find the cause of yellowing, green pineapple can transport cuttings to breed, each of its roots have a leaf bud, as long as a section of planting can grow. When the green apple leaves turn yellow, remove the rotten roots and just change the water. Just transplanting can not be directed by strong light, can be placed in a place with weak light, the newly planted green apple will take root in about 20 days.

First, the cause of yellowing

1. Environmental mutation

Generally, the newly bought green apple has an adaptation period of about 1 month to the new environment, and the bottom yellow leaves are normal, but remember: yellow or dead leaves should not be peeled off directly and should be cut off from the middle of the petiole so as to avoid direct peeling causing too much water loss and increasing the wound; as a result, the upper leaves will still be yellow.

2. Discomfort of light and temperature

Green pineapple likes to grow in the shade. Exposure or strong light will wither the tips and edges of flowers and plants, and macula will emerge in the leaves. On the contrary, when the leaves are kept in dim condition for a long time, the leaves can not cooperate with each other and cause the leaves to turn yellow. It is best to put it in proper lighting conditions, such as incandescent lamps. Green turnip likes high temperature, humid, semi-overcast environment, can not bear cold, overwintering temperature is not lower than 10 ℃. It is sensitive to temperature, avoid direct sunlight in summer, and it is easy for leaves to turn yellow and fall off under strong light. It can grow well under the bright scattered light indoors in winter, and has a higher requirement for water during the growth period.

3. The water quality is poor

Hydroponic green pineapple may also be due to bacteria in the water, if it is tap water culture, it may be due to the high content of bleach in the water. Green pineapple itself is not resistant to low temperature, low temperature for a long time and large water will lead to rotten roots, resulting in insufficient water supply to the roots, and finally the root leaves begin to turn yellow, and the top leaves lose their luster.

II. Solutions

1. Plenty of sunshine

It should be placed where the scattered light is sufficient, and water is often sprayed to the leaf surface during the growth period. Spraying 0.2% potassium dihydrogen phosphate can restore the stripes on the leaf surface. Use a large culture container as much as possible, and oxygen can be added to the water if possible.

2. Change water frequently

For hydroponic green apple, water is a very important part, you can use tap water, well water, clean river water, etc., but the water should be kept for a day or two before it can be used. Then there is the change of water once a week in hydroponics. If you have the conditions to put some Maifan stone or small stone, it will effectively reduce the occurrence of yellow leaves. Rinse the roots well when changing water, and cut off the diseased roots. Don't put too much water, just don't have a root. When raising water, it is recommended to wrap the roots, soil and sawdust of green pineapple with cloth and put them in water.

3. Rational fertilization

Spraying 1% urea is also OK, any creature has a life cycle, it may be old and let nature take its course, only when it is withered and yellow, it will send new leaves, there is no need to worry.

The editor reminds you to remove the yellow leaves in time when the green pineapple leaves turn yellow. don't feel such a pity! Do not wait for the beginning of hydroponics, but also have rotten roots, but also in time to clean up! Improve ventilation, improve water quality, can properly add nutrient solution, drop every Wednesday! Add it when you change the water (once a week if you add the nutrient solution).

Of course, the newly bought green apple has an adaptation period of about one month to the new environment. The yellow leaves at the bottom are normal. The yellow leaves should not be peeled off directly, but should be cut from the middle of the petiole to avoid water loss and increase the wound, resulting in the upper leaves still yellow. If the leaves are yellow, you should pay attention to control the amount of water and put the green apple in a well-ventilated place with scattered light!
