1、 Soil curing method

1. Soil: pay attention to the soil used for the green pineapple cultivated in soil. It is best to be soft, breathable, fertile and slightly acidic. In such a soil environment, the green pineapple will grow more vigorously and absorb fertilizer and water better. The soil can be mixed with garden soil, rotten leaf soil and river sand, or you can buy special soil for flowers by yourself

2. Watering: lvluo likes humid environment and has poor drought tolerance. During the maintenance period, water frequently to make the soil moist, especially in the peak growth season. The best water for irrigation is rainwater, river water and well water. Such water quality is acidic and conducive to growth. If you use tap water for a long time, you need to water vinegar or ferrous sulfate regularly to improve the acidity of the soil and avoid being too alkaline. It needs to be watered well to avoid water accumulation. If the climate is dry, you need to spray water often

3. Temperature: lvluo likes warm environment, poor cold resistance and slight high temperature resistance. Usually it is best to provide it with a temperature between 20 and 28 degrees. The temperature is low after winter, so temperature control measures should be taken in time. Those placed outdoors for maintenance should be moved indoors as soon as possible, and the indoor temperature should be controlled at about 10 degrees to avoid frostbite. When the high temperature exceeds 30 degrees in summer, it is necessary to strengthen ventilation and spray water frequently to cool down

4. Light: Green pineapple is shade resistant and not sun resistant. During the curing period, you don't need to be exposed to the sun often, but you can't put it in the shade for a long time. It's easy to have yellow leaves. It is suggested that it should be exposed to more light in the morning and evening, and can be exposed to light for about three hours every day, which can promote its normal photosynthesis and make its leaves greener. Note that the strong light at noon must be blocked and not exposed to the sun, otherwise the leaves will be burned

5. Fertilization: Green pineapple has certain barren resistance, but its growth speed is fast in spring and autumn, and it will consume more nutrients. It is suggested to apply fertilizer appropriately to supplement nutrients. The fertilizer with more nitrogen elements can be selected. It is recommended to dilute it with clean water and then irrigate the fertilizer solution, so as to absorb quickly and avoid fertilizer damage

6. Changing pots: the growth rate of green pineapple is relatively fast. Under normal circumstances, it should be changed once a year. The time is selected in the spring and autumn growing season. When changing the basin, the basin soil should be prepared in advance. The new basin should be slightly larger than the old basin to meet its demand for space. The soil is soft, breathable, fertile and acidic. After removing the pot, it is necessary to properly prune the roots, cut off the dead roots, rotten roots and old roots. Reasonable pruning can promote better absorption of fertilizer and water in the later stage, and disinfect and sterilize after pruning. After handling it, plant the green pineapple again. After entering the soil, pour water in time and maintain it in a warm, ventilated and cool place, which will soon return to normal growth

2、 Hydroponic curing method

1. Water quality: attention should be paid to the water quality for hydroponic maintenance of green pineapple. It is best to use clean river water and well water. If tap water is used, it must be dried before it can be used. The chlorine in tap water is too heavy, which will hinder the growth over time

2. Change water: at the initial stage of water culture, the water should be changed frequently. It is best to change it once a day before rooting, which can promote faster rooting. After rooting, we should reduce the number of water changes, and add water in time when there is little water. Under normal circumstances, change the water every 10 to 15 days. It is found that the water quality becomes turbid and needs to be replaced in time

3. Nutrient solution: the nutrients in the water are limited. Aquatic plants generally need to add nutrient solution dropwise. Sufficient nutrients can promote its vigorous growth. Just use the special nutrient solution for hydroponics, and add two or three drops each time. Or you can put granular fertilizer into the water and use ordinary urea particles

4. Root pruning: the root system of water fed green pineapple grows fast. It is recommended to prune regularly. The rotten roots, withered roots and old roots shall be cut off in time, and the excessively long roots shall be cut short, which can promote it to better absorb fertilizer and water, so as to grow vigorously

What about green pineapple and yellow leaves

1. Suitable light: the yellow leaves of green pineapple may be caused by poor light. Long periods of exposure to light or direct sunlight can lead to yellow leaves. If there is a lack of light, move to a place with soft light as soon as possible, and bask in the scattered light, which can promote the recovery as soon as possible. If it is sunburned by direct light, remove the yellow leaves as soon as possible, move to a cool and well ventilated environment, and spray water appropriately to make it recover as soon as possible

2. Reasonable temperature control: lvluo likes warm environment and poor cold resistance. Whether it is soil or water, it is very sensitive to low temperature environment. If the temperature is below 10 ℃ for a long time, it is easy to be frostbitten, resulting in yellow leaves. In this case, the temperature must be increased. It is best to control the temperature above 10 degrees. If the temperature is appropriate, it will recover slowly

3. Water quality problem: if the water is not changed for a long time, the water quality is turbid, resulting in its root system can not breathe normally, and it is easy to yellow leaves after a long time. In this case, it is necessary to change the water as soon as possible to ensure that the water quality is clean

4. Soil problems: the yellow leaves of green pineapple raised in soil are likely to be soil discomfort. The soil used is alkaline or too viscous. In this case, it will hinder root respiration, so it is easy to have yellow leaves. It is suggested to replace the soil as soon as possible to ensure that the soil is acidic, soft and breathable

Propagation method of green pineapple

Green pineapple is usually propagated by cutting. At the end of summer, the climate is suitable for rooting. Cut the strong branches, 15 to 30 cm in each section, remove the bottom leaves and retain the air roots. Use pure sand as the matrix. Insert the cuttings directly into the matrix, about one-third of the depth of the cuttings. After planting, the surrounding soil shall be compacted and watered in time. In the later stage, provide a warm environment and spray water frequently, so that it will soon take root and survive, and the survival rate is more than 90%
