1、 Maintenance method of soil culture

1. Soil: if you want to grow more vigorously in soil culture, you should pay attention to the soil used. The soil should be soft, breathable, fertile and acidic. Only in this soil environment can the root system germinate better, absorb fertilizer and water, and grow vigorously. When mixing soil, an appropriate amount of rotten leaf soil and river sand can be mixed in the garden soil. Rotten leaf soil can improve acidity and softness, and river sand can improve drainage capacity. Note that the soil can only be used after disinfection. Or you can also buy special soil for flowers, which is also beneficial to its growth. If the soil viscosity and alkalinity are too heavy, it is easy for green pineapple to grow badly

2. Watering: lvluo likes humid environment, but it is afraid of waterlogging. If it is watered frequently or excessively during the curing period, the green pineapple can not be absorbed, and it is prone to rotten roots. The soil is too dry, which is not good for growth. It is recommended to water the surface soil after it is dry, preferably rainwater, well water and river water. Watering tap water for a long time will change the pH value of the soil and reduce the acidity. In this case, it is necessary to regularly water ferrous sulfate solution to improve the acidity of the soil. Lvluo also has higher requirements for air humidity. If the climate is dry, you can spray water frequently to improve the humidity

3. Temperature: lvluo likes warm environment, has slight high temperature resistance and is not resistant to cold. It needs good temperature control if it wants to grow vigorously. The temperature is best maintained between 15 and 28 ℃, and the lowest tolerable low temperature is about 5 ℃. Therefore, it must be moved indoors after winter. It is best to control the temperature above 10 ℃ to avoid frostbite. Note that if there is heating at home, don't put the green rose too close to the heating, otherwise it is easy to burn. In addition, when the high temperature exceeds 30 ℃ in summer, it is necessary to strengthen ventilation, water frequently and reduce the temperature appropriately

4. Light: green rose has strong shade tolerance and is afraid of strong light. If you want it to grow vigorously and its branches and leaves are greener, it's best to put it in a bright place and bask in the scattered light occasionally. For example, morning and evening light. It is not allowed to be placed in a cool environment for a long time, nor to be exposed to direct light for a long time, otherwise it will affect the growth

5. Fertilization: the demand for fertilizer is not large, but if you want it to grow more vigorously, you need to apply fertilizer appropriately in the peak growth season. Specifically, topdressing in spring and autumn. The compound fertilizer with more nitrogen elements is OK. After dilution, the fertilizer solution can be watered on the soil surface once every 20 days for two or three consecutive times. If the temperature in summer and winter is too high or too low, fertilizer should be stopped to avoid fertilizer damage

6. Soil change: the soil raised green pineapple should also change the soil regularly. It is best to change the soil once a year, and choose to change the soil once a year in spring or autumn. In this way, the soil has sufficient nutrients, is not easy to harden, and the growth space is more sufficient, which can promote the more vigorous growth of green pineapple. When changing soil, it is suggested to combine root pruning at the same time and trim away rotten roots, old roots and withered roots, so that it can better absorb fertilizer and water in the later stage and is conducive to growth

2、 Maintenance method of hydroponic culture

1. Water quality: pay attention to the water quality of green pineapple in hydroponic maintenance. It is best to use rainwater, well water and river water for maintenance. Such water quality is mostly acidic water, which is beneficial to its growth. If the tap water is used at home, it must be dried before it can be used, and the chlorine inside must be volatilized. Otherwise, the chlorine is too heavy, and it is easy to have yellow leaves after a long time

2. Water change: during water culture, the water needs to be changed regularly to ensure that the water quality is clean. Before rooting, it's best to change the water once a day. After rooting, you can reduce the change of water once, once every 10 to 15 days. If the water is found to be turbid or polluted, it shall be replaced in time. Add water in time when there is little water

3. Nutrient solution: the nutrient contained in the water is relatively small. If you want water to support the vigorous growth of green pineapple, you must add nutrient solution to ensure sufficient nutrients. The nutrient solution can be special for hydroponic culture, or a few drops of compound fertilizer can be put in the water to improve fertility. After changing the water every time, put it to give it sufficient nutrient supply

4. Root pruning: the growth rate of green pineapple is relatively fast, and the root system of water culture grows relatively fast. When it is found that there are old roots, dead roots, rotten roots or the root system is too long, it needs to be trimmed in time, so as to promote it to better absorb fertilizer and water and grow vigorously

5. Light: the water fed green pineapple can be properly exposed to the sun. It is best to see light for about 3 hours every day. Note that you must block the strong light at noon and bask in the sun sooner or later. In the environment of sufficient light, the leaves will better carry out photosynthesis, so as to accumulate more nutrients and promote faster growth and more vigorous growth

6. Temperature: Green pineapple likes warm environment, and the cold resistance of water culture is worse. The temperature is too low, and the water is easy to freeze, resulting in the death of green pineapple. It is recommended to control the temperature at about 15 ℃ and at least not lower than 10 ℃. It is usually moved indoors in late autumn. It has good temperature control in winter. In addition, pay attention to the high temperature in summer. It is best to move to the air-conditioned room in summer. If the temperature is too high, the water temperature will also rise, which is unfavorable to the growth of green pineapple
