Culture methods and matters needing attention of pineapple how to fertilize pineapple

Has anyone ever raised a red landscape plant at home? yes, the editor is talking about pineapple, do you know how to raise pineapple? Is it true that some people use the wrong method to cause the death of pineapple? In order to reduce the mistakes made by everyone in cultivating pineapple, the editor will introduce the matters needing attention in detail.

Culture methods and matters needing attention of pineapple

I. Culture methods of pineapple flowers

1, lighting: pineapple habits like semi-overcast, should prevent the hot sun exposure, put half-shaded place or bright window, indoor. The original state of the pineapple is parasitic under a tree in the tropical rain forest, so it does not have a great demand for sunlight. When the sun is exposed to too much time, it will produce some leaves yellowing, and then, the flower tip is a little dry, and so on. If cultivated outdoors in spring, summer and autumn, it should be properly shaded, especially 70% shading in summer. Direct sunlight will make the leaf temperature higher than the air temperature. If the leaf temperature is too high, there will be burns and scorched leaves, which will fade the bud and slow the leaf growth.

2. Temperature: the optimum growth temperature of cultivated pineapple is 20 ℃ to 30 ℃, the highest temperature should not exceed 35 ℃, and the lowest temperature is 14 ℃. Freezing injury may occur at any time when it is lower than 10 ℃. It is best not to put it under the heater in winter, because in that case, it will be particularly dry and will be roasted, just like a person cannot always stand next to the heater and get hot easily.

3. Moisture: the basin soil of the pineapple family should be slightly dry on the surface of the basin soil, that is, the surface of the soil should be 1-2cm dry, and then irrigated for the second time, it should not be too wet, and it is easy to soak the roots too wet. All plants of the pineapple family have a leaf tube at the root of the leaf, and the leaf tube has a sink. It is necessary to ensure that there is often water in the tank, which cannot be cut off. After a period of time, for example, about ten days, the water in the leaf tube should be replaced to avoid smelly water. Usually, you can also spray some foggy water on the surface, leaves, and flowers. The optimum air relative humidity is 70% to 80%, and should not be less than 50%, because keeping the high air humidity in the cultivation environment is the key to the successful cultivation of Anthurium andraeanum. Therefore, foliar spraying should be carried out all the year round.

4. Use soil: potted red palm should choose the matrix with good drainage, and the mixed substrate of peat, perlite and sand for large-scale production, the ratio is: 1 cubic meter of peat: 4 to 5 kilograms of perlite: 0.15 cubic meter of sand. Its PH value remains between 5.5 and 6.5. If you can put a small amount of rotten chicken manure, cake powder or bone meal and other base fertilizer in the bottom of the basin, it will grow better.

5. Fertilization: during the growing season from April to September every year, liquid fertilizer should be applied every two weeks, fermented organic fertilizer can be applied, 0.1% urea and 0.2% potassium dihydrogen phosphate solution can be sprayed on the front and back of the leaves, and some extremely thin liquid fertilizer can be injected into the leaf tube, which is absorbed by the scales at the base, and the ratio of nitrogen, phosphorus and potassium is 10: 15: 20.

II. Points for attention of pineapple flowers

1. Late spring to autumn is the growing period of pineapple flowers, which can appropriately increase the amount of water, and some clear water can also be irrigated in the leaf tube. You should change the water once a month to prevent the water from deteriorating and smelly.

2, often spray foliar water, dry some on the basin in winter, but not too much.

3. From May to September, nitrogen fertilizer should be applied once a week, and phosphorus and potassium fertilizer should be applied appropriately before flowering to promote the flower to be colorful.

4. when flowering, do not irrigate in the tube, store it in a place away from the sun, which can prolong the flowering period.

5. When entering the dormant period after anthesis, the pedicel must be cut off to reduce the consumption of nutrients.

6. Don't fill the tube with water in winter.

How to fertilize pineapple

1. The fertilization of pineapple can be determined according to the growth trend, generally apply fertilizer once a week or 2 weeks, and try fertilizer once a month or not when the temperature is low in winter.

2. One month before the pineapple bloom, you can't apply fertilizer, otherwise it will affect the pineapple blossom.

3. Pineapple is very sensitive to copper and chlorine, which can easily lead to blackening of leaves, so try to avoid it.

4. Spring is the peak season for the growth of pineapple, so we should pay attention to fertilizing the pineapple.

How to transplant pineapple seedlings

1. Observe the growth of pineapple cubs. When they grow to 1/3 to half the size of the parent plant, they can be safely separated from the parent plant.

2. Cut off the cub from the place attached to the mother plant with a clean serrated knife. The seedlings may or may not have their own roots. Either way, because rootless pineapple cubs are easy to grow new roots.

3. Put the pineapple seedling in a 7.6cm jar filled with a loose and well-drained medium, such as pine needle mixture. Don't cover the lowest leaves with soil.

4. Poke three or four straight branches in the soil around the pineapple cub to support it until it grows strong roots intact.

5. Feed a certain amount of fertilizer to the mother plant. When you remove the seedling, don't throw it out even if it no longer looks beautiful. Seedlings usually induce pineapples to produce more viable offspring until they die.

6. Put the transplanted pineapple plants in a warm room with bright indirect light. When it takes root, don't expose it to strong sunlight.

7. Water the seedlings enough to keep them moist evenly, but not moist. Don't let it dry completely. If you are growing in a variety of cups, fill the cups with water. Spray the seedlings every day.

How long can the pineapple live?

Generally speaking, they die after flowering. After the pineapple blossoms, the central leaf clump dies and the collateral seeds continue to grow. The roots can be removed from the mother plant and replanted. By doing so, we can pass it on from generation to generation. If you want more breeding points, you can change the pot in spring, cut off the small tuber cuttings from the tubers of the mother plant, or use the root buds sprouted from the roots of the old plants to avoid shade, moisturize and keep warm.

People who raise pineapple should note that pineapple is different from other plants. It has a hibernating period in winter. It does not need to water and fertilize it during that period of time. After that time, it will be watered and fertilized, and although it can be put indoors, it is easy to attract insects in summer and needs special treatment.
