How to raise the latest green apple?

How to raise green pineapple? Green pineapple is a large evergreen vine of Araceae. It grows in tropical areas and often climbs on the rocks and trunks of rainforest. It has strong entanglement, developed air root and can be cultivated in water. The following editor will introduce how to raise green pineapple.

How do green pineapple reproduce?

Green pineapple is usually propagated by cutting method. In late spring and early summer, strong green rattan is selected, branches of 15 cm to 30 cm are cut, leaves of 1 to 2 nodes at the base are removed, care not to hurt air root, then insert into plain sand or cinder, depth is 1x3 of cuttings, drenched with enough water in shaded place, spray water on leaves every day or cover with plastic film to moisturize, as long as the environment is not less than 20 ℃, the survival rate is more than 90%. The specific methods of cutting are as follows:

1. Selection and treatment of cuttings: cuttings should choose semi-lignified branches with strong growth and no diseases and insect pests, cut into 10-13 cm long, cut into oblique notches at the bottom, leave 2-3 leaves at the upper end, and cut off half of the leaves to reduce water evaporation and facilitate the survival of cuttings.

2. Cutting substrate: the cutting substrate requires loam or sandy soil with high humus content, which is loose and breathable, well drained, and preferably vermiculite, which can take root quickly and have a high survival rate. Disinfect the soil with 2% formalin or 5% potassium permanganate before insertion.

3. Cutting method: the lower end of the prepared cuttings was quickly dipped in ABT rooting powder or indolebutyric acid, then inserted into the prepared substrate, put into the soil, poured water, so that the cuttings were in close contact with the substrate, and then covered with plastic film.

4. Plug-in management

Pay attention to keeping the soil moist and high air temperature after ① insertion. The soil moisture is about 50%, while the air humidity is 80% and 90%.

At the initial stage of ② cutting, the shade degree of the shade shed is kept at about 80%, which can not only prevent strong direct sunlight, but also ensure sufficient scattered light, so as to facilitate photosynthesis and rooting of leafy cuttings.

Through the above treatment, ③ basically takes root after 20 days, and the film can be removed to increase the light. at the same time, attention should be paid to foliar spray and shade on sunny days in summer, cold prevention in winter, and normal management in the basin about 10 days after rooting.

How to raise green pineapple?

1. Lighting

The original growth condition of ① green apple is in the forest sheltered by towering trees, and the positive direction is not strong. However, in the north of autumn and winter, in order to supplement the deficiency of temperature and photosynthesis, its illuminance should be increased. You can put the green pineapple in the best indoor light, or move to a sealed balcony to bask in the sun at noon. At the same time, open windows as little as possible when the temperature is low, because the leaves may be frostbitten in a very short period of time.

② indoor cultivation can be placed next to the window, but to avoid direct sunlight. Too strong sunlight will burn the leaves of green pineapple, overshade will make the beautiful markings on the leaf surface disappear, usually to receive four hours of scattered light, green pineapple growth and development is the best. Therefore, the green apple can be placed in the sunny place indoors all the year round. In darker rooms, it should be moved to a strong light environment every semimonthly to restore for a period of time, otherwise it is easy to make the internodes grow and the leaves become smaller.

③ greens can be placed near the east or north windowsill in spring, summer and autumn, and south-facing windows in winter. If it is placed in an environment where the light is too dark for a long time, it will not only cause the trailing stem to grow, the Internode becomes longer and the plant shape sparse, but also the yellow and white stripes on the leaf surface will become smaller and pale, and even the spots will disappear and fade to green completely. Such as outdoor training, should pay attention to sunshade, especially in summer should pay more attention to prevent direct light, otherwise it will lead to new leaves smaller, leaf color dim, while easy to burn leaf edge.

2. Temperature: in the north, when the room temperature is above 10 ℃, the green pineapple can survive the winter safely, and when the room temperature is above 20 ℃, the green pineapple can grow normally. In general, it is not a big problem for families to reach this temperature, we should pay attention to avoid excessive temperature difference, and at the same time, we should also pay attention to the leaves not close to the heating equipment.

3. Humidity: humidity refers to the water content of the air in the plant growing environment. Under the condition of ensuring normal temperature, increasing humidity is very beneficial to the growth of plants. The following methods can be used to increase the temperature. Keep the plant close to the humidifier, which opens for more than 5 hours a day, and the plant can enjoy the water mist emitted by the humidifier; spray water on the leaves, stems and air roots of the plant with a sprayer adjusted to the fog scale, several times a day; keep the right amount of water in the flowerpot tray and increase the local temperature of the plant through its evaporation Gently wipe the leaves with cold wet towels or toilet paper or apply them lightly for a short time (1-2 hours a day); cover the plants with a transparent plastic film to create the effect of a small greenhouse and replenish plant moisture by evaporating moisture in the soil for less than 2 hours a day. Too long time will affect plant ventilation and photosynthesis.

4. Water: the amount of water in autumn and winter should be strictly controlled according to room temperature. Before heating, the temperature is low and the soil evaporation of the plant is slow. In order to reduce watering, the amount of water should be controlled between the original 1pm 4-1max 2. Even after heating, watering should not be too frequent, watering should be less watered into the basin, and should be oozed by brown silk. In addition, water should be sprayed to the aerial root growth of the brown column to reduce the insufficient water absorption of the root caused by rapid evaporation. Winter water to dry after a day of water is better, the water is too cold easy to damage the roots. When raising water, the amount of water should not be too much, just submerge the roots, and it is easy to rot the stems and leaves when there is too much water.

5. Soil: in winter, it can grow well under the bright scattered light indoors, with strong stem nodes and gorgeous leaf color. During the growth period, there is a higher demand for water, in addition to normally replenishing water to the basin soil, but also often spraying water to the foliar surface, and rattan cultivation should also spray more water on the brown hair column to make the brown hair fully absorb water for the aerial root absorption around the stem. Nitrogen, phosphorus and potassium compound fertilizer can be applied every 2 weeks or 0.2% potassium dihydrogen phosphate solution can be sprayed every week to make the leaves green and the markings more bright. Green pineapple likes to be moist, it is appropriate to keep the basin soil moist regularly during the growing season, and avoid drying the basin soil, otherwise it is easy to cause yellow leaves and poor plant shape. If too much watering causes stagnant water in the basin soil, it is easy to cause rotten roots and withered leaves, especially when the room temperature is low in winter. While fully watering in summer, we should also pay attention to often spraying water on the leaf surface. If the climate is dry in winter, the leaves should be sprayed with warm water every 4-5 days to wash the dust off the leaves to keep the leaves bright and green.

6. Fertilization: in autumn and winter in the north, plants grow slowly or even stop growing, so fertilization should be reduced. Before winter, liquid inorganic fertilizer is mainly poured and sprayed, and the time is about 15 days. After winter, fertilizer is mainly sprayed on the leaf surface, mainly sprayed through the stomata on the leaf surface, and the fertilizer is absorbed through the stomata on the leaf surface, and the fertilizer effect can act directly on the leaf surface. Foliar fertilizer should use special fertilizer, ordinary inorganic fertilizer is not easy to be absorbed by foliar. Peking University Huasheng series and Japanese flowers can be used as foliar fertilizer.

7. Plastic surgery: 4-5 plants are planted or cut directly in each pot, and brown columns are set up in the middle of the pot to facilitate the winding and upward growth of green pineapple. Plastic pruning is carried out in the spring. When the stem vine crawls all over the brown column and the tip exceeds the brown column 20cm or so, cut off the stem tip 40cm of 2-3 plants. When new buds and new leaves sprout after truncation, cut off the stem tips of other plants. If the whole plant or the lower half of the plant is defoliated due to freezing in winter or other reasons, the half of the stem can be cut short by 1 / 2, and the other half by 2 / 3 or 3 / 4, so that the cut mouth is staggered so that the new leaves growing meters under the cut can be quickly covered with brown columns.
