Morphology and growth habits of qianqianmu

Form of money tree

The flower stalk and inflorescence of the money tree are less than 20 cm long, thin, light green and inconspicuous. The flowering period is about 20 days and has no special ornamental value. But home, Feng Shui, it is the best choice for many people. In recent years, the price of money tree is very high. The price of each tree is as high as hundreds of yuan, and the market is quite good

Growth habit of money tree

Money tree likes warm, hot, slightly dry, semi cloudy and the environment with small annual temperature change. It is relatively drought resistant, but it is afraid of cold, strong light exposure, heavy soil viscosity and ponding in the basin soil. If the permeability in the basin soil is poor, it is easy to cause its tubers to rot. The soil is required to be loose and fertile, well drained, rich in organic matter and acidic to slightly acidic. It has strong germination power. After cutting off the thick pinnate compound leaves, the top of its tuber can quickly produce new leaves

Key points of cultivation and management of money tree

Temperature

The suitable temperature for its growth is 20 ℃ to 32 ℃. Whether potted or ground planting, it is required to have small annual temperature change. Productive cultivation is best carried out in a greenhouse with controllable temperature. Every summer, in the Yangtze River Basin, when the temperature is above 35 ℃, the plant growth is poor. Measures such as covering black net for shading and spraying water to the surrounding environment should be taken to cool down, so as to create a suitable living environment with appropriate space temperature and relatively dry. It is best to maintain the greenhouse temperature above 10 ℃ in winter. If the room temperature is lower than 5 ℃, it is easy to cause the plant to suffer cold damage and seriously endanger its survival. In the winter of 2002, the outdoor temperature in Hefei suddenly fell below - 7 ℃. When the indoor temperature is lower than 3 ℃, many gold trees planted in homes or offices were frozen to death. In late autumn and early winter, when the temperature drops below 8 ℃, it should be moved to a room with sufficient light in time. During the whole overwintering period, the temperature should be kept between 8 ℃ and 10 ℃, which is safe and reliable

Illumination

A tree with a certain degree of shade should have a strong shade, but it should be resistant to sunlight. It should avoid direct sunlight. In particular, it should avoid exposure to the sun after long rain and early sunshine in late spring and early summer and baking in 5 to 6 hours before and after noon in summer. Otherwise, it is very easy to burn the young leaves. For productive cultivation, from late spring to mid autumn, it should be placed in a shade with 50% to 70% shading, but it should not be too dark, otherwise it will lead to slender new tender leaves and sparse leaflet spacing, which will affect the compactness and beauty of the plant. Supplementary light should be given to the potted plants moved to the shed in winter. For balcony cultivation, it should be moved indoors in a few hours before and after noon in summer. In winter, the potted plants should be placed in front of the window with sufficient light, and should not be stuffed in an excessively dark corner, otherwise it will lead to yellow and absent-minded leaves. In the south, it is placed indoors in a bright space, away from direct sunlight, and the water in the basin soil remains dry. After applying the mixture of 0.1% potassium dihydrogen phosphate and 0.2% urea once a month, the plant can remain disease-free for many years. The newly extracted pinnate compound leaves do not show obvious phototaxis and still maintain a good plant shape. Therefore, it is suitable for long-term indoor display

Moisture

In order to maintain the potted money tree, efforts should be made to provide it with a humid and dry environment. For maintenance on the balcony at home, if it is above the third floor, you can put the potted plants on the wet sand table. Usually, pay attention to spraying some water on the leaf surface to wash the fine dust attached to the leaf, and pay attention to shading at the same time. For indoor curing, when the room temperature is above 33 ℃, spray water on the plants once a day to keep the basin soil slightly wet. For productive cultivation, for plants placed under the shade, due to the inherent strong drought tolerance of the plant, it is also better to keep the basin soil slightly wet and dry. However, the occasional irrigation of excessive water and fertilizer will not cause the root system to rot due to drowning. In winter, pay attention to spraying water on the leaf surface and the surrounding environment, so that the relative air humidity can reach more than 50%. After the Mid Autumn Festival, we should reduce watering, or spray water instead of watering, so as to facilitate the safe winter of new tender leaves. In addition, in winter, special attention should be paid to that the basin soil should not be too wet, and it is better to be dry. Otherwise, under low temperature conditions, the basin soil too wet is more likely to lead to the decay of plant roots and even the death of the whole plant

Soil

Due to the special climatic conditions in the origin of golden tree, it has formed strong drought resistance. Therefore, the basic requirement for the cultivation substrate is good permeability. The cultivation substrate is mostly mixed with peat, coarse sand or washed cinder and a small amount of garden soil, and its pH value is adjusted to between 6 and 6.5, in a slightly acidic state. Due to its huge tubers, developed roots and long pinnate compound leaves, it is advisable to plant in a deep blue and white porcelain basin or purple sand basin, but the lower part should be padded with more stones, bricks or bark blocks, with a height of about 1 / 4 of the depth of the flowerpot, so as to create a good root environment for air permeability and water filtration. In the growing season, loosen the soil once a month to keep the cultivation substrate transparent. Check frequently in rainy season. If there is ponding in the basin, turn over the basin and change the soil in time

Fertilizer

Money tree likes fertilizer. In addition to adding an appropriate amount of retted cake fertilizer or multi-element slow-release compound fertilizer into the cultivation matrix, thin cake fertilizer water can be poured once a month in the growing season, or 0.2% urea plus 0.1% potassium dihydrogen phosphate mixture can be used. For potted money trees in the north of Huanghuai River, an appropriate amount of ferrous sulfate can also be added to the irrigation and fertilization solution to prevent physiological yellowing of leaves. After the Mid Autumn Festival, in order to make it survive the winter safely, nitrogen fertilizer should be stopped and 0.3% potassium dihydrogen phosphate solution should be applied twice to three times continuously to promote the hardening and enrichment of its young leaf axis and newly extracted leaves. When the temperature drops below 15 ℃, all forms of topdressing should be stopped to avoid fertilizer damage and root injury under low temperature conditions
