Growth habit of Yushu
Yushu is native to southern Africa. It has a certain impact on the original growth environment. Yushu likes a warm, dry and sunny environment. Not cold-resistant, afraid of strong light, slightly resistant to shade. Sandy loam with fertile soil and good drainage is better. The temperature is not lower than 7℃ in winter.
Cultivation methods of Yushu:
1. Pot soil requirements: The most suitable time for changing pot soil and planting is early spring. Potted soil should be loose, fertile and well drained. Pot soil can be 2 parts humus soil or peat soil, 2 parts garden soil, 3 parts coarse sand, 1 part limestone gravel, or 3 parts humus soil, garden soil, coarse sand, 1 part mixed culture soil with bone powder and plant ash.
2. Temperature requirement: The temperature between 20-30 degrees is most favorable for the growth of Yushu. Spring and autumn are the best seasons for Yushu to grow.
Yushu is afraid of strong light. When the temperature is high in summer, we should pay attention to keeping plants in the shade to avoid direct sunlight. When the temperature of Yushu's growing environment is higher than 38 degrees, the growth rate will start to slow down and even enter a short dormant period. Pay attention to the temperature in winter and put the plants in a greenhouse, preferably in a sunny place. The room temperature should not be lower than 7 degrees. Below zero, plants will freeze to death. Yushu, which is in the growing period, needs shade in addition to high temperature and heat in summer. All should be placed in sunny places. 3. Watering requirements: When Yushu is in the growth period, the watering times should be controlled at 1 time, once every two to three days. There should be no stagnant water, and the soil in the basin should be avoided from being too wet. In summer, the watering times should be controlled, and ventilation should be strengthened to avoid defoliation in Yushu. To cultivate Yushu in winter, water should be reduced. The specific principle depends on the dry and wet conditions of the soil in the basin.
It is best to dry the basin soil a little. 4. Fertilization requirements: Yushu can be properly fertilized during the growth period. Generally, the liquid fertilizer of decomposed pancakes is applied 2-3 times a month. Sufficient base fertilizer should be applied before soil replacement or planting, and decomposed organic fertilizers such as chicken manure, pigeon manure, bone meal, manure and various cake fertilizers can be added to the cultivated soil as base fertilizer. In order to keep the plant plump, the fertilizer and water should not be too large to avoid excessive growth.
Matters needing attention and common problems in Yushu culture
1. Is Yushu poisonous?
A: The branches and leaves of Yushu contain a lot of Euphorbia fischeriana. When people touch the juice in the branches and leaves, it will cause redness, swelling, pain and blistering of the skin. If you accidentally splash it in your eyes, it will lead to blindness. In fact, don't let children eat juice by mistake, don't eat branches and leaves, just pay attention.
2. How long does Yushu last?
If the temperature and other conditions are suitable, it will take 2-3 years to blossom. Generally, potted Yushu will bloom for more than 10 years. Flowering period 12 to March of the following year, 5 petals, the color is
3. Matters needing attention in cultivating Yushu
(1) First of all, Yushu grows rapidly. Change pots every spring, add rich soil and keep them in sunny places for maintenance.
(2) Apply thin fat water every 10 day and a half, and water every 2 ~ 3 days to achieve both wet and dry purposes. When the summer is hot, the swallows' palms are in a semi-dormant state, for fear that strong light will burn the leaves. At this time, it is necessary to do a good job of shading maintenance. summer
(3) stop fertilizing in the current season,
Pay attention to ventilation to prevent the leaves from turning yellow and falling off. If it rains heavily, avoid heavy rain and showers to avoid root death. (4) From August to June, it turned cold in the autumn of 5438+00, and the swallows' claws began to grow again. It is necessary to strengthen the lighting again and remove the shading equipment. Fertilization and watering at this time are the same as in spring.
(5) Before the first frost enters the greenhouse, put it indoors in the sunny place, stop fertilizing and water less.
Basically, water is poured once every half month, and the amount of water is half that of summer. (6) Swallow palm is not cold-resistant in winter, and the temperature should be kept above 7℃. Prune once a year, change pots in spring or enter the greenhouse in late autumn to keep the plant shape elegant all year round.
