Growth habit of agarwood
Liquidambar formosana is a positive tree, but it is also slightly tolerant to shade and likes warmth. It requires deep soil layer, vigorous germination, slow growth and long life, but its seedlings are not cold-resistant and need protection in North China. Plants can withstand the low temperature of-10℃, and they like the soil with sufficient sunshine and no water accumulation. Can be used for garden shrubs and pruning. Wild in the dry-hot valley area with an altitude of 1 300 ~ 2 300 m in north-central Yunnan and southern Sichuan.
Liquidambar formosana mainly grows in dry-hot valleys, valley sparse forests, hillsides, hillside shrubs, limestone mountain forests, limestone hillsides and sparse forests, with a lower elevation limit of 150 and an upper elevation limit of 2700. Born in limestone forests or bushes at an altitude of 580-2700 meters.
1. Water and soil: Don't water agarwood too often. It is advisable to water every 3-5 days. Every watering must be permeable, that is, the water must wet the bottom. Too much watering will rot the roots. The soil must have good water permeability. Just give the soil when you buy it.
2. Transplant problem: Because the original flowerpot was ugly, I just bought it and transplanted it. Here comes the problem. After transplantation, agarwood will shed its leaves, which is a normal reaction. Don't worry too much.
3, temperature: as long as it is placed indoors, winter is no problem. Because the indoor temperature of more than ten degrees in winter is still good.
4, sunshine: wood likes sunshine, you can bask in the sun every day, but don't be exposed for a long time. Generally put it on the balcony or in a sunny place indoors. Fragrant wood is also slightly shade-resistant, and it's okay not to bask in it for a few days.
5. It is not recommended to keep plants near the computer for a long time when they are weak. Radiation and computer cooling are still very bad.
6, the wind blows: agarwood can not stand the strong wind, and the leaves will fall off when the wind is strong. Because the leaf connection point of fragrant wood is very fragile.
Family potted method of agarwood
The tender leaves of Aquilaria sinensis are red, bright, delicate in color, slow in growth, easy to shape, and have a faint fragrance, which can purify the air and drive away mosquitoes and flies. People like to use it for indoor potted plants. Choosing ideal plant materials is the basis of potted plants. Family potted plants are mainly small and large, creating a natural and fresh feeling of moving wild landscape trees into the home. Therefore, it is necessary to choose carefully, choose agarwood seedlings with bent trunk and old tree pockets with old posture and beautiful and simple tree shape to cultivate pots. The wild tree bags excavated in Shan Ye are better, but the author does not advocate it, because it will cause ecological damage. After the plants to be cultivated are selected, preliminary pruning is carried out according to the idea, and pruning methods such as thinning and short cutting are flexibly used to remove cross branches, overlapping branches, pest branches and overgrown branches. Choose a purple sand pot with good air permeability as a potted container, cover the pot with soil and compact it, and water it to keep it moist. Because agarwood likes sunshine, it should be cultivated in ventilated and light-transmitting places such as window sills and balconies. In the daily management and protection, we should flexibly use plastic techniques such as coiling, bundling and twisting to shape according to the situation. After several years of management and protection, ideal potted plants can be cultivated.
Disease prevention and sowing of agarwood
Defoliation control
Fragrant wood leaves are usually lost due to improper watering. Watering should adhere to the principle of doing nothing, just watering thoroughly, don't get wet for a long time, and don't accumulate water on the tray for a long time! ! Don't water, just water the skin, be sure to water it thoroughly! Generally speaking, if the water is poured for more than 10 seconds to several minutes, the water will be discharged from the bottom due to the difference of basin size and soil type. Lighting is also uncomfortable. It is easy to appear when there is a long-term lack of light conditions. Poor ventilation can also cause the leaves of fragrant wood to fall off. Good ventilation conditions should be maintained.
control of insect
If there are scale insects on the branches and leaves or red spiders on the leaves, special insecticides can be sprayed to control scale insects, such as fenthion, chlorpyrifos, dicofol and nisolone to control red spiders.
Sowing technique
After years of experiments, Yunnan Linming Landscaping Co., Ltd. has come to the conclusion that fresh seeds must be sown, and once the seeds lose moisture, they will lose their germination ability. Mature and full seeds have gray-blue epidermis, red is empty, and there is no kernel, so they will not germinate. The seeds began to ripen in late June. After the mature seeds are harvested, the red float is removed, and the germination rate is over 90% after peeling. After 10 days at room temperature, the germination rate will be greatly reduced.
Causes of old leaves falling off in agarwood cultivation
1, improper watering: mu is generally defoliated due to improper watering. Watering should adhere to the principle of doing nothing, just watering thoroughly, don't get wet for a long time, and don't accumulate water on the tray for a long time! ! Don't water, just water the skin, be sure to water it thoroughly! Generally speaking, if the water is poured for more than 10 seconds to several minutes, the water will be discharged from the bottom due to the difference of basin size and soil type.
2. The leaves of agarwood caused by uncomfortable lighting are easy to appear under the condition of long-term lack of light.
3, poor ventilation will also cause the leaves of fragrant wood to fall off, and good ventilation conditions should be maintained.
4. If there are scale insects on the branches and leaves or red spiders on the leaves, you can spray special insecticides for controlling scale insects, such as chlorpyrifos and chlorpyrifos, dicofol and nisolone for controlling red spiders.
Benefits of planting agarwood
