What are the latest cultivation conditions for Alpinia oxyphylla?
Alpinia oxyphylla has relatively strong medicinal effects and is grown on a certain area in China. However, Alpinia oxyphylla is a tropical plant, so it cannot be grown in many places. In fact, the yield of Alpinia oxyphylla in China is not very high, mainly because Alpinia oxyphylla has great requirements for its growing environment. So what kind of environment does Alpinia oxyphylla need for cultivation? Below, the editor will bring you the requirements of Alpinia oxyphylla for soil, temperature, and light. Let's take a look!
1. Temperature
Alpinia oxyphylla is a temperature-loving crop. During cultivation, the annual average temperature must be kept above 20°C so that the growth of Alpinia oxyphylla will not be affected. It is best to keep the temperature at around 25°C. Especially during the flowering and fruiting period, if the temperature is below 20°C, the flowering rate will be greatly reduced, and when it is below 11°C, flowering stops. In addition, during the young fruit stage, if the temperature is too low, it will cause a large number of fruit drops, while the cold resistance of the fruit in the middle and late stages increases somewhat. However, if it is kept in a low-temperature environment for a long time, it will cause the plant to die or even fail to sprout.
2. Light
During growth, Alpinia oxyphylla should not be exposed to direct sunlight. It prefers shade, and a shaded environment is an important factor in ensuring the normal growth of Alpinia oxyphylla. When planting, choose a place with a certain degree of shade, and it can be intercropped among various forest trees. However, the light requirement of Alpinia oxyphylla changes continuously as it grows. Before flowering and fruiting, the shade density within the forest should be kept at around 75%, and after maturity it should be appropriately reduced to 65%. At this time, if it is too shaded, it is likely to cause excessive vegetative growth of branches and leaves, reduce tillering, and lower the fruiting rate. We should also control the shade density according to seasonal changes to ensure the healthy growth of Alpinia oxyphylla.
3. Humidity
Alpinia oxyphylla likes to grow in a humid environment. Its air humidity content is as high as 88%, and the soil moisture content is also around 28%. However, there should not be standing water in the plantation, especially during the flowering and fruiting period of Alpinia oxyphylla. If there is too much standing water, it can easily cause flower rot and flower drop, fruit rot and fruit drop, and so on. It inhibits the flower bud differentiation of Alpinia oxyphylla and reduces the flowering and fruiting rate. However, if it is in a drought environment for a long time, the growth rate of the plant will become extremely slow, and in severe cases growth will stop and the plant will gradually die. Moisture is the key factor determining the yield of Alpinia oxyphylla, so it is necessary to ensure that there is sufficient water around the planting site for watering and irrigation.
4. Soil
Alpinia oxyphylla has relatively strong adaptability. In the wild state, its requirements for soil are not very strict. Except that it cannot grow on extreme soils such as saline-alkali land and sandy land, it can develop normally in most soils. However, if you want to increase the yield of Alpinia oxyphylla and enhance its growth, then you should still choose soil that is loose, rich in humus, and strong in water and fertilizer retention. Keep the soil at around 5, and by no means choose clay with severe soil erosion, hollows, and poor fertility, as these are very unfavorable to the growth of Alpinia oxyphylla.
In addition, wind volume also has a certain effect on the growth of Alpinia oxyphylla. When the wind speed is too high, it will increase the evaporation rate of water and disrupt the water balance within Alpinia oxyphylla. Moreover, the wind resistance of Alpinia oxyphylla is relatively poor. If it encounters strong wind, it is very easy for it to lodge, so when planting, the wind resistance of Alpinia oxyphylla should be improved, and it should be planted together with shelterbelts as much as possible to reduce the threat of wind.
