What conditions are needed for growing Alpinia oxyphylla?
Alpinia oxyphylla has fairly strong medicinal effects, and a certain amount of it is grown in our country. However, Alpinia oxyphylla is a tropical plant, so many places cannot grow it. In fact, the yield of Alpinia oxyphylla in our country is not very high, mainly because Alpinia oxyphylla has great requirements for its growing environment. So what kind of environment does growing Alpinia oxyphylla need? Below, the editor will bring you Alpinia oxyphylla's requirements for soil, temperature and light. Let's take a look!
1. Temperature
Alpinia oxyphylla is a warmth-loving crop. During cultivation, the annual average temperature must be kept above 20 degrees so that the growth of Alpinia oxyphylla will not be affected. It is best to keep the temperature at around 25 degrees. Especially during the flowering and fruiting period, if the temperature is below 20 degrees, the flowering rate will be greatly reduced, and below 11 degrees, flowering stops. Also, during the young fruit stage, if the temperature is too low, it will cause a large amount of fruit drop, while the cold resistance of the fruit in the middle and late stages increases somewhat. However, if it is 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 its normal growth. When planting, choose a place with a certain degree of shade; it can be intercropped among various forest trees. However, the light requirements of Alpinia oxyphylla change continuously as it grows. Before flowering and fruiting, the shade degree within the forest should be kept at about 75%, and after maturity it should be appropriately lowered to 65%. At this time, if it is too shaded, it is easy to cause excessive vegetative growth of branches and leaves, reduce tillering, and lower the fruiting rate. We must also control the shade degree according to seasonal changes to ensure the healthy growth of Alpinia oxyphylla.
3. Humidity
Alpinia oxyphylla likes to grow in a moist 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 garden, especially during the flowering and fruiting period of Alpinia oxyphylla. If there is too much standing water, it is easy to cause flower rot and flower drop, fruit rot and fruit drop, etc. It inhibits the flower bud differentiation of Alpinia oxyphylla and reduces the flowering and fruiting rate. However, if it is in a dry environment for a long time, the growth rate of the plant will become extremely slow, and in severe cases it will stop growing and gradually die. Water 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 soft soil rich in humus and with strong water and fertilizer retention. Keep the soil at around 5, and by no means choose severely eroded, hollow, and barren clay soil, which is 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, Alpinia oxyphylla has relatively poor wind resistance. If it encounters strong wind, it is very easy to lodge, so when planting, improve the wind resistance of Alpinia oxyphylla and plant it together with shelterbelts as much as possible to reduce the threat of wind.
