A Detailed Explanation of the Planting Techniques and Methods for Alpinia oxyphylla
Alpinia oxyphylla, also known as Yizhi, is a perennial herbaceous plant in the Zingiberaceae family, with a certain distribution in the tropical provinces of China. The fruit of Alpinia oxyphylla is the main medicinal part, and it has various effects such as benefiting the spleen and stomach and regulating vital energy. It can be used to treat problems such as diarrhea, vomiting and decreased appetite, and its medicinal value is relatively high. Its planting area in China is relatively wide, so how should Alpinia oxyphylla be planted? Below, the editor brings you the planting techniques for Alpinia oxyphylla. Let's take a look together!
1. Land selection and land preparation
Alpinia oxyphylla is a plant that relatively prefers water and shade, so when choosing a planting site, we should choose mountain forest areas with weak light and sufficient water sources. As long as the soil has sufficient fertility, normal drainage and irrigation, and strong permeability, Alpinia oxyphylla can grow normally. After selecting the land, do a good job of plowing and digging holes, pay attention to the specifications of the planting holes, and ensure that Alpinia oxyphylla has sufficient growing space. During land preparation, apply it together with base fertilizer, and the base fertilizer should mainly be fully decomposed farmyard manure. Fully mix and stir the base fertilizer with the topsoil to increase soil fertility, promote the growth of Alpinia oxyphylla seeds, and improve the germination rate.
2. Seed collection and germination promotion
The maturity period of Alpinia oxyphylla is around the middle of May each year, and then select plants with long fruit spikes, large fruits, high yield and strong flavor as the mother plants. Then harvest the fruits and take out the seeds, wash the seeds with clean water, and remove the mucus and pulp. Because the seed coat of Alpinia oxyphylla is relatively hard, germination promotion work should be done well before planting. First soak the seeds in cold water for about 60 minutes, then put them into water at about 45 degrees to soak for half an hour. Then take them out and put them into cold water to soak for a full day and night, allowing the seeds to absorb enough water, and then put them on a sand bed for germination promotion. Control the temperature at about 25 degrees, and after about half a month the seeds gradually germinate. At this time, sow the germinated seeds into the seedbed.
3. Seedling management
The soil of the seedling bed should be ensured to be soft and fertile, with normal drainage and irrigation. First finely rake the soil, apply sufficient base fertilizer, then make beds, control the specifications of the beds well, and ensure the bed surface is flat. If the seedling bed is not shady enough, then build a shade shed to ensure that the seedling bed has at least 65% shade. Then control the sowing density and sow at the right time. After sowing, cover with fine soil and grass material, water thoroughly, prevent direct sunlight, improve soil water retention, and promote seed germination. About a week after sowing, the seeds begin to break through the soil, and after 3 weeks they are almost fully emerged. At this time, remove the grass in time. If the grass is removed too late, it will affect the growth of the seedlings and lead to the formation of leggy seedlings.
4. Field management
During the seedling stage, regular intertillage and weeding work should be done, and it should be carried out together with topdressing work. When topdressing, follow the principle of applying small amounts frequently. When the seedlings grow about 3 true leaves, start topdressing work, and then apply topdressing once every half a month. As the number of topdressings increases, the fertilizer concentration can be appropriately increased. When fertilizing, be careful not to let the fertilizer touch the leaves and so on, to prevent the leaves from being damaged. When encountering drought, water appropriately to keep the soil moist and prevent flower and fruit drop in Alpinia oxyphylla. When there is too much water, also pay attention to drainage.
The above is a brief introduction to the planting techniques for Alpinia oxyphylla. During the planting process, we should also carry out appropriate shaping and pruning to enhance the permeability in the garden, increase the flowering and fruiting rate, and promote plant growth. There is also the prevention and control of pests and diseases. These are all tasks that everyone should do well when planting. That is all for today's introduction.
