The Latest Cultivation Techniques and Methods Tutorial for Alpinia oxyphylla
Alpinia oxyphylla, also known as Yizhi, is a perennial herbaceous plant in the ginger family (Zingiberaceae) and is found to some extent in the tropical provinces of China. The fruit of Alpinia oxyphylla is the main medicinal part, with various effects such as strengthening the spleen and stomach and regulating vital energy. It can be used to treat problems such as diarrhea, vomiting and loss of appetite, and its medicinal value is relatively high. It is planted over a fairly wide area in China, so how should Alpinia oxyphylla be cultivated? Below, the editor brings you the cultivation techniques for Alpinia oxyphylla. Let's take a look!
1. Site selection and land preparation
Alpinia oxyphylla is a plant that relatively prefers water and shade, so when choosing a planting site, we should select mountain forest areas with weak light and sufficient water sources. Soil with sufficient fertility, normal drainage and irrigation, and strong permeability is enough for Alpinia oxyphylla to grow normally. After selecting the site, do a good job of plowing and digging planting holes, paying attention to the specifications of the planting holes to ensure that Alpinia oxyphylla has sufficient growing space. During land preparation, apply base fertilizer together, mainly fully decomposed farmyard manure. Mix and stir the base fertilizer thoroughly 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 mid-May each year, and then plants with long fruit ears, large fruits, high yield and strong flavor are selected as 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 place them in water at about 45 degrees to soak for half an hour. Then take them out and soak them in cold water for a full day and night, allowing the seeds to absorb enough water, and then place them on a sand bed for germination promotion. Keep the temperature at about 25 degrees, and after about half a month the seeds gradually germinate. At this point, sow the germinated seeds into the seedbed.
3. Seedling management
The soil of the seedling bed must be guaranteed to be soft and fertile with normal drainage and irrigation. First finely till and rake the soil, apply sufficient base fertilizer, then make beds, control the bed specifications well, and ensure the bed surface is flat. If the seedling bed is not shady enough, then a shade shed should be built 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 point, the grass should be removed in time. If the grass is removed too late, it will affect the growth of the seedlings and cause leggy seedlings to form.
4. Field management
During the seedling stage, regular cultivating and weeding work should be done, and it should be carried out together with topdressing. When topdressing, follow the principle of applying small amounts frequently. When the seedlings grow about 3 true leaves, topdressing should begin, and then topdressing should be applied 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 leaves and other parts come into contact with the fertilizer, to prevent the leaves from being damaged. In times of 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 cultivation techniques for Alpinia oxyphylla. During the cultivation process, we should also appropriately shape and prune to enhance the permeability within the plantation, increase the flowering and fruiting rate, and promote plant growth. There is also the prevention and control of pests and diseases, all of which are tasks everyone should do well when planting. That is all for today's introduction. This article is for reference only.
