Detailed Explanation of Key Points for High-Yield Cultivation Techniques of White Cardamom
White cardamom is a plant in the ginger family (Zingiberaceae), mainly distributed in the southwestern region of China. It prefers to grow in warm, humid soil rich in organic matter with strong permeability. It is a very traditional Chinese medicinal herb with various effects such as resolving dampness and promoting qi flow, and warming the middle to stop vomiting. It now has a certain planting area in China as well, so how should white cardamom be cultivated? Below, the editor brings you the high-yield cultivation techniques for white cardamom. Let's take a look together!
1. Sowing at the Right Time
As mentioned earlier, white cardamom has suitable soil for growth, so before planting we must first select good soil, then do a good job of disinfection and fertilization, eliminate soil pests and diseases, and improve soil fertility. Then harvest the fruit at the appropriate time, poke the seeds out of the fruit, and wash the pulp off the seed coat clean. Then spread the seeds out to sun-dry them. After sun-drying, place the seeds in moist sand for germination. When about 80% of the seeds have sprouted (white tips showing), they can be sown. When sowing, control the sowing density and sow in rows, keeping the row spacing at about 12 cm. When the seedlings grow about 3 true leaves, thin them out to ensure healthy growth of each seedling. After about 11 months, transplant them.
2. Seedling Management
When the seedlings emerge, do a good job of seedling management. Appropriately cover the area around the seedlings with grass to improve the soil's moisture and fertility retention capacity, prevent nutrient deficiency from affecting growth, and increase the emergence survival rate of the seedlings. After emergence, reasonably build shade sheds to prevent direct sunlight from scorching the seedlings. Then, according to the specific growth of the seedlings, appropriately thin them out, keeping the row and plant spacing between each seedling at about 13 cm * 6 cm, providing sufficient growth space for the seedlings. Then, according to soil moisture and weather, appropriately water and fertilize to provide sufficient nutrients and water for the seedlings and promote growth.
3. Water and Fertilizer Management
White cardamom likes to grow in humid environments and has a relatively large demand for water. If it lacks water during growth, the leaves will dry, shrink, and curl up. The plant will be thin and slender, and different adverse phenomena will appear at various growth stages, which is not conducive to the growth of white cardamom. Therefore, we must water timely to increase the air humidity in the field, but during the rainy season we must also pay attention to drainage to prevent waterlogging from rotting the flowers and roots. Then, in the early stage before planting and the early fruiting stage, apply heavy farmyard manure to promote root group growth and increase the fruiting rate. Appropriately apply root-outside fertilizer and spray foliar fertilizer to meet the nutritional needs of white cardamom's growth.
4. Field Management
After planting and before the rows close, pay attention to doing a good job of weeding to prevent weeds from seizing the growth nutrients of white cardamom. Weed timely, and when weeding, be careful not to damage the seedlings and roots, to prevent affecting the normal nutrient absorption of white cardamom. Then, after harvesting the fruit, pay attention to doing a good job of clearing the garden, removing old, weak, dead, and diseased branches and pest-damaged branches, etc., to destroy the overwintering sites of pathogens. Finally, do a good job of artificial pollination, because the success rate of self-pollination in white cardamom is not high, so artificial pollination is needed to increase the flowering and fruiting rate of white cardamom.
The above is a brief introduction to the cultivation techniques of white cardamom. The cultivation of white cardamom is relatively simple, but everyone needs to manage it carefully, do a good job of pest and disease prevention, and strengthen basic management work, etc. Enhance the growth ability of white cardamom, increase yield, and expand planting benefits. That's all for today's introduction. This article is for reference only, and I hope it can help everyone!
