The Latest High-Yield Cultivation Techniques and Methods for White Cardamom
White cardamom is a plant in the ginger family (Zingiberaceae), mainly distributed in the southwestern region of our country. 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 the flow of qi, and warming the middle and stopping vomiting. Now there is also a certain planting area in our country, so how should white cardamom be planted? Below, the editor brings you the high-yield cultivation techniques for white cardamom. Let's take a look!
1. Timely sowing
As just mentioned, 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 disease bacteria, and improve soil fertility. Then harvest the fruit within the appropriate time, poke the seeds out of the fruit, and wash the pulp on the outer 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, 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 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. Properly cover the area around the seedlings with grass to improve the soil's ability to retain moisture and fertilizer, prevent nutrient deficiency from affecting growth, and increase the survival rate of emerged seedlings. After emergence, reasonably build shade sheds to prevent direct sunlight from burning the seedlings. Then, according to the specific growth of the seedlings, thin them appropriately, keeping the row and plant spacing between each seedling at about 13 cm * 6 cm, providing enough growing space for the seedlings. Then, according to soil moisture and weather, water and fertilize appropriately to provide sufficient nutrients and moisture for the seedlings and promote growth.
3. Water and fertilizer management
White cardamom likes to grow in a humid environment and has a relatively large demand for water. If it lacks water during growth, the leaves will dry, shrink, curl and wither. The plant becomes thin and weak, and different adverse phenomena will appear in each growth period, which is not conducive to the growth of white cardamom. Therefore, we must water in time 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 of planting and the initial fruiting stage, apply heavy farmyard manure to promote root group growth and increase the fruiting rate. Appropriately apply topdressing outside the roots and spray foliar fertilizer to meet the nutritional needs of white cardamom growth.
4. Field management
After planting and before the rows close, pay attention to weed control to prevent weeds from competing for the growth nutrients of white cardamom. Weed in time, and when weeding, be careful not to damage the seedlings and roots, so as not to affect the normal nutrient absorption of white cardamom. Then, after harvesting the fruit, pay attention to cleaning the garden, removing old, weak, dead and residual branches as well as pest- and disease-infected branches, and destroying 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 white cardamom cultivation techniques. White cardamom cultivation is relatively simple, but everyone needs to manage it carefully, do a good job in pest and disease prevention, and strengthen basic management work, etc. Enhance the growth ability of white cardamom, increase yield, and expand planting benefits. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
