High-yielding planting techniques of cardamom

Cardamom is a plant of Zingiberaceae, which is mainly distributed in southwest China. It likes to grow in warm, moist, organic matter-rich and permeable soil. Is a very traditional Chinese medicine, with dampness and qi, warm to stop vomiting and other functions. Now there is a certain planting area in our country, so how to grow cardamom? The following editor brings you the high-yield planting technology of cardamom, let's have a look!

1. Sowing seeds at the right time

Just said that cardamom is suitable for growing soil, so we should first select the soil before planting, and then do a good job of disinfection and fertilization to eliminate soil diseases and insect pests and improve soil fertility. Then harvest the fruit in an appropriate time, poke the seed out of the fruit and wash the pulp of the seed skin. Then spread out the seeds for drying, and after drying the seeds, put the seeds in wet sand to promote germination. When about 80% of the seeds are exposed, they can be sown. When sowing, the sowing density should be controlled and the row spacing should be controlled at about 12 cm. When the seedlings grow about 3 true leaves, seedlings are carried out to ensure the healthy growth of each seedling, and transplant is carried out after about 11 months.

2. Seedling management

When the seedlings are unearthed, it is necessary to do a good job in seedling management, properly cover grass around the seedlings, improve the ability of soil moisture and fertilizer, prevent the lack of nutrition from affecting the growth, and improve the survival rate of seedlings. After being unearthed, it is necessary to build a shade shed reasonably to prevent direct sunlight and cause burns of seedlings. Then, according to the specific growth of the seedlings, the row spacing between the seedlings should be controlled at about 13 cm * 6 cm, so as to provide enough growth space for the seedlings. And then according to soil moisture, weather and other appropriate watering and fertilization, for the seedlings to improve sufficient nutrient water and promote growth.

3. Water and fertilizer management

Cardamom likes to grow in a moist environment, and the demand for water is relatively large. Lack of water in the growth process will cause the leaves to shrink and curl up. The plant is thin and slender, and there will be different bad phenomena in each growth period, which is not conducive to the growth of cardamom. Therefore, we must water in time to improve the air humidity in the field, but we should also pay attention to drainage in the rainy season to prevent water from rotting flowers and roots. Then in the early stage of planting and early fruiting period, we should re-apply farm manure to promote group growth, improve fruit rate, appropriate extra-root topdressing, spraying foliar fertilizer to meet the growth and nutritional needs of cardamom.

4. Field management

Before the row is closed after planting, attention should be paid to weeding to prevent weeds from grabbing the growth and nutrition of cardamom. It is necessary to weed in time, and be careful not to harm the seedlings and roots when weeding, so as not to affect the normal nutrition absorption of cardamom. Then after harvesting the fruit, we should pay attention to do a good job in clearing the garden, remove the old, weak and withered branches and branches of diseases and insect pests, and destroy the overwintering place of bacteria. Finally, artificial pollination should be done well, because the success rate of self-pollination of cardamom is not high, so artificial pollination is necessary to improve the flowering and fruiting rate of cardamom.

The above is a brief introduction to the planting technology of cardamom, the cultivation of cardamom is relatively simple, but we need to manage carefully, do a good job in pest prevention, strengthen basic management and so on. Enhance the growth ability of cardamom, increase the yield and expand the planting benefit. That's all for today's introduction. This article is for reference only. I hope it can help you all.
