What should be noted when planting Oldenlandia diffusa? Detailed explanation of cultivation key points

Oldenlandia diffusa is an annual sprawling herbaceous plant and is currently a very important Chinese medicinal material for preventing tumors. Clinically, it can be used to treat a variety of diseases, such as lung-heat asthma and cough, intestinal abscess, venomous snake bites, enteritis, appendicitis and other symptoms. Secondly, it can also enhance the human body's immunity, play a role in inhibiting tumors, and also has an excellent effect on leukemia. So what issues should we pay attention to when planting Oldenlandia diffusa? Let's take a look at the precautions below.

1. Soil

At present, Oldenlandia diffusa in China is mainly distributed in Fujian, Guangdong, Guangxi, Hainan and other areas with relatively mild climate throughout the year, which also shows that its requirements for the growing environment must be areas with a mild climate all year round. The planting site should have relatively low terrain, sufficient sunlight, convenient drainage and irrigation, sufficient soil fertility, and soil containing sufficient organic matter and rich humus is more suitable for planting Oldenlandia diffusa.

2. Time

The planting time of Oldenlandia diffusa is also an aspect worth our attention. Generally speaking, it can be planted in two seasons, namely spring and autumn. When planted in different seasons, its emergence rate and yield vary. The best planting time is from the end of March to the beginning of May each year, followed by the period from mid-August to late August. If we want to plant Oldenlandia diffusa, it is best to complete sowing during these two time periods.

3. Water

Oldenlandia diffusa has relatively strict water requirements, and its water demand during the growth process is also relatively large. After sowing, in order to promote seed emergence, we usually water once in the morning and once in the evening each day, but it should be noted that waterlogging must not occur. After Oldenlandia diffusa emerges, we should keep the soil moist, so appropriate watering is needed. During the rainy season, drainage should be carried out in time to avoid waterlogging or water accumulation. This also means that during the growth process of Oldenlandia diffusa, attention must be paid to both drought prevention and waterlogging prevention.

4. Nutrients

Oldenlandia diffusa has a relatively short growth cycle, so base fertilizer is the key to its growth. Base fertilizer is generally mainly farmyard manure, which can promote plant growth. When the seedlings grow to about 8 to 10 cm, we can appropriately apply 1 jin of manure and urine water as topdressing. In the middle stage of Oldenlandia diffusa growth, we only need to topdress according to its growth condition. Another thing to note is that if we want to harvest twice, we only need to continue fertilizing after harvesting, so that Oldenlandia diffusa can be promoted to grow again.

5. Pests and diseases

Oldenlandia diffusa has strong resistance, so there are almost few pests and diseases throughout its growth process, but this does not mean there is no harm from pests and diseases. What we should pay attention to is the impact of pests such as cutworms and tobacco cutworms. For cutworms, we can use trichlorfon mixed with stir-fried bean cakes or wheat bran for trapping and killing. For tobacco cutworms, we can use insect trap lamps for trapping and killing, or use 5% fipronil suspension concentrate 40ml/667m2 or BT preparation 200~250g/667m2 for poisoning and killing.

Under normal planting conditions, the yield of processed Oldenlandia diffusa per mu after harvest is about 600 to 1,000 jin, so its yield is also very considerable. If everyone is interested in planting, you can follow us to obtain more detailed interpretations of planting techniques.
