The latest growth environment of Houttuynia cordata Thunb

Houttuynia cordata was a famous controversial wild vegetable. People liked it very much, and those who didn't liked it very much. In the southwest region, people liked this wild vegetable very much. The most common one was cold salad. It had always been dug wild, but now the wild could no longer meet the market demand, so artificial cultivation began. If artificial cultivation wants to grow well, it is inevitable to study the wild environment of Houttuynia cordata. Artificial cultivation should meet those growth needs according to their growth characteristics.

1. Climate

It grows in subtropical climate, especially in Yunnan, which is mainly distributed in Hunan, Hubei, Guizhou, Sichuan, Chongqing and Yunnan. Likes moist, cool growing environments. It often grows in valleys, fields and ridges.

2. Temperature

Strong adaptability to temperature, rhizomes can germinate above 12 degrees, grow poorly below 25 degrees below 12 degrees, and grow at a high temperature of 35 degrees without death. It is possible to winter below zero. Above-ground tissue can grow at 13 degrees, but it is best to grow between 13 and 18 degrees.

3. Humidity

The root system is shallow, not widely distributed, and the root hair is not much, so the water requirements are quite strict. It is necessary to keep the soil moist and not lack water, preferably 70% to 80%. The air humidity is about 60% to 80%. Water shortage and drought are easy to die. Although the wild sometimes sees extreme drought and still survives, but that is wild, artificial cultivation should try to provide a good environment.

4. Light

For light requirements are not strict, but prefer weak light, but also more tolerant of shade, because under strong light, the corresponding temperature will rise, affecting growth, and easy to evaporate water, so that the soil is dry, root water loss, so growth is not very good.

5. Soil

It is best to grow in loose soil, hardening is not conducive to the growth of rhizomes, if it is sticky, rain and moisture, it is easy to blacken and rot, but the sand soil is not good, water loss is fast, and growth is poor. It is best to grow in sandy loam, keep fertilizer and water well. It grows in neutral soil and mainly supplements nitrogen and potassium.

Houttuynia cordata mainly grows well in moist, cool, weak light and neutral sandy loam, so it is necessary to provide a suitable growth environment as much as possible in actual cultivation, which also has many benefits for yield.
